Detailed ways

In order to enable those in the technical field to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

The screen-to-body ratio of an electronic device refers to the proportion of the screen area to the front area of the entire machine. Figure 1 is a schematic diagram of the front area of an electronic device. The area of area A (the front light-emitting area of the screen) is S1, the area of the front area of the whole machine is S2, and the periphery of area A is the frame area B. The screen-to-body ratio of the electronic device is: Screen-to-body ratio = S1/S2*100%. Therefore, in order to increase the screen-to-body ratio of an electronic device, the frame of the electronic device is usually designed to be narrower to make the electronic device more beautiful.

At present, in order to achieve the goal of increasing the screen-to-body ratio of electronic devices, some conceptual products such as single-sided curved screens, left and right double-sided curved screens, waterfall screens, and surround screens have appeared in electronic devices. These products mainly use organic light-emitting diodes. The flexible characteristics of the (Organic Light-Emitting Diode, OLED) display screen can visually achieve the effect of reducing the frame by changing the fitting form of the display screen, thereby achieving the purpose of increasing the screen-to-body ratio of the display screen. However, for OLED displays The screen itself and the bezels have not been reduced, which is not conducive to further improving the screen-to-body ratio of the display. Therefore, for the higher screen-to-body ratio of OLED displays, how to reduce the frame of OLED displays is extremely important.

In related technologies, achieving narrow borders is mainly achieved by compressing design rules (design rules). For the left and right borders, the main compression is GOA (Gate on Array), source supply voltage (VSS), the effective packaging area of thin film encapsulation (TFE), cathode (Cathode) contact area, etc.; for the bottom border, the main compression and extension The line width and spacing of pad wiring (Fanout wiring), VSS, TFE effective packaging area, Cathode contact area, etc.

Existing technology achieves narrow borders mainly by compressing design rules. However, the compression space of design rules is limited, and compressing design rules increases process difficulty and reduces yield. Therefore, a pixel drive circuit is inserted into the original area of the screen, and a light-emitting unit is set up in the original frame area. The pixel drive circuit is connected to the original frame area through indium tin oxide (ITO, Indium tin oxide) wiring. The light-emitting unit is connected, so that the peripheral circuit can be placed under the light-emitting unit in the original frame area, thereby reducing the area of the frame.

After a long period of research, the inventor found that although the above method can increase the screen-to-body ratio, the impedance will increase because the light-emitting pixels in the edge area are connected to the pixel driving circuit inserted in the non-edge area through transparent wiring. Furthermore, when the same grayscale content is displayed in two areas, the same voltage is applied, but the brightness of the light-emitting pixels in the two areas is different, that is, the edge area cannot reach the brightness it wants to display (the grayscale that needs to be displayed). Since the non-edge area does not need to be connected through wiring, it can normally display the brightness it is intended to display. In turn, the display brightness of the edge area and the non-edge area will be uneven, affecting the display effect.

In response to the above problems, the inventor proposed the image display method, device, electronic equipment and storage medium provided by the embodiments of the present application, which can improve the problem caused by the relatively high impedance between the light-emitting pixels and the pixel driving circuit in some areas of the screen. Problems with poor display effects, thereby improving the display effect of the screen. The specific image display method will be described in detail in subsequent embodiments.

The scenarios involved in the embodiments of this application are first introduced below.

For example, please refer to FIG. 2 and FIG. 3 at the same time. The display area 200 of the screen 20 of the electronic device includes a first area 210 and a second area 220. The first area 210 is the area where the edge of the display area is located, that is, the first area. 210 is at the edge of the display area, and the second area 220 is an area in the display area 200 other than the first area 210 . The second area 220 is provided with a plurality of first light-emitting pixels 201 distributed in an array, and a plurality of first pixel driving circuits 202 distributed in an array. The plurality of first pixel driving circuits 202 correspond to the plurality of first light-emitting pixels 201 in a one-to-one manner. , and the first light-emitting pixels 201 are directly connected to the first pixel driving circuit 202 to drive each first light-emitting pixel 201 to emit light; in addition, the first area 210 is provided with a plurality of second light-emitting pixels 203 distributed in an array, and the second area A plurality of second pixel driving circuits 204 are also inserted into 220. The plurality of second light-emitting pixels 203 correspond to the plurality of second pixel driving circuits 204 one-to-one, and because the second light-emitting pixels 203 and the second pixel driving circuit 204 are far apart, Therefore, the second light-emitting pixel 203 and the second pixel driving circuit 204 are connected through transparent wiring.

Among them, the first light-emitting pixel 201 and the second light-emitting pixel 203 are used to emit light, and can be light-emitting elements such as micro-LED, organic light-emitting diode (OLED), inorganic light-emitting diode, etc. In this embodiment, the first light-emitting pixel 101 and the second light-emitting pixel 102 include three different colors of light-emitting pixels as an example. The three colors may be red (R), green (G) and blue respectively. (B). It can be understood that the above numbers are only used for illustrative purposes and are not used to limit the protection scope of this embodiment.

The first pixel driving circuit 202 and the second pixel driving circuit 204 are used as pixel driving circuits for driving the first light-emitting pixel 201 and the second light-emitting pixel 202 to emit light respectively. The pixel driving circuit may include a storage capacitor and a plurality of switching elements. The switching elements It can be any type of transistor, for example, a bipolar junction transistor (BJT), a field effect transistor (Field Effect Transistor, FET), or a thin film transistor (ThinFilm Transistor, TFT), etc.

Optionally, the transparent traces include: indium tin oxide ITO traces or indium zinc oxide IZO traces. It can be understood that both ITO material and IZO material are transparent materials. Therefore, the connection between the second pixel driving circuit 204 and the second light-emitting pixel 203 in the first area 210 is realized through ITO wiring or IZO wiring, which can ensure that the The amount of light transmitted in an area 210. Moreover, the resistance of ITO materials and IZO materials is low, so they can ensure the normal operation of the light-emitting pixels. Of course, the specific material of the transparent wiring is not limited, and it can also be made of other materials. It only needs to ensure the light transmittance and low impedance.

Further, please refer to FIG. 4. The first pixel driving circuit 202 and the second pixel driving circuit 204 in FIG. 4 are collectively referred to as the pixel driving circuit 230. The electronic device also includes a peripheral circuit 240. The peripheral circuit 240 and the pixel driving circuit 230 are electrically connected. Connection; The orthographic projection of the peripheral circuit 240 on the display plane of the screen at least partially overlaps the orthographic projection of the second light-emitting pixel 203 in the first area on the display plane. The peripheral circuit 240 may be a circuit for providing scanning control signals and light emission control signals to the pixel driving circuit 230. It may be located at the edge of the screen 20, and the peripheral circuit may be GOA, Fanout, etc. Since the orthographic projection of the peripheral circuit 240 on the display plane 300 of the screen 20 at least partially overlaps with the orthographic projection of the second light-emitting pixel 203 in the first area on the display plane 300 , the display of the peripheral circuit 240 on the screen 20 can be reduced. area outside the area, thereby achieving the effect of reducing the border.

Optionally, the edge positions of the screen of the electronic device can be adopted in the above manner, thereby reducing the size of the borders on the left and right sides and the lower side, thereby realizing an electronic device with narrow borders.

Since the light-emitting pixels in the first area are connected to the pixel driving circuit in the second area through transparent wiring, and the light-emitting pixels in the second area are directly connected to their corresponding pixel driving circuits, therefore, the light-emitting pixels in the first area are The impedance between the pixel and the connected pixel driving circuit will be greater than the impedance between the light-emitting pixel in the second area and the connected pixel circuit. That is to say, the impedance between the light-emitting pixels in the second area and the pixel circuit connected to it is a normal impedance, so the correct brightness can be displayed when displaying content, while the impedance between the light-emitting pixels in the first area and the pixel circuit connected to it is normal. The impedance is relatively large and therefore does not render the correct brightness when displaying content. Therefore, in the image display method provided by the embodiment of the present application, compensation is performed for the grayscale data of the first area, so that when the electronic device displays an image, the first area of the screen can present a correct grayscale.

The image display method provided by the embodiment of the present application will be introduced in detail below with reference to the accompanying drawings.

Please refer to FIG. 5 , which shows a schematic flowchart of an image display method provided by an embodiment of the present application. In a specific embodiment, the image display method is applied to the above-mentioned electronic device. The process shown in Figure 5 will be described in detail below. The image display method may specifically include the following steps:

Step S110: Obtain the first grayscale data corresponding to the first area and the second grayscale data corresponding to the second area in the image to be displayed.

In the embodiment of the present application, when the electronic device displays content, it can obtain the image to be displayed, and compensate the grayscale data corresponding to the first area according to the grayscale data of the image to be displayed, thereby avoiding the problem of luminescence caused by the first area. The impedance between the pixel and the connected pixel driving circuit is relatively high, resulting in the inability to present the original gray scale of the corresponding area in the image to be displayed. Wherein, the electronic device can determine the grayscale data corresponding to the first area from the grayscale data of the image to be displayed, and use it as the first grayscale data; determine the grayscale data corresponding to the second area from the grayscale data of the image to be displayed. grayscale data and use it as the second grayscale data.

In some implementations, the image to be displayed may be any frame to be displayed during the operation of the electronic device. For example, when the electronic device is running a game application in the foreground, the image to be displayed is the game screen of the game application to be displayed; for example, when the electronic device is playing a video, the image to be displayed may be a video frame to be displayed. Of course, the image display method provided by the embodiments of the present application is not limited to the scenarios illustrated here.

In some implementations, the grayscale data of the image to be displayed includes the grayscale value of each pixel. The electronic device can obtain the grayscale value of each pixel point for the image data of the image to be displayed, thereby obtaining the grayscale data of the image to be displayed. When the electronic device determines the grayscale data corresponding to the first area from the grayscale data of the image to be displayed, it can determine the image area in the image to be displayed that matches the position of the first area, and obtain the grayscale data of the image area. , to obtain the grayscale data corresponding to the first area; similarly, the electronic device can determine the image area in the image to be displayed that matches the position of the second area, and obtain the grayscale data of the image area, and obtain the grayscale data corresponding to the second area. Corresponding grayscale data.

In some embodiments, the processor of the electronic device can determine the grayscale data of the image to be displayed, input the grayscale data of the image to be displayed to the panel display driver chip (Display Driver Integrated Circuit, DDIC) of the screen, and then display it on the panel. The driver chip executes the image display method provided by the embodiment of the present application, that is, executes steps S110 to S140 to realize the display of the image to be displayed.

Step S120: Determine the gray-scale compensation parameters corresponding to each gray-scale value in the first gray-scale data according to the gray-scale compensation mapping table corresponding to the current brightness level of the screen. The gray-scale compensation mapping table includes different gray scale values. The grayscale compensation parameter corresponding to the level value.

In this embodiment of the present application, after the electronic device determines the first gray-scale data corresponding to the first area and the second gray-scale data corresponding to the second area, it can target the gray-scale data corresponding to the first area, Compensation parameters are determined to compensate the grayscale data of the first area. Among them, the electronic device may be preset with a grayscale compensation mapping table, and the electronic device may determine the grayscale compensation parameters corresponding to each grayscale value in the grayscale data corresponding to the first region according to the grayscale compensation mapping table. The level value is the gray level value of each pixel in the content of the first image corresponding to the first area; the gray level compensation parameter can be the gray level value after compensation for the gray level value, or can be used to compensate the gray level value. The compensation value is not limited here.

In addition, since the brightness level will also affect the display of the screen, the electronic device can determine the compensation parameters corresponding to each gray level value in the first gray level data based on the gray scale compensation mapping table corresponding to the current brightness level. Understandably, the screen usually has multiple brightness levels. Each brightness level has a maximum brightness and a minimum brightness of 0. The maximum brightness of each brightness level can be set by yourself. For example, if there are 10 brightness levels, Then the maximum values of each brightness level can be: 1000, 800, 600, 500, 400, 300, 200, 100, 50 and 2nit (nit). Each brightness level is divided from 0 to the maximum brightness according to the index 2.2 It is 256 grayscale (0-255), 0 grayscale corresponds to 0nit, and 255 grayscale corresponds to the maximum brightness of each brightness gear. Therefore, inputting the same grayscale value under different brightness gears will result in different brightness. Therefore, in the embodiment of the present application, the electronic device can determine the compensation parameters corresponding to each grayscale value in the first grayscale data based on the grayscale compensation mapping tables of different brightness levels.

In some embodiments, the electronic device may be provided with gray scale compensation mapping tables corresponding to different brightness levels. When the electronic device performs step S120, it may determine the gray-scale compensation mapping table corresponding to the current brightness level from the gray-scale compensation mapping tables corresponding to different brightness levels.

In some implementations, the above-mentioned gray scale compensation mapping table may be stored in the DDIC of the screen. Since the memory space in the DDIC is limited, the gray scale compensation mapping table corresponding to some brightness levels can be stored in the DDIC. When the electronic device determines the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data according to the grayscale compensation mapping table corresponding to the current brightness level of the screen, the electronic device can determine the grayscale compensation parameters corresponding to the stored grayscale compensation mapping table based on the grayscale compensation mapping table. bit, convert the compensation parameters in the stored gray-scale compensation mapping table, and obtain the gray-scale compensation parameters corresponding to each gray-scale value in the first gray-scale data.

In some embodiments, the above-mentioned gray scale compensation mapping table may be a test content that controls the first area to display the corresponding gray scale value in advance when the screen is at a corresponding brightness level, and adjusts the gray scale value of the content so that the first The gray scale presented in the area matches the original gray scale of the test content, so that the mapping relationship between different gray scale values and gray scale compensation parameters at the corresponding brightness level can be obtained.

In some embodiments, since the voltage input to the light-emitting pixels is usually small when displaying low-grayscale content at a low brightness level, resulting in a difference in the brightness of the screen perceived by the user, therefore, the electronic device displays the content to be displayed at a low brightness level. When displaying an image, it can be determined whether the current brightness level is lower than the preset brightness level, and whether the grayscale value in the first grayscale data is the first preset grayscale value; if the current brightness level is lower than the preset brightness level bit, and the grayscale value in the first grayscale data is lower than the preset grayscale value, it means that when the image to be displayed is currently displayed, if no compensation is performed, the display brightness of the first area will not reach the originally intended value. The brightness of the display (the gray scale of the image that needs to be displayed), therefore, step S120 and subsequent steps can be performed to ensure that the first area can present the brightness originally intended to be displayed. Among them, the preset brightness level can be a level where the display brightness in the first area may not reach the originally intended display brightness when the screen displays content. For example, it can be a level with a maximum brightness of 100 nit and a level with a maximum brightness of less than 100 nit. Gear level; the default grayscale value can be used as the input grayscale value when displaying content on the screen. The display brightness may not reach the grayscale value originally intended to be displayed. For example, it can be 64 grayscale and 64 Grayscale below grayscale.

Step S130: Based on the grayscale compensation parameters corresponding to the respective grayscale values, perform grayscale compensation on the respective grayscale values to obtain compensated third grayscale data.

In the embodiment of the present application, after obtaining the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data, compensation can be performed for each grayscale value, thereby obtaining each compensated grayscale value, and Each compensated gray level value is used as the third gray level data.

In some implementations, if the grayscale compensation parameter is the grayscale value after compensation for the grayscale value, then the grayscale compensation parameter corresponding to each grayscale value can be directly used as each compensated grayscale value; if the grayscale value The compensation parameter is the compensation value for the grayscale value, and the grayscale value can be compensated based on the compensation value. For example, one of the grayscale values in the first area data is 40, and its corresponding compensation value is 10, then after compensation The grayscale value is: 40+10=50.

Step S140: Display the image to be displayed based on the second grayscale data and the third grayscale data. The third grayscale data is used when the screen displays the image to be displayed, The gray scale presented in the first area is matched with the first gray scale data.

In the embodiment of the present application, after each grayscale value in the first grayscale data is compensated, the image to be displayed can be displayed based on the second grayscale data and the third grayscale data. The DDIC of the screen can use the third grayscale data corresponding to the first area and the second grayscale data corresponding to the second area as input grayscale data to display the image to be displayed. Since the grayscale data in the first area has been compensated, the compensated grayscale value causes the grayscale presented in the first area to be the same as the original first grayscale data (i.e., the grayscale originally intended to be presented) when the screen displays the image to be displayed. ) matching, so that the first area can present a correct gray scale, avoid uneven display between the first area and the second area, and ensure the display effect of the screen.

In the image display method provided by embodiments of the present application, the display area of the screen of the electronic device includes a first area and a second area, and the impedance between the light-emitting pixels in the first area and the connected pixel driving circuit is greater than that in the second area. The impedance between the light-emitting pixels and the connected pixel drive circuit. Therefore, when the electronic device displays the image to be displayed, the grayscale data corresponding to the content of the first area in the image to be displayed uses the grayscale corresponding to the current brightness level. Compensation mapping table, after determining the grayscale compensation parameters, grayscale compensation is performed, and the second area does not need to be compensated. Therefore, when the screen displays the image to be displayed, the grayscale presented in the first area is consistent with the image to be displayed. The original gray scale matching corresponding to the content of the first area can improve the problem of poor display effect caused by the relatively high impedance between the light-emitting pixels and the pixel driving circuit in some areas of the screen, thereby improving the display effect of the screen. .

Please refer to FIG. 6 , which shows a schematic flowchart of an image display method provided by another embodiment of the present application. The image display method is applied to the above-mentioned electronic equipment. The above-mentioned gray-scale compensation mapping table includes gray-scale compensation parameters corresponding to multiple gray-scale values. The process shown in Figure 6 will be described in detail below. The image display method can be Includes the following steps:

Step S210: Obtain the first grayscale data corresponding to the first area and the second grayscale data corresponding to the second area in the image to be displayed.

In this embodiment of the present application, reference may be made to the content of the foregoing embodiments for step S210, which will not be described again here.

Step S220: If each grayscale value in the first grayscale data matches any grayscale value among the plurality of grayscale values, then according to the grayscale compensation parameters corresponding to the plurality of grayscale values , determine the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data.

In order to reduce the workload in constructing the grayscale compensation mapping table in the early stage and save storage space, the grayscale compensation mapping table in the aforementioned embodiments may include grayscale compensation parameters corresponding to multiple grayscale values, that is, multiple grayscale compensation parameters. A scale value is a partial grayscale value among all possible grayscale values. Optionally, multiple grayscale values can be evenly distributed within the grayscale value range.

In this embodiment of the present application, some of the gray-scale values in the first gray-scale data may match the gray-scale values in the gray-scale compensation mapping table, while some of the gray-scale values may not match. For example, The gray-scale values in the first gray-scale data include: 10, 15, 20, 21, and 26, and the gray-scale values in the gray-scale compensation mapping table match the gray-scale values in the first gray-scale data include 10, 15, 20 and 25, then the grayscale value 26 in the first grayscale data may not match any of the above-mentioned plurality of grayscale values. Therefore, it can be first determined whether each grayscale value in the first grayscale data matches any grayscale value among the plurality of grayscale values. If each grayscale value in the first grayscale data matches If any grayscale value among the plurality of grayscale values matches, the grayscale compensation mapping table can be directly used to find the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data.

Step S230: If there is a grayscale value in the first grayscale data that does not match any of the plurality of grayscale values, obtain the grayscale value in the first grayscale data that matches the plurality of grayscale values. The grayscale value that does not match any of the grayscale values is used as the first grayscale value.

Step S240: Obtain the grayscale values other than the first grayscale value in the first grayscale data as the second grayscale value.

In the embodiment of the present application, if there is a grayscale value in the first grayscale data that does not match any of the multiple grayscale values, it means that only some of the grayscale values in the first grayscale data can be directly obtained from Find the corresponding gray-scale compensation parameters in the gray-scale compensation mapping table. Therefore, it is possible to obtain the grayscale value in the first grayscale data that does not match any grayscale value among the plurality of grayscale values as the first grayscale value, and to obtain the first grayscale value in the first grayscale data except the first grayscale value. The grayscale value other than the value is used as the second grayscale value, and then the grayscale compensation parameter is determined for the first grayscale value, and the grayscale compensation parameter is determined for the second grayscale value.

Step S250: Obtain the third grayscale value and the fourth grayscale value adjacent to the first grayscale value among the plurality of grayscale values, where the plurality of grayscale values are in order from small to large. arrangement.

When compensating for the first gray-scale value, it is possible to determine the third gray-scale value and the fourth gray-scale value adjacent to the first gray-scale value among the above-mentioned plurality of gray-scale values arranged in order from small to large. value, so as to determine the gray-scale compensation parameter corresponding to the first gray-scale value according to the gray-scale compensation parameters corresponding to the third gray-scale value and the fourth gray-scale value in the gray-scale compensation mapping table.

Step S260: According to the grayscale compensation parameters corresponding to the plurality of grayscale values, determine the grayscale compensation parameter corresponding to the second grayscale value, the grayscale compensation parameter corresponding to the third grayscale value and the fourth grayscale value. The grayscale compensation parameter corresponding to the level value.

After determining the third grayscale value and the fourth grayscale value adjacent to the first grayscale value, the third grayscale value can be determined according to the grayscale compensation parameters corresponding to the plurality of grayscale values in the grayscale compensation mapping table. The grayscale compensation parameter corresponding to a grayscale value. Furthermore, the gray scale compensation parameter corresponding to the third gray scale value and the gray scale compensation parameter corresponding to the fourth gray scale value are determined. The gray scale compensation parameter corresponding to the third gray scale value and the gray scale compensation parameter corresponding to the fourth gray scale value are determined. Used to obtain the grayscale compensation parameter corresponding to the first grayscale value.

Step S270: Determine the gray scale compensation parameter corresponding to the first gray scale value according to the gray scale compensation parameter corresponding to the third gray scale value and the gray scale compensation parameter corresponding to the fourth gray scale value.

In the embodiment of the present application, after obtaining the gray scale compensation parameter corresponding to the third gray scale value and the gray scale compensation parameter corresponding to the fourth gray scale value, the gray scale compensation parameter corresponding to the third gray scale value and the gray scale compensation parameter corresponding to the fourth gray scale value can be obtained. The gray scale compensation parameters corresponding to the four gray scale values determine the gray scale compensation parameters corresponding to the first gray scale value.

In some implementations, the grayscale compensation parameter corresponding to the first grayscale value can be determined through difference operation. For example, the third grayscale value is G1, the fourth grayscale value is G2, the first grayscale value is G3, the grayscale compensation parameter corresponding to the third grayscale value is P1, and the grayscale compensation parameter corresponding to the fourth grayscale value is The parameter is P2, and the grayscale compensation parameter corresponding to the first grayscale value is P3, then it satisfies:

(P2-P1)/(G2-G1)＝(P3-P1)/(G3-G1)

From this, P3 can be calculated, that is, the grayscale compensation parameter corresponding to the first grayscale value is obtained.

It can be understood that the above-mentioned first gray-scale value may be one, or may be multiple. If there are multiple first gray-scale values, the corresponding gray-scale compensation parameter may be obtained in the above manner for each first gray-scale value. After obtaining the grayscale compensation parameters corresponding to the first grayscale value and the compensation parameters corresponding to the second grayscale value, the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data are obtained.

Step S280: Based on the grayscale compensation parameters corresponding to the respective grayscale values, perform grayscale compensation on the respective grayscale values to obtain compensated third grayscale data.

Step S290: Display the image to be displayed based on the second grayscale data and the third grayscale data. The third grayscale data is used when the screen displays the image to be displayed, The gray scale presented in the first area is matched with the first gray scale data.

Therefore, the problem of poor display effect caused by the relatively high impedance between the light-emitting pixels and the pixel driving circuit in some areas of the screen can be improved, thereby improving the display effect of the screen; in addition, , the gray-scale compensation mapping table can only include gray-scale compensation parameters corresponding to some gray-scale values, and the gray-scale compensation parameters corresponding to gray-scale values that do not exist in the gray-scale compensation mapping table are obtained through calculation, which can reduce the gray-scale obtained in the early stage. This step compensates the workload of the mapping table and saves the storage space of the screen's DDIC.

Understandably, since the display duration of each frame is different under different screen refresh rates, and the brightness perceived by the user is affected by the turn-on duration of each light-emitting pixel, if the same grayscale value is input under different screen refresh rates, then It will make the brightness different.

In some embodiments, the electronic device may be provided with grayscale compensation mapping tables corresponding to different screen refresh rates and brightness gears, that is, there are grayscale compensation mapping tables corresponding to different brightness gears under each screen refresh rate, or it may be It is understood that under each brightness level, there are grayscale compensation mapping tables corresponding to different screen refresh rates. When the electronic device performs step S320, it can determine the grayscale compensation mapping table corresponding to the current screen refresh rate and the current brightness gear from the grayscale compensation mapping tables corresponding to different screen refresh rates and brightness gears.

Step S330: Based on the grayscale compensation parameters corresponding to the respective grayscale values, perform grayscale compensation on the respective grayscale values to obtain compensated third grayscale data.

Step S340: Display the image to be displayed based on the second grayscale data and the third grayscale data. The third grayscale data is used when the screen displays the image to be displayed, The gray scale presented in the first area is matched with the first gray scale data.

In the embodiment of the present application, the contents of steps S330 and S340 may refer to other embodiments, and are not limited here.

The image display method provided by the embodiment of the present application takes into account that the screen refresh rate of the screen will also affect the display. Therefore, when the electronic device displays the image to be displayed, the current screen refresh rate and the grayscale compensation corresponding to the current brightness level are used. Mapping table, grayscale compensation is performed after determining the grayscale compensation parameters, and the second area does not need to be compensated. This can better improve some areas of the screen. Due to the relatively high impedance between the light-emitting pixels and the pixel drive circuit, The resulting problem of poor display effect will improve the display effect of the screen.

Step S420: Obtain the target compensation mapping table corresponding to the current brightness level from the grayscale compensation mapping tables of different brightness levels corresponding to the preset screen refresh rate.

In the embodiment of the present application, considering that when the screen is at different screen refresh rates, it will also affect the display of the screen. Therefore, when the electronic device compensates for the first grayscale data corresponding to the first area, it can also be based on the current state of the screen. The screen refresh rate determines the grayscale compensation parameters corresponding to the first grayscale data.

Among them, the grayscale compensation mapping table can be stored in the DDIC of the screen. The grayscale compensation mapping table corresponding to each brightness level under the preset screen refresh rate can be stored in the DDIC to save the storage space of the DDIC. When determining the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data, the target corresponding to the current brightness level can be obtained from the grayscale compensation mapping table of different brightness levels corresponding to the preset screen refresh rate. Compensation map. The preset screen refresh rate may be one, for example, a commonly used screen refresh rate for electronic device screens is 60 Hz (hertz); or it may be multiple, for example, 30 Hz, 60 Hz, 90 Hz, 120 Hz, etc.

Step S430: If the current screen refresh rate is the preset screen refresh rate, determine the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data according to the target compensation mapping table.

In this embodiment of the present application, if the current screen refresh rate is the preset screen refresh rate, the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data can be determined directly according to the target compensation mapping table. It can be understood that if there are multiple preset screen refresh rates, the grayscale corresponding to each grayscale value in the first grayscale data is determined according to the target compensation mapping table corresponding to the preset screen refresh rate that the current screen refresh rate matches. compensation parameters.

It should be noted that the embodiments of the present application can also be combined with the foregoing embodiments, that is, the target compensation mapping table only includes grayscale compensation parameters corresponding to some grayscale values, and the first grayscale data is determined by the method of the foregoing embodiments.

Step S440: If the current screen refresh rate is not the preset screen refresh rate, obtain the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data according to the target compensation mapping table.

In this embodiment of the present application, if the current screen refresh rate is not the preset screen refresh rate, the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data cannot be determined directly from the above-mentioned target compensation mapping table. In this case, the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data can be obtained first according to the target compensation mapping table, so as to determine the final compensation parameters for the third grayscale based on the grayscale compensation parameters obtained through the target compensation mapping table.

Optionally, the target compensation mapping table corresponding to the preset screen refresh rate that is closest to the current screen refresh rate can be obtained, and based on the target compensation mapping table, the gray scale corresponding to each gray scale value in the first gray scale data can be obtained Compensation parameters to ensure the accuracy of compensation for the first grayscale data.

Step S450: Adjust the grayscale compensation parameters corresponding to each grayscale value according to the preset adjustment relationship between the current screen refresh rate and the preset screen refresh rate.

In the embodiment of the present application, a preset adjustment relationship between the current screen refresh rate and the preset screen refresh rate may be stored in advance, and the preset adjustment relationship is the adjustment relationship of the gray scale compensation parameter. Using this preset adjustment relationship, adjusting the grayscale compensation parameters corresponding to each grayscale value obtained above can obtain the parameters used for subsequent grayscale compensation for each grayscale value.

In some implementations, the preset adjustment relationship may be an adjustment function, and the adjustment function may be a linear function, a quadratic function, etc., which is not limited here. For example, the adjustment function can be a one-time function. The preset screen refresh rate is 60Hz and the current screen refresh rate is 50Hz. Then Y=K*x+B, where Y is the grayscale compensation parameter corresponding to the grayscale value at the current screen refresh rate. , x is the grayscale compensation parameter corresponding to the grayscale value under the preset screen refresh rate (that is, the grayscale compensation parameter determined according to the above target compensation mapping table), K and B can be obtained through testing in advance, that is, by adjusting K and B , until the grayscale compensation parameters determined by this function are used to compensate the grayscale data corresponding to the first area under the current screen refresh rate, and the original brightness can be displayed. It is understandable that K and B may be different between different screen refresh rates and the preset screen refresh rate. That is, different K and B are obtained through testing for different screen refresh rates and the preset screen refresh rate.

Step S460: Based on the grayscale compensation parameters corresponding to the respective grayscale values, perform grayscale compensation on the respective grayscale values to obtain compensated third grayscale data.

Step S470: Display the image to be displayed based on the second grayscale data and the third grayscale data. The third grayscale data is used when the screen displays the image to be displayed, The gray scale presented in the first area is matched with the first gray scale data.

In the embodiment of the present application, the contents of steps S460 and S470 may be referred to other embodiments, and will not be described again here.

The impedance between the light-emitting pixels and the connected pixel drive circuit. Therefore, when the electronic device displays the image to be displayed, the gray-scale compensation mapping table is used to determine the gray-scale compensation parameters and then perform gray-scale compensation, while the second area does not need to be performed. Compensation, thus, can improve the problem of poor display effect caused by the relatively high impedance between the light-emitting pixels and the pixel driving circuit in some areas of the screen, thereby improving the display effect of the screen; in addition, the grayscale compensation mapping table When only part of the screen refresh rate is set, and the screen is at a non-preset screen refresh rate, the grayscale compensation parameters of the grayscale value at the non-preset screen refresh rate are obtained through calculation, which can reduce the cost of obtaining the grayscale compensation mapping table in the early stage. workload, as well as saving screen DDIC storage space.

Please refer to FIG. 9 , which shows a schematic flowchart of an image display method provided by yet another embodiment of the present application. This image display method is applied to the above-mentioned electronic device. The process shown in Figure 9 will be described in detail below. The image display method may specifically include the following steps:

The screen refresh rate corresponds one to one.

In this embodiment of the present application, there may be multiple preset screen refresh rates in the previous embodiment. When determining the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data, multiple preset screen refresh rates may be used.

In this embodiment of the present application, if the current screen refresh rate is not the preset screen refresh rate, the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data cannot be determined directly from the above-mentioned target compensation mapping table. In this case, two screen refresh rates adjacent to the current screen refresh rate may be used among multiple preset screen refresh rates arranged in ascending order. For example, if multiple preset screen refresh rates are arranged from small to large: 30Hz, 60Hz, 90Hz and 120Hz, and the current screen refresh rate is 75Hz, then the first screen refresh rate and the second screen refresh rate can be 60Hz and 90Hz respectively. .

Step S550: Determine the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data according to the target compensation mapping table corresponding to the first screen refresh rate among the plurality of target compensation mapping tables, as the Describe the first compensation parameter corresponding to each grayscale value.

In the embodiment of the present application, after the above-mentioned first screen refresh rate and second screen refresh rate are determined, the first grayscale data can be determined according to the target compensation mapping table corresponding to the current brightness level under the first screen refresh rate. The gray-scale compensation parameters corresponding to each gray-scale value in the screen are used as the first compensation parameters corresponding to each gray-scale value; similarly, the target compensation mapping table corresponding to the current brightness level under the second screen refresh rate can be determined. The grayscale compensation parameters corresponding to each grayscale value in the first grayscale data are used as the second compensation parameters corresponding to each grayscale value.

Step S570: Based on the first compensation parameter corresponding to each gray scale value and the second compensation parameter corresponding to each gray scale value, determine the gray scale compensation parameter corresponding to each gray scale value.

In the embodiment of the present application, after determining the first compensation parameter corresponding to each gray scale value and the second compensation parameter corresponding to each gray scale value, the first compensation parameter corresponding to each gray scale value and each The second compensation parameter corresponding to the grayscale value determines the grayscale compensation parameter corresponding to each grayscale value, that is, the grayscale compensation parameter finally used to compensate each grayscale value of the first grayscale data.

Therefore, when the electronic device displays the image to be displayed, the gray-scale compensation mapping table is used to determine the gray-scale compensation parameters and then perform gray-scale compensation, while the second area does not need to be performed. Compensation, thus, can improve the problem of poor display effect caused by the relatively high impedance between the light-emitting pixels and the pixel driving circuit in some areas of the screen, thereby improving the display effect of the screen; in addition, the grayscale compensation mapping table When only part of the screen refresh rate is set and the screen is at a non-preset screen refresh rate, the grayscale compensation parameters obtained through the grayscale compensation mapping table under the set screen refresh rate can be further calculated.

Since the trace lengths of the light-emitting pixels at different positions in the first area may be different, there may be a large impedance difference between the light-emitting pixels and the pixel driving unit at different positions. For example, please refer to Figure 11. On the screen When a solid color image with a grayscale value is displayed, different areas within the first area present different grayscales. In this case, in order to ensure the display effect, the first area can be divided into sub-areas, and compensation is performed for the first grayscale data of each sub-area. The number of multiple sub-regions does not need to be limited. For example, please refer to Figure 11 again. The number of sub-regions can be eight, including Block1 to Block8. Of course, the number of sub-regions can also be more.

In the embodiment of the present application, the electronic device can be provided with a grayscale compensation mapping table corresponding to each subregion for each subregion. When actually determining the grayscale compensation parameters corresponding to each grayscale value in the first grayscale data, you can According to the current screen refresh rate corresponding to each sub-region and the gray-scale compensation mapping table corresponding to the current brightness level, the gray-scale compensation parameters corresponding to each gray-scale value in the first gray-scale data corresponding to each sub-region are determined, thus obtaining Gray scale compensation parameters corresponding to each gray scale value in the gray scale data corresponding to the first area. Optionally, the grayscale compensation mapping table corresponding to each sub-region may include a mapping relationship between grayscale values and grayscale compensation parameters under different screen refresh rates and brightness levels.

Of course, when the grayscale compensation mapping table is constructed in advance, the grayscale compensation mapping table corresponding to each subregion can be obtained by testing for each subregion.

It should be noted that the implementation methods in the embodiments of the present application can also be combined with other embodiments, that is, in the solutions of other embodiments, compensation can be performed for the grayscale data of each sub-region in the first region.

The impedance between the light-emitting pixels and the connected pixel drive circuit. Therefore, when the electronic device displays the image to be displayed, it uses the gray-scale compensation mapping table corresponding to the current brightness level to determine the gray-scale compensation parameters and then perform gray-scale compensation. The second area does not need to be compensated. Therefore, the problem of poor display effect caused by the relatively high impedance between the light-emitting pixels and the pixel driving circuit in some areas of the screen can be improved, thereby improving the display effect of the screen; in addition, , when performing gray-scale compensation on the gray-scale data corresponding to the first region, the gray-scale compensation is performed on the gray-scale data corresponding to each sub-region according to the gray-scale compensation mapping table corresponding to each sub-region in the first region, thereby improving the The accuracy of grayscale compensation further improves the display effect of the screen.

The orthographic projection on the plane at least partially overlaps, that is, part of the peripheral circuit is arranged below the light-emitting pixels in the first area, so that the size of the frame can be reduced. In this case, since the light-emitting pixels in the second area are directly connected to the pixel driving unit, the impedance between the light-emitting pixels and the pixel driving unit is small, which usually does not affect the display effect, that is, the second area can correctly to achieve the required brightness. Therefore, this feature can be used to construct a grayscale compensation mapping table.

Among them, the electronic device can control the screen to display the test image of the target grayscale value at the current brightness level. The test image may be a solid color image to ensure that the grayscale values at each position in the first region in the test image are the same as the grayscale values at each position in the second region. Alternatively, the target grayscale value may be a grayscale value lower than the preset grayscale value in the foregoing embodiment, whereby the grayscale compensation parameters can be determined in a targeted manner.

The grayscale value of the area, and the grayscale value of the second area, until the grayscale value of the first area in the photographed image matches the grayscale value of the second area, then the adjustment of the grayscale value displayed in the first area is stopped. When , the grayscale compensation parameters corresponding to the above target grayscale values can be obtained. The grayscale compensation parameter may be the grayscale value when the adjustment is stopped, or the difference between the grayscale value when the adjustment is stopped and the target grayscale value, which is not limited here.

Step S740: Return to the step of controlling the screen to display the test image of the target grayscale value at the current brightness level until grayscale compensation parameters corresponding to different grayscale values are obtained.

In the embodiment of the present application, you can return to step S710, display test images with different grayscale values, and repeat the above steps, so that grayscale compensation parameters corresponding to different grayscale values can be obtained.

Step S750: Construct the gray-scale compensation mapping table according to the gray-scale compensation parameters corresponding to the different gray-scale values.

It should be noted that the above grayscale compensation mapping table is constructed for the current brightness level in the aforementioned embodiment. The grayscale compensation mapping table corresponding to other brightness levels can be constructed in the same manner.

In addition, the method for constructing the grayscale compensation mapping table provided in the embodiments of this application can also be combined with the foregoing embodiments, and only needs to be constructed for the grayscale compensation mapping table in the foregoing embodiments. For example, if you only test the gray-scale compensation parameters of the mapping for some gray-scale values, you only need to test and obtain the gray-scale compensation parameters corresponding to this part of the gray-scale values through the above method; for another example, if you test each sub-region in the first area, To construct a grayscale compensation mapping table for a region, you only need to build a grayscale compensation mapping table for each region through the above method.

In addition, the above-mentioned steps S710 to step S750 may also be executed by the test equipment. That is to say, after the test equipment obtains the above-mentioned gray-scale compensation mapping table through testing, it then sends the gray-scale compensation mapping table to the electronic device, and the electronic device then transmits the gray-scale compensation mapping table to the electronic device. for storage.
