Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

The organic light emitting diode (Organic Light Emitting Diode, OLED) display panel is gradually increasing its market share due to its advantages of high sensitivity, high contrast ratio, wide viewing angle, low power consumption, and thin volume.

When the OLED display panel is used as the display panel of the hidden camera solution, in order to achieve higher transmittance, the high transmittance area on the OLED display panel needs to be different from the non-high transmittance area. film material and driving method. For example, the anode and cathode materials used in the high transmittance area are transparent conductive film materials, the non-high transmittance area uses metal materials, and the transmittance of the transparent conductive film material is higher than that of the metal material; the high transmittance area uses passive materials In the driving method, the non-high transmittance region adopts the active driving method. Compared with the active driving method, the passive driving method does not need to install thin film transistors, so the transmittance is high.

Due to the difference in film material and driving method (film structure) between the high transmittance area and the non-high transmittance area, the service life of the high transmittance area is lower than that of the non-high transmittance area. Over time, the loss of the high transmittance area is higher than that of the non-high transmittance area, resulting in the non-uniform display of the high transmittance area and the non-high transmittance area.

It is worth noting that the high transmittance area mentioned above can be used to hide other components such as light sensors in addition to hiding the front camera.

At least one embodiment of the present disclosure provides a display control method, which is applied to a display panel. FIG. 1 is a schematic structural diagram of a display panel according to an exemplary embodiment. Referring to FIG. 1 , the display panel 100 includes a first display area 101 and a second display area 102 , the second display area 102 surrounds the first display area 101 , and the first display area 101 is close to one side of the second display area 102 side settings. The transmittance of the first display area 101 is higher than that of the second display area 102 , that is, the first display area 101 is the aforementioned high transmittance area, and the second display area 102 is the aforementioned non-high transmittance area. FIG. 2 is a schematic diagram of the application of the display panel in FIG. 1. Referring to FIG. 2, the display panel 100 is applied in a terminal device 10 (such as a mobile terminal). In the terminal device 10, the position corresponding to the first display area 101 can be set before components 20 such as cameras or light sensors.

FIG. 3 is a hierarchical structure diagram of the display panel 100 . Referring to FIG. 3 , the display panel 100 includes a substrate 110 , an array structure 120 on the substrate 110 (eg, a glass substrate), an organic light-emitting material layer 130 and a cathode layer 140 in sequence. Wherein, the difference in service life of the first display area 101 and the second display area 102 may be caused by at least one factor among the film layer material and the film layer structure. For example, the array structure 120 and the cathode layer 140 of the first display area 101 are made of high transmittance materials, while the array structure 120 and the cathode layer 140 of the second display area 102 are made of general transmittance materials. The service life of the transmittance material is lower than that of the general transmittance material. For another example, the array structure 120 of the second display area 102 includes a thin film transistor array and an anode connected to the thin film transistor array, that is, the second display area 102 adopts an active driving mode, and the array structure 120 of the first display area 101 Only the anode array is included, that is, the first display area adopts the passive driving mode. Due to the difference in the film structure of the two, the service life of the passive driving mode is lower than that of the active driving mode.

It should be noted that, one high transmittance area may be set on the display panel, or two or more high transmittance areas may be set.

FIG. 4 is a flow chart of a display control method according to an exemplary embodiment. Referring to FIG. 4 , the method can be performed by a display panel or a terminal device having the display panel, for example, by a driver circuit in the display panel or a controller in the terminal device, the driver circuit is usually an integrated circuit, and the controller Usually an integrated circuit or a processing chip, the display control method may include:

Here, the first display control parameter may be a parameter used to correct the high transmittance area, and the second display control parameter may be a parameter used to correct the non-high transmittance area. The lifespan is shorter, so its aging degree during use is also higher than that of the non-high transmittance area, and the loss is higher than that of the non-high transmittance area. Therefore, a larger data voltage is required to reach the non-high transmittance area. The same gray-scale effect, that is, the first data voltage corresponding to the same gray-scale is greater than the second data voltage is different.

In this embodiment of the present disclosure, step S11 may be performed periodically, and after step S11 is completed, step S12 is performed within the next cycle according to the display control parameter.

Wherein, the above-mentioned difference in luminance represents the magnitude of the difference between the luminances. If the first display area uses the first data voltage to display the first grayscale, the brightness is the first brightness, and the second display area uses the second data voltage to display the first grayscale when the brightness is the second brightness. The difference (first luminance difference) refers to the absolute value of the difference between the first luminance and the second luminance. If the first display area uses the second data voltage to display the first grayscale, the brightness is the third brightness, and the second display area uses the second data voltage to display the first grayscale when the brightness is the fourth brightness, then the brightness of the two The difference (second luminance difference) refers to the absolute value of the difference between the third luminance and the fourth luminance.

For example, when the display control parameter (the first display control parameter or the second display parameter) is a Gamma curve, step S12 may include: selecting a corresponding data voltage from the Gamma curve according to the grayscale value, and using the selected data voltage to control the pixels to display.

Wherein, at least one means that the display parameters include one, two, three or all of the above four. For example, in this method, the first display control parameter may be determined only according to the display duration, or the first display control parameter may be jointly determined according to the display duration and the brightness corresponding to the grayscale voltage of the binding point, which is not limited in this application .

In step S21, display parameters of the first display area are acquired.

Optionally, the display parameters include at least one of: display duration of the first display area, brightness corresponding to the grayscale voltage at the binding point, chromaticity corresponding to the grayscale voltage at the binding point, and current corresponding to the grayscale voltage at the binding point. Chroma refers to the saturation of a color.

In this implementation, the current display condition of the first display area can be accurately determined through information such as brightness, chromaticity, and current, so that display correction is performed according to the display condition; The worse the display effect is, the above-mentioned display control parameters can also be determined according to the length of the display time.

The display duration is the accumulated display time of the display panel, which is usually recorded by the controller of the display panel or the controller of the mobile terminal. For example, a counter or timer in the controller can be used to record the accumulated display time of the display panel. , When the display panel is turned on, the counter or timer works, and when the display panel is ready to shut down and stop working, the result is stored and recorded. Therefore, when the display parameter includes the display duration, step S21 may include: acquiring the display duration recorded by the controller of the display panel or the controller of the mobile terminal.

Among them, the grayscale of the binding point is usually the grayscale stored in the driving circuit of the display panel in the Gamma curve. Although the Gamma curve corresponds to the data voltage of each grayscale, in order to reduce the space required for storage, usually only a few grayscales are stored in the driving circuit. The data voltages of the grayscales of one binding point, for example, the grayscales of eight binding points, the data voltages of other grayscales can be calculated according to these voltages. The tie-point gray-scale voltage is also the tie-point gray-scale data voltage. Among them, the binding point refers to the key points selected in the gray scale of 0 to 255, such as 31, 63, 95, 127, 159, 191, 223, 255. According to the data of these key points, the driving circuit or controller can calculate Arbitrary grayscale data.

Further, when acquiring display parameters such as the brightness corresponding to the gray-scale voltage of the binding point, the chromaticity corresponding to the gray-scale voltage of the binding point, and the current corresponding to the gray-scale voltage of the binding point, etc., it can be obtained when a monochrome picture is displayed in the first display area. , or it can be acquired when a multi-color picture is displayed in the first display area. The monochromatic picture refers to a red, green or blue picture, and the polychromatic picture refers to a pure color picture obtained by combining at least two of the three monochromatic colors, such as a white picture.

Obtain the display parameters corresponding to the grayscale of the bound point when displaying a monochrome picture. For example, when displaying blue light, obtain the display parameters corresponding to the grayscale of the bound point. At this time, the red sub-pixel and the green sub-pixel in each pixel are all 0 gray level, the blue sub-pixel is a non-zero gray level, so as to display monochrome-blue, and then the display parameters are detected. In the method of obtaining the display parameters corresponding to the grayscales of the binding points when displaying a monochrome picture, different monochrome colors can be displayed in sequence, and then the display parameters are obtained separately, for example, red, green, and blue are displayed in sequence.

When displaying a multi-color picture, the display parameters corresponding to the grayscale of the binding point are obtained. For example, when displaying white light, the display parameters corresponding to the grayscale of the binding point are obtained. At this time, each color sub-pixel in the first display area adopts the same grayscale. to display white light, and then check the display parameters.

When the display parameters of the first display area are detected, the second display area may not be displayed, thereby reducing interference to the display parameters of the first display area.

Brightness or chromaticity can be detected by a photodetection device disposed opposite to the first display area of the display panel and far away from the display surface of the display panel, where the display surface refers to the first display area and the second display area of the display panel that emit light at the same time. One side, that is, the display panel is disposed on the side of the terminal device facing the outside (user). The photodetection device includes at least one of a camera and a light sensor, for example, obtains an electrical signal output by the camera or the light sensor, and converts the electrical signal into at least one of chromaticity and brightness.

It should be noted that, before the camera is used to collect the luminance or chromaticity information of the first display area, the method may further include: calibrating the luminance or chromaticity of the camera, and the calibration process is usually completed at the factory. When the light sensor is used to collect the luminance or chromaticity information of the first display area, the light sensor has the ability to deduct the influence of ambient light on the collected information, and this ability can be realized by an algorithm detected in advance.

In an implementation manner of the embodiment of the present disclosure, when the display parameter includes the luminance corresponding to the tie-point gray-scale voltage or the chromaticity corresponding to the tie-point gray-scale voltage, step S21 may include:

Acquire ambient light information, where the ambient light information is used to indicate the brightness of the ambient light; when the brightness of the ambient light is less than the first threshold, acquire the display parameters of the first display area.

In an implementation manner of the embodiment of the present disclosure, when the display parameter includes the luminance corresponding to the tie-point gray-scale voltage or the chromaticity corresponding to the tie-point gray-scale voltage, step S21 may include:

A display parameter acquisition instruction is output, and the display parameter acquisition instruction is used to instruct the user to place the display panel in an environment with low ambient light brightness; after receiving the user's confirmation instruction, the display parameters of the first display area are acquired.

In this implementation, two implementations of acquiring display parameters are provided, the first is automatic acquisition, and the second is manual acquisition. Through these two methods, the acquisition of display parameters can be realized, so as to provide information for subsequent display. Correction provides the basis. It should be noted that, due to the high transmittance of the first display area, in order to avoid external ambient light from interfering with the display parameters, it is necessary to obtain the display parameters in an environment with no ambient light or a small amount of ambient light, such as at night or at night. dark place.

When the display parameter includes a grayscale voltage corresponding to the binding point, step S21 may include: acquiring the voltage of the detection resistor in the driving circuit of the first display area, and determining the current according to the voltage of the detection resistor. Since the first display area and the second display area are routed separately, the detection resistor can be a resistor (for example, a resistor set on a flexible circuit board) disposed in the driving circuit of the first display area, and the detection resistor can be used Current detection can be achieved. Here, the number of detection resistors may be one or more.

In step S22, the difference between the display parameter of the first display area and the reference display parameter is compared. When the difference exceeds the second threshold, step S23 is performed.

Since the display effect of the first display area and the second display area of the display panel with a shorter display time is the same, or there is little difference, it is not necessary to correct the first display area at this time, but when the display time reaches a certain length, The above-mentioned implementation manner is used to determine when the display correction needs to be performed, so as to avoid the waste of resources when performing display correction on a display panel with a short display duration.

When the difference does not exceed the second threshold, exit the current process. At this time, the first display control parameters of the first display area are the same as the second display control parameters of the second display area, and the display panel has just been put into use. At this time, the loss degree of the first display area is small and no correction is required.

The reference display parameter may be a set of luminance, chromaticity or current detected in advance and stored in the display panel or the mobile terminal. The reference display parameter may also be detected in real time. For example, when the current is used as the display parameter, the reference display parameter may be the current value of the same gray level of the second display area detected in real time. The reference display parameter may also be a fixed value, for example, when the display duration is used as the display parameter, the reference display parameter may be 0.

In step S23, the first display control parameters are determined based on the display parameters of the first display area.

Optionally, the first display control parameter is one of a plurality of Gamma curves, and the plurality of Gamma curves are all stored in the drive circuit of the display panel, and the plurality of Gamma curves correspond to a plurality of different stages respectively, and different stages adopt different The display parameter range indicates that the first display control parameters are determined based on the display parameters of the first display area, including:

Based on the corresponding relationship between the display parameter range and the Gamma curve, a Gamma curve corresponding to the display parameter range in which the display parameter of the first display area is located is determined.

For example, different display stages are represented by different brightness ranges. For example, the first stage brightness ranges from A1 to A2, the second stage brightness ranges from A2 to A3, and so on, where A1, A2, and A3 gradually decrease.

In different Gamma curves, at least some of the gray scales correspond to different data voltages. For display parameters such as brightness, chrominance, and current, the smaller the display parameter range, the larger the data voltage corresponding to the same grayscale in the corresponding Gamma curve. For time, the larger the display parameter range is, the larger the data voltage corresponding to the same grayscale in the corresponding Gamma curve.

Optionally, the first display control parameter is one of a plurality of display correction coefficients, and the plurality of display correction coefficients are all stored in the drive circuit of the display panel, and the plurality of display correction coefficients correspond to a plurality of different stages, and the different stages Using different display parameter ranges to represent, based on the display parameters of the first display area, determine the first display control parameters, including:

Based on the correspondence between the display parameter range and the display correction coefficient, a display correction coefficient corresponding to the display parameter range in which the display parameter of the first display area is located is determined, and the display correction coefficient is used for the Gamma curve used in the first display area Make corrections.

In this implementation, two methods for determining display control parameters based on display parameters of the first display area are provided, one is to directly determine the Gamma curve, and the other is to obtain the Gamma curve used for the first display area For the adjusted coefficient, both methods can obtain a new Gamma curve suitable for the current display panel, thereby ensuring display uniformity.

Further, the method may further include: acquiring the corresponding relationship between the display parameter range and the Gamma curve, or the corresponding relationship between the display parameter range and the display correction coefficient. The process of obtaining the above correspondence can be obtained through a life test.

FIG. 6 is a schematic diagram of Gamma curves at different stages shown in an embodiment of the present disclosure. Referring to FIG. 6 , curve 1 is the initial Gamma curve, and curve 2 is the Gamma curve after a period of use. As time goes by, the required data ( Data) voltage increases. By using different Gamma curves at different times, the display correction of the first display area can be realized.

In the embodiment of the present disclosure, the corresponding relationship between the display parameter range and the display correction coefficient mentioned in the second method may be stored in advance in the controller of the display panel or the controller of the mobile terminal, or may be stored in the controller of the display panel in advance. The controller or the controller of the mobile terminal is generated in real time. For example, the data voltages of the bound grayscales of the first display area in several stages, or the luminance, chrominance or current change fitting functions of the first display area are stored in advance, and the luminance, chrominance or current change fitting functions are luminance, color The fitting function of the change of intensity or current with the display time. Based on the data voltage of the bound point grayscale of the first display area in several stages, or the fitting function of the change of brightness, chromaticity or current of the first display area, the range of display parameters is determined and Displays the correspondence between correction coefficients.

Wherein, determining the corresponding relationship between the display parameter range and the display correction coefficient based on the brightness, chromaticity or current change fitting function of the first display area may be based on the brightness, chromaticity or current change fitting function of the first display area function, and the relationship between luminance, chromaticity, or current and data voltage, to determine the display correction factor. Here, the relationship between luminance, chromaticity or current and data voltage is known in advance. For example, the brightness is proportional to the Nth power of the voltage, where N is the gamma value, and based on this relationship, a display correction coefficient can be determined. For example, Y=X ^2.2 in the initial Gamma curve, Z=X ^2.2×n in the Gamma curve after a period of time, X is the data voltage, Y and Z are the brightness, and n is the display correction coefficient. Based on the brightness change fitting function, the initial brightness Y and the current brightness Z can be determined, and the value of n can be determined based on the above formula, and then the corresponding relationship between the display parameter range and the display correction coefficient can be obtained.

For the method of determining the corresponding relationship between the display parameter range and the display correction coefficient based on the data voltages of the bound grayscales of the first display area in several stages, the corresponding relationship between the luminance, chromaticity, or current and the data voltage can also be determined. The relationship between the display correction coefficient is determined, and the corresponding relationship between the display parameter range and the display correction coefficient is obtained.

The brightness of the first display area in FIG. 7 is generated under the action of the data voltage of the same gray-scale binding point. Referring to FIG. 7, three lines Respectively represent the brightness when displaying red, green, and blue monochrome pictures. It can be seen that the brightness of any color picture gradually decreases with time. It should be noted that FIG. 7 shows the fitting function curves of the brightness of the light emitted by the three different color sub-pixels under the same gray-scale voltage, and it can be seen that the attenuation degrees of different color sub-pixels are different.

Steps S21-S23 may be performed aperiodically. With reference to FIG. 7 , for example, under the action of the data voltage of a certain grayscale, each time the brightness (or chromaticity) of a certain color decreases by a fixed value, steps S21-S23 are performed once. After obtaining the first display control parameter, the display panel only needs to obtain the first display control parameter to control the first display area to display. Wherein, step S22 is an optional step. Steps S21-S23 can also be triggered by an event. For example, when the user turns on the display correction function, steps S21-S23 are executed to obtain the first display control parameter, and then the display panel only needs to obtain the first display control parameter to control the first display. area to display.

When the display panel displays each picture, in addition to acquiring the first display control parameter, it also needs to acquire the second display control parameter. The second display control parameter may be determined in advance or a fixed parameter. For example, the second display control parameters can be determined in advance in the same way as the first display control parameters, and then the second display control parameters are acquired when each picture is displayed. When the second display control parameters are determined, the The display parameters may only include at least one of the display duration and the current corresponding to the gray-scale voltage of the binding point. For another example, the second display control parameter can also be a fixed Gamma curve. In this case, it does not need to be determined in advance. The second display control parameter can be obtained when each picture is displayed. In this case, the second display area can use the internal Compensation completes the display correction, which is realized by changing the circuit structure in the array structure (such as a threshold compensation circuit such as 6T1C).

In step S24, the gray level of each sub-pixel located in the first display area and the gray level of each sub-pixel located in the second display area in the target picture are acquired.

In step S25, the data voltage of each sub-pixel in the first display area of the display panel is determined based on the first display control parameter and the gray scale of each sub-pixel in the first display area; The gray scale of each sub-pixel in the second display area determines the data voltage of each sub-pixel in the second display area of the display panel.

For example, when the display control parameter (the first display control parameter or the second display parameter) is a Gamma curve, step S25 may include: selecting a corresponding data voltage from the Gamma curve according to the grayscale value, and using the selected data voltage to control the pixels to display.

When the display control parameter is a display correction coefficient, step S25 may include: using the display correction coefficient to adjust the Gamma curve used in the first display area; selecting corresponding data from the adjusted Gamma curve according to the grayscale value The selected data voltage is used to control the pixel for display.

Optionally, both the first display control parameter and the second display control parameter include display control parameters corresponding to each color channel.

In this practical manner, by separately correcting the sub-pixels of different colors, the difference in lifetime caused by the difference of the organic light-emitting materials of the sub-pixels of each color is also corrected, and the display uniformity is improved.

In step S26, the determined data voltage of each sub-pixel in the first display area is input into each sub-pixel in the first display area, and the determined data voltage of each sub-pixel in the second display area is input into the first display area. two in each sub-pixel of the display area.
