FIG. 2 is a schematic structural diagram of a display module of an electronic device according to an embodiment of the present application, and FIG. 3 is a cross-sectional structural schematic diagram of the display module of FIG. 2 . As shown in FIG. 2 and FIG. 3 , the display module mainly includes a cover plate 200 and a display screen 210 connected to the cover plate 200 .

The display screen 210 may be a display screen such as an LCD (Liquid Crystal Display, liquid crystal display) or an OLED (Organic Light-Emitting Diode, organic light-emitting diode). The display screen 210 includes a pixel area 211 and a non-pixel area 212. The non-pixel area 212 is also the BM area. The pixels in the pixel area 211 (the objects indicated by the small circle ○ in FIG. 2 ) can be lit to emit light and used for To display an image, a control circuit structure is arranged in the non-pixel area 212, and the control circuit structure is used to control the pixels in the pixel area 211 to emit light, and the non-pixel area 212 cannot emit light.

The cover plate 200 is connected to the display screen 210 by lamination. For example, the cover plate 200 is attached to the display screen 210 through an OCA adhesive layer (Optically Clear Adhesive, optically clear adhesive). An ink layer 220 is printed on the side of the cover plate 200 close to the display screen 210 . The area enclosed by the inner edge 2201 of the ink layer 220 is the ink window area 2204, that is, the area where the display screen of the electronic device can be observed when the screen is bright. The ink layer 220 includes a layered black ink layer 2202 and a white ink layer 2203 . The cover plate 200 , the black ink layer 2202 and the white ink layer 2203 are stacked in sequence. The embodiment in FIG. 3 shows two ink layers. It can be understood that in other embodiments, the number of ink layers can be changed as required. For example, another black ink layer can be provided under the white ink layer 2203 .

The ink layer 220 forms a transparent portion 202 and a frame portion 201 on the cover plate 200 , that is, the ink layer 220 shields the cover plate 200 to form a corresponding frame portion 201 on the cover plate 200 , and the transparent portion 202 overlaps the ink window area 2204 . In some embodiments, the transparent portion 202 may be substantially rectangular, and the frame portion 201 may be substantially annular. The light emitted by the display screen 210 cannot be transmitted through the frame part 201 , so the user cannot see the image displayed on the display screen 210 from the frame part 201 . The transparent part 202 is transparent, the light emitted by the display screen 210 can be transmitted through the transparent part 202 , and the user can see the image displayed on the display screen 210 on the transparent part 202 .

Generally, the vertical projection of the frame portion 201 on the display screen 210 covers the entire non-pixel area 212 . In one embodiment, the pixel area 211 is larger than the ink window area, that is, the vertical projection of the frame portion 201 on the display screen 210 also covers part of the pixel area 211 , so that the pixel area 211 includes the first display area 2112 and blocked area 2111. The blocked area 2111 is the area of the pixel area 211 that is blocked by the frame portion 201 . The first display area 2112 refers to an area that can be observed by a user through the ink viewing window area from the transparent portion 202 of the cover plate 200 when the display screen is in a bright screen state. The boundary line of the first display area 2112 is also the inner edge 2201 of the ink layer 220 , or the boundary line between the frame portion 201 and the transparent portion 202 .

The pixel area 211 is generally expanded by about 0.2 mm on the basis of the ink window. In some embodiments, the boundary of the pixel area 211 is extended by 0.15 mm on the basis of the boundary of the ink window area.

The center line of the first display area 2112, the center line of the ink window area 2204 and the center line of the transparent portion 202 overlap. When a preset image needs to be displayed on the display screen, the preset image is The position displayed on the display screen is set as the position of the first display area 2112. When the display screen is lit, the image displayed in the first display area 2112 is displayed through the transparent part 202, and the image is in the position where the display screen is lit. The transparent portion 202 and the central position of the ink layer viewing window area 2204. However, during the lamination process of the cover plate 200 of the display module and the display screen 210 , the inner edge of the ink layer 220 attached to the cover plate 200 and the inner edge of the non-pixel area 212 are prone to misalignment, resulting in the dislocation of the display screen. Part of the pixels in the first display area 2112 are blocked by the inner edge of the ink layer 220, resulting in a deviation between the center line of the transparent portion 202 of the cover plate 200 and the center line of the image displayed in the first display area 2112 of the display screen. When the display screen is lit, there is a problem that the display image is not centered within the transparent portion 202 . For example, when the display image contains multiple icons, the distance between the edge of one icon and the inner edge of the ink layer may be greater than the distance between the corresponding icon on the other side and the inner edge of the ink layer, which affects the display effect of the electronic device.

For example, please refer to FIG. 4 . FIG. 4 is a schematic cross-sectional structural diagram of the dislocation between the inner edge of the ink layer and the inner edge of the non-pixel area 212 in the display module of FIG. 3 . During the lamination process, the inner edge of the ink layer 220 attached to the cover plate 200 is misaligned with the inner edge of the non-pixel area 212, and the ink layer 220 is offset relative to the non-pixel area 212 by the size of the distance d, which makes the display screen. The respective positions of the ink window area 2204 and the transparent portion 202 are also moved correspondingly by the size of the distance d, and some pixels of the size d of the first display area 2112 of the display screen are blocked by the inner edge of the ink layer 220 , so that the pixels on the display screen that can display images through the ink window area 2204 and the transparent portion 202 move to the second display area 2112 ′, but before the cover plate 200 of the display module is attached to the display screen 210 , the position where the image is displayed on the display screen is the first display area 2112, so that after the cover plate 200 of the display module is attached to the display screen 210, the center line of the transparent portion 202 of the cover plate 200 and the center line of the display screen are formed. The center line of the image displayed in the first display area 2112 deviates, and when the display screen is turned on, the problem that the displayed image is not centered in the transparent portion 202 occurs.

Based on the above problems, the embodiment of the present application provides a display correction method for a display module, which can effectively solve the problem of poor display effect caused by the misalignment between the inner edge of the ink layer on the cover plate and the inner edge of the BM area, Improve the display effect of electronic equipment.

Please refer to FIG. 5. FIG. 5 is a flowchart of an embodiment of a display calibration method for a display module of the present application. The method includes:

Step 500: Receive a correction instruction, the correction instruction is generated according to the first image when it is detected that the preset image is displayed in the display area of the display screen relative to the ink window area of the display module when the offset occurs; the first image is The display module is in a bright screen state to capture an image obtained from the ink window area.

Wherein, the preset image includes an image with a clear boundary, for example, an image whose boundary is a rectangle or a square, or the preset image is a cross target, etc., so that it is convenient to determine the preset through the first image Whether the image is offset relative to the ink window area when displayed in the display area of the monitor. The preset image is an image preset to be displayed on the display screen of the electronic device, and may be stored in the electronic device to which the display module belongs.

The electronic device lights up the display screen of the electronic device, and the display screen displays a preset image, and the first image is obtained by photographing the ink window area of the display module of the electronic device in a bright screen state with a camera device. The photographing range of the photographing device covers the ink window area of the cover plate and the preset image displayed in the display area of the display screen, and the first image includes the ink window area image of the cover plate in the display module and the display module. Preset images in the group displayed in the display area of the monitor. Referring to FIG. 3 , the first image includes the ink window area image of the ink window area 2204 in FIG. 3 and the preset image displayed in the first display area 2112 . The photographing device may be a photographing component of the electronic device, such as a retractable and rotatable photographing component of the electronic device, or a separate photographing device connected to the electronic device in a wired or wireless manner. The photographing device includes a charge-coupled device (Charge-coupled Device, CCD device), for example, a cross target is displayed in the center of the first display area 2112, and the distance from the cross target to the boundary line of the ink window area can be captured by the CCD device. to determine whether the cross target is in the exact center of the ink window area. Among them, the charge-coupled element is called a CCD image sensor, also called an image controller.

According to the acquired first image, when the preset image is displayed in the display area of the display screen, it is determined whether the preset image is offset relative to the ink window area of the display module. For example, the electronic device analyzes whether the geometric center of the preset image and the geometric center of the ink window area image overlap, or by analyzing whether the distances from the geometric center of the preset image to the opposite sides of the ink window area image are consistent, Or by analyzing whether the distances between the boundary lines on the opposite sides of the preset image to the opposite sides of the ink window area image are consistent, if the judgment result is "Yes", it is judged that there are no pixels in the display area that are blocked by the ink layer. , and then determine that the preset image is not offset relative to the ink window area when displayed in the display area, otherwise, determine that there are pixels in the display area that are blocked by the ink layer, and then determine that the preset image is in the display area. When the display area is displayed, it is offset relative to the ink window area.

If the electronic device determines that the preset image is offset relative to the ink window area of the display module, the electronic device generates a correction instruction.

Step 520: Move the position of the preset image according to the correction instruction, so that the geometric center of the preset image overlaps the geometric center of the ink window area.

Specifically, if the electronic device judges that the preset image is offset relative to the ink window area of the display module by analyzing the first image acquired by the electronic device, the preset image is analyzed relative to all the first images through the first image. The offset direction and offset size of the ink window area, and a correction instruction is generated according to the offset direction and offset size, and the correction instruction is used to instruct the electronic device to change the preset image from the offset offset The moving direction moves the distance of the offset size in the opposite direction of the offset direction, and the electronic device moves the position of the preset image according to the offset direction and the offset size according to the correction instruction, so that the preset image The geometric center of the overlaps the geometric center of the ink window area.

For example, please continue to refer to FIG. 4, it is assumed that in the process of laminating the cover plate 200 of the display module and the display screen 210, the inner edge of the ink layer 220 attached to the cover plate 200 is misaligned with the inner edge of the non-pixel area 212, The ink layer 220 is offset by a distance d relative to the non-pixel area 212, so that the respective positions of the ink window area 2204 and the transparent portion 202 on the display screen are also shifted by a distance d. The size d of the first display area 2112 is partially blocked by the inner edge of the ink layer 220, so that the pixels on the display screen that can display the image through the ink window area 2204 and the transparent portion 202 are moved to the second Display area 2112'. If the position of the preset image when displayed on the display screen is set in the first display area 2112, the electronic device acquires the first image, and by analyzing the acquired first image, judges that the preset image is relatively relative to the preset image. The ink window area of the display module is offset, and the offset direction and offset size of the preset image relative to the ink window area are analyzed by the first image to be d. According to the offset direction and offset The size d generates a correction instruction, the correction instruction is used to instruct the electronic device to move the preset image from the first display area 2112 to the second display area 2112', the electronic device according to the received The correction instruction is used to move the position of the preset image from the first display area 2112 to the second display area 2112', so that the geometric center of the preset image is the same as the geometric center of the ink window area. overlapping.

In one embodiment, the step of moving the position of the preset image according to the correction instruction so that the geometric center of the preset image overlaps the geometric center of the ink window area includes:

The color value displayed by each pixel in the display area is adjusted so that the geometric center of the preset image overlaps the geometric center of the ink window area.

Specifically, adjusting the color value displayed by each pixel in the display area so that the geometric center of the preset image overlaps the geometric center of the ink window area means that the preset image is displayed on the display screen During display, according to the offset direction and offset size of the preset image offset relative to the ink window area, the preset image is adjusted to the opposite direction of the offset direction by the distance of the offset size, corresponding to After adjusting the position of the preset image when it is displayed on the display screen, the color value of the corresponding pixel on the display screen is adjusted to the color value of each pixel in the preset image. , when the preset image is displayed on the display screen, the geometric center of the preset image overlaps the geometric center of the ink window area at the position of the display screen.

When the preset image is displayed on the display screen, it is realized by displaying the color value of the image pixel point of the preset image through the pixel point of the display screen. For example, please refer to Table 1, assuming that the preset image contains 4 pixels, each pixel corresponds to a corresponding color value, such as: the color value of the pixel at position a11 in the preset image is A1, and the color of the pixel at position a12 The value is A2, the color value of the pixel at the a13 position is A3, the color value of the pixel at the a14 position is A4, and the pixel color values A1, A2, A3, and A4 and their corresponding positional relationships constitute the preset image.

Table 1

Please continue to refer to FIG. 4, assuming that when the preset image is displayed on the display screen of the electronic device, the position of the preset image on the display screen is preset as the first display area 2112, the first display area It includes pixel points b11 , b12 , b13 and b14 , and the corresponding relationship between the pixel points of the first display area 2112 and the preset image is shown in Table 1.

Suppose that during the lamination process between the cover plate 200 of the display module and the display screen 210 , the inner edge of the ink layer 220 attached to the cover plate 200 and the inner edge of the non-pixel area 212 are misaligned, and the ink layer 220 is relatively non-pixel. The area 212 is shifted by the size of the distance d, the respective positions of the ink window area 2204 and the transparent portion 202 on the display screen are also shifted by the size of the distance d, and the size of the first display area 2112 of the display screen is d. Part of the pixels are blocked by the inner edge of the ink layer 220, so that the pixels on the display screen that can display images through the ink window area 2204 and the transparent portion 202 are moved to the second display area 2112'.

If the position of the preset image when displayed on the display screen is set in the first display area 2112 before the cover plate 200 of the display module is attached to the display screen 210, the preset image passes through the first display area 2112. When a display area 2112 is displayed, the part of the preset image displayed by the pixels of the size d of the first display area 2112 cannot be displayed through the ink window area 2204 and the transparent portion 202 because it is blocked by the ink layer 220 . On the cover plate 200, the electronic device obtains the first image, and by analyzing the obtained first image, it is judged that the preset image is displayed relative to the ink window of the display module when the preset image is displayed in the first display area 2112 of the display screen. If the area is offset, the offset direction and offset size of the preset image relative to the ink window area when displayed in the first display area 2112 through the first image analysis is d, according to the offset direction and the offset size d to generate a correction instruction, the correction instruction is used to instruct the electronic device to move the position of the preset image when displayed on the display screen from the first display area 2112 to the second display area 2112', the electronic device moves the position of the preset image from the first display area 2112 to the second display area 2112' according to the received correction instruction, that is, the second display area is moved to the second display area 2112'. The color value displayed by each pixel in the area 2112' is adjusted to the color value of each pixel of the preset image, so that when the preset image is displayed on the display screen, the geometric center of the preset image is at the location where the preset image is displayed. The position of the display screen overlaps the geometric center of the ink window area.

In one embodiment, the step of moving the position of the preset image according to the correction instruction so that the geometric center of the preset image overlaps the geometric center of the ink window area includes:

According to the correction instruction, control the first preset pixel on the side where the preset image is offset from the ink window area of the display module to be in an off state, and control the first preset pixel on the other side corresponding to the offset side. Two preset pixels are in the lit state, wherein the value of the pixel column of the first preset pixel is the same as the value of the pixel column of the second preset pixel, or the value of the pixel row of the first preset pixel is the same. The numerical value is the same as the numerical value of the pixel row of the second preset pixel.

Specifically, the electronic device obtains the first image of the ink window area when the display module is in a bright screen state through a photographing device, and the electronic device determines, according to the first image, that the preset image is relative to the display module The ink window area of the ink window is offset, and the offset direction and offset size of the preset image offset relative to the ink window area are obtained through the first image, and a correction instruction is generated. According to the correction instruction, the electronic device, When the display screen is in the bright screen state, control the first preset pixel on the side where the preset image is offset relative to the ink window area to be in the off state, and control the first preset pixel on the other side corresponding to the offset side. The second preset pixel is in the lit state, wherein the value of the pixel column of the first preset pixel is the same as the value of the pixel column of the second preset pixel, or the pixel row of the first preset pixel The value of is the same as the value of the pixel row of the second preset pixel.

For example, assuming that the pixel area of a display screen is 100*100 pixels, the display area of the display screen used to display the preset image has 80*80 pixels, that is, a 80*80 pixel is displayed through the display area of the display screen. 80px preset image. Under normal circumstances, the center line of the display area and the center line of the pixel area overlap. For example, to display a solid square with a size of 80*80 pixels in the display area, the pixel area has 10 pixels on each of the four sides according to the direction from the outside to the inside. The row of pixels is not lit, and the 80*80 pixels in the central area of the pixel area except the 10 rows of pixels on each of the four sides are lit. If you want to move the position of the display area where the square is located to one side in the horizontal direction by 5 columns Pixels, you only need to control 5 columns of pixels on one side of the pixel area not to light up, 15 columns of pixels on the other side corresponding to the one side are not lit, and all the pixels of the remaining columns are lit, and the displayed image effect is to place this square in all directions. The above side is shifted by 5 columns of pixels.
