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 schematic sectional structural diagram of the display module of fig. 2. As shown in fig. 2 and 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) or an OLED (organic light Emitting Diode), the Display screen 210 includes a pixel region 211 and a non-pixel region 212, the non-pixel region 212 is a BM region, pixels (objects indicated by small circles ○ in fig. 2) in the pixel region 211 may be lit to emit light and used for displaying an image, and a control circuit structure is disposed in the non-pixel region 212 and used for controlling the pixels in the pixel region 211 to emit light, and the non-pixel region 212 cannot emit light.

The cover plate 200 is connected to the display screen 210 in a stacked manner, for example, the cover plate 200 is attached to the display screen 210 by an OCA (Optically clear adhesive) layer. The side of the cover plate 200 close to the display screen 210 is printed with an ink layer 220. The area enclosed by the inner edge 2201 of the ink layer 220 is an ink window area 2204, which is an area where a display screen of an electronic device can be observed in a bright state. The ink layer 220 includes a black ink layer 2202 and a white ink layer 2203 stacked in layers. Wherein, the cover plate 200, the black ink layer 2202 and the white ink layer 2203 are sequentially stacked. While the embodiment of fig. 3 shows two ink layers, it is understood that the number of ink layers may be varied as desired in other embodiments, for example, another black ink layer may be disposed under 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 covers the cover plate 200 to form the 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. Light emitted from the display screen 210 cannot be transmitted through the bezel portion 201, and thus, a user cannot see an image displayed on the display screen 210 from the bezel portion 201. The transparent portion 202 is light-transmissive, and light emitted from the display screen 210 can be transmitted through the transparent portion 202, and a user can see an image displayed on the display screen 210 at the transparent portion 202.

In general, the vertical projection of the bezel portion 201 on the display screen 210 covers the entire non-pixel area 212. In an embodiment, the pixel region 211 is larger than the ink window region, that is, the vertical projection of the frame portion 201 on the display screen 210 further covers a portion of the pixel region 211, so that the pixel region 211 includes a first display region 2112 and a blocked region 2111. The blocked region 2111 is the region blocked by the bezel portion 201 in the pixel region 211. The first display region 2112 is a region that can be viewed by a user from the transparent portion 202 of the cover 200 through the ink window region when the display screen is in a bright state. The boundary line of the first display region 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 typically extended by about 0.2 mm based on the ink viewing window. In some embodiments, the boundaries of the pixel region 211 are extended 0.15 mm beyond the boundaries of the ink viewing window region.

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 part 202 are overlapped, when a preset image needs to be displayed on a display screen, the position of the preset image displayed on the display screen is set to be the position of the first display area 2112, when the display screen is lightened, the image displayed in the first display area 2112 is displayed through the transparent part 202, and the image is located in the middle of the transparent part 202 and the ink layer window area 2204. However, in the process of attaching the cover plate 200 of the display module to 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 region 212 are easily misaligned, so that a part of pixels of the first display region 2112 of the display screen are shielded by the inner edge of the ink layer 220, a deviation occurs 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 region 2112 of the display screen, and when the display screen is turned on, the displayed image is not centered in the transparent portion 202. For example, when the displayed image is a plurality of icons, the distance between the edge of one icon and the inner edge of the ink layer is 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, referring to fig. 4, fig. 4 is a schematic cross-sectional structure diagram of the misalignment between the inner edge of the ink layer and the inner edge of the non-pixel region 212 in the display module shown in fig. 3, assuming that the inner edge of the ink layer 220 attached to the cover plate 200 and the inner edge of the non-pixel region 212 are misaligned during the process of attaching the cover plate 200 to the display screen 210 of the display module, the ink layer 220 is shifted by a distance d relative to the non-pixel region 212, so that the positions of the ink window region 2204 and the transparent portion 202 on the display screen are correspondingly shifted by the distance d, and a portion of pixels of the first display region 2112 of the display screen are shielded by the inner edge of the ink layer 220, so that the pixels on the display screen capable of displaying images through the ink window region 2204 and the transparent portion 202 are shifted to the second display region 2112', but before the cover plate 200 of the display module is attached to the display screen 210, the position set when 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 part 202 of the cover plate 200 is deviated from the center line of the image displayed in the first display area 2112 of the display screen, and when the display screen is lighted, the problem that the displayed image is not centered in the transparent part 202 occurs.

Based on the above problem, the embodiment of the application provides a display module's display correction method, can effectual solution apron on the printing ink layer inboard edge and the inboard edge in BM district produce the not good problem of display effect that the dislocation leads to, improve electronic equipment's display effect.

Referring to fig. 5, fig. 5 is a flowchart illustrating an embodiment of a display calibration method of a display module according to the present application, the method including:

500, receiving a correction instruction, wherein the correction instruction is generated when a preset image is detected to be deviated relative to an ink window area of a display module when the preset image is displayed in a display area of a display screen according to a first image; the first image is an image obtained by shooting the ink window area when the display module is in a bright screen state.

The preset image comprises an image with a clear boundary, for example, the preset image boundary is a rectangular or square image, or the preset image is a cross target and the like, so that whether the preset image deviates relative to an ink window area when the preset image is displayed in a display area of the display screen or not is conveniently determined through the first image. The preset image is a preset image which is used for being displayed on a display screen of the electronic equipment and can be stored in the electronic equipment to which the display module belongs.

The electronic equipment lights a display screen of the electronic equipment, the display screen displays a preset image, and a photographing device shoots an ink window area of a display module of the electronic equipment in a bright screen state to obtain a first image. The photographing range of the photographing device covers a printing ink window area of the cover plate and a preset image displayed in a display area of the display screen, and the first image comprises the printing ink window area image of the cover plate in the display module and the preset image displayed in the display area of the display screen in the display module. Referring to fig. 3, the first image includes an ink window area image of the ink window area 2204 in fig. 3 and a predetermined 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 may be a separate photographing device connected with the electronic device in a wired or wireless manner. The photographing device includes a Charge-coupled device (CCD device), such as a cross target displayed in the center of the first display region 2112, and the CCD device can capture the distance from the cross target to the border line of the ink window region to determine whether the cross target is in the center of the ink window region. The charge coupled device is called a CCD image sensor, also called an image controller.

And judging whether the preset image deviates relative to an ink window area of the display module when the preset image is displayed in the display area of the display screen according to the acquired first image. For example, the electronic device determines that no pixel point exists in the display region and is shielded by the ink layer if the determination result is yes, and then determines that the preset image is not shifted relative to the ink window region when the display region displays, or determines that the pixel point exists in the display region and is shielded by the ink layer if the determination result is yes.

And if the electronic equipment judges that the preset image deviates relative to the ink window area of the display module, the electronic equipment generates a correction instruction.

And step 520, moving the position of the preset image according to the correction instruction to enable the geometric center of the preset image to be overlapped with the geometric center of the ink window area.

Specifically, if the electronic device obtains the first image through analysis, it is determined that the preset image deviates from an ink window area of the display module, the deviation direction and the deviation size of the preset image relative to the ink window area are analyzed through the first image, a correction instruction is generated according to the deviation direction and the deviation size, the correction instruction is used for indicating the electronic device to move the preset image from the deviated deviation direction to the direction opposite to the deviation direction by the distance of the deviation size, and the electronic device moves the position of the preset image according to the deviation direction and the deviation size according to the correction instruction, so that the geometric center of the preset image overlaps with the geometric center of the ink window area.

For example, with continued reference to fig. 4, it is assumed that, during the process of attaching the cover plate 200 of the display module to 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 region 212, the ink layer 220 is shifted from the non-pixel region 212 by a distance d, so that the positions of the ink window region 2204 and the transparent portion 202 on the display screen are shifted by the distance d, and a portion of pixels of the first display region 2112 of the display screen is shielded by the inner edge of the ink layer 220, so that the pixels of the display screen capable of displaying images through the ink window region 2204 and the transparent portion 202 are shifted to the second display region 2112'. If the position of the preset image when displayed on the display screen is set in the first display area 2112, the electronic equipment acquires a first image, judges that the preset image deviates relative to the ink window area of the display module by analyzing the acquired first image, analyzing the offset direction and the offset size of the preset image relative to the ink window area as d through the first image, generate a correction instruction for instructing the electronic device to move the preset image from the first display region 2112 to the second display region 2112' according to the offset direction and offset dimension d, the electronic equipment moves the position of the preset image from the first display region 2112 to the second display region 2112' according to the reception of the correction instruction, so that the geometric center of the preset image is overlapped with 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 with the geometric center of the ink window area includes:

and adjusting the color value displayed by each pixel point of the display area to enable the geometric center of the preset image to be overlapped with the geometric center of the ink window area.

Specifically, adjusting the color value displayed by each pixel point of the display area to overlap the geometric center of the preset image with the geometric center of the ink window area means that when the preset image is displayed on the display screen, adjusting the distance of the offset size of the preset image in the direction opposite to the offset direction according to the offset direction and the offset size of the offset of the preset image relative to the ink window area, correspondingly, after the position of the preset image when displayed on the display screen is adjusted, the color value of the pixel point on the display screen is correspondingly adjusted, correspondingly adjusting the color value of each pixel point in the preset image to ensure that when the preset image is displayed on the display screen, and the geometric center of the preset image is overlapped with 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, the color value of the image pixel point of the preset image is displayed through the pixel point of the display screen. For example, referring to table 1, assume that the preset image includes 4 pixels, and each pixel corresponds to a corresponding color value, such as: in the preset image, the color value of the pixel at the position a11 is a1, the color value of the pixel at the position a12 is a2, the color value of the pixel at the position a13 is A3, the color value of the pixel at the position a14 is a4, and the pixel color values a1, a2, A3, a4 and the corresponding positional relationships thereof constitute the preset image.

Table 1

With reference to fig. 4, it is assumed 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 a first display area 2112, the first display area includes pixel points b11, b12, b13 and b14, and the correspondence between the pixel points of the first display area 2112 and the preset image is shown in table 1.

Suppose that, in the process of attaching the cover plate 200 of the display module to 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 region 212, the ink layer 220 is shifted by a distance d from the non-pixel region 212, the positions of the ink window region 2204 and the transparent portion 202 on the display screen are correspondingly shifted by the distance d, and a part of pixels of the size d of the first display region 2112 of the display screen are shielded by the inner edge of the ink layer 220, so that the pixels of the display screen, which can display images through the ink window region 2204 and the transparent portion 202, are shifted to the second display region 2112'.

If the position of the preset image when the display screen is displayed is set in the first display area 2112 before the cover plate 200 of the display module is attached to the display screen 210, when the preset image is displayed through the first display area 2112, the part of the preset image displayed by the size d part of the first display area 2112 is shielded by the ink layer 220 and cannot be displayed on the cover plate 200 through the ink window area 2204 and the transparent part 202, the electronic device acquires the first image, judges that the preset image is shifted relative to the ink window area of the display module when the preset image is displayed in the first display area 2112 of the display screen by analyzing the acquired first image, analyzes that the shift direction and the shift size of the preset image relative to the ink window area when the preset image is displayed in the first display area 2112 are d through the first image, and generating a correction instruction according to the offset direction and the offset size d, wherein the correction instruction is used for instructing the electronic device to move the position of the preset image when the preset image is displayed on the display screen from the first display region 2112 to the second display region 2112 ', and the electronic device moves the position of the preset image from the first display region 2112 to the second display region 2112 ' according to the received correction instruction, namely, the color value displayed by each pixel point of the second display region 2112 ' is adjusted to the color value of each pixel point of the preset image, so that when the preset image is displayed on the display screen, the geometric center of the preset image at the position of the display screen is overlapped with the geometric center of the ink window region.

and controlling a first preset pixel on one side of the preset image, which is offset relative to an ink window area of the display module, to be in a turn-off state and controlling a second preset pixel on the other side, which corresponds to the offset side, to be in a turn-on state according to the correction instruction, wherein the numerical value of the pixel column of the first preset pixel is the same as that of the pixel column of the second preset pixel, or the numerical value of the pixel row of the first preset pixel is the same as that 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, judges that the preset image deviates from the ink window area of the display module according to the first image, obtains the deviation direction and the deviation size of the preset image deviating from the ink window area through the first image, generates a correction instruction, controls a first preset pixel on one side of the preset image deviating from the ink window area to be in a blanking state and controls a second preset pixel on the other side corresponding to the one side of the preset image to be in a bright state according to the correction instruction when the display screen is in the bright screen state, wherein the numerical value of the pixel column of the first preset pixel is the same as the numerical value of the pixel column of the second preset pixel, or the numerical value of the pixel row of the first preset pixel is the same as the numerical value of the pixel row of the second preset pixel.

For example, it is assumed that a pixel area of a display panel is 100 × 100 pixels, and pixels of a display area of the display panel for displaying a preset image are 80 × 80 pixels, that is, a preset image of 80 × 80 pixels is displayed through the display area of the display panel. In general, the center line of the display region and the center line of the pixel region are overlapped, for example, to display a solid square with a size of 80 × 80 pixels in the display region, 10 rows of pixels on four sides of the pixel region are not lighted in the outward and inward direction, 80 pixels on the center region except for 10 rows of pixels on the four sides of the pixel region are lighted, if the position of the display region where the square is located is shifted to one side by 5 columns of pixels in the horizontal direction, only one side 5 columns of the pixel region need to be controlled not to be lighted, the other side 15 columns of the pixels corresponding to the one side are not lighted, and the rest columns of pixels are all lighted, so that the image effect is that the square is shifted to the one side by 5 columns of pixels.

Further, referring to fig. 2, if the electronic device determines that the preset image is shifted by two rows of pixels towards 2212 side relative to the ink window area of the display module according to the first image, the electronic equipment generates a correction instruction, the electronic equipment moves the position of the preset image when displayed on the display screen from the 2212 side to the corresponding 2213 side by the distance of two columns of pixels according to the correction instruction, the electronic equipment controls the position of the lighted pixels of the pixel area of the display screen to move from the 2212 side to the corresponding 2213 side by two columns of pixels in the horizontal direction through the display screen IC chip of the display module, namely when the display screen is lighted, the electronics control the two columns of pixels on the 2212 side near the pixel area boundary to be in a blanking state, the pixels in the two columns on the 2213 side are controlled to be in a lighting state by moving in the horizontal direction in sequence. Assuming that before the position of the preset image is moved when displayed on the display screen, 1 to 10 columns of pixels on the 2212 side and the 2213 side are not lighted according to the direction from the outside to the inside of the pixel area, after the position of the preset image is moved when displayed on the display screen, 1 to 12 columns of pixels on the 2212 side are not lighted according to the direction from the outside to the inside of the pixel area, and 1 to 8 columns of pixels on the 2213 side are not lighted, so that the preset image is centered in the ink window area of the cover plate when displayed on the display screen.
