The distance of each point on the boundary of the light-transmitting region 21 from the second center P has been obtained as the second distance, and as shown in fig. 6, point C is a point on the boundary of the light-transmitting region, and the second distance of point C from the second center P is l4The component displacement along the x-axis is l41The component along the y-axis is displaced by l42Therefore, the pixel coordinate of the pixel corresponding to the orthographic projection of the boundary point C of the light-transmitting area 21 in the pixel arrangement area 11 is
The pixel coordinates between the second center P and the boundary of the light-transmitting region 21 are the pixel coordinates in the display region 12. The pixel coordinates of the point corresponding to the boundary of the light-transmitting region 21 may be acquired first, and the pixel coordinates of the display region may be acquired in the region defined by the boundary.
Specifically, as shown in fig. 12, the step S2 of acquiring the first position, the second position, and the size of the boundary of the light-transmitting area includes:
step S21 of forming a mark pattern 13 in the pixel arrangement region 11; wherein, a feature point is formed on the mark pattern 13, and the feature point is the mark point O of the pixel arrangement area 11. The feature point and the mark point O are the same point, the mark pattern 13 may be a polygon, and a vertex of the polygon is located at the mark point O of the pixel arrangement area 11, where the vertex of the polygon is the feature point of the mark pattern 13. In addition, the mark pattern 13 may also be a central symmetrical pattern, where a feature point of the central symmetrical pattern is a symmetrical center of the central symmetrical pattern, and the symmetrical center is located on the mark point O of the pixel arrangement area 11, where the central symmetrical pattern may be a rectangle, a circle, or the like, and is not limited specifically herein.
Step S22, acquiring image information of the light emitting surface of the display module, where the image information of the mark pattern 13 and the image information of the light transmitting area 21 are formed in the image information; the driving pixel arrangement region 11 displays a mark pattern 13, and the CCD is used to obtain image information of the light-emitting surface of the display module, where the image information is specifically shown as 8.
Step S23, obtaining the size of the first position, the second position, and the boundary of the light-transmitting area according to the image information of the light-emitting surface of the display module. The image information records the position of the mark point O on the display module and the position of the light-transmitting area 21 on the display module. The size of the boundary of the light-transmitting area 21 and the position of the boundary of the light-transmitting area 21 on the display module can be obtained through the image information, and then a first distance between each point of the boundary of the light-transmitting area 21 and the mark point O and a second distance between each point of the boundary of the light-transmitting area 21 and the second center P can be obtained. In addition, the position of the second center P on the display module can be obtained according to the image information. When the image information of the light-emitting surface of the display module is acquired, the pixel arrangement area is used as the display area to display the mark pattern 13, the display area recorded in the driving IC of the display module is all the pixel coordinates in the pixel arrangement area 11, after the pixel coordinates of the display area 12 are determined, the pixel coordinates in the display area 12 are input to the driving IC, the driving IC automatically deletes the original register value, and the newly input pixel coordinate range of the display area 12 is used as the display area 12 to start displaying.
Specifically, the method further comprises the following steps: step S4, determining a first proportion of a first pixel in a first area, wherein the first area is covered by an orthogonal projection of the light-transmitting area on the pixel arrangement area, and the first pixel is a pixel located at an edge of the first area; when the first ratio exceeds the preset ratio, the first pixel is counted in the display area 12. Since the projection of the boundary of the light-transmitting region 21 in the pixel arrangement region 11 may be located in the space between two pixels and may also be located on the first pixel. That is, the edge of the first region may be located in the gap between two pixels or may be located on the first pixel. When the edge of the first region is located in the gap between two pixels, that is, all the first pixels located at the edge of the first region are located in the first region, then all the first pixels are included in the display region 12. When the edge of the first region is located on the first pixel, the edge of the first region divides the first pixel into two parts, one part is located in the first region, and the other part is located outside the first region, at this time, a first ratio of the part located in the first region to the first pixel needs to be calculated, if the first ratio is greater than or equal to 50%, the first pixel is counted into the display region 12, at this time, if the first ratio does not exceed 50%, the first pixel is not counted into the display region 12, and the preset ratio may be set to other values. Since the edge of the light-transmitting area 21 may be located on the first pixel to divide the first pixel into two parts, when the first pixel is counted into the display area 12, the edge of the display area 12 is located in the orthographic projection of the shielding area 22, but since the first pixel is small, the viewing effect of the user is hardly affected, and when the first pixel is counted into no display area 12, the boundary of the display area 12 is located in the area covered by the orthographic projection of the light-transmitting area 21, so that a small gap is formed between the boundary of the display area 12 and the boundary of the light-transmitting area 21, and the value of the gap does not exceed the size of one pixel, so that the gap is not observed by the user. Here, the preset ratio may be any value other than 0% from 0% to 100%, that is, the preset ratio may be 30%, 70%, 100%, and the like, and is not particularly limited herein.
