[0033] The implementation details of the technical solutions of the embodiments of this disclosure are described in detail below.

[0034] Figure 1 This schematically illustrates a flowchart of a display area testing method according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the display area testing method includes steps S101 to S105:

[0035] Step S101: Based on the resolution of the display screen, a virtual test area is obtained, which is composed of the maximum width and the maximum height; wherein, the virtual test area includes a horizontal axis and a vertical axis;

[0036] Step S102: Generate a first test image including a first test graphic based on the maximum width and a preset test value; and generate a second test image including a second test graphic based on the maximum height and the test value.

[0037] Step S103: Traverse the first test graphic along the vertical axis to obtain the first display image corresponding to each vertical coordinate, and traverse the second test graphic along the horizontal axis to obtain the second display image corresponding to each horizontal coordinate.

[0038] Step S104: Match the first test image with each of the first display images to obtain a first safe display pixel, and match the second test image with each of the second display images to obtain a second safe display pixel;

[0039] Step S105: Take the union of the first security display pixel and the second security display pixel as the security display area of ​​the display screen.

[0040] In some embodiments of this disclosure, the maximum width and maximum height are first determined based on the display screen's resolution, and a virtual test area with the maximum width and maximum height is constructed. Then, test graphics and test images are generated based on preset test values ​​along the horizontal or vertical axis of the virtual test area. The test image is then moved through the virtual test area to obtain a display image. Finally, the test image and the display image are matched to obtain a secure display area composed of a certain number of displayable pixels. Based on this method, non-secure display areas such as rounded corners and cameras can be excluded, and a secure display area at the pixel level ensuring a certain number of displayable pixels can be obtained from the tests of various devices' displays. This secure display area can then be used for information display, improving the completeness of the information display.

[0041] The following will describe in more detail each step of the display area testing method in this exemplary embodiment, with reference to the accompanying drawings and embodiments.

[0042] In step S101, a virtual test area is obtained based on the resolution of the display screen, consisting of the maximum width and the maximum height; wherein the virtual test area includes a horizontal axis and a vertical axis.

[0043] Specifically, since different displays may have different resolutions, in order to obtain a pixel-level safe display area, the maximum width W and maximum height H of the display can be obtained based on the resolution.

[0044] In one embodiment of this disclosure, the width of the display screen can be used as the horizontal axis and the height as the vertical axis. The coordinates of the pixels on the display screen then lie within a rectangular area of ​​a virtual test region with a width of W and a height of H. Considering the actual display effect, the actual coordinates of the pixels on the display screen are located between (0,0) and (H-1, W-1) or between (1,1) and (H, W).

[0045] It should be noted that the virtual test area is only constructed based on the maximum width and height. The pixels corresponding to the pixels in the virtual test area may not necessarily be displayed on the screen. For example, the camera area and the rounded corners around the device may be located within the virtual test area, but their display is not guaranteed. Therefore, the ultimate goal of this method is to test and identify a guaranteed displayable safe area from the virtual test area.

[0046] The horizontal and vertical axes are merely illustrative examples, and those skilled in the art should understand that they can be interchanged in practical applications.

[0047] In step S102, a first test image including a first test graphic is generated based on the maximum width and a preset test value, and a second test image including a second test graphic is generated based on the maximum height and the test value.

[0048] It should be noted that the steps for generating the first test image and the second test image are similar, the only difference being that they are performed along the two coordinate axes of the virtual test area. Therefore, the process of generating the first test image and the first test graphic will be described in detail below. It is conceivable that by interchanged coordinate axes, the same steps can be used to obtain the second test image and the second test graphic.

[0049] Specifically, step S102, which generates the first test image, includes the following steps:

[0050] 1) Draw the first test line segment along the horizontal axis based on the maximum width;

[0051] 2) Draw a second test line segment and a third test line segment that start from the endpoints of the first test line segment and are perpendicular to the first test line segment along the positive direction of the vertical axis, and a fourth test line segment and a fifth test line segment that are perpendicular to the first test line segment along the opposite direction of the vertical axis, based on the test values.

[0052] 3) The first test line segment, the second test line segment and the third test line segment are combined to obtain the first upper test pattern, and the first test line segment, the fourth test line segment and the fifth test line segment are combined to obtain the first lower test pattern.

[0053] Specifically, firstly, a line segment with a length equal to the maximum width W is drawn along the width direction of the display screen as the first test line segment L1. The two segments of the line segment are A(0,i) and B(W-1,i), where i is any vertical coordinate value.

[0054] With the test value set to k, along the positive vertical axis, draw a second test line segment L2 starting from A(0,i) and extending from (0,i) to (0,i+k) with a length of k, and draw a third test line segment L3 starting from B(W-1,i) and extending from (W-1,i) to (W-1,i+k) with a length of k. Along the negative vertical axis, draw a fourth test line segment L4 starting from A(0,i) and extending from (0,i) to (0,ik) with a length of k, and draw a fifth test line segment L5 starting from B(W-1,i) and extending from (W-1,i) to (W-1,ik) with a length of k.

[0055] Figure 2 This schematic diagram illustrates a first upper test pattern in an exemplary embodiment of the present disclosure. L1, L2, and L3 are combined to obtain the first upper test pattern U1, as shown below. Figure 2 As shown, the opening of the first upper test pattern faces upwards; Figure 3 This schematic diagram illustrates a first test pattern in an exemplary embodiment of the present disclosure. L1, L4, and L5 are combined to obtain the first test pattern, as shown below. Figure 3 As shown, the opening of the first test pattern U2 faces downwards.

[0056] After obtaining the test graphic, a test image is generated, including a first upper test image and a first lower test image, for subsequent image matching with the display image.

[0057] The process of generating a second test image including a second test pattern based on the maximum height and the test value is similar to that of generating a first test image including a first test pattern, or the horizontal axis and the vertical axis are swapped to obtain a second test pattern including a second right test pattern U3 with the opening facing right and a second left test pattern U4 with the opening facing left.

[0058] Specifically, draw the sixth test line segment L6 along the vertical axis based on the maximum height; draw the seventh test line segment L7 and the eighth test line segment L8, which are perpendicular to the sixth test line segment in the positive direction of the horizontal axis, starting from the endpoints of the sixth test line segment, and the ninth test line segment L9 and the tenth test line segment L10, which are perpendicular to the sixth test line segment in the opposite direction of the horizontal axis, based on the test values.

[0059] In step S103, the first test graphic is traversed along the vertical axis to obtain the first display image corresponding to each vertical coordinate, and the second test graphic is traversed along the horizontal axis to obtain the second display image corresponding to each horizontal coordinate.

[0060] Specifically, step S103, which generates the first display image, includes the following steps:

[0061] 1) Determine a target ordinate i based on the virtual test area;

[0062] 2) Record the display effects of the first upper test image and the first lower test image, where the vertical coordinate of the first test line segment is the target vertical coordinate, displayed on the display screen respectively, so as to obtain the first upper display image P corresponding to the target vertical coordinate i. i,1 And the first image P is displayed i,2 ;

[0063] 3) Repeat the above steps of determining the target ordinate and recording the display effect until the ordinate of the virtual test area has been traversed to obtain the first upper display image and the first lower display image corresponding to each ordinate.

[0064] Specifically, the process involves traversing the vertical coordinates of the first test line segment in the first test pattern to obtain the first display image corresponding to each vertical coordinate. Since the first test pattern includes an upper test pattern U1 with its opening facing upwards and a lower test pattern U2 with its opening facing downwards, a first upper display image P displaying U1 will be generated at each vertical coordinate. i,1 And display the first image P of U2. i,2 .

[0065] When recording the display effect, the screen first needs to display the test graphic at the target position according to the coordinate system. Line segments in the test graphic that are not within the range of the screen can be ignored. Then, take a picture to record the current image of the screen as the display image, and obtain the first upper display image of display U1 and the first lower display image of display U2.

[0066] During the traversal, the ordinate can be changed from 0 to H-1 or from H-1 back to 0, with a step size of 1 for each update. Since the W and H values ​​are obtained based on the display resolution, increasing the ordinate by 1 here actually corresponds to adding one pixel. After the traversal, the display image corresponding to each ordinate value in [0, H-1] is obtained.

[0067] Figure 4 This schematic diagram illustrates a first lower display image in an exemplary embodiment of the present disclosure, with reference to... Figure 4 As shown, the first test pattern is displayed on the screen to be tested. Figure 4 .

[0068] In one embodiment of this disclosure, the process of traversing the second test graphic along the horizontal axis to obtain the second display image corresponding to each horizontal coordinate is similar to generating the first display image, or the horizontal axis and vertical axis are swapped to obtain the second right display image and the second left display image of display U3 corresponding to each horizontal coordinate value.

[0069] That is, a target horizontal coordinate j is determined based on the virtual test area; the display effect of the first right test image and the first left test image, where the horizontal coordinate of the sixth test line segment is the target horizontal coordinate, is recorded on the display screen to obtain the first right display image P corresponding to the target horizontal coordinate j. j,1 And the first left-hand display image P j,2 Repeat the steps of determining the target x-coordinate and recording the display effect until the x-coordinate of the virtual test area has been traversed to obtain the first right display image and the first left display image corresponding to each x-coordinate.

[0070] In step S104, the first test image is matched with each of the first display images to obtain a first safe display pixel, and the second test image is matched with each of the second display images to obtain a second safe display pixel.

[0071] Specifically, the process of obtaining the first security display pixel in step S104 is as follows:

[0072] 1) For a target ordinate i, the first upper test image and the first lower test image are respectively matched with the first upper display image P corresponding to the target ordinate i. i,1 And the first image P is displayed i,2 By combining each pair, four matching pairs are obtained;

[0073] 2) When there is a matching pair among the four matching pairs where the first test graphic matches the first displayed image, the target ordinate is marked as the matching ordinate.

[0074] 3) Repeat the above matching steps until the vertical coordinates of the virtual test area have been traversed to obtain all the matching vertical coordinates, and obtain the first safe display pixel based on the matching vertical coordinates.

[0075] This process involves iterating through all ordinates, determining whether a given ordinate is a matching ordinate based on the image matching results, and finally obtaining the first safe display pixel based on the matching ordinate. Image matching is then used to match P. i,1 P i,2 Matching with U1 and U2 forms P i,1 -U1、P i,1 -U2、P i,2 -U1、P i,2 -U2 has four matching pairs. If there is one matching pair, then the ordinate i is recorded as the matching ordinate x. i Finally, the result is obtained by matching the ordinate y. i The Y-axis is formed by this. Similarly, those skilled in the art will readily conceive of obtaining the matching x-coordinate. i X constitutes the whole.

[0076] Therefore, in one embodiment of this disclosure, the method further includes: determining whether the first test graphic in the matching pair matches the first display image. Specifically, the steps are as follows: extracting the contour of the first display image in the matching pair to obtain a first display graphic; performing shape matching between the display graphic and the first test graphic to determine whether the first test graphic matches the first display image.

[0077] Specifically, the first step is to extract the contour of the first display image to obtain a display graphic composed of three line segments. Figure 5 This diagram schematically illustrates a contour extraction result in an exemplary embodiment of the present disclosure. Figure 4 Taking the first displayed image as an example, the result after contour extraction is referenced. Figure 5 As shown.

[0078] After contour extraction, the extracted display graphic is matched with the matching graphic. Graphic matching can be performed by changing the size of the display graphic, rotating it, or translating it. The advantage of using these methods is that when matching graphics or capturing images from the screen, there's no need to consider scale, translation, or rotation issues. For example, even if the captured image is too large or too small, or not perfectly aligned, it can still be matched more accurately.

[0079] In one embodiment of this disclosure, the method further includes: setting the background color of the display screen to a first color, and setting the color of the first test graphic to a second color; wherein the first color is different from the second color.

[0080] Specifically, since contour extraction is required for the first displayed image, the greater the color difference when the display screen shows the test pattern, the better the contour extraction effect. Therefore, the background color of the display screen and the color of the first test pattern can be set to a second color that is significantly different from the display image to improve the accuracy of contour extraction and further improve the accuracy of pattern matching.

[0081] Repeat the matching steps above, judge each ordinate, and finally obtain all the matching ordinates. Then, obtain the first safe display pixel based on the matching ordinates.

[0082] In one embodiment of this disclosure, obtaining the first safe display pixel based on the matching ordinate specifically includes the following steps: for a target matching ordinate, marking the pixel in the first test line segment of the first test graphic corresponding to the target matching ordinate as a safe display pixel; traversing all the matching ordinates to obtain all the safe display pixels.

[0083] Specifically, iterate through each item y in Y. i The first test line segment (0, y) i) to (W-1, y i All pixels in X are marked as the first safe display pixel. Similarly, traversing each item x in X... i The sixth test segment (x) i ,0) to (x i All pixels (H-1) are marked as second security display pixels.

[0084] In step S105, the union of the first security display pixel and the second security display pixel is taken to obtain the security display area of ​​the display screen.

[0085] Specifically, the union of the first and second security display pixels is taken to obtain all security display pixels, and the range formed by all security display pixels is the security display area of ​​the display screen.

[0086] The safe display area is the regular display area on the screen excluding areas such as cameras and rounded corners, ensuring that the image is always visible.
