[0054] In order to make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0055] The following specific embodiments describe in detail the technical solutions of the embodiments of the present application and how the technical solutions of the embodiments of the present application solve the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0056] Example 1

[0057] like Figure 1 As shown, a method for automatically powering on and off to reproduce abnormal display of a display module is disclosed, comprising the following steps:

[0058] Step S1: The image normally displayed by the display module is obtained as a reference image, and the abnormal display location area is framed within the reference image. Specifically, the abnormal display location area is set by parameters input by a technician using an input device (such as a keyboard or mouse). The technician preliminarily frames the abnormal display area by visually observing the abnormal display area, or by verbally describing the abnormal display area by the user. More specifically, the image normally displayed by the display module can be captured using a CCD camera or CMOS to serve as the reference image.

[0059] Step S2: setting the upper and lower limits of the brightness of the abnormal display position area according to the brightness of the reference screen image; specifically, in the present invention, the brightness is characterized by calculating the average grayscale value of the abnormal display position area in the image, and the upper and lower limits of the brightness of the abnormal display position area can be set according to demand, and can also be set according to the experience output of the technicians. For example, the range of the upper limit of the brightness of the abnormal display position area is 101% to 105% of the brightness of the abnormal display position area, and the range of the lower limit of the brightness of the abnormal display position area is 95% to 99% of the brightness of the abnormal display position area. The present invention does not impose specific restrictions.

[0060] Step S3: Control the display module to power on again and obtain the current screen image of the display module; the current screen image of the display module can be photographed by a CCD camera or CMOS to obtain the current screen image.

[0061] Step S4: Calculate the current brightness value of the abnormal display position area in the current screen image;

[0062] Step S5: Determine whether the current brightness value of the abnormal display position area exceeds the upper brightness limit value of the abnormal display position area or exceeds the lower brightness limit value of the abnormal display position area. If so, keep the display module powered on, issue an abnormal display notification, and end; if not, control the display module to power off, and loop through steps S3-S5.

[0063] The present invention provides a method for automatically powering on and off to reproduce abnormal display in a display module. The method automatically powers the display module on and off. Each time the power is turned on, the current brightness value of the abnormal display location area in the current screen image of the display module is calculated. A determination is made as to whether the current brightness value of the abnormal display location area exceeds the brightness upper limit or the brightness lower limit of the abnormal display location area. If so, it indicates that abnormal display has occurred, the display module remains powered on, and an abnormal display notification is issued to inform the technician of the abnormal display. If not, the above operation is repeated until the abnormal display reappears. This achieves automatic detection of abnormal display in the display module, reduces the need for manual intervention, and improves the stability and reliability of detection and reproduction. Once an abnormal display is detected, the power-off process is automatically stopped, maintaining the module in an abnormal state, thereby facilitating researchers to identify the source of the problem. It is worth noting that the present invention detects display module anomalies by comparing brightness, and can detect abnormal display caused by factors such as voltage anomalies and display signal anomalies, thus expanding its practical scope.

[0064] Example 2

[0065] like Figure 2 As shown, a preferred embodiment of the present invention further includes the following steps before cyclically executing steps S3-S5:

[0066] Step S6: Counting the first cycle number, where the first cycle number is the number of times steps S3 to S5 have been executed cyclically;

[0067] Step S7: Determine whether the first cycle number exceeds the first preset value. If not, execute steps S3-S5 in a loop; if so, stop executing steps S3-S5 in a loop and jump to step S8.

[0068] Step S8: Evenly divide the abnormal display position area into a plurality of sub-areas, and set the upper and lower brightness limits of each sub-area according to the reference screen image. For example, in some specific embodiments, the abnormal display position area is square, and the abnormal display position area is divided into a plurality of directional sub-areas. Of course, in other embodiments, the abnormal display position area is square, and the abnormal display position area is divided into a plurality of directional sub-areas. More specifically, the initial number of sub-areas can be 2, 3, 4, etc., and the present invention does not impose any specific limitation.

[0069] Step S9: controlling the display module to power on again, obtaining the current screen image of the display module, and calculating the current brightness value of each sub-area in the abnormal display position area in the current screen image;

[0070] Step S10: Determine whether the current brightness value of any sub-area exceeds the brightness upper limit or brightness lower limit of the corresponding sub-area. If so, keep the display module powered on, issue an abnormal display notification, and end; if not, control the display module to power off and loop through steps S9-S10.

[0071] Because the abnormal display position area framed in the early stage may be too large, while the actual area of ​​the abnormal display point is small, even if the abnormal display is reproduced, the brightness of the abnormal display position area does not change much, resulting in no way to identify and detect it. To solve this technical problem, in this embodiment, when the number of first cycles exceeds the first preset value and no abnormal display is detected, the abnormal display position area is divided into multiple sub-areas, the display module is controlled to be powered on again, the current brightness value of each sub-area in the abnormal display position area in the current screen image is calculated, and it is determined whether the current brightness value of a sub-area exceeds the brightness upper limit or brightness lower limit of the corresponding sub-area. If so, the display module is kept powered on and an abnormal display notification is issued. By dividing the area into several sub-areas for brightness comparison, the technical problem that the abnormal display position area framed in the early stage is too large and the actual abnormal display point area is too small to be detected is effectively solved.

[0072] Example 3

[0073] like Figure 3 As shown, in one embodiment of the present invention, before looping through steps S9-S10, the following steps are further performed:

[0074] Step S11: Count the number of second loops. The second loop number is the number of times steps S9-S10 have been executed cyclically. For every K increase in the second loop number, the number of sub-regions increases by i. Specifically, the K value and the i value can be set according to actual needs. For example, the K value range is 20-50; the i value range is 1-2. In some specific embodiments, every time the second loop number increases by 30 times, the number of sub-regions in the abnormal position area increases by 1. In this embodiment, when the second loop number increases, the number of sub-regions increases, thereby further dividing the sub-regions and improving detection accuracy.

[0075] Example 4

[0076] like Figure 4 As shown, in one embodiment of the present invention, before the steps S9-S10 are executed cyclically, the following steps are further included:

[0077] Step S12: Determine whether the second cycle number exceeds the second preset value. If not, loop through steps S9-S10; if so, stop looping through steps S9-S10 and jump to step S13. Specifically, the second preset value can be 150, 200, etc., which can be set according to actual needs.

[0078] Step S13: Adjust the number of sub-area settings to the initial value, and determine whether the abnormal display position area is the largest area. If so, issue a notification to readjust the abnormal display position area and end; if not, expand each edge of the abnormal display position area outward by N pixels, reset the first and second loop times to zero, and return to step S2.

[0079] In this embodiment, when the number of times steps S9-S10 have been cyclically executed exceeds the second preset value, it indicates that the abnormal display may not be within the abnormal display position area framed in the early stage. Each edge of the abnormal display position area is expanded outward by N pixels to increase the abnormal display position area. Then return to step S2 to perform automatic power on and off detection with the enlarged abnormal display position area. When the abnormal display position area has increased to the maximum area, a notice of readjustment of the abnormal display position area is issued to inform the technician that the abnormal display position area needs to be readjusted. Specifically, the maximum area can be set according to actual needs, for example, the maximum area is 1.5 times, 2 times, and so on, of the initial abnormal display position area. Among them, each edge of the abnormal display position area can be expanded outward by 5 to 20 pixels, etc., which can be set according to actual needs.
