[0002] In the field of display technology, liquid crystal display (LCD) modules are a widely used technology. However, in practical applications, display modules may exhibit anomalies, such as image retention, uneven brightness, or pixel failure. These problems may be caused by factors such as the display driver circuit, the pixels themselves, or foreign objects within the display module. Therefore, during repair, it is necessary to reproduce the display module's anomalies to find the root cause of the problem. However, currently, diagnosing display module anomaly problems usually requires manual power-on and power-off cycles to visually determine whether the anomaly is reproduced, which is time-consuming, labor-intensive, and prone to subjective judgment bias.

[0021] Step S13: Adjust the number of sub-region settings to the initial value, and determine whether the abnormal display position area is the maximum area.

These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0056] Example 1

[0057] like Figure 1 As shown, a method for automatically reproducing abnormal display of a display module upon power-on / off is disclosed, including the following steps:

[0058] Step S1: Acquire an image of the normally displayed image of the display module as a reference image, and define the abnormal display location area within the reference image. Specifically, the definition of the abnormal display location area is set by parameters input by a technician from an input device (such as a keyboard or mouse). The technician initially defines the abnormal display area based on what they see or what the user describes. More specifically, an image of the normally displayed image of the display module can be captured by a CCD camera or CMOS sensor as the reference image.

[0059] Step S2: Set the upper and lower limits of the brightness of the abnormal display area based on the brightness of the reference image. Specifically, in this invention, the brightness is characterized by calculating the average gray value of the abnormal display area in the image. The upper and lower limits of the brightness of the abnormal display area can be set according to requirements or based on the experience of technicians. For example, the upper limit of the brightness of the abnormal display area is 101% to 105% of the brightness of the abnormal display area, and the lower limit of the brightness of the abnormal display area is 95% to 99% of the brightness of the abnormal display area. This invention does not impose specific limitations.

[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 can be obtained by capturing the current screen image of the display module through a CCD camera or CMOS.

[0061] Step S4: Calculate the current brightness value of the region in the current image that is not clearly visible;

[0062] Step S5: Determine whether the current brightness value of the abnormal display location area exceeds the upper limit or lower limit of the brightness of the abnormal display location area. If yes, continue to power on the display module, issue an abnormal display notification, and end; otherwise, control the display module to power off and repeat steps S3-S5.

[0063] The present invention provides a method for automatically reproducing abnormal display module displays by powering on and off. Each time the display module is powered on, the current brightness value of the abnormal display area in the current image is calculated. It then determines whether the current brightness value of the abnormal display area exceeds the upper or lower limit of the brightness value for that area. If so, an abnormal display is detected, power is maintained on the display module, and a notification is sent to the technician. If not, the above operation continues until the abnormal display reappears. This achieves automatic detection of abnormal display modules, reducing the need for manual intervention and improving the stability and reliability of detection and reproduction. Once an abnormal display is detected, the power-off process is automatically stopped, maintaining the abnormal state of the module, thus facilitating researchers to identify the source of the problem. It is worth noting that this invention detects abnormalities in the display module by comparing brightness, and can detect abnormal displays caused by factors such as voltage abnormalities or display signal abnormalities, thus broadening its practical application.

[0064] Example 2

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

[0066] Step S6: Count the number of the first loop, which is the number of times steps S3-S5 have been executed in a loop;

[0067] Step S7: Determine if the number of the first loop exceeds the first preset value. If not, continue to 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: Divide the abnormal display location area evenly into several sub-regions, and set the upper and lower limits of brightness for each sub-region according to the reference image. For example, in some specific embodiments, the abnormal display location area is square, and the abnormal display location area is divided into multiple directional sub-regions. Of course, in other embodiments, the abnormal display location area is square, and the abnormal display location area is divided into multiple directional sub-regions. More specifically, the initial value of the number of sub-regions can be 2, 3, or 4, etc., and the present invention does not impose specific limitations.

[0069] Step S9: Control the display module to power on again, obtain the current screen image of the display module, and calculate the current brightness value of each sub-region in the different display position area in the current screen image;

[0070] Step S10: Determine whether the current brightness value of any sub-region exceeds the upper or lower limit of the corresponding sub-region's brightness. If yes, maintain power on the display module, issue an abnormal display notification, and end the process. If no, power off the display module and repeat steps S9-S10.

[0071] Because the initially defined abnormal display location area can be too large, while the actual abnormal display point area is small, even if the abnormal display reappears, the brightness change in the abnormal display location area is not significant, making it impossible to identify and detect. To solve this technical problem, in this embodiment, if the abnormal display is not detected after the first cycle exceeds a first preset value, the abnormal display location area is divided into multiple sub-regions. The display module is powered on again, and the current brightness value of each sub-region in the current image is calculated. It is determined whether the current brightness value of any sub-region exceeds the upper or lower limit of the corresponding sub-region's brightness. If so, the display module is kept powered on, and an abnormal display notification is issued. By dividing the area into several sub-regions for brightness comparison, the technical problem of the initially defined abnormal display location area being too large and the actual abnormal display point area being 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 repeatedly executing steps S9-S10, the following steps are also performed:

[0074] Step S11: Count the number of second loops. The number of second loops is the number of times steps S9-S10 have been executed. For every K increases in the number of second loops, the number of sub-regions increases by i. Specifically, the values ​​of K and i can be set according to actual needs; for example, the value of K ranges from 20 to 50, and the value of i ranges from 1 to 2. In some specific embodiments, the number of sub-regions in the abnormal display location area increases by 1 whenever the number of second loops increases by 30. In this embodiment, as the number of second loops increases, the number of sub-regions increases, further dividing the area into sub-regions and improving detection accuracy.

[0075] Example 4

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

[0077] Step S12: Determine if the second loop count exceeds the second preset value. If not, execute steps S9-S10 repeatedly. If so, stop executing 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-region settings to the initial value, and determine whether the abnormal display position area is the maximum area. If yes, issue a notification to readjust the abnormal display position area and end; otherwise, expand each edge of the abnormal display position area outward by N pixels, reset the first loop count and the second loop count to zero, and return to step S2.

[0079] In this embodiment, if the number of times steps S9-S10 have been executed exceeds the second preset value, it indicates that the abnormal display may not be within the previously defined abnormal display location area. Each edge of the abnormal display location area is expanded outward by N pixels to increase the size of the abnormal display location area. Then, the process returns to step S2, and automatic power-on / off detection is performed using the enlarged abnormal display location area. When the abnormal display location area has increased to its maximum size, a notification to readjust the abnormal display location area is issued to inform the technician that readjustment is necessary. Specifically, the maximum area can be set according to actual needs, for example, the maximum area can be 1.5 times, 2 times, etc., of the initial abnormal display location area. The outward expansion of each edge of the abnormal display location area can be 5 to 20 pixels, etc., depending on actual requirements.

[0080] A second aspect of the present invention discloses a system for automatically reproducing abnormal display of a display module upon power-on / off, used to perform the steps of the above-described method for automatically reproducing abnormal display of a display module upon power-on / off, the system comprising:
