This can lead to compensation errors and PIN misses (pin connection errors), resulting in poor display quality on the final display panel. Therefore, it is particularly important to promptly check the display panel for PIN misses after compensation. Summary of the Invention

[0049] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0050] It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and the accompanying drawings are used to distinguish similar items and are not necessarily used to describe a particular order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0051] Figure 1 FIG. 1 is a flow chart of a method for detecting display panel brightness compensation errors proposed in an embodiment of the present invention. Figure 1 As shown, the detection method comprises the following steps:

[0052] S101, obtaining a compensation file of at least one compensated display panel;

[0053] It is understood that during the display panel compensation process, when the compensation device compensates the display panel, it records the compensation parameters for the display panel and generates a compensation file for storage within the compensation device. During storage, each compensated display panel may be numbered or assigned a corresponding ID. During the detection method process, it is necessary to obtain this compensation file. This can be done by retrieving it by number or ID, or by requesting the corresponding number or ID through communication, or other methods, which are not specifically limited in the present invention.

[0054] S102, extracting the compensated parameters of each pixel point according to at least one compensation file;

[0055] After obtaining the compensation file in step S101, the compensated parameters in the compensation file are extracted. Each pixel includes at least one red pixel, at least one blue pixel, and at least one green pixel; the compensation file includes the coordinates and compensation voltage parameters of each red pixel, the coordinates and compensation voltage parameters of each blue pixel, and the coordinates and compensation voltage parameters of each green pixel in the same column.

[0056] For example, a display panel includes K rows and L columns of pixels, and each pixel includes a red pixel, a blue pixel, and a green pixel. Then, along the row direction, red, green, blue, red, green, blue, etc., are arranged one pixel at a time. Then, along the column direction, red, red, red, green, green, green, blue, etc., or green, green, green, green, green, blue, etc., are arranged in sequence. At the same row coordinate, after voltage compensation is performed on the red pixels in the same column, the row coordinates of each column, the corresponding row coordinates of the column, and the compensated voltage parameters corresponding to each red pixel in the column are recorded in the compensation file. Similarly, at the same row coordinate, after voltage compensation is performed on the green pixels in the same column, the row coordinates of each column, the corresponding row coordinates of the column, and the compensated voltage parameters corresponding to each green pixel in the column are recorded in the compensation file. Similarly, at the same row coordinate, after voltage compensation is performed on the blue pixels in the same column, the row coordinates of each column, the corresponding row coordinates of the column, and the compensated voltage parameters corresponding to each blue pixel in the column are recorded in the compensation file.

[0057] When each pixel includes two or more red pixels, two or more blue pixels, and two or more green pixels, reference may be made to the aforementioned examples.

[0058] S103, calculating an average value of the compensated parameters of each pixel in the same column of at least one compensated display panel;

[0059] Still using the previous example of step S102 for explanation, after extracting the compensated parameters, coordinates, etc. of each pixel point in the compensated display panel through step S102, the compensated voltage parameters of the red pixel points, or green pixel points, or blue pixel points in the same column can be summed and averaged.

[0060] S104, determining whether the difference between the average value and the preset average value is within a threshold range, if so, then the pixels in the same column are not compensated for errors; if not, then the pixels in the same column are compensated for errors.

[0061] It is understandable that, since the required voltages corresponding to the luminous brightness of red pixels, green pixels, and blue pixels are different, the requirements for the voltage parameters for compensation of red pixels, green pixels, and blue pixels are all different. However, the brightness of each red pixel in the same column of pixels should be the same after compensation, the brightness of each green pixel in the same column of pixels should be the same after compensation, and the brightness of each blue pixel in the same column of pixels should be the same after compensation. Therefore, the average value of the compensated voltage parameters of the pixels in the same column should be the same as the preset average value, or fluctuate within a certain range above and below the preset average value (the preset average value is the voltage parameter for the pixels in the column to achieve the same luminous brightness).

[0062] If the average value is greater than the preset average value and the difference between the two is greater than the threshold range, or is less than the preset average value and the difference between the two is greater than the threshold range, it means that the compensation of this column of pixels is incorrect, which means that the pins on the display panel corresponding to this column of pixels and the pin connections of the compensation device are intertwined and need to be checked and corrected.

[0063] In other embodiments, it is possible to simply determine that the average value is less than the preset average value and the difference between the two is greater than the threshold range, which indicates that the compensation of the pixel column is incorrect. Because a certain column of pixels is darker, obvious black lines will appear on the display panel, while brighter pixels will not have obvious bright lines. Furthermore, in order to save computing costs, it is possible not to determine that the average value is greater than the preset average value and the difference between the two is greater than the threshold range.

[0064] Therefore, by obtaining the compensation file and extracting the compensation parameters in the compensation file, it can be determined whether the pins between the display panel and the compensation device are misconnected, so that when misconnection occurs, the staff can correct the pin overlap in time.

[0065] According to one embodiment of the present invention, Figure 2 As shown, S101 obtaining a compensation file of at least one compensated display panel includes:

[0066] S1011, obtaining compensation files of a plurality of consecutive compensated display panels;

[0067] S102, extracting the compensated parameters of each pixel point according to at least one compensation file, includes:

[0068] S1021, extracting the compensated parameters of each pixel point in the multiple compensation files respectively;

[0069] S103, calculating an average value of the compensated parameters of each pixel point in the same column of at least one compensated display panel includes:

[0070] S1031, calculating an average value of the compensated parameters of each pixel point in the same column of a plurality of compensated display panels;

[0071] S1041, if the difference between the average value of the compensated parameters of each pixel point under the i-th column in the n-th compensation display panel and the preset average value is not within the threshold range, and the difference between the average value of the compensated parameters of each pixel point under the j-th column in the (n+1)-th compensation display panel and the preset average value is not within the threshold range, then the compensation of each pixel point is incorrect, where i, j, n are positive integers, i≤m, j≤m.

[0072] According to one embodiment of the present invention, i=j.

[0073] It is understood that in this embodiment, "multiple" means at least two. For example, compensation files for two consecutive compensated display panels are obtained, and each compensation file can be used to obtain the average value of the compensated parameters of each pixel point in the same column of the corresponding compensated display panel. Taking the first compensated display panel and the second compensated display panel as an example, if the average value of the fifth column of the first compensated display panel is less than the preset average value and the difference between the average value and the preset average value is greater than a threshold range, and the average value of the eighth column of the second compensated display panel is less than the preset average value and the difference between the average value and the preset average value is greater than a threshold range; or if the average value of the fifth column of the first compensated display panel is less than the preset average value and the difference between the average value and the preset average value is greater than a threshold range, and the average value of the fifth column of the second compensated display panel is less than the preset average value and the difference between the average value and the preset average value is greater than a threshold range, then it is determined that the pins between the first compensated display panel and the second compensated display panel and the compensation device are misconnected. That is, if the average value of the two consecutive compensated display panels is less than the preset average value and the difference between the average value and the preset average value is greater than a threshold range, it is determined that the pins between the display panel and the compensation device are misconnected.

[0074] In other embodiments, in order to avoid errors in detection, the number of multiple items can also be three, four, etc., that is, when three or four consecutive compensated display panels are detected and the average value is found to be less than the preset average value and the difference between the average value and the preset average value is greater than the threshold range, it is determined that the pins between the display panel and the compensation device are misconnected.

[0075] It should be noted that i and j can be the same (for higher accuracy) or different (to improve detection sensitivity). When i and j are different, i ≤ m and j ≤ m. The distance between i and j is m columns, and m can optionally be 800. That is, within 800 columns, if the average value of any column between columns 0-800 of a plurality of consecutive compensated display panels is less than a preset average value and the difference is greater than a threshold range, it can be determined that the pins between the plurality of compensated display panels and the compensation device are misconnected.

[0076] The distance m between the corresponding i and j can be determined by the coordinate positions recorded in the compensation file. Therefore, the coordinate positions can be used to determine which part of the pins in the display panel and the compensation device are incorrectly overlapped.

[0077] In this way, it is avoided that the compensation error of the display panel is discovered during the subsequent inspection process. The detection method proposed in the embodiment of the present invention can detect after compensation, and the compensation error can be discovered in time to adjust the pin overlap between the compensation device and the next compensated display panel.

[0078] Figure 3 FIG is a block diagram of a device for detecting display panel brightness compensation errors according to an embodiment of the present invention. Figure 3As shown, the detection device 100 includes:

[0079] An acquisition module 101 is configured to acquire a compensation file of at least one compensated display panel;

[0080] An extraction module 102 is configured to extract compensated parameters of each pixel point according to at least one compensation file;

[0081] A calculation module 103, configured to calculate an average value of the compensated parameters of the pixels in the same column of at least one compensated display panel;

[0082] The judgment module 104 is used to judge whether the difference between the average value and the preset average value is within a threshold range. If so, the pixels in the same column have not been compensated for errors; if not, the pixels in the same column have been compensated for errors.

[0083] According to one embodiment of the present invention, Figure 4 Shown, including:

[0084] The acquisition module 101 includes:

[0085] An acquisition submodule 1011 is configured to acquire compensation files of a plurality of consecutive compensated display panels;

[0086] The extraction module 102 includes:

[0087] The extraction submodule 1021 is used to extract the compensated parameters of each pixel point in the multiple compensation files respectively;

[0088] The calculation module 103 includes:

[0089] A calculation submodule 1031 is configured to calculate an average value of the compensated parameters of the pixels in the same column of the plurality of compensated display panels;

[0090] The judgment module 104 is further configured to determine that compensation of each pixel point is incorrect if the difference between the average value of the compensated parameters of each pixel point in the i-th column of the n-th compensation display panel and the preset average value is not within a threshold range, and the difference between the average value of the compensated parameters of each pixel point in the j-th column of the n+1-th compensation display panel and the preset average value is not within a threshold range, where i, j, and n are positive integers, i≤m, j≤m.

[0091] According to one embodiment of the present invention, i=j.

[0092] Please refer to the method examples for the above parts, which will not be described in detail here.

[0093] According to one embodiment of the present invention, Figure 5 As shown, it also includes: a display module 105 and a control module 106;

[0094] The control module 106 is connected to the judgment module 104 and the display module 105 respectively. The control module 106 is used to control the display module 105 to display the corresponding result according to the judgment result of the judgment module 104.

[0095] For example, the display module 105 can be a display that includes multiple continuous display color blocks, where one color block represents m columns, for example, m is 800. That is, if two consecutive compensated display panels have a compensation error in one of the same 0-800 columns of pixels, then the color block corresponding to the 0-800 columns of pixels will display red. Conversely, if the compensation is normal, it will display green. The number of color blocks is determined by the total number of pixel rows or total number of pixel columns of the compensated display panel. Therefore, through the setting of the display module 105, it is possible to intuitively remind the staff which part of the pin overlap of the compensation device has a problem.

[0112] In summary, according to the method, apparatus, device, and medium for detecting display panel brightness compensation errors proposed in the embodiments of the present invention, first, a compensation file for at least one compensated display panel is obtained; then, the compensated parameters of each pixel are extracted based on the at least one compensation file; then, the average value of the compensated parameters of each pixel in the same column of at least one compensated display panel is calculated; finally, a determination is made as to whether the difference between the average value and a preset average value is within a threshold range. If so, the pixels in the same column have not been compensated for errors; if not, the pixels in the same column have been compensated for errors. Thus, the relevant compensated parameters can be extracted from the compensation file after compensation, and finally, the difference between the average value of the compensated parameters and the preset average value is used to determine whether a compensation error has occurred. If a compensation error has occurred, it is determined that a PIN miss has occurred, thereby promptly checking and correcting the connection pins between the display panel and the compensation device.
