Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions.
FIG. 1 is a flowchart illustrating a method for detecting a display panel luminance compensation error according to an embodiment of the present invention. As shown in fig. 1, the detection method includes the following steps:
s101, obtaining a compensation file of at least one compensated display panel;
it can be understood that, in the compensation process for the display panel, when the compensation device compensates the display panel, the compensation device records the parameters compensated for the display panel and generates a compensation file to be stored in the compensation device, and when the compensation file is stored, each compensated display panel can be numbered or a corresponding ID can be generated. In the flow of the detection method, the compensation file needs to be acquired, and the acquisition mode may be called by a number or an ID, or by other acquisition modes such as a corresponding number of a communication request or ID acquisition, which is not particularly limited in the present invention.
S102, extracting compensated parameters of each pixel point according to at least one compensation file;
after the compensation file is acquired through step S101, the compensated parameters in the compensation file are extracted. Each pixel point comprises at least one red pixel point, at least one blue pixel point and at least one green pixel point; the compensation file comprises coordinates and compensation voltage parameters of each red pixel point, coordinates and compensation voltage parameters of each blue pixel point, and coordinates and compensation voltage parameters of each green pixel point in the same column.
For example, the display panel includes K rows and L columns of pixels, each pixel includes a red pixel, a blue pixel and a green pixel, and red, green and blue pixels are arranged along the row direction, and one pixel is arranged along the column direction, and red, red and red, or green, and green, or blue, and blue. And under the same row coordinate, after voltage compensation is carried out on the red pixel points in the same column, the row coordinate of each column, each row coordinate corresponding to the column and the compensated voltage parameter corresponding to each red pixel point in the column are recorded in the compensation file. Similarly, after voltage compensation is performed on green pixels in the same row under the same row coordinate, the row coordinate of each row, each row coordinate corresponding to the row, and a compensated voltage parameter corresponding to each green pixel in the row are recorded in the compensation file. Similarly, after voltage compensation is performed on blue pixels in the same column under the same row coordinate, the row coordinate of each column, each row coordinate corresponding to the column, and a compensated voltage parameter corresponding to each blue pixel in the column are recorded in the compensation file.
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 foregoing example.
S103, calculating the average value of the compensated parameters of all pixel points in the same column in at least one compensated display panel;
still taking the previous example of step S102 for explanation, after extracting the compensated parameters, coordinates, and the like of each pixel in the compensated display panel through step S102, the compensated voltage parameters of the red pixels, or the green pixels, or the blue pixels in the same row may be added and averaged.
S104, judging whether the difference value of the average value and a preset average value is within a threshold range, if so, not compensating errors of all pixel points in the same row; if not, the compensation error of each pixel point in the same column is carried out.
It can be understood that, because the required voltages corresponding to the luminance of the red pixel points, the green pixel points and the blue pixel points are different, the requirements on the voltage parameters compensated by the red pixel points, the green pixel points and the blue pixel points are different. However, the brightness of each red pixel in the same row of pixels after compensation should be the same, the brightness of each green pixel in the same row of pixels after compensation should be the same, and the brightness of each blue pixel in the same row of pixels after compensation should be the same. Therefore, the average value of each compensated voltage parameter of the pixels in the same row 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 of the pixels in the row reaching the same brightness).
If the average value is larger than the preset average value and the difference between the average value and the preset average value is larger than the threshold range, or if the average value is smaller than the preset average value and the difference between the average value and the preset average value is larger than the threshold range, the row of pixel points are subjected to a compensation error, and the pins on the display panel corresponding to the row of pixel points are connected with the pins of the compensation equipment to be staggered, so that the inspection and the correction are required.
In other embodiments, it may be determined that the average value is smaller than the predetermined average value and the difference between the average value and the predetermined average value is greater than the threshold range, which indicates that the row of pixels has a compensation error, because a certain row of pixels is darker and a clear black line appears on the display panel, but a brighter and clear bright line does not appear, and further, to save the calculation cost, it may not be determined that the average value is greater than the predetermined average value and the difference between the average value and the predetermined average value is greater than the threshold range.
Therefore, whether the pins between the display panel and the compensation equipment are in misconnection or not can be judged by acquiring the compensation file and extracting the compensation parameters in the compensation file, so that when misconnection occurs, a worker can correct the pin lap joint in time.
According to an embodiment of the present invention, as shown in fig. 2, the step S101 of obtaining a compensation file of at least one compensated display panel includes:
s1011, obtaining compensation files of a plurality of continuous compensated display panels;
s102, extracting compensated parameters of each pixel point according to at least one compensation file comprises the following steps:
s1021, respectively extracting the compensated parameters of each pixel point in the plurality of compensation files;
s103, calculating the average value of the compensated parameters of the pixels in the same column in at least one compensated display panel comprises the following steps:
s1031, calculating an average value of compensated parameters of pixel points in the same column in the compensated display panels;
s1041, if the difference value of the compensated average value of the compensated parameter of each pixel point under the ith column in the nth compensation display panel and the preset average value is not in the threshold range, and the difference value of the compensated average value of the compensated parameter of each pixel point under the jth column in the (n + 1) th compensation display panel and the preset average value is not in the threshold range, compensating faults of each pixel point, wherein i, j, n are positive integers, i is not less than m, and j is not less than m.
According to one embodiment of the invention, i = j.
It is understood that in this embodiment, the plurality is at least two. For example, obtaining compensation files of two consecutive compensated display panels, each compensation file can obtain an average value of compensated parameters of pixels in the same row in the corresponding compensated display panel, and taking the first compensated display panel and the second compensated display panel as an example, if an average value of a fifth row of the first compensated display panel is smaller than a preset average value and a difference between the average value and the preset average value is greater than a threshold range, an average value of an eighth row of the second compensated display panel is smaller than the preset average value and a difference between the average value and the preset average value is greater than the threshold range; or if the average value of the fifth row of the first compensated display panel is smaller than the preset average value and the difference between the average value and the preset average value is larger than the threshold range, the average value of the fifth row of the second compensated display panel is smaller than the preset average value and the difference between the average value and the preset average value is larger than the threshold range; then a pin misconnection between the first compensated display panel and the second compensated display panel and the compensation device is determined. Namely, when two continuous compensated display panels are detected and found that the average value is smaller than the preset average value and the difference between the average value and the preset average value is larger than the threshold range, the pin misconnection between the display panel and the compensation equipment is judged.
In other embodiments, to avoid the occurrence of errors in the detection, a plurality of the compensated display panels may be three, four, or the like, that is, when three or four of the compensated display panels are detected to find that the average value is smaller than the preset average value and the difference between the average value and the preset average value is larger than the threshold range, it is determined that the pin connection between the display panel and the compensation device is misconnected.
I and j may be the same (high accuracy) or different (detection sensitivity may be improved). When i and j are different, i is less than or equal to m, and j is less than or equal to m. The distance between the two is m columns, alternatively m may be 800. That is, in the 800 rows, in the continuous compensated display panels, if the average value of any row in 0-800 rows is smaller than the preset average value and the difference value is larger than the threshold range, the pin misconnection between the compensated display panels and the compensation device can be determined.
The distance m between the respective i, j can be determined by compensating the coordinate positions recorded in the file. Therefore, the part of the pin lapping error in the display panel and the compensation device can be judged through the coordinate position.
Therefore, the display panel is prevented from finding the compensation error in the subsequent checking process, the detection method provided by the embodiment of the invention can detect the compensation error after the compensation, and can find the compensation error in time so as to adjust the overlapping joint of the compensation equipment and the pin of the next compensated display panel.

For example, the display module 105 may be a display, and the display includes a plurality of consecutive display color blocks, where one color block represents m rows, and m is 800, for example, that is, if a compensation error occurs in one of the same 0-800 rows of pixels of two consecutive compensated display panels, the color block corresponding to the 0-800 rows of pixels displays red, otherwise, the compensation is normal, and displays green. The number of color blocks is determined according to the total pixel row number or the total pixel column number of the compensated display panel. Therefore, through the arrangement of the display module 105, the worker can be intuitively reminded of which part of the pin of the compensation equipment is overlapped to cause a problem.
