Detailed Description
In order to make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be further described in detail with reference to the accompanying drawings.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating a display panel compensation method according to an embodiment of the invention. The compensation method in this embodiment can be used to solve the mura problem of the display panel. The compensation method specifically comprises the following steps:
step S101: dividing the pixel array into at least one sub-array, and acquiring compensation values of four pixel points in the sub-array at a first gray scale and a second gray scale respectively; wherein, four pixel points are respectively positioned at four corners of the subarray.
In this step, the pixel array on the display panel may be divided into a plurality of sub-arrays, and the compensation value may be calculated for each sub-array.
Taking one of the sub-arrays as an example, please refer to fig. 2, fig. 2 is a schematic distribution diagram of four pixel points selected in the sub-array in step S101 of the present invention, in which the sub-array 20 includes four pixel points respectively located at four corners of the sub-array 20, which are respectively a first pixel point 211, a second pixel point 212, a third pixel point 233, and a fourth pixel point 234.
The specific method for obtaining the compensation values of the four pixel points in the sub-array at the first gray scale and the second gray scale respectively may be that when the display panel is arranged on the first gray scale picture, for example, when the first gray scale picture of the display panel is arranged at the gray scale 25, the display panel is detected by an optical detection device that accurately detects optical data such as brightness or chromaticity, the optical data such as brightness or chromaticity of the four pixel points at the four corners of the sub-array in the pixel array on the display panel is determined, and then the compensation values of the four pixel points when the picture of the display panel is at the gray scale 25 are obtained by the detected optical data. And the compensation values of the four pixel points in the second gray scale picture can be obtained by analogy.
In other embodiments, in order to make the selection of the pixel point more flexible, other pixel points other than four pixel points at four corners of the sub-array may also be selected. Referring to fig. 3, fig. 3 is another schematic distribution diagram of four pixel points selected from the sub-array in step S101 according to the present invention. The first pixel 211, the second pixel 212, the third pixel 233 and the fourth pixel 234 are not all pixels at four corners of the sub-array. The first pixel 211 and the second pixel 212 are located in the first row 21, the third pixel 233 is located in the second row 23, and the fourth pixel 234 is not located in the first row 21 and is in a different column from the third pixel 233. The fourth pixel point 234 and the third pixel point 233 may be in the same row or in different rows, and the third pixel point 233 may be in the same column or not in the same column as the first pixel point 211 or the second pixel point 212.
Therefore, the compensation values of the four pixel points in the first gray scale and the second gray scale picture can be obtained through the step.
Further, the pixel array of the display panel may be divided into a plurality of sub-arrays, the number of rows or columns of which is a multiple of 2. For example, the number of rows of a sub-array is 8 rows and the number of columns is 8 columns. And then, the compensation values of at least four pixel points in at least two gray scales are respectively obtained from each sub array, so that the number of samples for selecting the four pixel points can be increased, and the error is reduced.
Step S102: and obtaining compensation values of the pixel points at non-four corners in the subarray at the first gray scale and the second gray scale respectively by a bilinear interpolation method according to the compensation values of the four pixel points at the first gray scale and the second gray scale respectively.
When the four pixel points selected in step S101 are four pixel points on four corners of the sub-array, a bilinear interpolation method may be used to obtain compensation values of other pixel points in the sub-array. The specific method comprises the following steps:
referring to fig. 2, the selected sub-array is taken as 8 rows and 8 columns, wherein the pixel has 9 rows and 9 columns. When the display frame of the display panel is the first gray scale frame, the first pixel 211 is in the 1 st row of the 1 st column, and the compensation value is y 1; the second pixel 212 is in row 1, column 9, with a compensation value of y 2; the third pixel 233 is in row 9, column 1, with a compensation value of y 3; the fourth pixel 234 is in the 9 th row and the 9 th column, and the compensation value is y4, so the compensation value y of the pixel in the nth row and the mth column can be obtained by a bilinear interpolation method as follows:
y＝[y1*(9-m)(9-n)+y2*m(9-n)+y3*(9-m)n+y4*mn]/(8*8)
wherein a computer shift operation can be performed on the compensation value y to reduce the amount of computation. That is, the compensation value y is:
y＝[y1*(9-m)(9-n)+y2*m(9-n)+y3*(9-m)n+y4*mn]/>>6
furthermore, the compensation values of the pixel points in other sub-arrays can be obtained by a bilinear interpolation method, so that the compensation values of all the pixel points on the display panel in the first gray scale picture can be obtained. Namely, under the first gray scale picture, the compensation value of each pixel point can be obtained on the display panel, and each pixel point is further compensated through the obtained compensation value, so that the mura problem of the whole display panel can be accurately and effectively solved.
It should be understood that the above method is to perform the compensation value calculation by selecting 4 pixels at 4 corners of the sub-array. However, if the compensation values of the selected 4 points are the same and the sub-array has a problem of poor display effect, the compensation values of all the pixels in the calculated sub-array are the same as the compensation values of the selected four pixels, so that the compensation effect of the area having the problem of poor display effect is not good enough. Therefore, at least one pixel point is selected from the area with poor display effect in the sub-array to perform compensation value operation. That is, the selected four pixel points are not all 4 pixel points on the 4 corners of the sub-array.
For the condition that the selected four pixel points are not all 4 pixel points on the 4 corners of the subarray, the compensation value of the pixel point in a gray-scale picture can be obtained by using a linear interpolation method. The calculation method of the compensation value comprises the steps of obtaining the compensation value of other pixel points of the same line at the gray scale through the compensation value of at least two pixel points of the same line at the same gray scale; or obtaining the compensation value of other pixel points in the row at the gray scale according to the compensation value of at least two pixel points in the same row at the same gray scale. The method adopts a linear interpolation method for operation, and comprises the following specific steps:
referring to fig. 3, a first pixel 211 and a second pixel 212 are selected, wherein the first pixel 211 and the second pixel 212 are located in the same first row 21. The first pixel point 211 is the x1 th pixel point from left to right in the first row 21, the compensation value is y1, and the second pixel point 212 is the compensation value y2 of the x2 th pixel point from left to right in this row. The compensation value of the x-th pixel point in the row from left to right is set as y, so that the compensation value y for solving the x-th pixel point is as follows:
y＝[(x2-x)y1+(x-x1)y2]/(x2-x1)
further, when the first pixel point 211, the second pixel point 212, the third pixel point 233, and the fourth pixel point 234 are respectively disposed at four end points of the pixel array, the number of rows or columns of the sub-array may be divided into multiples of 2, and when the compensation values of other pixel points on the first row 21 are calculated, the calculation amount may be reduced through a computer binary shift algorithm. For example, when the number of rows or columns of the sub-array is 8 rows and 8 columns. The first pixel point 211 is the 1 st pixel point, the second pixel point 212 is the 9 th pixel point, and the compensation value y of the x-th pixel point from left to right in the first line 21 is [ (9-x) y1+ (x-1) y2]/8, wherein the compensation value y can be obtained by performing binary shift operation by using a computer, wherein the compensation value y is [ (9-x) y1+ (x-1) y2] > > 3.
Therefore, the compensation values of other pixel points in the row at the gray scale can be obtained according to the compensation values of at least two pixel points in the same row at the same gray scale.
By the linear interpolation method described above, the compensation value of any one pixel point on the first line 21 can be obtained. That is, the fifth pixel point in the same row as the third pixel point 233 is selected from the first row 21, the compensation value of the fifth pixel point is obtained, and then the compensation value of the other pixel points in the row at the gray level is obtained through linear interpolation calculation based on the compensation values of the third pixel point 233 and the fifth pixel point in the same row at the same gray level.
Similarly, the sixth pixel point in the same column as the fourth pixel point 234 is selected from the first row 21, and the compensation value of the sixth pixel point is obtained, and then the compensation value of any other pixel point in the same column as the fourth pixel point 234 and the sixth pixel point can be obtained by the linear interpolation method described above.
Then, a seventh pixel point located in the same row as the third pixel point 233 and an eighth pixel point located in the same row as the fourth pixel point 234 are selected, and the seventh pixel point and the eighth pixel point are located in the same row, and then the compensation value of the seventh pixel point and the eighth pixel point is obtained, and the compensation value of any other pixel point in the row is obtained through the interpolation method as described above. Then, the compensation values of all pixel points on the whole pixel array can be obtained by the same method. It should be understood that the compensation values of all the pixels of one gray level are obtained at this time.
And finally, when the picture of the display panel is set to other gray scales, obtaining the compensation values of all pixel points on the display panel at the gray scale by the method.
The advantage of this scheme is that the compensation value effect of all pixel points in the whole sub-array can be further improved.
Furthermore, the compensation values of the pixel points of the display panel in the first gray scale and the second gray scale picture obtained in the above steps can also be used for obtaining the compensation values of the pixel points of the display panel in other gray scale pictures except the first gray scale and the second gray scale picture. For example, the first gray level is set to be gray level 25, and the second gray level is set to be gray level 60, so that the compensation values of the pixel point in the gray levels 0-255 can be obtained by linear interpolation according to the compensation values of the pixel point in the gray levels 25 and 60, respectively.
In other embodiments, more gray levels can be set for linear interpolation to reduce errors. For example, the compensation values of all pixels on the display panel at gray levels 25, 60 and 255 are determined by the linear interpolation method described above. Based on the compensation values of the pixel point in the gray levels 25 and 60, the compensation values of the pixel point in the other gray levels 25-60 are obtained through linear interpolation calculation. The gray scale 0 is a pure black picture, so that the compensation values of all pixel points of the display panel can be considered to be 0, and the compensation values of the pixel points in other gray scales of 0-25 gray scales can be obtained through linear interpolation calculation. Meanwhile, compensation values of the pixel point in other gray scales of the gray scales 60-255 can be obtained through linear interpolation calculation based on the compensation values of the pixel point in the gray scales 60 and 255.
Optionally, the compensation values of all the pixels on the display panel at 4 or more than 4 gray levels can be determined, and the compensation values of all the pixels on the display panel at each gray level can be obtained by interpolation, so as to reduce the error.
The embodiment provides a compensation method for a real panel, which includes selecting 4 pixel points on a display panel under a certain gray scale and obtaining compensation values of the 4 pixel points, then obtaining compensation values of all pixel points on the whole display panel at the gray scale by a linear interpolation method, then determining compensation values of all pixel points on the whole display panel at a plurality of gray scales, and further obtaining compensation values of all pixel points on the display panel at each gray scale by an interpolation method. And then, compensating each pixel point on the display panel by the finally obtained compensation value of all the pixel points on the display panel in each gray scale, thereby effectively improving the mura problem of the display panel.
The embodiment of the invention also provides compensation equipment of the display panel. Referring to fig. 4, fig. 4 is a schematic structural diagram of a compensation apparatus of a display panel according to an embodiment of the present invention. Wherein the compensation device 40 comprises a processor 41 and a memory 42, wherein the memory 42 is used for storing program data, which is loaded and executed by the processor 41 to implement the compensation method described above. For a specific compensation method, please refer to the foregoing embodiments, which are not described herein.
