The effect of Vft (feedback voltage) caused by the coupling capacitance can lead the pixel potential to be lower than the input data potential, because the positive/negative voltage is pulled downwards by Vft, the positive voltage is usually reduced, the negative voltage is increased, the Vft of different pixels is different, although the input voltage is consistent, the final pixel voltage (Vp) is also inconsistent, and the brightness of the pixel is determined by the common electrode and Vp together, so after the VAC algorithm is applied, the brightness of the positive polarity and the negative polarity of different pixels in the minimum cycle is different, and the positive polarity and the negative polarity of different pixels are regularly distributed, and when human eyes shake according to a certain frequency, the shaking of the shaking head can be observed.

Fig. 1 is a schematic diagram of a conventional Tri-gate lcd panel, which includes a plurality of sub-pixels arranged in an array, wherein the sub-pixels include red sub-pixels R, green sub-pixels G, and blue sub-pixels B, and the red sub-pixels R, the green sub-pixels G, and the blue sub-pixels B are alternately and repeatedly arranged in sequence in each column of sub-pixels. By adopting the Tri-gate architecture, the number of scanning lines can be increased to three times, and the number of data lines is reduced to 1/3 of the original number, so that the number of data lines of the source driver is reduced, and the cost of the source driver is reduced.
Fig. 2 and 3 are two VAC adjustment schemes of the conventional Tri-gate lcd panel, wherein the display polarity includes a positive polarity and a negative polarity, the pixels in the same column are kept at the same display polarity, the gray scale values of adjacent rows are different, and the polarities of the pixels in different columns and the arrangement manner of the gray scale values are different. Fig. 2 shows HHLL pixel mapping with++ -polarity, fig. 3 shows HL pixel mapping with++ -polarity, and as shown in fig. 2 and 3, the brightness of h+ and H-is different, i.e. the gray scale value is the same, but the display polarity is different, so that the situation that one row of pixels is dark and one row of pixels is bright appears on the whole, and when the human eyes shake according to a certain frequency, the shaking marks are observed. In addition, HHLL match++ -or HL match++ -can have crosstalk, flicker and other side effects. It should be noted that the embodiments of the present application are equally applicable to other pixel architecture lcd panels, such as signal-gate, dual-gate, etc.
Referring to fig. 4, an embodiment of the present application provides a method for adjusting display brightness, which includes steps S101 to S104, specifically as follows:
s101, obtaining an original gray scale value of a picture to be displayed of a display panel and display polarity of each pixel in the display panel.
Specifically, the original gray-scale value of the picture to be displayed on the display panel and the display polarity of each pixel in the display panel are obtained, the display polarity includes a positive polarity and a negative polarity, the pixels in the same column are kept to be the same display polarity, and the display polarities of the pixels in adjacent columns may be the same or different. Fig. 5 and 8 show a certain frame to be displayed, the original gray scale values are L96, and the difference is that the display polarity of the pixels along the pixel row direction in fig. 5 is ++ - -, that is, the positive and negative alternates, and the display polarity of the pixels along the pixel row direction in fig. 8 is ++ -.
S102, determining a first gray level value and a second gray level value after the original gray level value visual angle compensation based on a preset gray level mapping table, wherein the original gray level value is arranged between the first gray level value and the second gray level value.
Specifically, a first gray level value and a second gray level value after the original gray level value viewing angle compensation are determined based on a preset gray level mapping table, and the original gray level value is arranged between the first gray level value and the second gray level value. The preset gray-scale mapping table is determined based on the principle that the brightness of the visual angle compensation is unchanged, and gray-scale values after the compensation of each gray-scale value are set in the gray-scale mapping table.
In one embodiment, the step further comprises, before: s201, obtaining pixel brightness corresponding to each gray scale value of the display panel and pixel brightness sum of two pixels with the same gray scale value; s202, determining a compensation gray scale combination of the same gray scale value according to the pixel brightness and the pixel brightness sum; s203, determining the gray scale mapping table according to the same gray scale value and the corresponding compensation gray scale combination.
Specifically, the pixel brightness corresponding to each gray scale value of the display panel and the pixel brightness sum of two pixels with the same gray scale value are obtained, and the compensation gray scale combination with the same gray scale value is determined according to the pixel brightness and the pixel brightness sum. For example, the pixel brightness of the gray level L96 is obtained, the sum of the pixel brightness of the gray level L96 is displayed by two pixels, the brightness of any two other compensating gray level combinations which are not gray levels L96 is integrated, the sum of the pixel brightness of the gray level L96 is displayed by two pixels, if the brightness of the pixel brightness is the same, the compensating gray level combination is determined to be the compensating gray level of the gray level L96, if a plurality of conforming compensating gray level combinations exist, one of the compensating gray level combinations is selected according to the requirements, for example, the compensating gray level combination with the smallest difference with the original gray level value is selected, and the compensating gray level of each gray level value is determined by analogy to obtain the gray level mapping table.
S103, determining arrangement information of the first gray scale value and the second gray scale value based on the display polarity of each pixel.
Specifically, the above-mentioned gray-scale mapping table determines only the compensation gray-scale values (the first gray-scale value and the second gray-scale value) of the original gray-scale values, but the positions where the first gray-scale value and the second gray-scale value are set affect the appearance of the pan head, and the distribution of the display polarities of the pixels is different, and the arrangement information of the corresponding first gray-scale value and second gray-scale value is different.
In one embodiment, since the shaking marks are caused by different brightness of the same gray scale value under the positive and negative polarities, the display polarities of the pixels in the same column are different, and in order to ensure uniformity of the display brightness, the positive polarity pixels and the negative polarity pixels in any view angle compensation scheme are the same, the number of the pixels corresponding to the first gray scale value is the same, the number of the pixels corresponding to the positive polarity pixels and the number of the pixels corresponding to the negative polarity pixels are the same, and the number of the pixels corresponding to the positive polarity pixels and the number of the pixels corresponding to the negative polarity pixels are the same.
In the VAC adjustment scheme of the prior art, the gray scale values of adjacent pixels in the same column are different, fig. 6 is a scheme obtained by adjusting fig. 5 by the current VAC adjustment scheme, and fig. 9 is a scheme obtained by adjusting fig. 8 by the current VAC adjustment scheme, in order to avoid new uneven brightness caused by position adjustment of the positive polarity first gray scale value, the negative polarity first gray scale value, the positive polarity second gray scale value and the negative polarity second gray scale value, in this embodiment, the display polarities of any two target pixels in the same column are different, and one pixel is arranged between the two target pixels. Fig. 7 is a view of the current VAC adjustment scheme for adjusting fig. 5, and fig. 10 is a view of the current VAC adjustment scheme for adjusting fig. 8, in which the display polarities of the pixels in the same column are not alternately arranged with positive and negative polarities, but alternately arranged with two identical display polarities.
In one embodiment, the display polarity includes positive polarity and negative polarity, the arrangement information includes row direction arrangement information of a first gray scale value and a second gray scale value, the row direction arrangement information is that the gray scale values displayed by positive polarity pixels and negative polarity pixels in the same pixel row are different, that is, in the same row of pixels, the same gray scale value corresponds to the same display polarity as much as possible, so as to avoid different brightness caused by the same gray scale value corresponding to different display polarities.
In one embodiment, step S103, determining arrangement information of the first gray scale value and the second gray scale value based on the display polarity of each pixel includes: s301, if the display polarity of each pixel is that the positive polarity pixel and the negative polarity pixel are alternately arranged on the pixel row, the row direction arrangement information is that the first gray scale value and the second gray scale value are alternately arranged on the pixel row; s302, if the display polarity of each pixel is different between any two target pixels on the pixel row, the gray scale values displayed by the two target pixels are different, and one pixel is arranged between the two target pixels.
