Method of adjusting grayscales of display panel and display panel

In each pixel group of the pixel arrangement structure, a number of first type pixels is equal to a number of second type pixels. A number of high grayscale sub-pixels, a number of first low grayscale sub-pixels, a number of second low grayscale sub-pixels, and a number of third low grayscale sub-pixels are all equal. For each pixel group, a ratio of the high grayscale sub-pixels to the low grayscale sub-pixels is one to three to improve a display color shift.

Pixel arrangement structure, display panel, and grayscale control method

A method of compensating for data of a display panel includes: obtaining display data of an image to be displayed; determining a viewing angle improvement rate for improving viewing angle of the display panel based on the display data; obtaining a target compensation table for compensating the display panel by a preset compensation algorithm based on the viewing angle improvement rate; and compensating for the display data based on the target compensation table.

Methods of compensating for data of a display panel and display devices

A driving method for a display panel, a driving chip, and a display device are provided. By driving sub-pixels for display across multiple frames, and ensuring each sub-pixel in every frame possesses either a high or low grayscale data compensation state, and either a positive or negative polarity, it's ensured that within the same frame, among the sub-pixels with the same display color and in the high grayscale data compensation state in two neighboring sub-pixel columns, at least one sub-pixel has a different polarity from the others. Under the Tri-Gate driving architecture, pixel polarities flip at intervals of an odd number of sub-pixels in each pixel column. This reduces polarity differences between the sub-pixels with the same display color and in the high grayscale data compensation state in four adjacent sub-pixel columns. This improves the perception of brightness changes when head movement occurs and reduces the risk of nodding lines.
