Abstract: A pixel structure driving method and a display device are provided. The driving method includes obtaining a polarity of each of the data lines of a current frame, determining a polarity of each of the sub-pixels according to the polarity of each of the data lines and an arrangement of the pixel structure, performing a value look-up process according to a polarity and an initial gray value of each of the sub-pixels to obtain a polarity high/low gray value of each of the sub-pixels, if a luminance of a high gray value of a positive polarity of a sub-pixel of a color is different from a luminance of a high gray value of a negative polarity of the sub-pixel of the color, adjusting the polarity high/low gray value of the sub-pixel. In this way, the occurrence of vertical strips in a still image could be alleviated.

Abstract: The application provides a display panel and a driving method thereof. The display panel comprises a plurality of sub-pixels arranged in a matrix, and the sub-pixels are grouped into a plurality of cell areas arranged repeatedly along the row direction and the column direction. Each cell area comprises at least two sub-pixels, with polarities of adjacent sub-pixels opposite to each other. For at least two consecutive frames during a display cycle, the gray-levels of sub-pixels in the cell area maintain unchanged while polarities of the sub-pixels are reversed.

Abstract: A display panel includes a plurality of pixel units arranged in an array and a plurality of data lines. The pixel units in two adjacent rows in two adjacent columns form a grayscale combined pixel. The grayscale combined pixel comprises three sub-pixels corresponding to the high grayscale and nine sub-pixels corresponding to the low grayscale.

Abstract: A display panel, and a method and a device for pixel compensation thereof are provided. The method includes receiving a signal of a frame of image, obtaining grayscale compensation data, and compensating the grayscale data. In the image in a same frame, polarities of grayscale compensation data of two adjacent sub-pixels are opposite. In a time period unit, respective polarities of high grayscale compensation data and low grayscale compensation data of each of the sub-pixels remain symmetrical.

Abstract: The present application discloses a timing controller, a polarity grayscale compensation method, and a display panel. The timing controller includes a viewing angle compensation module, an overdriving module, a lookup module, and a compensation module. A corresponding grayscale compensation table is looked up according to a comparison result of a previous frame image data and a current frame image data, a grayscale compensation is performed on the current frame image data after overdriving processing to generate a data signal after grayscale compensation, which can decrease occurrences of bright and dark lines when time-domain viewing angle compensation is switched between frames.

Abstract: The present disclosure provides a display device and a display method thereof. When a change of a grayscale data of a sub-pixel between a current frame and a previous frame, and a change of a polarity of a data voltage of the sub-pixel between the current frame and the previous frame satisfy a compensation condition, the grayscale data of the sub-pixel in the current frame is compensated.
