Abstract: A display device and a controlling method thereof are provided. The display device includes a display panel, a backlight unit, and a time schedule controller. The display panel is configured to display images. Areas where afterimages of dynamic images occur are identified according to comparison results of dither values. Tailing phenomenon of the dynamic images may be relieved by transmitting backlight data without brightness to a second backlight sub-area corresponding to where the afterimages occur. Furthermore, because frequency multiplication is not applied, risks of display instability will not increase.

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 provides an image display method and an image display device. The image display method performs a gray-scale compensation on each data line, thereby preventing a problem of color crosstalk in a display panel. At the same time, an original image in the display panel is edge blurred, which can reduce an impact of the color crosstalk.

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.
