Abstract: A display compensation method and device, and a display panel are disclosed. The display panel includes a plurality of pixel units each including a plurality of subpixels. The display compensation method includes obtaining original grayscale values of sub-images included in a pending image corresponding to the pixel units, and determining the sub-images whose original grayscale value is less than or equal to a grayscale threshold value as a target sub-image. The target sub-image is displayed through each of the subpixels of a target pixel unit corresponding to the target sub-image, and each of the subpixels of the target pixel unit has a grayscale value equal to a grayscale value of the target sub-image.

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: The present disclosure provides a display compensation method and device, and a display panel. The display compensation method includes: determining a central pixel column, a first pixel column, a second pixel column, a third pixel column, and a fourth column, in a predetermined direction; determining a target pixel area according to grayscale values of pixel units contained in each pixel column; and adjusting the grayscale value of each pixel unit in the target pixel area to be equal to one actual grayscale value of a picture to be displayed.

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 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 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.
