  • Publication number: 20230178042
    Abstract: A ghost elimination method, a ghost elimination device and a display panel are provided. The ghost elimination method includes driving and displaying a display panel by taking a plurality of continuous frames of pictures as a period. In one period, motion compensation is performed on the front m frames of pictures, and the motion compensation is not performed on the remaining n frames of pictures, where m and n are both positive integers.

  • Patent number: 11636830
    Abstract: The present disclosure discloses a driving method and apparatus of a display panel. When each of a plurality of obtained display frames is transmitted, only display data, corresponding to each pixel in one row group, in the display frame of image data is transmitted to a driving chip in the display panel, so that the driving chip in the display panel drives the display panel to display an image according to the received display data. Therefore, when a system on chip transmits each of the plurality of obtained display frames, only the display data, corresponding to each pixel in one row group, in the display frame of image data is transmitted to the driving chip in the display panel.

  • Patent number: 11455929
    Abstract: The present disclosure discloses a driving method and apparatus of a display panel. When the display panel is driven to display a (2k?1)th image, only display data, corresponding to pixels of one row group, in image data of a kth display frame of a plurality of display frames are transmitted to a driver chip in the display panel, and a data size transmitted may be reduced. When the display panel is driven to display a (2k)th image, display data, corresponding to pixels of another row group, in the image data of the kth display frame are transmitted to the driver chip in the display panel, and the data size transmitted may also be reduced.

  • Patent number: 11289038
    Abstract: The present disclosure relates to the field of display technology and, in particular, to a pixel charging method, a pixel charging circuit, a display device, and a display control method. The pixel charging method includes acquiring a state of a backlight source and adjusting a charging time of a sub-pixel corresponding to the backlight source according to the state of the backlight source. When the backlight source is in an on state, the charging time of the sub-pixel corresponding to the backlight source is a first charging time. When the backlight source is in an off state, the charging time of the sub-pixel corresponding to the backlight source is a second charging time, the second charging time being shorter than the first charging time.
