  • Patent number: 11393420
    Abstract: A display device, a pixel circuit and its driving method and driving device. The driving method includes the steps of, during a frame sequence formed by successive X frames of image displaying, outputting gate signals and data signals to the pixel circuit in a first preset mode; during a frame sequence formed by successive Y frames and adjacent to the frame sequence formed by successive X frames of image displaying, outputting gate signals and data signals to the pixel circuit in a second preset mode, wherein the first preset mode is different from the second preset mode, and X and Y are positive integers not less than 2. The method can enable the charging time of the pixel circuit to be balanced in space, thereby improving image display quality.
    Type: Grant
