    IPC: G09G3/3225

    Abstract: A method for driving a display panel, a driving chip and a display device are provided to ameliorate image retention and improve the display performance. The method includes: monitoring a static pattern in a first display image and defining an area where the static pattern is located as a first area when a display brightness value of the area and a display brightness value of an area where a background pattern thereof is located satisfy a first preset condition; and controlling the static pattern to move during displaying of the first display image, or adjusting grayscale values of sub-pixels in a second area during displaying of a second display image, to which the first display image jumps, the second area being an area, corresponding to the first area in the second display image and having a display brightness value lower than a display brightness value of the first area.
