Abstract: A method and an apparatus for driving a display panel, and a display driver integrated circuit chip are provided. The method includes: determining an order in which display divisions on the display panel are to be driven, when determined not to update respective refresh rates of the display divisions; determining electric signal gear ranges for the display divisions based on the refresh rates of the display divisions, respectively; and driving the display divisions sequentially in the determined order and based on the determined gear ranges. With this method, the power consumption can be reduced while the display effect is improved.

Abstract: Provided are a display panel, a driving method of a display panel, and a display device. The display panel includes a first display region and a second display region. A working process of the display panel includes a first mode. In the first mode, a data refresh rate of the first display region is F11, a data refresh rate of the second display region is F21, and F11≠F21. In the first mode, a driving parameter of the first display region is different from a driving parameter of the second display region, the driving parameter of the first display region is used for controlling brightness of the first display region, and the driving parameter of the second display region is used for controlling brightness of the second display region.
