Abstract: A display panel is divided into multiple areas respectively driven by multiple drivers, and the multiple areas are adjacent to each other along a first direction. An object moves along the first direction between a first frame and a second frame and is displayed on the display panel. The moving speed of the object is compared with a reference speed. A main compensation frame is added between the first frame and the second frame. A first high speed compensation frame is added between the first frame and the main compensation frame when the moving speed is higher than or equal to the reference speed. A first low speed compensation frame is added between the first frame and the main compensation frame when the moving speed is lower than the reference speed, and the first low speed compensation frame is different from the first high speed compensation frame.
