Method for driving display device
A low-resolution image is displayed at higher resolution and afterimages are reduced. Resolution is made higher by super-resolution processing. In this case, the super-resolution processing is performed after frame interpolation processing is performed. Further, in that case, the super-resolution processing is performed using a plurality of processing systems. Therefore, even when frame frequency is made higher, the super-resolution processing can be performed at high speed. Further, since frame rate doubling is performed by the frame interpolation processing, afterimages can be reduced.
1. A method for driving a display device, comprising:
performing a frame interpolation processing;
performing a super-resolution processing after the frame interpolation processing; and
performing an overdrive processing after the super-resolution processing,
wherein the super-resolution processing is performed in a first part of a screen,
wherein the overdrive processing is performed in a second part of the screen, and
wherein the first part of the screen overlaps with the second part of the screen.
