Abstract
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.

(canceled)
A method for driving a display device, comprising:
- a first step of performing a frame interpolation processing to produce a plurality of frames;
- a second step of performing a first super-resolution processing of a m-th frame in the plurality of frames to produce a m-th super-resolution frame;
- a third step of performing a second super-resolution processing of a (m+1)-th frame to produce a (m+1)-th super-resolution frame;
- and
- a fourth frame of an enlargement processing of the m-th super-resolution frame and the (m+1)-th super-resolution frame,
- wherein m is a natural number more than 0,
- wherein the plurality of frames includes the m-th frame and the (m+1)-th frame, and
- wherein the second step and the third step are performed concurrently after the first step.
