ABSTRACT:
The invention prevents display tearing involved with refreshing of a display memory when grayscale data corresponding to a pixel is read from the display memory and is displayed on a display panel. If a refresh has occurred during a reading and scanning operation of a display memory, a display controller skips the reading operation of the grayscale data corresponding to rows subsequent to the row which was being read and scanned when the refresh occurred. The content from a frame immediately before the frame in which the refresh occurred is maintained in the skipped pixel.
