CRYSTAL DISPLAY DEVICE

摘要

An image is sensed whether to be edged by judging whether the difference between data on a pixel with an edge sensing circuit and data on an adjacent pixel above a threshold value. From the sensing result, if the image of a certain pixel part is regarded as an edged image, an emphasis converting section stops OS drive on the basis of the sensing result of the edge sensing circuit. If the image of a pixel part is not regarded as an edged image, the converting section carries out OS drive. Thus, the edge sensing circuit verifies an edge part of an input image to control the ON/OFF state of the OS drive at the emphasis converting section.
