Title:
A graphic processing circuit, the graphic processing method, an electrooptics device, and electronic equipment
Document Type and Number:
Japanese Patent JP6233047
Kind Code:
B2
Abstract:
A video processing circuit detects a boundary between a first pixel to which an application voltage which is a first voltage is applied, and a second pixel to which an application voltage which is a second voltage higher than the first voltage is applied, based on a video signal indicating a video which alternately switches a first video and a second video which is obtained by moving in parallel with the first video for each unit frame, corrects the application voltage such that a fringe electric field occurring at the boundary is decreased, when determining a boundary detected by the boundary detection unit in a kth unit frame does not exist in a (k−2)th unit frame, and the boundary is a boundary which is moved from a (k−1)th unit frame to the kth unit frame, and outputs the corrected video signal such that the liquid crystal panel is driven.
