Abstract
Official abstract text for this publication.
A video processing circuit for a liquid crystal panel is disclosed. The video processing circuit includes: a risk boundary detecting unit configured to detect a risk boundary that is a portion of boundaries each between a first pixel whose applied voltage that is specified by an input video signal is below a first voltage and a second pixel whose applied voltage exceeds a second voltage higher than the first voltage, the risk boundary being determined by a tilt azimuth of the liquid crystal; an identification unit configured to identify a first pixel that is surrounded by the risk boundary at least two edges, in first pixels adjacent to the boundaries; and a replacement unit configured to replace, a voltage to be applied to a liquid crystal element corresponding to the first pixel, the voltage being specified by the input video signal, with a predetermined third voltage.
First claim
Opening claim text (preview).
What is claimed is: 1. A video processing circuit for a liquid crystal panel including at least a first pixel, a second pixel and a third pixel, the second pixel disposed at a position adjacent to the first pixel in a first direction, and the third pixel disposed at a position adjacent to the first pixel in a second direction that intersects the first direction, the video processing circuit comprising: an output unit that outputs a first voltage based on a first video signal corre…
