Patent ID: 8411004

Claim:
A video processing circuit for a liquid crystal panel including a first substrate in which a pixel electrode is disposed corresponding to each of a plurality of pixels, a second substrate in which a common electrode is disposed, and liquid crystal interposed between the first substrate and the second substrate, the pixel electrode, the liquid crystal, and the common electrode constituting each of liquid crystal elements, the video processing circuit inputting a video signal which specifies an applied voltage to the liquid crystal element for each of the pixels and defining the applied voltage to each of the liquid crystal elements based on a processed video signal, the video processing circuit comprising: a boundary detecting unit which detects a boundary between a first pixel whose applied voltage specified by an input video signal is below a first voltage and a second pixel whose applied voltage is equal to or higher than a second voltage which is higher than the first voltage; and a correction unit which corrects, for at least two pixels of a second plurality of pixels one of which is adjacent to the boundary detected by the boundary detecting unit on the opposite side of the first pixel and which are successive in a direction opposite to the boundary, an applied voltage to liquid crystal elements corresponding to the second plurality of pixels from the applied voltage specified by the video signal to a voltage which is equal to or higher than the first voltage and below the second voltage.
