摘要 |
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. |

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 corresponding to the first pixel, a second voltage based on a second video signal corresponding to the second pixel and a third voltage based on a third video signal corresponding to the third pixel; wherein when (1) the first voltage is lower than a first threshold voltage and (2) the second and third voltages are higher than a second threshold voltage that is higher than the first threshold voltage, the output unit is configured to output a first corrected voltage instead of the first voltage, wherein the first corrected voltage has a value between the first voltage and the first threshold voltage. |
