发明名称 LIQUID CRYSTAL DISPLAY
摘要 In a display apparatus having a liquid crystal panel, a change in luminance of the entire display frame when overshoot driving is performed is suppressed, while improving a viewing angle of the liquid crystal panel. A processing unit performs a high gradation display displaying a gradation higher than a gradation of an input image at one of two adjacent pixels, performs a low gradation display displaying a gradation lower than a gradation of an input image at the other of the two adjacent pixels, and switches between the high gradation display and the low gradation display for each pixel every display frame. A correction unit corrects a gradation of a pixel located adjacent to a pixel displayed with a gradation for which predetermined overshoot driving is difficult in the next display frame to a gradation for which overshoot driving stronger than the predetermined overshoot driving is possible.

主权项 1. A liquid crystal display apparatus comprising: a liquid crystal panel having a plurality of pixels disposed in a matrix pattern; and a viewing angle improvement unit that performs a process of improving a viewing angle of the liquid crystal panel, wherein the viewing angle improvement unit includes: a processing unit that performs a high gradation display displaying a gradation higher than a gradation of an input image at one of two adjacent pixels, performs a low gradation display displaying a gradation lower than a gradation of an input image at the other of the two adjacent pixels, and switches between the high gradation display and the low gradation display for each pixel every display frame; and a correction unit that corrects a gradation of a pixel located adjacent to a pixel displayed with a gradation for which predetermined overshoot driving is difficult in the next display frame to a gradation for which overshoot driving stronger than the predetermined overshoot driving is possible, and wherein, when there is the pixel displayed with a gradation for which predetermined overshoot driving is difficult, the processing unit displays a pixel located adjacent to the pixel displayed with a gradation for which predetermined overshoot driving is difficult, with the gradation corrected by the correction unit.
