  • Publication number: 20120056915
    Abstract: An overshooting process is carried out, in an LCD device (1) whose LC layer thicknesses meet pixel R>pixel G>pixel B, so as to respectively set first through third output gray scales of current frame based on (i) first through third input gray scales of the current frame (current frame data) and (ii) first through third gray scales of frame which is one frame before the current frame (previous frame data). The first through third output gray scales are respectively set for the first through third pixels based on the thicknesses of the respective first through third liquid crystal layers so as to meet pixel R>pixel G>pixel B. This equalizes liquid crystal response speeds of the respective pixels R, G, and B, and therefore allows an improvement in display quality of the LCD device (1) having a multi gap structure.
