Abstract:
1. A liquid crystal display device for displaying video data, comprising: a detection circuit for detecting a luminance distribution in one frame period, the luminance distribution being indicative of generation frequency of gradations in each of a plurality of divided regions, each divided region including a plurality of gradations based on the video data which is inputted, a determination circuit for determining a divided region of higher generation frequency of gradation than that all of other divided regions based on the luminance distribution in one frame period, a memory for delaying the video data which is inputted by one frame period, a correction circuit for correcting the video data which is delayed by one frame period so as to make a luminance characteristic of the divided region of higher generation frequency of gradation more abrupt than a luminance characteristic of the other divided regions, and a display panel for displaying the corrected video data.
