Liquid Crystal Display Device For Displaying Video Data |
摘要 |
A liquid crystal display device for displaying video data having a detection circuit for detecting a luminance distribution based on video data which is inputted, the luminance distribution being indicative of generation frequency of gradations in each of divided region which includes a plurality of gradations. The display device includes a determination circuit for determining at least one of a plurality of divided regions of higher generation frequency of gradation than that of other divided regions based on the luminance distribution, a correction circuit for correcting the video data so as to make a luminance characteristic of the at least one of the plurality of divided regions of higher generation frequency of gradation more abrupt than a luminance characteristic of the other divided regions, and a liquid crystal display panel for displaying the corrected video data. A width of the divided region is changeable.
