Patent ID: 8217969

Claim:
A display controlling module for a display device having a backlight module and a display panel, wherein the backlight module has a plurality of light emitting groups and the display panel has a plurality of display regions, the display controlling module comprising: a data analyzing unit for receiving a plurality of display data of a corresponding frame, analyzing the display data to obtain a plurality of grayscale distributions of the corresponding display regions and generating a backlight signal for adjusting a brightness of each of the light emitting groups according to the grayscale distributions; an interference data storage unit coupled to the data analyzing unit, wherein the interference data storage unit outputs a plurality of interferences of the corresponding display data according to the backlight controlling signal; and a data adjustment unit coupled to the data analyzing unit and the interference data storage unit, wherein the data adjustment unit receives the display data and the interferences and correspondingly adjusts grayscales of the display data according to the interferences, wherein the data analyzing unit determines a maximum distributed grayscale of each of the grayscale distributions according to each of the grayscale distributions, determines an adjustment gain corresponding to each of the grayscale distributions according to the maximum distributed grayscale corresponding to each of the grayscale distributions and generates a plurality of data adjusting signals according to the adjustment gains of the grayscale distributions, wherein the data analyzing unit further generates the data adjusting signals to the data adjustment unit and the data adjustment unit correspondingly adjusts the grayscales of the display data corresponding to the display regions according to the data adjusting signals.
