Abstract:
1. A display controlling method 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 method comprising: receiving a plurality of display data of a frame; analyzing the display data to obtain a plurality of grayscale distributions corresponding to the display regions; according to each of the grayscale distributions, determining a maximum distributed grayscale of each of the grayscale distributions; according to the maximum distributed grayscale corresponding to each of the grayscale distributions, determining an adjustment gain corresponding to each of the grayscale distributions; according to the adjustment gains of the grayscale distributions, generating a plurality of data adjusting signals; according to the data adjusting signals, adjusting grayscales of the display data corresponding to the display regions; according to the grayscale distributions, generating a backlight controlling signal for adjusting a brightness of each of the light emitting groups; according to the backlight controlling signal, obtaining a plurality of interferences corresponding to the display data; and according to the interferences, correspondingly adjusting the grayscales of the display data.
