Abstract:
The present invention discloses a brightness compensation method. The brightness compensation method includes controlling a plurality of backlights of a plurality of display areas to turn on with a plurality of backlight intensity; calculating a plurality of total backlight intensity; calculating a plurality of actual backlight intensity according to the plurality of total backlight intensity and a backlight scanning ratio; dividing a plurality of maximum backlight intensity when the plurality of backlights are fully turned on by the plurality of actual backlight intensity, to generate a plurality of compensation gains; and displaying a compensated image data with a plurality of compensated image intensity after compensating a plurality of image intensity corresponding to the plurality of display area of an image data with the plurality of compensation gains.
