Patent ID: 8519939

Claim:
A backlight module driving method, adapted to drive at least one backlight unit in a backlight module, wherein the backlight unit provides a surface light source to an N th area pixel of a liquid crystal display (LCD) panel of an LCD, where N is a positive integer, the backlight module driving method comprising: calculating a total time of the N th area pixel under a stable state in a frame period; and providing a control signal to drive the backlight unit within the total time of the N th area pixel under the stable state in the frame period, so as to make the backlight unit provide the surface light source to the N th area pixel, wherein a center position of a turn-on time of the control signal aligns with a center position of the total time of the N th area pixel under the stable state in the frame period, and the turn-on time of the control signal substantially does not extend into a transition state of the N th area pixel and an (N+ 1 ) th area pixel of the LCD panel, wherein the (N+ 1 ) th area pixel is close to the N th area pixel.
