1. A method of driving a display device, comprising:
acquiring a picture to be displayed;
determining whether the picture to be displayed is a heavy-loaded picture;
adjusting a first gamma voltage corresponding to the picture to be displayed to a second gamma voltage if the picture to be displayed is the heavy-loaded picture, wherein a voltage value of the second gamma voltage corresponding to a same grayscale is less than a voltage value of the first gamma voltage; and
driving the display device to display the picture to be displayed according to the second gamma voltage,
wherein the step of determining whether the picture to be displayed is a heavy-loaded picture comprises:
acquiring brightness distribution characteristics of the heavy-loaded picture;
acquiring brightness distribution characteristics of the picture to be displayed;
comparing the brightness distribution characteristics of the heavy-loaded picture with the brightness distribution characteristics of the picture to be displayed, and determining the picture to be displayed is the heavy-loaded picture if the brightness distribution characteristics of the heavy-loaded picture are same as the brightness distribution characteristics of the picture to be displayed.
