1. A method for controlling a display device in a pulse width modulation (PWM) driving mode, comprising:
obtaining, by a controller, a type of display contents displayed on the display device; and
controlling, by the controller, a duty of PWM signals for driving the display device according to the type of the display contents,
wherein the duty of the PWM signals is set to a first value if the type of the display contents is a video, and the duty of the PWM signals is set to a second value larger than the first value based on a brightness setting if the type of the display contents is a static-image, wherein the duty of the PWM signals is set to a third value if a brightness level is set to a first range and the type of the display contents is the video, and the duty of the PWM signals is set to a fourth value larger than the third value if the brightness level is set to a second range higher than the first range and the type of the display contents is the static-image.
