DISPLAY SYSTEM AND DRIVING METHOD OF BACKLIGHT MODULE THEREOF

摘要

A driving method for a display system including a display panel and a backlight module is provided. A first directional surface light source and a second directional surface light source are respectively provided by a first light source and a second light source of the backlight module through a light guide plate. Images displayed by the display panel are thus transmitted to a left eye and a right eye. A data enable signal and an image signal are received to determine whether the image signal transmits a two dimensional image or a stereoscopic image according to the data enable signal. When the image signal is the two dimensional image, the first light source and the second light source are turned on simultaneously. When the image signal is the stereoscopic image, the first light source and the second light source are turned on at corresponding display periods, respectively.
