Three-dimensional display system, display and method of controlling backlight of three-dimensional display

摘要

A three-dimensional display system including a display and a pair of three-dimensional glasses having a light sensor is provided. The display includes a backlight driving module and a backlight module, wherein the backlight driving module modulates an original synchronization signal to generate a modulated backlight driving signal for driving the backlight module to generate a backlight. The display alternatively generates a left eye image and a right eye image according to a three-dimensional image signal. The three-dimensional glasses then determines whether the image output from the display is the let-eye image or the right-eye image based on the variation in brightness of the backlight generated by the backlight module of the display.
