Abstract:
1. A display system capable of switching two-dimensional (2D)/three-dimensional (3D) mode, the display system comprising: a signal source for transmitting a vertical synchronization signal and a left eye/right eye control signal; a 3D backlight control signal generation circuit coupled to the signal source for executing a first logic operation on the vertical synchronization signal and the left eye/right eye control signal to output a 3D left eye backlight control signal, and executing a second logic operation on the vertical synchronization signal and the left eye/right eye control signal to output a 3D right eye backlight control signal; a 2D/3D switching circuit coupled to the signal source for outputting a 2D/3D switching signal according to the vertical synchronization signal and the left eye/right eye control signal; a 2D backlight control signal generation circuit coupled to the signal source for executing a first logic operation on the vertical synchronization signal and the left eye/right eye control signal to output a 2D left eye backlight control signal and a 2D right eye backlight control signal; a first multiplexer having a first input terminal for receiving the 2D/3D switching signal, a second input terminal for receiving the 2D left eye backlight control signal, a third input terminal for receiving the 3D left eye backlight control signal, and an output terminal for outputting the 2D left eye backlight control signal or the 3D left eye backlight control signal; a second multiplexer having a first input terminal for receiving the 2D/3D switching signal, a second input terminal for receiving the 2D right eye backlight control signal, a third input terminal for receiving the 3D right eye backlight control signal, and an output terminal for outputting the 2D right eye backlight control signal or the 3D right eye backlight control signal; and a display for displaying 3D images in a 3D mode according to the 3D left eye backlight control signal and the 3D right eye backlight control signal, or displaying 2D images in a 2D mode according to the 2D left eye backlight control signal and the 2D right eye backlight control signal.
