Claim Text:
1. A display system, comprising: a light sensor, for detecting frequency of ambient light; a display device, comprising a 3D display mode and a 2D display mode, wherein when the display device is in the 3D display mode, the display device alternately displays a left image and a right image, and when the display device is in the 2D display mode, the display device displays a 2D image; a pair of shutter glasses, wherein when the display device displays the left image, a left shutter of the pair of shutter glasses is turned on, when the display device displays the right image, a right shutter of the pair of shutter glasses is turned on, and when the display device displays the 2D image, the left and right shutters are both turned on; and a controller, wherein when the display device is in the 2D display mode, the controller updates frequency of the display device according to the frequency of the ambient light, and when the display device is in the 3D display mode, the controller updates the frequency of the display device and adjusts a shutter frequency of the pair of shutter glasses according to the frequency of the ambient light; wherein when the display device is in the 2D display mode and the frequency of the ambient light is higher than a threshold value, the controller updates the frequency of the display device to substantially equal a first frequency, when the display device is in the 2D display mode and the frequency of the ambient light is lower than the threshold value, the controller updates the frequency of the display device to substantially equal a second frequency, when the display device is in the 3D display mode and the frequency of the ambient light is higher than the threshold value, the controller updates the frequency of the display device to substantially equal twice the first frequency, and adjusts the shutter frequency of the pair of shutter glasses to substantially equal twice the first frequency, and when the display device is in the 3D display mode and the frequency of the ambient light is lower than the threshold value, the controller updates the frequency of the display device to substantially equal twice the second frequency, and adjusts the shutter frequency of the pair of shutter glasses to substantially equal twice the second frequency.
