Problems solved by technology

Therefore, the sync signal receiver 41 often cannot be correctly synchronized with the sync signal transmitter 21 of the display 20 because the infrared rays are blocked or the intensity of the infrared rays is insufficient.
[0006] As a result, the liquid crystal shutter glasses 40 will mistakenly open and close the liquid crystal shutters due to incorrect synchronization, and make it impossible for viewers to watch stereoscopic images.

Abstract

The invention relates to a stereoscopic image display system, a display and a backlight module control method thereof. The stereoscopic image display system comprises a display and a pair of stereoscopic image glasses with a sensor. The display comprises a backlight driver module and a backlight module, wherein the backlight driver module modulates an initial backlight driver signal to generate amodulated backlight driver signal so as to drive the backlight module to output backlight. The display simultaneously generates a left eye image and a right eye image alternatively according to a stereoscopic image signal. The sensor of the stereoscopic image glasses judges the output of the display to be the left eye image or the right eye image according to the variation of the backlight intensity.

Description

technical field [0001] The present invention relates to an image display system, a display included in the image display system, and a control method for a backlight module of the display; in particular, a stereoscopic image display system, a display for providing a stereoscopic image, and a backlight module for the display Control Method. Background technique [0002] In order to provide users with more realistic image effects, there are more and more displays in the display industry that can provide viewers with stereoscopic visual effects. Please refer here figure 1 A conventional stereoscopic image display system 10 is shown. like figure 1 As shown, the conventional stereoscopic image display system 10 includes a display 20 , a computer 30 and liquid crystal shutter glasses 40 , wherein a signal connection is established between the display 20 and the computer 30 for the computer 30 to transmit the stereoscopic image signal to the display 20 . The display 20 will div...
