Abstract

A three-dimensional stereo display, and a system and method are provided for controlling the three-dimensional stereo display. The three-dimensional stereo display includes backlight, a first polarizer, a first liquid crystal panel, a second polarizer and a second liquid crystal panel which are sequentially arranged on the backlight source. The second liquid crystal panel switches the polarizing angle of the light travelling through and exiting from said second liquid crystal panel between a horizontal and vertical polarization. Due to the polarization direction of light could be changed by the liquid crystal panel, and makes the light for the left-eye image and the right-eye image are mutual perpendicular. The polarization direction of the light for the left-eye image is the same as that of the left lens, and the polarization direction of the light for the right-eye image is the same as that of the right lens. So the light belongs to the left-eye image or the right-eye image can pass through the left lens or the right lens respectively, then a stereo image will emerge in people's brain due to the effect of “fusion activity”. Further, there is no need to close the polarized spectacles, the displaying efficiency is improved compared with the “Active Stereo”.
