Abstract:
1. A display device for a user seeing an image displayed by the display device through a pair of polarization glasses to obtain a stereo image, the display device comprising: a projector sequentially displaying a first image, a first middle image, a second image, and a second middle image on a projection screen; a switchable polarizer located between the projection screen and the projector, the switchable polarizer being switchable between a first mode and a second mode, such that each of a light of the first image and another light of the second image has a first polarization state or a second polarization state after passing through the switchable polarizer in the first mode or the second mode and is projected onto the projection screen; and a sensor coupled to the switchable polarizer, the sensor sensing the images on the projection screen, wherein when the sensor senses the first middle image or the second middle image, the switchable polarizer switches from one of the first mode and the second mode to the other.
