Abstract

Provided is a projection display device for displaying a time period of one frame of stereo image as a first modulation period. The projection display device includes: a light source for emitting illumination light; a spatial light modulator for modulating the illumination light according to a plurality of frames of two-dimensional images corresponding to a stereo image to be displayed, and sequentially emitting, within the first modulation period, image light corresponding to the plurality of frames of the two-dimensional images; an angle deflection apparatus arranged in an emergent optical path of the image light and used for deflecting the image light corresponding to the plurality of frames of two-dimensional images to different angles for emission; and a projection screen for displaying the image light deflected by the angle deflection apparatus.

A projection display device, wherein a period in which one frame of stereo image is displayed is referred to as a first modulation cycle, and the projection display device comprises:

a light source, configured to emit illumination light;
a spatial light modulator, configured to modulate the illumination light based on a plurality of frames of 2D images corresponding to a stereo image to-be-displayed, and sequentially emit, in the first modulation cycle, image light corresponding to the plurality of frames of 2D images;
an angle deflection apparatus, disposed on an emergent optical path of the image light, and configured to deflect the image light corresponding to the plurality of frames of 2D images to different angles for emission;
and
a projection screen, configured to display the image light deflected by the angle deflection apparatus.
