Abstract

The invention relates to a corresponding stereo display device of liquid crystal barrier grid design which can improve light utilization rate. The stereo display device comprises an image display screen, a liquid crystal barrier grid layer, a wave plate and a backlight module, wherein the image display screen, the liquid crystal barrier grid layer, the wave plate and the backlight module are sequentially arranged in an overlaying mode, the liquid crystal barrier grid layer is used for displaying bright and dark stripes, and the wave plate and the backlight module achieve conversion of light polarization direction. A sub-wavelength reflection light splitting type polarization piece is applied by a liquid crystal barrier grid which conducts light reflection on a dark stripe place, and conducts light transmission on a bright stripe place, and the wave piece achieves conversion of the light polarization direction and can improve utilization rate of light. The barrier grid conducts light transmission on the bright stripe place and conducts light reflection on the dark stripe place. The barrier grid is combined with the image display screen to achieve a stereo display function, reflected light of backlight can be again reflected to the display screen, and further utilization rate of the light is improved.

Description

technical field [0001] The invention relates to the field of stereoscopic display, in particular to a liquid crystal slit barrier design capable of realizing 2D / 3D switching and improving light utilization efficiency. Background technique [0002] With the development of display technology, consumers have higher and higher requirements for display quality. Stereoscopic displays have developed rapidly in recent years because they can provide viewers with an immersive experience. Among them, autostereoscopic displays do not need to wear glasses to see stereoscopic effects, so there is a relatively broad market demand. [0003] The principle of three-dimensional display is mainly to realize the left and right eyes of people to see the pictures corresponding to the left and right eyes respectively, and the human brain fuses them to feel the three-dimensional display effect. At present, the methods for realizing left and right light splitting mainly include the cylindrical lens...
