Double-vision 3D display device based on point light source array

Abstract

The invention discloses a double-vision 3D display device based on a point light source array. The double-vision 3D display device comprises an active light emitting type display screen, a polarization grating, a transmission type display screen, polarization glasses I and polarization glasses II. A plurality of point light sources which are continuously arranged in the horizontal direction and aplurality of corresponding image elements I which are continuously arranged in the horizontal direction are correspondingly aligned with a same grating unit I; a plurality of point light sources whichare continuously arranged in the horizontal direction and a plurality of corresponding image elements II which are continuously arranged in the horizontal direction are correspondingly aligned with asame grating unit II; light emitted by the point light sources illuminates the image elements I through the grating unit I corresponding to the point light sources to reconstruct a 3D image I; the light emitted by the point light sources illuminates the image elements II through the grating unit II corresponding to the point light sources to reconstruct a 3D image II; and only the 3D image I canbe seen through the polarization glasses I, and only the 3D image II can be seen through the polarization glasses II.

Description

technical field [0001] The present invention relates to 3D display, and more specifically, the present invention relates to a dual-view 3D display device based on a point light source array. Background technique [0002] Integrated imaging dual-view 3D display is the fusion of dual-view display technology and integrated imaging 3D display technology. It can make viewers see different 3D images in different viewing directions. However, the traditional integrated imaging dual-view 3D display has the disadvantage of separation of the two viewing areas. The viewer needs to move the viewing position to see another picture, which limits the application of integrated imaging dual-view 3D display in home entertainment equipment and medical equipment to a certain extent. Two different 3D images can be separated by using a polarizing grating and matching polarizing glasses, and viewers can see different 3D images by switching different polarizing glasses. [0003] The traditional p...
