Double-vision 3D display device based on rectangular pinhole array

Abstract

The invention discloses a double-vision 3D display device based on a rectangular pinhole array. The double-vision 3D display device comprises a display screen, a polarization grating, the rectangularpinhole array, polarization glasses I and polarization glasses II; the rectangular pinhole array comprises a plurality of groups of rectangular pinholes; a plurality of rectangular pinholes corresponding to a same rectangular image element I are symmetrical by taking the center of the rectangular image element I as the center; a plurality of rectangular pinholes corresponding to a same rectangularimage element II are symmetrical by taking the center of the rectangular image element II as the center; a plurality of rectangular image elements I which are continuously arranged in the horizontaldirection are correspondingly aligned with a same grating unit I; a plurality of rectangular image elements II which are continuously arranged in the horizontal direction are correspondingly aligned with a same grating unit II; the polarization direction of the polarization glasses I is the same as that of the grating unit I, and the polarization direction of the polarization glasses II is the same as that of the grating unit II; and only the 3D image I can be 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 rectangular pinhole 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] By adopting a te...

AI Technical Summary

Problems solved by technology

However, the traditional integrated imaging dual-view 3D display device based on a polarization grating and a rectangular pinhole array has the following disadvantages: the pitch of the grating unit is equal to the horizontal pitch of the rectangular pinholes

Therefore, the larger the horizontal resolution, the more difficult and expensive it is to manufacture the polarization grating
