Description

Double-vision 3D display device based on polaroid

Technical Field

The utility model relates to a 3D shows, more specifically says, the utility model relates to a double vision 3D display device based on polaroid.

Background

The double-view display displays two different pictures on the same display screen, and the different pictures are seen in different viewing directions. The integrated imaging double-view 3D display is to fuse the integrated imaging display and the double-view display and see different 3D pictures in different viewing directions. However, in conventional integrated imaging dual view 3D display, both the image elements and the pinholes are square, i.e. the horizontal pitch of the image elements and the pinholes is equal to the vertical pitch. The horizontal width and the vertical width of the display are not equal, so that the traditional integrated imaging double-vision 3D display has the problem of uneven resolution. The resolution of the integrated imaging dual view 3D display is a few tenths of the resolution of the 2D display. Therefore, the non-uniformity of the resolution deepens the problem of poor viewing experience due to low resolution.
