Description
Technical Field
The present invention relates to 3D display, and more particularly, to a dual view 3D display device based on a rectangular pinhole array.
Background
The integrated imaging double-vision 3D display is the fusion of a double-vision display technology and an integrated imaging 3D display technology. It may enable the viewer to see different 3D pictures in different viewing directions. However, the conventional integrated imaging dual-view 3D display has a disadvantage that two viewing zones are separated. The viewer needs to move the viewing position to see another picture, and the application of the integrated imaging dual-view 3D display in home entertainment equipment and medical equipment is limited to a certain extent. Two different 3D pictures can be separated by adopting the polarization grating and the matched polarization glasses, and a viewer can see different 3D pictures by switching different polarization glasses.
By adopting the technical scheme that a single rectangular image element corresponds to a plurality of rectangular pinholes, the traditional integrated imaging double-view 3D display device based on the polarization grating and the rectangular pinhole array has the advantage of high resolution. However, the conventional integrated imaging dual-view 3D display device based on the polarization grating and the rectangular pinhole array has the following disadvantages: the pitch of the grating elements is equal to the horizontal pitch of the rectangular pinholes. The number of the grating units in the polarization grating is equal to the number of the rectangular pinholes in the horizontal direction of the rectangular pinhole array. The horizontal resolution of the integrated imaging dual-view 3D display device is equal to the number of rectangular pinholes in the horizontal direction of the rectangular pinhole array. Thus, the greater the horizontal resolution, the greater the difficulty and cost of manufacturing the polarization grating.
