Background

The naked eye 3d display can obtain a display system with a realistic stereoscopic image of space and depth by utilizing the characteristic that both eyes of a person have parallax without any auxiliary equipment (such as 3d glasses, helmets and the like). The naked eye 3D liquid crystal display screen generally adopts a cylindrical lens structure, and the principle of the cylindrical lens 3D technology is that a layer of cylindrical lens is added in front of the liquid crystal display screen, so that the image plane of the liquid crystal display screen is positioned on the focal plane of the lens, and thus, the pixels of the image under each cylindrical lens are divided into a plurality of sub-pixels, and each sub-pixel can be projected by the lens in different directions. Thus, both eyes view the display screen from different angles and see different sub-pixels. However, the inter-pixel gaps are also enlarged and thus the sub-pixels cannot be simply superimposed.
