Background
With the development of science and technology and the improvement of quality of life, for example, live broadcasting is becoming more and more common, the two-view stereoscopic display technology has become an attractive scientific field.

Therefore, a naked eye two-dimensional (3D) display technology without using external auxiliary tools becomes a research hotspot in the technical field of display.
Currently, most of the naked eye stereoscopic display technologies that have been attempted to be developed based on binocular parallax, mainly the lenticular stereoscopic display technology. The display applying the technology is just a grating type stereoscopic display, which is formed by adding gratings on a flat matrix display panel; the grating can be a slit grating or a cylindrical lens grating; the grating has a light splitting effect, and has an image separating effect when applied to a display.
The principle of the grating type two-view stereo display technology is that a grating is arranged on the light incident side or the light emergent side of a display panel, and due to the light splitting effect of the grating, a single eye of an observer positioned in front of the display panel can only see one column of pixels on the display panel through the grating, for example, the left eye can only see an odd pixel column, and the right eye can only see an even pixel column. In this way, the brain performs a fusion action of two image pairs having horizontal parallax, which are displayed with odd-even pixel columns for the left and right eyes, respectively, to finally form a stereoscopic image having a sense of depth.
Therefore, how to realize better 3D display effect by using the grating type two-view stereoscopic display technology is a current research focus.
