General naked-eye 3D stereoscopic image display techniques are mainly classified into two types, one is Lenticular Lens (lenticulars) and the other is Parallax Barrier (Parallax Barrier). The lenticular lens technology mainly uses the focusing and light refraction technologies of the lenticular lens to change the light traveling direction to split the light, so as to generate the parallax effect on the image information, and combine the two images into a stereoscopic effect through the brain of the viewer. The parallax barrier type mainly utilizes the transparent and opaque (black) linear stripes to limit the light traveling direction, so as to generate the parallax effect on the image information, and the two images are synthesized into the stereoscopic effect through the brain of the viewer.
However, both of these stereoscopic image display technologies have the same two arrangements and overlap, which easily causes "Moire" (Moire Pattern) on the stereoscopic image screen, and thus the visual quality is seriously affected. At present, manufacturers want to reduce or eliminate the generation of moire fringes by changing the internal structure arrangement mode, take a lenticular lens type stereoscopic display as an example, some lenses are obliquely arranged to be different from the traditional vertical or horizontal arrangement mode, but the shape of a lower substrate is changed in such a mode, and then a plurality of substrates are assembled with each other, and cannot be smoothly arranged in a common rectangular shell, and a shell with the same shape needs to be additionally customized, or the assembled substrate is cut to conform to the shape of the shell, so that the waste of the LED arrangement space on the substrate is caused; in some displays, the shape of the lens is changed, but it is necessary to confirm whether the parameters of the refraction direction, brightness, etc. of the light meet the requirements through many experiments, and the manufacturing cost is increased greatly, which is inconvenient.
