Abstract

The invention discloses a three-dimensional raster and a naked eye three-dimensional display device. The three-dimensional raster comprises a substrate and a raster graphic film fixed to the substrate, wherein the raster graphic film is provided with light-proof shielding parts and light transmitting slit parts, and the light-proof shielding parts and the light transmitting slit parts are arranged in a repeatedly alternated mode; the light transmitting slit parts are used for eliminating the relevance between the light transmitting slit parts and a sub-pixel structure of a plane display device so as to avoid generation of moire fringes. The light transmitting slit parts can eliminate the relevance between the light transmitting slit parts and the sub-pixel structure of the plane display device by modifying the shape of the light transmitting slit parts on the three-dimensional raster, the generation of the moire fringes is avoided, the naked eye three-dimensional display device has the advantages of being high in brightness, free of moire fringes and obvious in three-dimensional effect and the like, and accordingly comfortable sensation of people to watch three-dimensional display images is improved greatly.

Description

technical field

[0001] The invention relates to the technical field of 3D stereoscopic display, in particular to a moiré-free stereoscopic grating and a naked-eye 3D display device. Background technique

[0002] In recent years, three-dimensional display technology has developed rapidly and has become a research hotspot. At present, the glasses-type stereoscopic display has been successfully commercialized and entered the households of ordinary consumers. Whether it is polarized glasses or liquid crystal switch glasses, it can separate the two-way images with a certain parallax very well, so that The viewer can see a stereoscopic image with a greater depth of field. However, since people have to wear stereoscopic glasses in the process of viewing such stereoscopic images, people's viewing habits are greatly limited, and there will be discomfort caused by wearing glasses.

[0003] The naked-eye stereoscopic display technology does not need to wear any glasses. When people w...
