Raster graphic film, three-dimensional optical grating and naked eye 3D display device

Abstract

The invention discloses a raster graphic film, a three-dimensional optical grating and a naked eye 3D display device. Multiple sets of light-transmitting area repetitive units are periodically arranged on the raster graphic film in the transverse direction. Each light-transmitting area repetitive unit comprises multiple lines of light-transmitting areas which are sequentially arranged. The intervals between the adjacent light-transmitting areas on the raster graphic film are equal. The light-transmitting areas are arranged in an inclined mode by a preset angle in the longitudinal direction of the raster graphic film. Each light-transmitting area comprises a plurality of light-transmitting structures which are connected together and have the same shape and size. A preset distance exists between the vertical arrangement positions of every two adjacent lines of light-transmitting areas in the same light-transmitting area repetitive unit. By means of the light-transmitting areas which are periodically arranged in a staggered mode, the phenomenon of moire fringes formed between a black matrix and an optical grating of a 2D display screen is thoroughly avoided through the naked eye 3D display device, the three-dimensional image quality of the naked eye 3D display device is higher, and the effect of the naked eye 3D display device is better.

Description

technical field [0001] The invention relates to the technical field of 3D stereoscopic display, in particular to a moiré-free grating graphic film, a three-dimensional 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 we...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a grating graphic film, a three-dimensional grating and a naked-eye 3D display device for the defects of the above-mentioned prior art, so as to solve the problem of moire fringes existing in the naked-eye 3D stereoscopic display in the prior art that affects visual viewing. The problem of the effect, and the problem that the stereoscopic image quality is not high and the effect is not good in the existing method for overcoming Moiré fringes
