Abstract

The invention discloses a naked eye three-dimensional display system and a refractive index adjusting device and belongs to the technical field of display.The system comprises the refractive index adjusting device, an image device and a bearing screen, wherein the refractive index adjusting device comprises a permeation area, the image device is used for projecting at least two related images to different positions of the permeation area of the refractive index adjusting device at the same time, and the refractive index adjusting device is used for changing the image distance between the at least two related images by adjusting the refractive indexes of different positions and projecting the at least two related images with image distance changed onto the bearing screen.The refractive index adjusting device is adopted for adjusting the refractive indexes of the at least two related images projected at different positions of the permeation area so as to adjust the image distance between the at least two related images, and projecting the at least two related images onto the bearing screen.The problem that in relates techniques, display of two related images is obviously inconsistent is solved, and a good naked eye three-dimensional display effect is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a naked-eye three-dimensional display system and a refractive index adjustment device. Background technique [0002] Naked-eye three-dimensional (English: three-dimensiona; abbreviation: 3D) display technology is a technology that allows users to observe 3D graphics without wearing 3D glasses. Currently, naked-eye 3D technologies include: slit liquid crystal grating technology, cylindrical prism technology, pointing light source technology and multi-layer display (English: multi-layer display; MLD for short) technology. [0003] In the related art, there is a naked-eye three-dimensional display system using MLD technology. The system includes two liquid crystal displays (English: Liquid Crystal Display; LCD for short). The two LCDs are overlapped and display two associated images (associated images). The images can be displayed on different image distances to achieve a stereosc...
