Embodiment Construction

[0017] The present invention will be further described through the embodiments below in conjunction with the accompanying drawings.

[0018] Fig. 1 shows that when adopting pre-type grating 1 and matrix display 2 to cooperate to form autostereoscopic display, the schematic diagram of very obvious moiré fringe 3 is formed by the image layer of matrix display and front grating, rear-mounted grating stereo display also can produce Similar moiré fringes. This is formed because the structure of the front or rear grating is relatively close to the period of the pixel structure of the matrix display. The moiré fringes are distributed on the entire display surface, and the number and shape of the moiré fringes change with different viewing distances and viewing angles, which will seriously interfere with the stereoscopic image and affect the observation of the stereoscopic image.

[0019] Diagram A in FIG. 2 represents a common front-type slit grating autostereoscopic display, and di...

Abstract

An open-hole stereo-display device of free Moire fringe type is prepared as combining diffusion screen with 3-D open hole free stereo-display of grating mode then using reflection grating structure light field formed by illuminating preset grating of flat matrix display pattern layer in 3-D open-hole free stereo-display and by reflecting light by said grating to carry out interference in order to eliminate interference of Moire fringe on stereo-image.

Description

1. Technical field [0001] The invention relates to the technical field of naked-eye three-dimensional (3D) stereoscopic display, in particular to a grating-type 3D naked-eye autostereoscopic display device and method without Moire interference fringes. 2. Background technology [0002] Glasses-free three-dimensional (3D) stereoscopic display has developed rapidly in recent years, and it has very attractive application prospects in fields such as virtual reality technology, 3D games, 3D advertisements, aerospace, nuclear technology, and biomolecules. Image display is an important device for human beings to receive external information in information transmission. The three-dimensional image display has the characteristics of large amount of information and can reproduce all the three-dimensional information of the actual scene, so that the viewer can directly see the objects in the image from the display. The distance, depth, so viewers can get more comprehensive and intuitiv...
