Description

General stereo-picture synthetic method based on the pole mirror grating LCD freedom stereoscopic display device
Technical field
The present invention relates to a kind of general stereo-picture synthetic method based on the pole mirror grating LCD freedom stereoscopic display device.
Background technology
Continuous development along with Display Technique, people have developed various need not by auxiliary tools of looking such as anaglyph spectacleses, and directly just can watch the free 3 D display technology of stereo-picture with bore hole, mainly comprise column mirror grating stereo demonstration, slit grating stereo display, holographic three-dimensional demonstration and the demonstration of body 3 D stereo etc.In numerous free 3 D display technologies, because of column mirror grating is easy to processing, stereoscopic visual effect is outstanding, and become current comparatively common free 3 D display technology based on the free 3 D display technology of column mirror grating.
3 D grating generally is attached to stereo-picture or display screen outside, and people just can utilize the refraction principle of light and see stereo-picture with bore hole like this.3 D grating can be divided into three major types substantially: slit grating, prismatic mirror grating and dot matrix grating.Slit grating is commonly called as the black light grid, and its image-forming principle is the pinhole imaging system principle, thereby it is that interval process black lines constitute black non transparent lines and transparent gap length structure arranged on transparent film.The slit grating imaging is clear, can not produce a dizzy eye effect basically, but it must have auxiliary background light source, is not having under the situation of light source, will be as dark as a stack of black cats and can't see any stereoeffect.Column mirror grating is commonly called as white raster, and its image-forming principle is the convex lens image-forming principle, and it is formed by the post lens arrangement of a rule.No matter have or not background light source, can see good stereoeffect by column mirror grating, stereoeffect is perfect more under the situation of light source of having powerful connections certainly.In addition, under the prerequisite that production technology improves constantly at present, the dizzy eye effect of column mirror grating also can be avoided.The dot matrix grating is called holographic formula dot matrix grating again, and its image-forming principle is the convex lens image-forming principle, and its surface is made up of bulbous protrusion one by one.Because the dot matrix grating is rarely found, and the slit grating stereoeffect is added column mirror grating and is easy to processing not as column mirror grating, is therefore greatly developed and popularizes based on the free stereo display equipment of column mirror grating.
