Abstract
The invention provides a full-perspective 3D grating structure used for a liquid crystal screen. The full-perspective 3D grating structure comprises an ITO glass plate and grating strips adhered on the ITO glass plate. The grating strips are annularly arranged on the ITO glass plate with equal intervals. With application of the full-perspective 3D grating structure used for the liquid crystal screen, fixed and consistent phase difference is presented to the naked eyes no matter which perspective direction so that inconsistent images are generated to the left eye and the right eye of people, uniform and consistent 3D images are generated via human brains and the full-perspective 3D effect is realized.
Description
Technical field
The present invention relates to technical field of liquid crystal display, particularly a kind of optical grating construction making liquid crystal display present 3D display effect.
Background technology
3D and three-dimensional picture, belong to virtual three-dimension technology, and 3D technology is a kind of technology by utilizing the computing of computing machine to reach the aspect such as vision, sense of hearing stereoeffect.The mode realizing 3D technology in the market has a variety of, comprise timing method, space law and various 3D optometric technology, for universal 3D technology, be convenient for people to viewing, have also appeared several 3D grating technology to realize bore hole 3D technology, 3D grating technology be generally usage space dividing method to realize 3D technology, make the left eye of people and right eye produce phase differential, see inconsistent image, make brain produce 3D rendering.
Traditional 3D optical grating construction is on ito glass plate, arrange some parallel gratings strips, gratings strips is pasted onto on ito glass plate with diagonal manner and realizes 3D effect, the live width of normal light grizzly bar is 0.02mm, the gradient of gratings strips is 5 °, gap width between adjacent gratings bar is 0.5mm, as shown in Figure 1.Owing to being subject to the restriction of gratings strips structure, traditional 3D optical grating construction can only see 3D effect in the angular field of view that the left and right distance of oblique line is no more than 45 °, up and down or tilt viewing time then 3D effect disappear, the 3D technology at full visual angle cannot be realized.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of optical grating construction that can realize full visual angle 3D technology is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
For a full visual angle 3D optical grating construction for liquid crystal display, the gratings strips comprising ito glass plate and stick on ito glass plate, described gratings strips is set in qually spaced on ito glass plate in an annular manner.
The above-mentioned full visual angle 3D optical grating construction for liquid crystal display, described gratings strips is that the spirality of constant pitch is around structure; Pitch is 0.3 ~ 0.8mm, and the live width of gratings strips is 0.02 ~ 0.1mm.
The above-mentioned full visual angle 3D optical grating construction for liquid crystal display, described gratings strips is cirque structure that is equidistant and that arrange with one heart, and each annular gratings strips is four circular arcs waiting radian by even partition; Gap width between adjacent cylindrical gratings strips is 0.3 ~ 0.8mm, and the live width of gratings strips is 0.02 ~ 0.1mm.
The above-mentioned full visual angle 3D optical grating construction for liquid crystal display, the gap between the adjacent circular arc of described annular gratings strips is 0.02-0.1mm.
The above-mentioned full visual angle 3D optical grating construction for liquid crystal display, described ito glass plate is the ito glass plate that glass resistor is not more than 20 Ω.
The mechanism realizing 3D effect in the present invention is when making incident light beam strikes to eyes, and by light blocking, the light making to incide left eye and incide right eye produces phase differential, forms three-dimensional 3D effect after what left eye was different with right eye are imaged onto brain.So, when designing light blocking, there is the gap making light can enter left eye and right eye, have the stopper of display secret note, but traditional design is linear fashion, people's naked eyes can only be made within the scope of ± 45 ° to produce 3D effect, once break through this angular field of view, because Rectilinear barrier block can not change with position, the light entering people's left eye and right eye will reach unanimity, and 3D effect disappears.The present invention is circular design, no matter from 360 ° of directions up and down, it is all consistent for entering people's left eye with the light barrier of right eye, and the phase differential of generation is also consistent, thus no matter the eyes of people from which direction are looked over, all can present the 3D stereoeffect at the full visual angle of stable and consistent.
