Description
Technical field
The present invention relates to naked eye 3D technology fields, and in particular to a kind of naked eye 3D display system of grating postposition.
Background technique
Existing bore hole 3D display device mainly makes one to generate 3D using the principle of binocular parallax to be felt, i.e., by entering
The optical path for penetrating light is adjusted, and the left eye of people is enable to receive left-eye images, and the right eye of people can receive right-eye image, and
Left-eye images and right-eye image will not mutual crosstalks.The naked eye 3D technology means of mainstream have at present: slit liquid crystal grating, column
Lens are directed toward light source, active backlight.
The bore hole 3D display device of grating postposition utilizes the realization of slit liquid crystal grating technological means, the grating postposition
The specific structure of bore hole 3D display device include display panel and grating veneer, mainly using grating plate washer to left eye shadow
It is blocked as L (or right-eye image R), so that the left eye (or right eye) of user can receive left-eye images L (or right-eye image
R), right-eye image R (or left-eye images L) cannot be received, the effect for enjoying 3D picture is enabled a person to.But whether being benefit
With which kind of naked eye 3D technology means, there is a problem of one it is inevitable, that is, viewing visual angle is small, sees when viewer is in
When seeing in visual angle, the left eye of viewer receives left-eye view, and right eye receives right-eye view, and viewer can watch 3D to scheme
Picture, when viewer is in outside viewing visual angle, the left eye of viewer is likely to be received right-eye view, and right eye is likely to be received left eye
View can not then watch clearly 3D rendering, influence viewing effect.
Due to present naked eye 3D technology also prematurity, the factors such as higher cost are caused, the naked eye 3D of grating postposition is aobvious at present
Showing device mainly applies to small mobile terminals, such as mobile phone, TV etc., and the naked eye 3D display of large-scale grating postposition is filled
It sets and is mainly used for the occasions such as showing, publicize.But in the case where the larger spectators of site area are more, spectators can not be concentrated
When in viewing visual angle, in this case, the client outside viewing visual angle can not then realize 3D effect.In order to allow all spectators
3D effect is all realized, then spectators oneself is needed to be transferred in viewing visual angle, multitude of spectators movement is not only very troublesome, but also very
Hardly possible maintains live order.Therefore, it is highly desirable to change the bore hole 3D display device of grating postposition in occasions such as displaying, publicity
Angle is to guarantee the experience sense of each orientation spectators.
Summary of the invention
For the defects in the prior art, the present invention provides a kind of naked eye 3D display systems of grating postposition, with automatic
