Description
Technical field
The present invention relates to stereo display technique field, more particularly to a kind of 3 d display device.
Background technology
With the development of Display Technique, people can not be satisfied with the plane of two-dimentional (Two Dimensions, 2D) and show
Diagram picture, and be the need for the 3 d display device of three-dimensional (Three Dimensions, 3D) be provided with depth perception, more
Comprehensive information.The ultimate principle of three-dimensional imaging, including：
There is a certain distance between left eye and right eye, therefore the viewing angle of two be slightly different when scenery is watched,
The difference of the viewing angle causes left eye to see that left image, right eye see right image, and left image is differed with right image, Jing brains
Stereoperception will be produced after synthesis, the purpose for viewing and admiring 3 D stereo display image is reached.
The existing scheme for realizing viewing and admiring 3 D stereo display image, including：
First, people simultaneously shoot film to same scenery with the apish left eye of two video cameras and right eye first, then
Two films are synchronously shown on one screen, now beholder needs to wear a polarised light glasses, it is possible to view and admire
3 D stereo display image；
2nd, beholder wears shutter glasses, is scanned coming across the screen of display in left 3 D stereo display image
When upper, the i.e. left eyeglass of the left electronic liquid-crystal shutters of shutter glasses was controlled for opening, the right electronic liquid-crystal shutters of the shutter glasses i.e. right side
Eyeglass is closed mode, conversely, when on the screen that right 3 D stereo display image is scanned come across display, controlling shutter
The right electronic liquid-crystal shutters of glasses are that right eyeglass is opening, and the left electronic liquid-crystal shutters of shutter glasses are left eyeglass to close shape
State, so that beholder can see left or right 3 D stereo display image, reaches the purpose for viewing and admiring 3 D stereo display image；
3rd, beholder is allowed to wear the glasses of helmet-type, the left eyeglass and right eyeglass of the glasses are respectively a miniature displays
Device, left eyeglass show left-eye image, and right eyeglass shows eye image, therefore can make one to feel as into one and have relief
Among virtual environment.
In sum, existing 3 d display device do not possess can show in vertical direction Glassless three-dimensional stand
Body display image, can also show the function of the 3 D stereo display image of Glassless in the horizontal direction, it is impossible to realize seeing
The person of seeing can reach the purpose for viewing and admiring 3 D stereo display image by bore hole.
