Abstract
This invention discloses one 3D free column display device based on hole gap plane grating, wherein, the device comprises plane display screen and hole gap plane grating; the hole gap plane grating is for front and back types; hole plane grating is formed on the opaque plane process with basic function similar to normal seam grating to process division in plane display screen to realize 3D free space display.
Description
One, technical field
The present invention relates to three-dimensional (3D) stereo display technique field, more particularly, the present invention relates to 3D bore hole free 3 D display technology field.
Two, background technology
Realize that it is human long-term dream that 3D shows, along with the development of 3D bore hole free 3 D display technology, this dream is progressively realizing.Wherein the slit grating formula 3D auto-stereoscopic display based on binocular parallax and grating beam splitting principle has good stereo display characteristic, is a kind of important bore hole 3D auto-stereoscopic display, and it forms by installing slit grating additional on two dimension (2D) flat-panel screens.2D two-way array display comprises LCD LCD, plasma display PDP, Field Emission Display FED, display of organic electroluminescence OLED etc.Grating can be forward type, promptly between backlight and flat-faced screen; Also can be rear-mounted, promptly be positioned at flat-faced screen towards spectators this one side outside.Conventional slit grating is to form processing secret note on the transparent substrates such as glass or organic glass, or is bonded on the transparent substrates after stamping secret note on the transparent film again and constitutes, as shown in Figure 1.The transmissive slit part of conventional slit grating is because the existence of substrate, reflection of light and absorption are arranged, thereby cause the brightness and contrast of display image not high, crosstalking of horizontal parallax figure is serious, and there is a Moire fringe that produces by between the reflected light of transmissive slit part and the matrix display pixel light, these Moire fringe stereoscopic image can produce serious disturbance, when serious even can't make the people see stereo-picture clearly.These defective effects of slit grating formula 3D auto-stereoscopic display its apply, remain to be improved.
Three, summary of the invention
For this reason, the present invention proposes a kind of 3D auto-stereoscopic display device based on porous flat grating, as shown in Figure 2, this device is made of flat-faced screen, porous flat grating, and porous flat grating can be forward type, promptly between backlight and flat-faced screen, shown in accompanying drawing 2 (a), also can be rear-mounted, promptly be positioned at flat-faced screen towards spectators this one side outside, shown in accompanying drawing 2 (b).Porous flat grating is to process hole to form on opaque flat board, and its basic role and conventional slit grating are similar, can carry out beam split to the disparity map that shows on the flat-faced screen, thereby realizes that the 3D free stereo shows.The printing opacity hole of porous flat grating is equivalent to the transmissive slit part of conventional slit grating, and is the same with conventional slit grating, and its size and shape are determined by the pixel size of flat-faced screen and shape and the 3D stereo display effect that will reach.
The outstanding advantage of this contrive equipment is the complete printing opacity of printing opacity hole part of porous flat grating, reflective and the extinction that does not have the transmissive slit part of conventional grating, thereby improved the brightness and contrast of display image, reduced crosstalking of horizontal parallax figure, eliminate in the conventional slit grating formula 3D three-dimensional display Moire fringe that produces by between the reflected light of transmissive slit part and the matrix display pixel light, improved stereo image quality.The present invention will promote applying of raster pattern 3D bore hole auto-stereoscopic display.
The present invention is the same with conventional slit grating formula 3D auto-stereoscopic display, realizes that according to binocular parallax and grating beam splitting principle 3D bore hole free stereo shows.
Device of the present invention constitutes raster pattern 3D auto-stereoscopic display with associated driver circuitry and other auxiliary accessories, is used for 3D stereotelevision, the three-dimensional computer monitor of 3D, the demonstration of 3D stereo mobile telephone and other 3D stereo display field.
