Description
Technical field
The utility model relates to 3D stereo display technique field, relates in particular to a kind of raster graphic film without Moire fringe, 3 D grating and bore hole 3D display device.
Background technology
In recent years, three-dimensional stereo display technique development rapidly, becomes the focus of people's research.At present, eyeglass stereoscopic display is successfully commercially produced, entered ordinary consumer family, no matter be polaroid glasses, or liquid crystal shutter glasses can well be separated the two-way image with certain parallax, thereby make beholder can see the stereo-picture with the larger depth of field.Yet, because people are in watching the process of this stereo-picture, must wear anaglyph spectacles, greatly limit people's the custom of watching, and had the discomfort that wearing spectacles brings.
Bore hole stereo display technique does not need to wear any glasses, and people are when watching stereotelevision, and eyes are unrestricted, has improved degree of freedom and the comfort level of watching in process.At present, common naked-eye stereoscopic display is mainly raster pattern naked-eye stereoscopic display, mainly 2D flat-panel screens and grating (also claiming 3 D grating) two parts, consists of.Grating mainly contains cylindrical grating and two kinds of modes of slit grating.Conventionally grating is arranged and is formed with planar linear by a plurality of structures and the identical raster unit of performance, and grating can be slit grating or post mirror, and corresponding raster unit is slit or lens pillar unit.Each raster unit with the perpendicular direction of its arrangement on light is not played to plus lens effect; In its orientation, be equivalent to plus lens and play optically focused imaging.This characteristic of grating makes it to image, have the effectiveness of " compression " and " isolation ".Grating divides the optical principle of picture, is to process by grating pair image, relends and helps original screen panel and make plane picture have stereoscopic sensation intuitively.By scenery being recorded to one group of left and right scape plane picture, and allow two only to see respectively corresponding picture, the relative parallax existing between two plane pictures of left and right will cause eyes adjustment to focus on angle, just, as seen true view, make people produce three-dimensional stereoscopic visual sense.
The display screen of 2D flat-panel screens is mainly comprised of two-dimensional array, and each region, sub-pixel edge is lightproof area, and when backlight irradiates display screen, we claim that lightproof area is black matrix.When display screen is illuminated by backlight, the black matrix that display screen produces is the two-dimension light field structural interaction that two-dimension light field structure and grating are illuminated generation, thereby produces so-called Moire fringe, has had a strong impact on vision viewing effect.
In order to reduce the impact of even eliminating Moire fringe, prior art has proposed some and has eliminated the method for Moire fringe, as a kind of method of destroying optical grating construction light field proposing in the China Patent Publication No. document that is CN101000406A is eliminated the scheme of Moire fringe, in this scheme, by increasing diffuser screen, eliminate Moire fringe, but owing to having increased diffuser screen at image emissions end, light scattering effect due to diffuser screen, had a strong impact on the quality of picture imaging, although solved the impact of Moire fringe, can not obtain effective stereo-picture.China Patent Publication No. is also to have proposed a kind of moire-free three-dimensional display device in the document of CN101122684A, in this scheme, by the angle between design grating and liquid crystal display Pixel arrangement, make the little degree that cannot differentiate to human eye of width of the Moire fringe that produces between grating and display screen, with this, eliminate and reduce the Moire fringe producing between grating and display screen.But grating and Pixel arrangement angle are calculated in simple passing through, and make grating when arranging by certain angle, have ignored the crosstalk phenomenon of interlacing sub-pixel, can cause the reduction of finally watching stereo image quality equally
In view of this, prior art has yet to be improved and developed.
