Description

Based on the 3D display device of electroluminescent refraction index changing
[technical field]
The invention belongs to three-dimensional stereo display technique field, the present invention relates to a kind of 3D display device based on electroluminescent refraction index changing.
[background technology]
3D, also 3 D stereo or three-dimensional can be referred to as, 3D imaging technique is different from two dimensional surface imaging technique, three-dimensional image information is compressed in a two dimensional surface, image fault will certainly be made, each pixel true spatial location in the response diagram picture that can not prepare, the 3-D view that two dimensional surface is shown is the light and shade by color, the information such as the size of object are expressed, people by psychological hint effect again in conjunction with the light and shade of the color in two dimensional surface, the information such as the size of object carry out the distance of each pixel in subjective judgement two dimensional surface from human eye, instead of real physical depth.
3-D display is different from two dimension and brings the depth perception of vision exactly by various method to beholder, makes it nature or naturally does not obtain the information of third dimension in picture, and this cognitive method is concerning the differences human eye being exactly the false three-dimensionals of true three peacekeepings.So for three-dimensional imaging technology, the actual physical depth of field in reduction three-dimensional space is extremely important, is also be the factor enabling human eye perceive the most critical of three-dimensional image.
The ubiquitous dimension display technologies of wearing spectacles that needs utilizes the principle of binocular parallax to realize at present, it is not obvious when wearing spectacles watches static stereo-picture at short notice, but when watching stereotelevision, because human eye is in this very unnatural and viewed status of anxiety for a long time, just can feel extremely uncomfortable and very tired.On the other hand due to the viewing of needs wearing spectacles, so be suitable only for the special occasions such as viewing film, be impossible for advertising display, and the glasses worn have filtration to light, so dark when causing viewing figure, very bad to eyes.
So increasing people hankers after research naked eye three-dimensional display technique at present, current naked eye three-dimensional display technique mainly contains optical barrier type (Barrier), lens pillar (LenticularLens) technology, points to light source (DirectionalBacklight), MLD dimension display technologies, hologram three-dimensional technology and body dimension display technologies six kinds.The maximum advantage of bore hole formula 3D technology has broken away from the constraint of glasses, but the aspects such as resolution, visible angle and visual range also exist a lot of deficiency.
Optical barrier type dimension display technologies make use of the parallax barrier be placed between backlight module and LCD, and under stereoscopic display mode, when the image should seen by left eye is presented on liquid crystal display, opaque striped can block right eye; In like manner, when the image should seen by right eye is presented on liquid crystal display, opaque striped can block left eye, by by the viewable pictures of left eye and right eye separately, makes onlooker see 3D image.The advantage of optical barrier type dimension display technologies be and existing LCD liquid crystal process compatible, on production and cost, therefore comparatively have an advantage, but shortcoming adopts the product image resolution of this kind of technology and brightness to decline, and visible angle is also restricted.
The principle of lens pillar dimension display technologies is before LCDs, add last layer lens pillar, what make liquid crystal display is positioned on the focal plane of lens as plane, the pixel of the image like this below each post lens is divided into several sub-pixel, such lens just can with different direction projections each sub-pixel.So eyes, from different angles viewing display screen, just see different sub-pixels.Although lens pillar dimension display technologies compare disparity barrier dimension display technologies, the brightness of image can not reduce, but resolution still can decline, and relevant manufacture is incompatible with existing LCD liquid crystal process, need the new equipment of investment and production line, cost is higher.
The method pointing to the realization of light source (DirectionalBacklight) 3D technology is by the two groups of LED that arrange in pairs or groups, coordinate rapid-action LCD and driving method, 3D content is allowed to enter the right and left eyes of beholder with sortord, produce parallax owing to exchanging image, and then allow human eye experience 3D 3-D effect.This technology has very large advantage, the brightness and resolution of 3D display can both be protected, but the right and left eyes principle of parallax that still make use of people due to it is processed to form 3-D view to make image in the brain of people, so still easily there is fatigue in people after the time of viewing is longer, the phenomenons such as dizziness.
In April, 2009, PureDepth company of the U.S. announces bore hole 3D technology---the MLD (multi-layerdisplay Multi-level display) after developing improvement, this technology can by two pieces of liquid crystal panels of certain intervals overlap, realize when not using special eyeglasses, when viewing word and picture present the effect of 3D image.This technology is owing to only having two pieces of liquid crystal panels, so the depth of field of the image presented is limited, 3-D display effect is poor, and more liquid crystal panel can reduce the brightness of show image.
Hologram three-dimensional technology utilizes the principle of mirror-reflection mirror image can produce stereoeffect very true to nature, but in Dynamic Announce, need very high spatial light modulator and superfast data handling system, the development of this technology of these two technical limitation, makes it can't well to apply in actual life at present.
Body dimension display technologies then with other stereo display techniques unlike, it is the 3D technology that really can realize dynamic effect, it you can be allowed to see in science fiction movies, general " suspension " is at three-dimensional perspective image in the air.Body dimension display technologies can be divided into sweep volume to show (Swept-VolumeDisplay) and solid bodies display (Solid-VolumeDisplay) two kinds at present substantially.
Hologram three-dimensional technology and body dimension display technologies compare optical barrier type (Barrier), lens pillar (LenticularLens) technology, point to light source (DirectionalBacklight) dimension display technologies, the picture of each pixel or each pixel is not in same plane, there is the real depth of field, so during viewing 3D image, user can not produce dizzy, the spinoffs such as headache and eye fatigue, and the resolution of screen and brightness can not reduce, too large restriction is not had to the vision and angle of watching 3D image, but compare common 2D display device structure due to stereoscopic three-dimensional display apparatus and want complicated a lot, and due to the factor of structure, so volume is larger, cost is higher, and it is not compatible with existing LCD, so Development and Production cost is higher.
