Description
[technical field]
The invention belongs to the three-dimensional stereo display technique field, the present invention relates to a kind of 3D display device and display packing that changes based on electric induced refractive index.
[background technology]
3D, also can be referred to as 3 D stereo or three-dimensional, the 3D imaging technique is different from the two dimensional surface imaging technique, three-dimensional image information is compressed in a two dimensional surface, will certainly make image fault, each pixel true spatial location in the response diagram picture that can not prepare, the 3-D view that two dimensional surface is showed is the light and shade by color, the information such as the size of object are expressed, people by the 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 come each pixel in the subjective judgement two dimensional surface from the distance of human eye, rather than real physical depth.
3-D display is different from two dimension and will ins all sorts of ways and bring the depth perception of vision to the beholder exactly, makes it nature or naturally does not obtain the information of third dimension degree in picture, and this cognitive method is exactly the differences of the false three-dimensionals of true three peacekeepings concerning human eye.So for the three-dimensional imaging technology, the actual physical depth of field in the reduction three-dimensional space is extremely important, is to be also to make human eye can perceive the factor of the most critical of three-dimensional image.
It is at present ubiquitous that to need the dimension display technologies of wearing spectacles be to utilize the principle of binocular parallax to realize, it is also not obvious when wearing spectacles is watched static stereo-picture at short notice, but when watching stereotelevision,, because human eye is in this very natural and not nervous viewed status for a long time, just can feel extremely uncomfortable and very tired.On the other hand because the needs wearing spectacles is watched,, so be only suitable in watching the special occasions such as film, be impossible for advertising display, and the glasses of wearing have filtration to light, so while causing watching figure, light is darker, very bad to eyes.
So at present increasing people hankers after studying the bore hole dimension display technologies, present bore hole dimension display technologies mainly contains optical barrier type (Barrier), lens pillar (Lenticular Lens) technology, points to light source (Directional Backlight), six kinds of MLD dimension display technologies, hologram three-dimensional technology and body dimension display technologies.The advantage of bore hole formula 3D technology maximum is the constraint of having broken away from glasses, but also there are a lot of deficiencies in the aspects such as resolution, visible angle and visual range.
The optical barrier type dimension display technologies has been utilized the parallax barrier that is placed between backlight module and LCD panel, and under the stereo display pattern, in the time of should being presented on liquid crystal display by the image that left eye is seen, opaque striped can block right eye; In like manner, in the time of should being presented on liquid crystal display by the image that right eye is seen, opaque striped can block left eye, by the viewable pictures with left eye and right eye separately, makes the onlooker see the 3D image.The advantage of optical barrier type dimension display technologies be and existing LCD liquid crystal process compatible, therefore on production and cost than the tool advantage, but shortcoming is to adopt the product image resolution of this kind technology and brightness meeting to descend, and visible angle is also restricted.
The principle of lens pillar dimension display technologies is to add the last layer lens pillar in the front of LCDs, make as plane, being positioned on the focal plane of lens of liquid crystal display, the pixel of the image below each post lens is divided into several sub-pixels like this, and lens just can be with each sub-pixel of different direction projections like this., so eyes are watched display screen from different angles, just see different sub-pixels.Although the lens pillar dimension display technologies compare the disparity barrier dimension display technologies, the brightness of image can not reduce, but resolution still can descend, and relevant manufacturing is incompatible with existing LCD liquid crystal process, need investment new equipment and production line, cost is higher.
The method of pointing to the realization of light source (Directional Backlight) 3D technology is by the two groups of LED that arrange in pairs or groups, coordinate rapid-action LCD panel and driving method, allow the 3D content enter beholder's right and left eyes with sortord, produce parallax owing to exchanging image, and then allow human eye experience the 3D 3-D effect.This technology has very large advantage, can both be protected on brightness that 3D shows and resolution, but because still having utilized people's right and left eyes principle of parallax, it make image be processed to form 3-D view in people's brain, so the phenomenons such as tired, dizzy still easily occur after the people is long in the time of watching.
In April, 2009, bore hole 3D technology---the MLD (multi-layer display Multi-level display) after improvement is developed in the declaration of U.S. PureDepth company, this technology can be passed through two overlapping liquid crystal panels of certain intervals, realization in the situation that do not use special eyeglasses, presents the effect of 3D image while watching word and picture.Present technique is owing to only having two liquid crystal panels, so the depth of field of the image that presents is limited, the 3-D display effect is poor, and more liquid crystal panel can reduce the brightness of show image.
The hologram three-dimensional technology utilizes the principle of mirror-reflection mirror image can produce stereoeffect very true to nature, but needing very high spatial light modulator and superfast data handling system aspect dynamic demonstration, these two technical limitation the development of this technology, make it can't well apply in actual life at present.
The body dimension display technologies is different from other stereo display techniques is, it is the 3D technology that really can realize dynamic effect, and it can allow you see that general " suspension " in science fiction movies is in the air three-dimensional perspective image.The body dimension display technologies substantially can be divided at present sweep volume and show that (Swept-Volume Display) and solid bodies show (Solid-Volume Display) two kinds.
hologram three-dimensional technology and body dimension display technologies are compared optical barrier type (Barrier), lens pillar (Lenticular Lens) technology, point to light source (Directional Backlight) dimension display technologies, the picture of each pixel or each pixel is not on same plane, has the real depth of field, so while watching the 3D image, the user can not produce dizzy, the spinoffs such as headache and eye fatigue, and the resolution of screen and brightness can not reduce, vision and the angle of watching the 3D image do not had too large restriction, but because stereoscopic three-dimensional display apparatus is compared common 2D display device structure and is wanted 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 panel, so the Development and Production cost is higher.
