Description
Technical field
The present invention relates to 3D display technique field, particularly relate to a kind of can bore hole viewing 2D/3D picture, the three-dimensional private movie theatre display device of high definition bore hole 3D that is audio-visual and game.
Background technology
As everyone knows, whole world Ge great household appliances manufacturer also actively layout prepare to release the household appliances such as the player of a series of support 3D stereo display and televisor, but due to stereoeffect not good enough, all cannot become the market mainstream, three-dimensional film is outshined othersOne branch of the tree is particularly thriving, and vacant market also brings huge business opportunity.Optical lens has the function of high definition amplifying observation; and its focal length is fixed value after completing; and ensure that its lens do not offset in use as far as possible; all very huge in every profession and trade demand, but also there is rapid wear in optical lens, frangible situation; how to protect lens; make the lens life-span more of a specified duration, the history of 3D stereo display is quite remote, just occurs when 19th century camera work ground zero.Why we can experience stereoscopic vision, because the eyes of the mankind are laterally side by side, between the interval of nearly 60 ~ 70 millimeters, therefore the image that the image seen of left eye and right eye are seen has difference slightly, this difference is called as parallax, brain can be understood the parallax of eyes and uses judgment object distance and produce stereoscopic vision, because stereoscopic vision is based on parallax, therefore the basis of 3D stereo display, parallax to be reappeared to manually exactly, its way is that 2 cameras are simulated eyes side by side, take the photograph that 2 have narrow difference simultaneously, two, left and right is allowed to see different images respectively, use and simulate stereoscopic vision, 3D stereo display technique miscellaneous is developed under this basis, and major technique is the viewings of 3D glasses, and viewing 3D video etc. just can must complete by 3D glasses, how to abandon 3D glasses, it is research theme that bore hole watches 3D video.Observer's evaluation equipment clearly can separate the sight line of right and left eyes, do not need to allow beholder oneself with feeling that adjustment sight line is to catch stereoscopic sensation, therefore most people can adapt to, allow right and left eyes watch different pictures through left and right two stack screen and produce parallax to present stereoscopic picture plane, the use of existing head mounted display adds the load-bearing of human body head, and distance of exit pupil is very little, thus make glasses easily tired, the problems such as dizzy and dizzy will be caused after using, be necessary to develop a kind of reasonable in design, picture element is clear, visual angle is large, the optical lens that cost is low, and overcome human body and watch video for a long time, overcome dizzy high definition bore hole display device, as the research direction of this programme.
Application number is the Chinese invention patent of ZL200910053533.5, disclose a kind of can bore hole viewing three-dimensional display, there is provided left by the LCD video player of high resolving power 640*480 for its screen, the image of right two groups of side by side arrangement or video, screen is the LCD display of 4 inches and 4:3, two pieces of convex lens are placed in player screen front, the diameter of convex lens is 4cm, focal length is 18cm, distance between the optical axis of left convex lens and the optical axis of right convex lens is 6 ~ 7cm, an observer's left side is made by convex lens, right eye sees a left side respectively, right image or video, be exaggerated the visual angle of two, the automatic adjustment of human eye makes the final overlapping connection in the brain of observer of two width images, observer produces the sensation seeing three-dimensional image.
There is following shortcoming in this technology:
1, the LCD display of 4:3 and diameter are the convex lens of 4cm, light shape is not mated, it will be appreciated that the parts beyond screen, affect viewing effect.
2, screen resolution is only 640*480, only adopts single LCD display, and after left and right half-and-half divides equally, resolution reduces by half again, and sharpness is lower, and brightness and contrast are also lower, therefore do not have high-definition effect.
3, the LCD display of 4 inches and the convex lens of focal length 18cm, the screen of beholder's viewing is little, therefore does not have giant-screen viewing effect.
4, the LCD display of 4 inches and diameter are the convex lens of 4cm, and convex lens size is little, and the viewing visual angle of observer is little, so human eye distance of exit pupil is little, need be close to convex lens could watch clear.
5, do not arrange between right lenses and screen every tabula rasa, light can mutually alternately, make picture element uneven.
