Description
Technical field
The invention belongs to stereo display technique field, especially for bore hole 3D display splicing technologies, the present invention realizes naked
The effect of eye 3D display splicing screens splicing seams reduction.
Background technology
Vision is the primary information resource of objective event outside human perception, is reduced by display device true, clear, straight
The world of sight is the target that people pursue always, and the development of Display Technique is demonstrated by this process vividly：From static state to dynamic,
From black and white to color, from SD to high definition, from plane to solid.
Screen become bigization be Display Technique development inexorable trend, especially stereo display technique, the bigger display of size
The stereoeffect that device is brought is stronger, therefore is more welcome by market.But limited by traditional display technologies, oversize
Display screen all has very big burden in terms of cost and yield, therefore is spliced into super large often through reduced size display screen
Size display screen.
Due to there is no technology to realize, non-boundary is shown, therefore this tiled display, can be existed between screen and screen between physics
Gap, generally higher than 5mm, can cause picture to be split in actually viewing, influence viewing comfort level.In plain splice Display Technique
In, many businesses and institutions have spent substantial amounts of manpower and materials on reduction gap joint, substantially there is both direction：
(1) increase luminescent device above frame, this luminescent device and display picture are realized by rational circuit design
Simultaneous display.
(2) increase a optics above frame, the display picture near frame is projected above frame.
Both the above mode, is required for increasing more complicated circuit, optical design, cost increase is obvious, it is clear that unfavorable
In marketing.
The content of the invention
The two methods used the invention aims to solve existing reduction frame need increase complicated circuit and light path
Structure, causes cost to increase, and there is provided a kind of frame reduction side of bore hole 3D display splicing screens for the problem of being unfavorable for marketing
Method.
The frame method for weakening of bore hole 3D display splicing screens of the present invention has two technical schemes.
First technical scheme：The frame method for weakening of the bore hole 3D display splicing screens, large-sized monitor includes tool
There are the front glass plate and mosaic screen of Grating Film, the front glass plate with Grating Film is arranged on the front of mosaic screen；Mosaic screen
Each two unit screen between have frame；
In a side surface of the front glass plate with Grating Film, prism, the optical axis center of the prism and side are set
The geometric center of frame is in same viewing horizontal level；The width of the drift angle opposite side side ratio frame of prism is big by 30%~
50%, the length of prism and the equal length of frame, it is ensured that during viewing, reflected frame by the refraction action of prism
Light is all transferred to outside visible area, and the light of display picture near frame is refracted into human eye, is realized between two unit screens
Frame weakened by vision, seamless full screen display is presented in whole mosaic screen.
Second technical scheme：The frame method for weakening of the bore hole 3D display splicing screens, large-sized monitor includes tool
There are the front glass plate and mosaic screen of Grating Film, the front glass plate with Grating Film is arranged on the front of mosaic screen；Mosaic screen
Each two unit screen between have frame；
Rhizoma Sparganii lens array is set in a side surface of the front glass plate with Grating Film, the Rhizoma Sparganii lens array is by multiple
Prism is constituted side by side, and the optical axis center of the Rhizoma Sparganii lens array and the geometric center of frame are in same viewing horizontal position
Put；The drift angle opposite side total length of Rhizoma Sparganii lens array is bigger than the width of frame by 30%~50%, the length and frame of Rhizoma Sparganii lens array
Equal length, it is ensured that during viewing, the light that frame reflects all is transferred to by visible area by the refraction action of Rhizoma Sparganii lens array
Outside, the light of display picture near frame is refracted to human eye, realizes that the frame between two unit screens is weakened by vision, it is whole
Seamless full screen display is presented in individual mosaic screen.
Advantages of the present invention：The present invention with other using optical principle reduction frame technology compared with, sharpest edges be processing
Simply, with low cost, it is easy to realize.Because plain splice screen can not be needed for advanced optics, therefore other frame reduction technologies
The optics asked must design very compact, and optical design, requirement on machining accuracy are high, and technology difficulty is very big.And the present invention should
Raster pattern bore hole 3D displays, originally just there is advanced optics before flat-panel monitor, will not increase thickness burden, real
Now also it is more prone to.
The present invention is not by other luminescent devices, it is only necessary to which a light penetrating device of fitting is it is achieved that technique is simple.Three
Prism is conventional optics, and easy for installation, effect is substantially, cheap, is very beneficial to marketing.
Prism used can use the system such as high transmittance resin material PMMA, optical glass, crystal, optical mold glue
Into.
