Abstract
A multiple-screen-spliced seamless display screen comprises at least at least two display units which are mutually spliced. Image processing modules same in size are overlaid on the surface of all the display units. The image processing modules can be Fresnel lenses, cylindrical lenses, amplifying lenses or optical lenses. Optical processing modules are additionally overlaid on the image processing modules. The optical processing modules can be anti-dazzle glass, organic glass, acrylic plates, resin materials or anti-scratch lenses. The display units, the image processing modules and the optical processing modules are wrapped by fixing modules and are connected and fixed. The multiple-screen-spliced seamless display screen really achieves seamless splicing of the display units, makes the overall performance of images displayed by the display screen just fine, effectively prevents dislocation of images and characters generated when precision graphics are displayed and eliminates the visual protrusion sense.
Description
Technical field
The utility model relates to large-screen splicing display technique field, relates in particular to a kind of seamless display screen of multi-screen splicing.
Background technology
At present, known large-screen splicing display technique usually adopts the independent display units such as LCD, DLP, PDP to carry out simple physical and is spliced, two adjacent concatenation units adopt alignment, fashion of extrusion to realize the physics splicing, because display unit is all simple individual packages, can form larger piece after being spliced into giant-screen, the dislocation that when showing accurate picture and text, can produce picture and word because picture isolates, greatly affect image display effect and full frame viewing effect.
At present both at home and abroad the processing of this kind of piece had to three kinds: the first is to add the LED dot matrix at the display unit frame, this kind of method when display text archives or purer color picture the effect bad luck and cost higher, be difficult for volume production; The second is to reach refraction effect by adhering to curved glass, but can affect picture effect and increase the black surround effect.The third is to cover one deck image processing module at display unit, make light reflect to evade the physics piece, solved well the deficiency of first two connecting method, a kind of multi-screen connected welding system based on seamless display that for example the Chinese patent application application number is 201310106912.2, it is characterized in that, comprise signal source (1), signal processing unit (2), the screen splicing wall formed by two or more display units (3) splicing, two or more optical modules (4) and stuck-module (5), wherein, the corresponding display unit (3) that covers of each optical module (4), described optical module (4) is fixing by stuck-module (5) with display unit (3), the distance of every two optical modules (4) splicing place equals the distance of corresponding two display units (3) splicing place, and the position of two splicings place is consistent, the edge chamfer of described optical module (4) is angle setting in 45 °-60 °.This technical scheme is the third described method, but the defect of its technical scheme is to be set to 45 ° ~ 60 ° by the edge chamfer of optical module (4), refracted ray can not be filled the physics piece fully, when closely watching, the physics piece can not be evaded fully, and just simply utilizing optical module to carry out simple the amplification to image fills, whole display frame visually has the projection sense in addition, affects the display effect of whole picture, haves much room for improvement.
Summary of the invention
The utility model is for the deficiencies in the prior art, a kind of physics piece that can make light fill display unit fully is provided, eliminate the sense of vision projection, realize the really seamless spliced of giant-screen, make the picture display effect seamless display screen of the multi-screen splicing of clear and smooth more.
Key problem in technology of the present utility model is: set up on the basis of existing technology an optical processing module, image after the optical processing module is amplified image processing module is revised, eliminate the impact of ambient light on image processing module, make distribution of light more even, strengthen picture contrast and image sharpness, thereby the projection sense occurred while effectively eliminating picture disply, and can play protective action to image processing module and display unit.Its concrete technical scheme is: a kind of seamless display screen of multi-screen splicing, comprise at least two mutual spliced display units, each display unit surface is superimposed with the image processing module of formed objects, described image processing module is Fresnel mirror, cylindrical mirror, magnifier or optical lens, it is characterized in that the another superimposition of image processing module has the optical processing module, described optical processing module is glare proof glass, organic glass, acrylic board, resin material or anti-scratch eyeglass, described display unit, image processing module and optical processing module are enclosed with stuck-module and are connected and fixed.
As further improvement of the utility model, described image processing module edge chamfer is set to 90 °.This kind of improvement is also another key problem in technology of the utility model, the display unit throw light is to the surrounding scattering, the outside scattering of display unit physics frame dull thread, for the physics frame that the makes display unit light by viewing area moves on it, utilized scattered beam to change the principle of radiation direction by image processing module, the image processing module that unified specification is set changes optical direction, the reason that 90 ° of chamferings must be set at the image processing module edge is that scattered beam can change direction after passing through the optical processing module arbitrarily, to all the winds refraction, if 45 ° ~ 60 ° chamferings are set, there is space during the splicing of adjacent image processing module, some zonal ray after image processing module, reflect less than, make refracted ray can't fill the physics piece of display unit fully, visually can't eliminate the piece between each display unit fully.And the image processing module edge chamfer is set to 90 ° of not only assurances and display unit and absolute the flushing of optical processing module in splicing, and incident light can be filled the physics piece of whole display unit fully in refracting process, visually eliminate the piece between each display unit fully, realize seamless display truly.
As preferably, the described display unit of described display unit is LCD tiled display equipment, PDP tiled display equipment, DLP rear-projection tiled display equipment, LED rear-projection tiled display equipment or projector's tiled display equipment.
The beneficial effects of the utility model: the utility model has really been realized between display unit seamless spliced, the integral image performance that display screen is shown is better, the situation of the picture produced while effectively preventing from showing accurate picture and text and the dislocation of word, and eliminate visual projection sense.
