Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the present invention is further elaborated, but the implementation of the present invention is not limited to this.
Embodiment 1
Shown in 2, for the principle schematic of the seam device embodiment 1 that disappears of the present invention.Shown in Figure 3, for the structural representation of the seam device embodiment 1 that disappears of the present invention.
As shown in Figure 2 and Figure 3, the seam device that disappears of this enforcement 1, including being located at first optical module 3 of viewing area 1 dead ahead of display screen and being located at rim area 2 dead ahead of described display screen second optical module 4 corresponding with the first optical module 3；
Equal and rim area 2 the width of the width of first optical module the 3, second optical module 4 is consistent, and first optical module the 3, second optical module 4 all includes multiple first deviation part 5；
First deviation part 5 of first optical module the 3, second optical module 4 is all along the direction arrangement vertical with the intersection of described viewing area and described rim area, and the beam projecting face of each described deviation part is cylinder.
Wherein, the front of all corresponding display screen of viewing area 1 dead ahead and rim area 2 dead ahead, those of ordinary skill in the art is to be understood that it refers to when using display screen (or giant-screen of multiple display screen composition), this side of beholder.
First optical module 3 is provided in the marginal portion of viewing area 1.
First optical module 3 is corresponding with the second optical module 4 includes that structure is corresponding and position is corresponding, wherein, position correspondence refer to the first optical module 1 deviation part refraction after outgoing light need can enter into a correspondence position the second optical module 4 deviation part in, structure correspondence refers to that the structure of two the first deviation parts 5 (namely position corresponding two the first deviation parts 5) that same light beam is reflected is essentially identical, or identical.
The width of the first deviation part 5 in same optical module (can be the first optical module 3 can also be the second optical module 4) is different, thus can pass through the width realization adjusting the first deviation part 5 control to the amount of light of each first deviation part 5, in order to make light intensity seamlessly transit, generally require that the width of the first deviation part 5 is according to the gradual change that puts in order, and be according to away from rim area to pressing close to the order that rim area is increasing, this is because according to from away from rim area to pressing close to the order that rim area is increasing, both the position light intensity change away from rim area will not have been made too obvious, also ensure that there is enough brightness rim area, achieve seamlessly transitting from viewing area to the district that broadens.
The quantity of the first deviation part 5 is together decided on being actually needed by processing technique level, and in certain scope, the quantity of the first deviation part 5 is more many, and intensity transition is generally also more smooth.
Adopt the above-mentioned seam device that disappears of the present invention, the light of relevant position, viewing area is by after each first deviation part 5 deviation of the first optical module 3, after each second deviation part 5 deviation again arriving the second corresponding optical module 4, exit face from each second deviation part 5 of the second optical module 4, owing to the first optical module 3 and the second optical module 4 all include multiple first deviation part 5, can by adjusting the control that the width of each first deviation part 5 realizes the amount of light of each first deviation part 5, thus realizing seamlessly transitting between rim area emergent ray and viewing area emergent ray, strengthen display effect.
Wherein in an embodiment, the directrix equation of the cylinder that the beam projecting face of above-mentioned each first deviation part 5 is corresponding is all identical, adopt the scheme in the present embodiment, will by same focus by the light of each first deviation part 5 of the first optical module 3, after each first deviation part 5 deviation again arriving the second corresponding optical module 4, from exit face, so, as long as the distance between the first optical module 3 and the second optical module 4 is about deviation part 5 two focus length, avoid the distance repeatedly adjusted between the first optical module 3 and the second optical module 4, manufacturing cost can be reduced.

Being parallel to each other of the plane that the beam projecting face of each described deviation part is corresponding；
Or
In described 3rd optical module, the difference of adjacent second deviation part width becomes arithmetic progression, and in described 4th optical module, the difference of adjacent second deviation part width becomes arithmetic progression.
8. the seam device that disappears according to claim 6, it is characterized in that, accounting for the ratio of the second width less than or equal to 10% farthest away from the width of the second deviation part of described rim area in described 3rd optical module, the width pressing close to the second deviation part of described contiguous concatenation rim area most accounts for the ratio of described second width less than or equal to 42%；Described 4th optical module accounts for the ratio of described second width less than or equal to 10% farthest away from the width of the deviation part of described viewing area, the width pressing close to most the deviation part of described viewing area accounts for the ratio of described second width less than or equal to 42%, wherein, described second width is equal to the width number divided by the second deviation part in described 3rd optical module of described three optical modules.
9. according to the seam device that disappears one of claim 6 to 8 Suo Shu, it is characterized in that, described 3rd optical module and described 4th optical module also include the second non-deviation part of multiple and described second deviation part cross arrangement, the second deviation part integrator that described second non-deviation part is adjacent with this second non-deviation part.
10. a seamless tiled display equipment, it is characterized in that, including the seam device that disappears described in any one of claim 6 to 9, also include display screen described at least two, described display screen includes viewing area and rim area respectively, and the rim area of adjacent described display screen forms piece；Dead ahead in the viewing area on the both sides of described piece is respectively mounted described in one to disappear the 3rd optical module in seam device, and disappear described in installing one at the dead ahead of described piece the 4th optical module in seam device.
