Description
Technical field
The utility model belongs to the projection display technique field, particularly a kind of flexible bead rear-projection curtain.
Background technology
Splice displaying system has been widely used in a plurality of industry fields as the display platform of different places such as displaying, monitoring, commander, meeting, emulation at present.And rear-projection splicing shows to be the first-selection of spliced display wall by feat of high resolving power, high brightness, seamless spliced display effect.Extensive distribution along with display environment, mode and application scenario; The rear-projection splice displaying system is required, and what cast out is not only in the plane; But requirement can have the more original form of expression; Therefore the projection of shape of for example cylindrical, spherical, arc or the like needs to be equipped with the soft curtain of corresponding flexible projection.
Present existing back projection curtain is divided into two types, promptly hard curtain and soft curtain, and soft curtain normally has the curtain of scattering process, owing to there is not optical texture, the visual angle of soft curtain is generally little, and contrast is lower.And hard curtain is a matrix with glass or organic glass (acrylic) usually, covers with structural sheets such as scattering layer or cylindrical lenses to realize, so owing to have complicated mechanism can realize more satisfactory performance.The hard curtain that adopts beaded glass is also arranged, and the hard curtain of beaded glass has the high and good advantage in visual angle of contrast, is shown extensively by back projection and adopts.Yet as described above, in many application scenarios, need soft curtain construct more original design, need soft curtain have good contrast and wideer visual angle simultaneously again, these be present soft act can't satisfy.Therefore, a kind of soft curtain of rear-projection with better optical property need be provided.
The utility model content
The shortcoming that the fundamental purpose of the utility model is to overcome prior art provides a kind of flexible bead rear-projection curtain with not enough, and this rear-projection curtain can carry out flexible bending, and top bead difficult drop-off, long service life, and gain is high.
The purpose of the utility model realizes through following technical scheme: a kind of flexible bead rear-projection curtain; Comprise flexible substrate, be coated in the light-absorption layer on the flexible substrate and be embedded into equally distributed bead in this light-absorption layer that said bead is the transparent ball of being made by the optical material of certain refractive index.Said bead and flexible substrate join.
Said flexible substrate adopts material flexible, the transmissive visible light to process, for example PVC sheet, PET sheet or PC sheet etc.
Further, said flexible substrate carries out antireflection towards spectators' one side to be handled, and specifically can be anti-reflection and the dazzle processing that disappears, and for example atomizing processing or plating anti-reflection film etc. reflect with minimizing.This flexible substrate plays the effect of supporting with fixing flexible rear-projection curtain; It is the flexible substrate of flexible rear-projection curtain; Because this flexible substrate is flexible, flexible, and the glue-line that covers on it also all is soft, can be covered in fully on the flexible substrate; Therefore, this bead rear-projection curtain also is flexible, flexible.
As preferred version, be provided with photic zone between said flexible substrate and the light-absorption layer, euphotic thickness is confirmed by the refractive index and the radius of bead.This photic zone can improve the gain of rear-projection curtain, also plays the effect of supporting bead simultaneously.In this case, even bead does not contact with the flexible substrate surface, as long as pass light-absorption layer, contact with photic zone, the light that bead penetrates also can see through photic zone, arrives flexible flexible substrate surface.Euphotic thickness can effectively be controlled the transparent aperture of rear-projection curtain, and its thickness can be confirmed according to the refractive index and the radius of bead, can improve the transmitance of rear-projection curtain effectively, improves the gain of rear-projection curtain.
Preferably, said light-absorption layer adopts the colloid of black pressure sensitive adhesive or doping black material.The light-absorption layer role is spurious rays and the absorbing environmental light that absorbs through space between bead, also can support bead, and more excellent selection is a black, and the black light-absorbing layer can effectively be absorbed into the light that is mapped on these zones, improves the contrast of screen.Light-absorption layer can be coated on the photic zone, and keeps soft state, so that bead can pass this layer projected light is transmitted from the screen front through light-absorption layer.
For the protection screen, be coated with layer protective layer on said bead and the light-absorption layer, be specially transparent covering layer, this layer also is used for bead is fixed in the rear-projection curtain, and can improve the transmission of projection ray.Overlayer can be a flat outer surface, can cover other layers above that, and perhaps overlayer also can fit in the profile of bead, fine to influence the optically focused effect of bead.
The utility model compared with prior art has following advantage and beneficial effect:
1, the said rear-projection curtain of the utility model can carry out flexible bending, thereby satisfy various application scenarios through adopting flexible substrate, realizes more how original projection form.
2, in the utility model through photic zone, light-absorption layer, transparent covering layer are set on flexible substrate, can more firm being fitted on the flexible substrate of bead be prevented that bead from coming off, prolong the service time of glass bead screen.
3, in the utility model through between light-absorption layer and flexible substrate, photic zone being set; Can be when bead contact with the flexible substrate surface; The light that bead is penetrated sees through photic zone, arrives flexible flexible substrate surface, improves the transmitance of rear-projection curtain effectively.
