Abstract
The invention discloses a novel high-fog high-brightness diffusion plate, which comprises a diffusion plate layer, a bonding layer and a diffusion film layer, wherein the diffusion film layer is attached to the diffusion plate layer via the bonding layer. Cost of the diffusion plate is further reduced, and through attaching the diffusion film on the diffusion plate, functions of the diffusion film and the diffusion plate can be met at the same time, and purposes of atomizing lamp shadow, enhancing the brightness and reducing cost (material cost and manual assembly cost) are achieved.
Description
Technical field
The present invention relates to a kind of novel high fog high briliancy diffuser plate.
Background technology
The ingredient that diffuser plate is important in straight-down negative DLED backlight module, its effect is that the light that LB sends is focused on front by low-angle bright dipping, promotes briliancy, is atomized lamp shadow effect simultaneously.Along with the development of industry, more and more higher to the requirement of subjective picture, brightness and low cost, this just has higher requirement to optical film material.Adopt a diffusion barrier to add the framework of a diffuser plate in current DLED application, meet the requirement of subjectivity, brightness and low cost with this.
Summary of the invention
In order to solve the problem, the invention provides a kind of novel high fog high briliancy diffuser plate.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of novel high fog high briliancy diffuser plate, comprises diffusion flaggy, bonding coat, Diffusion barrier layer, and this Diffusion barrier layer is attached on diffusion flaggy by bonding coat.
Described bonding coat is UV glue.
Described diffusion flaggy has the incidence surface and exiting surface that are oppositely arranged; Wherein, described incidence surface has multiple incident area vertically opposite with light source, described incident area has multiple first concave point and/or multiple first salient point; Described exiting surface have multiple second concave point and/or multiple second salient point; The aperture area of described first concave point and described second concave point is π (D/2) 2; The base area of described first salient point and described second salient point is π (D/2) 2; π is circular constant, and D value is 5 ~ 300 μm.
Described diffusion flaggy comprises main body flaggy and thermoplastic resin; Thermoplastic resin is attached to upper surface and/or the lower surface of main body flaggy; The material of main body flaggy is PS; The material of thermoplastic resin is the one in PMMA, PO, PP, PE and MS; In main body flaggy and thermoplastic resin, also infiltration has optics master batch.
The invention has the beneficial effects as follows: diffuser plate of the present invention reduces costs further, the novel diffuser plate on diffuser plate is fitted in by diffusion barrier, meet the function of diffusion barrier and diffuser plate, the object reach atomization lamp shadow, promoting brightness, reduce costs (material cost and man-made assembly cost) simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is diagrammatic cross-section of the present invention.
Embodiment
With reference to shown in Fig. 1, be one of the present invention novel high fog high briliancy diffuser plate, comprise diffusion flaggy 10, bonding coat 20, Diffusion barrier layer 30, this Diffusion barrier layer 10 is attached on diffusion flaggy 30 by bonding coat 20, and wherein, bonding coat 20 is preferably as UV glue.
Concrete, this diffusion flaggy comprises: diffuser plate main body; This diffuser plate has the incidence surface and exiting surface that are oppositely arranged; Wherein, incidence surface has multiple incident area vertically opposite with light source, incident area has multiple first concave point and/or multiple first salient point; Exiting surface have multiple second concave point and/or multiple second salient point; The aperture area of the first concave point and the second concave point is π (D/2) 2; The base area of the first salient point and the second salient point is π (D/2) 2; π is circular constant, and D value is 5 ~ 300 μm.
It should be noted that, first, diffuser plate main body can adopt the light transmissive polymeric material such as polystyrene (PS), polycarbonate (PC), tygon (PE), polypropylene (PP), Polyvinylchloride (PVC), polyethylene terephthalate (PET), acryl (PMMA), acrylic acid (MMA) or synthetic material to form.
Wherein, diffusion particle (as resin or acrylic sphere) has been dispersibled in diffuser plate main body further, to improve the reflectivity to the light injecting diffuser plate body interior further.
Preferably, diffuser plate comprises: main body flaggy and thermoplastic resin; Thermoplastic resin is attached to upper surface and/or the lower surface of main body flaggy; The material of main body flaggy is PS; The material of thermoplastic resin is the one in PMMA, PO, PP, PE and MS; In main body flaggy and thermoplastic resin, also infiltration has optics master batch.Wherein, main body flaggy and thermoplastic resin form integrative-structure through extrusion molding.
Preferably, the outside surface of thermoplastic resin is also distributed with the optical grains of the young line of worm; The density of main body flaggy is 1.04 ~ 1.06g/cm3; The density of thermoplastic resin is 0.92 ~ 0.95g/cm3.More preferably, the density of main body flaggy is 1.05g/cm3, and the density of thermoplastic resin is 0.93/cm3.
Light source is through including the optics master batch of diffusant, and after dispersed, also after thermoplastic resin, twice dispersing can occur, therefore, diffuser plate of the present invention, transmittance is improved well.The young line of worm has the advantage that scratch resistant scratches, and foreign matter more anti-than frosted line is easy to clean.
Above-described embodiment is preferred version of the present invention, and the present invention also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent modification or replacement are all included in the scope set by the application's claim.
