Description
Technical field
The utility model relates to LCD backlight source technical field, is specially a kind of visual angle deflection structure prism film.
Background technology
Current backlight key component comprises light source, light guide plate, all kinds of blooming, and all kinds of blooming mainly comprises reflectance coating, diffusion barrier and prism film.Wherein prism film is that original diverging light is with great visual angle gathered outgoing in less angular range, thus increases brightness, and prism film is the microstructure that acryl resin is made in PET base material.As shown in Figure 1, general microstructure is isosceles triangle, and prism 2 is highly 20 ~ 50um, and angularity is 90 °.After general LCD has assembled, light picture, exiting surface concentrates on display frontal and direction, 40 °, left and right.But for the display of some specific uses, such as Vehicular display device, visual angle deflection be possessed, need the microstructure by changing prism film, reaching the effect of visual angle deflection.Therefore the utility model proposes a kind of visual angle deflection structure prism film, liquid crystal display is made to possess visual angle deflection, the asymmetry design of prism exiting surface both sides is carried out according to request for utilization, display rising angle is made to become large at preset direction, the emergent ray of this preset direction is increased, and brightness increases.
Utility model content
The technical matters that the utility model solves is to provide a kind of visual angle deflection structure prism film, and structure is simple, and make display rising angle become large at preset direction, the emergent ray of this preset direction is increased, and brightness increases.
The technical matters that the utility model solves realizes by the following technical solutions:
A kind of visual angle deflection structure prism film, comprise PET base material, UV resin bed, prism microstructure, at described PET base material coated on one side UV resin bed, UV resin bed is made into the prism microstructure of longitudinally arranging along PET base material through running roller impression, the adjacent seamed edge of arbitrary neighborhood two prism microstructure is arranged on same straight line, and the drift angle seamed edge of each prism microstructure is all partial to default light direction.
Preferably, prism microstructure exiting surface designs for asymmetry.
Preferably, the corner angle of prism microstructure is 0 ~ 180 °.
Preferably, the height of prism microstructure is 0 ~ 50 μm.
The utility model structure is simple, carry out the asymmetry design of prism microstructure exiting surface both sides according to request for utilization, make display rising angle become large at preset direction, the emergent ray of this preset direction is increased, brightness increases, thus makes liquid crystal display possess the function of visual angle deflection.

Embodiment
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in figs. 2 to 4, a kind of visual angle deflection structure prism film, comprise PET base material 1, UV resin bed, prism microstructure 2, at described PET base material 1 coated on one side UV resin bed, UV resin bed is made into the prism microstructure 3 of longitudinally arranging along PET base material through running roller impression, the adjacent seamed edge of arbitrary neighborhood two prism microstructure 3 is arranged on same straight line, and the drift angle seamed edge of each prism microstructure 3 is all partial to default light direction.Wherein, prism microstructure 3 exiting surface designs for asymmetry, and the corner angle of prism microstructure 3 is 0 ~ 180 °, and the height of prism microstructure 3 is 0 ~ 50 μm.
With reference to Fig. 2, Fig. 3, Fig. 4, the corner angle of the prism structure in Fig. 2 is less than the corner angle of Fig. 3 prism structure, and in Fig. 4, the default deflection light direction of prism film is contrary with Fig. 3.
The utility model adopts processes asymmetric prism microstructure on impression running roller, and at the surperficial coating UV resin bed of PET base material 1, through running roller impression, after UV resin bed photocuring, pet sheet face microstructure makes shaping, and overlay film is protected.The utility model makes displaying appliance for the function of visual angle directive property, exiting surface angle (left and right directions) asymmetry of liquid crystal display, display rising angle becomes large at preset direction, and the emergent ray of this angle direction is increased, brightness increases, and reaches the function of visual angle deflection.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
