Abstract
The invention discloses a prism film in a visual angle deflection structure. The prism film comprises a PET substrate, a UV resin layer and prism microstructures. One surface of the PET substrate is coated with the UV resin layer; and the UV resin layer is pressed by a roller to form the prism microstructures arranged along the longitudinal direction of the PET substrate, wherein adjacent prism edges of any two adjacent prism microstructures are arranged in the same line, and top angle prism edges of each prism microstructure deflect to the preset light outgoing direction. The prism film is simple in structure; and the two light outgoing surfaces of each prism microstructure are in asymmetrical design according to use requirements, so that the light outgoing angle of a displayer increases in the preset direction, the outgoing rays in the preset direction increase, the brightness is enhanced, and the liquid crystal displayer is allowed to have a visual angle deflection function.
Description
Technical field
The present invention relates to LCD backlight source technical field, be 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 present invention proposes a kind of visual angle deflection structure prism film, make liquid crystal display possess visual angle deflection, carry out the asymmetry design of prism 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, and brightness increases.
Summary of the invention
Technical matters solved by the invention 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.
Technical matters solved by the invention 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.
Structure of the present invention 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 invention, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the present invention 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 present invention adopts and process 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 present invention 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 invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and instructions just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Claimed scope of the present invention is defined by appending claims and equivalent thereof.
