Abstract

The invention discloses a composite bright enhancement film, comprising a transparent film layer, a light collecting layer and an atomizing layer, wherein the light collecting layer, the atomizing layer and the transparent film layer are integrally arranged; the light collecting layer and the atomizing layer are integrally arranged. The composite bright enhancement film adopts a single-layer structure design, and uses a saw-tooth shaped refraction surface of the light collecting layer to enhance the bright. The light is diffracted by beads with different convex hemisphere grain sizes arranged on the atomizing layer, thereby achieving atomizing and diffusing effects. Compared with the traditional backlight module, the composite bright enhancement film can reduce more than one diffusion film, and can reduce the manufacturing steps of double coating the multi-layer diffusion films in the traditional manufacturing process, thereby greatly reducing the cost and improving the operating quality.

Description

Compound bright enhancement film
Technical field
The present invention relates to technical field of liquid crystal display, relate in particular to a kind of compound bright enhancement film.
Background technology
Traditional LCD (TFT-LCD) mainly is made up of liquid crystal panel and module backlight.The structure of traditional module backlight is as shown in Figure 1; This module backlight has LGP 11; The bottom surface of LGP 11 is provided with reflecting plate 110, and the incidence surface of LGP 11 is provided with light source 10, and the exiting surface of LGP 11 is provided with first diffusion barrier 12; Two layers of brightness enhancement film 13 are set on first diffusion barrier 12, add second diffusion barrier 14 of one deck tool protective effect at last.
The module backlight of this structure need use more blooming piece, and cost is higher, and the light source utilization factor is not good yet.
Summary of the invention
The purpose of this invention is to provide a kind of compound bright enhancement film, the cost that is intended to solve traditional module backlight is higher, and the not good problem of light source utilization factor.
Technical scheme of the present invention is following:
A kind of compound bright enhancement film comprises transparent film layer, light collecting layer, atomizing layer, and said light collecting layer and atomizing layer and transparent film layer are wholely set, and light collecting layer and atomizing layer are oppositely arranged.
Described compound bright enhancement film, wherein, said light collecting layer is the V-cut concentration structure.
Described compound bright enhancement film, wherein, said light collecting layer comprises a plurality of evenly distributed jagged plane of refraction and projections, said projection disperses to be arranged between the jagged plane of refraction.
Described compound bright enhancement film, wherein, the spacing of adjacent jagged plane of refraction is 28 to 50 microns, the spacing of adjacent projection is 140 to 200 microns.
Described compound bright enhancement film, wherein, the height of jagged plane of refraction is 15 microns, the height of projection is 19 microns.
Described compound bright enhancement film, wherein, said atomizing layer comprises the pearl body of a plurality of evenly distributed protruding dome-type particle diameters.
Described compound bright enhancement film, wherein, the diameter of the pearl body of said protruding dome-type particle diameter is 3 to 10 microns, its roughness Ra value is 0.24 to 0.3 micron.
Described compound bright enhancement film, wherein, the thickness of said transparent film layer is 50 microns.
The present invention adopts the structural design of simple layer, utilizes the zigzag plane of refraction of light collecting layer can reach the effect of adding lustre to.Utilize the pearl body of the protruding dome-type particle diameter not of uniform size of atomizing layer to make light produce x-ray diffraction, reach the atomizing diffusion effect.Compare with traditional module backlight, the present invention can reduce the diffusion barrier more than, in the time of more reducing tradition and make, needs the making step with multilayer diffusion barrier double spread, thereby can significantly reduce cost and can promote the operation quality.

Embodiment
The invention provides a kind of compound bright enhancement film and module backlight, clearer, clear and definite in order to make the object of the invention, technical scheme and advantage, below will combine accompanying drawing and embodiment, to further explain of the present invention.
See also Fig. 2 to Fig. 4, compound bright enhancement film of the present invention comprises transparent film layer 2, light collecting layer 21, atomizing layer 22, and light collecting layer 21 is wholely set with atomizing layer 22 and transparent film layer 2, and light collecting layer 21 is oppositely arranged with atomizing layer 22.
The material of said transparent film layer 2 is poly terephthalic acid (PET).The thickness of said transparent film layer 2 is about 50 microns.
Said light collecting layer 21 is the V-cut concentration structure; Comprise a plurality of evenly distributed jagged planes of refraction 210 and projection 212; Projection 212 disperses to be arranged between the jagged plane of refraction 210, and the spacing of adjacent jagged plane of refraction 210 is 28 to 50 microns, and the spacing of adjacent projection 212 is 140 to 200 microns; The height of jagged plane of refraction 210 is about 15 microns, and the height of projection 212 is 19 microns.The refraction optically focused that cooperates jagged plane of refraction 210 can produce the more translucent effect of homogeneous and bright, reaches the effect of focused ray, increase brightness.And, when it is combined with other retes, utilize projection 212 to withstand last layer in advance, thereby can prevent jagged plane of refraction 210 direct contacts and produce scratch with a last rete by the projection 212 that suitable spacing is provided with.
Said atomizing layer 22 comprises the pearl body 220 of a plurality of evenly distributed protruding dome-type particle diameters, and the diameter of the pearl body 220 of said protruding dome-type particle diameter is 3 to 10 microns, and its roughness Ra value is 0.24 to 0.3 micron.The pearl body 220 of said protruding dome-type particle diameter is that employing has the recessed dome-type particle diameter body of optical microstructures and the optical grade acrylic ester of liquid high index of refraction combines to duplicate formed.The effect of the pearl body 220 of this protruding dome-type particle diameter is to make light produce x-ray diffraction, has the atomizing diffusion effect.
When using compound bright enhancement film of the present invention, only need its exiting surface that is arranged on LGP is got final product, atomizing layer 22 is contacted with the exiting surface of LGP.The upper strata diffusion barrier and the brightness enhancement film of the alternative traditional module backlight of compound bright enhancement film of the present invention.
The present invention adopts the structural design of simple layer, utilizes the zigzag plane of refraction 210 of light collecting layer 21 can reach the effect of adding lustre to.Utilize the pearl body 220 of the protruding dome-type particle diameter not of uniform size of atomizing layer 22 to make light produce x-ray diffraction, reach the atomizing diffusion effect.
Compare with traditional module backlight, the present invention can reduce the diffusion barrier more than, in the time of more reducing tradition and make, needs the making step with multilayer diffusion barrier double spread, thereby can significantly reduce cost and can promote the operation quality.
Should be understood that; Above-mentioned description to preferred embodiment is comparatively detailed, can not therefore think the restriction to scope of patent protection of the present invention, and those of ordinary skill in the art is under enlightenment of the present invention; Do not breaking away under the scope situation that claim of the present invention protects; Can also make various deformation such as replacement, simple combination, these all fall within protection scope of the present invention, and the scope of asking for protection of the present invention should be as the criterion with accompanying claims.
