Abstract
The utility model relates to an energy-saving anti-scratching bright enhancement film which comprises a triangular prism structure layer and a PET (polyethylene terephthalate) layer, the triangular prism structure layer is connectedly arranged on the upper portion of the PET layer, the triangular prism structure comprises high triangular prisms and low triangular prisms, five low triangular prisms are arranged between two adjacent high triangular prisms, and a shadowless glue layer with a graft elastomer and memory function is covered on the surfaces of the low triangular prisms and the high triangular prisms. The energy-saving anti-scratching bright enhancement film can improve the scratch resistance of the parallel triangular prism structure layer of the surface of a bright enhancement film, while the surface of the triangular prism structure layer is scratched by external force the surface can automatically recover in 30 seconds, the scratch will disappear without a protecting film, pollution is avoided, manpower resource is reduced, energy consumption is reduced, and the assembly efficiency of a backlight module is improved.
Description
Technical field
The utility model relates to the bright enhancement film technical field, particularly a kind of energy-conservation anti-type bright enhancement film of scraping.
Background technology
At present, bright enhancement film (BEF) is widely used in module backlight to be used for converging the light that light source is sent.The principle of bright enhancement film is through reflection the light outside the directive observer visual angle to be adjusted within the observer visual angle, has so just improved the utilization factor of luminous energy that light source sends.Traditional bright enhancement film has front protecting film and back protection film, when module backlight is assembled, need throw off diaphragm simultaneously; Because the bright enhancement film product all can have some static when production, itemize, cross cutting, remove in the process of diaphragm, makes some flying dust or granule be adsorbed onto the diaphragm front or the back side easily; Make diaphragm receive pollution, if artificial assembling process, the careless grazing of finger or instrument all can damage prismatic surface structures; Produce tangible scratch, reduced effective rate of utilization.
The utility model content
The purpose of the utility model is to overcome the defective that traditional bright enhancement film product itself exists, and a kind of unprotect film is provided, and has good brightening effect to scrape effect with anti-, can improve the energy-conservation anti-type bright enhancement film of scraping of the packaging efficiency of module backlight.
The technical scheme that realizes the utility model purpose is: a kind of energy-conservation resisting scraped the type bright enhancement film, has triangular prism structure layer and pet layer; The setting of said triangular prism structure layer is connected the pet layer top; Said triangular prism structure layer has high triangular prism and low triangular prism; Be provided with five low triangular prisms between adjacent two high triangular prisms; The surface of said high triangular prism and low triangular prism all be covered with a kind of have anti-scrape function contain the elastomeric no shadow glue-line of grafting.
Technique scheme also has back coating; Said back coating setting is connected the below of pet layer.
The thickness of the said pet layer of technique scheme is 188 μ m or 250 μ m.
The bottom side length of the said high triangular prism of technique scheme is 54 μ m, and drift angle is 90 °.
The bottom side length of the said low triangular prism of technique scheme is 50 μ m, and drift angle is 90 °.
The mist degree of the said back coating of technique scheme is (12 ± 3) %.
The utlity model has positive effect:
(1) the utility model adopt the surface of high triangular prism and low triangular prism all be covered with a kind of have anti-scrape function contain the elastomeric no shadow glue-line of grafting, not only can improve the resistance to scraping of the parallel triangular prism structure layer on bright enhancement film surface, the triangular prism structure laminar surface is when receiving external force and produce scratch; Can in 30s, restore to the original state voluntarily, scratch disappears, and need not protective film; Avoid polluting; Reduce human resources, reduced energy consumption, improved the packaging efficiency of module backlight.
(2) the utility model adopts between adjacent two high triangular prisms and is provided with five low triangular prisms; Height combines; High triangular prism can be supported another sheet bright enhancement film or diffusion sheet, avoid bright enhancement film to stack or module backlight when assembling produces the dirty phenomenon of static; Simultaneously, utilize the parallel triangular prism structure on bright enhancement film surface,, thereby make brightness increase by 50%～70% most light refraction optically focused.
(3) the utility model also has back coating; The back coating setting is connected the below of pet layer; Back coating can make bright enhancement film keep original brightening effect, also has the effect of diffusion barrier, and is reasonable in design, practical.
Description of drawings
For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing
Fig. 1 is the structural representation of the utility model;
1. triangular prism structure layers among the figure, 11. high triangular prisms, 12. low triangular prisms, the 2.PET layer, 3. back coating does not 4. have the shadow glue-line.
Embodiment
See Fig. 1, the utlity model has triangular prism structure layer 1 and pet layer 2; Triangular prism structure layer 1 is provided with and is connected pet layer 2 tops; The thickness of pet layer 2 is 188 μ m or 250 μ m; Triangular prism structure layer 1 has high triangular prism 11 and low triangular prism 12; Be provided with five low triangular prisms 12 between adjacent two high triangular prisms 11; The surface of high triangular prism 11 and low triangular prism 12 all be covered with a kind of have a memory function contain the elastomeric no shadow glue-line 4 of grafting; The bottom side length of high triangular prism 11 is 54 μ m, and drift angle is 90 °; The bottom side length of low triangular prism 12 is 50 μ m, and drift angle is 90 °.
Also has back coating 3; Back coating 3 is provided with the below that is connected pet layer 2; The mist degree of back coating 3 is (12 ± 3) %.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
