Abstract
The utility model discloses a composite type brightness enhancement film. The composite type brightness enhancement membrane has a PET layer, a microstructure prism layer and a diffusion layer, wherein the microstructure prism layer is arranged to be connected with the upper part of the PET layer, the diffusion layer is arranged below the microstructure prism layer, the microstructure prism layer has high semicircular prisms and low triangular prisms, and at least three low triangular prisms are arranged between two adjacent high semicircular prisms. According to the utility model, since the prisms have an anti-scratch function and complete self-healing in 10 s after an external force is applied, and a yield rate of a product in each assembling link is improved; the high semicircular prisms can prop up another brightness enhancement film, so the phenomenon of electrostatic pollution is prevented when the brightness enhancement films are stacked or backlight modules are assembled; and most of light rays are condensed through reflection and refraction by using the microstructure prism layer, so brightness is increased by 50 to 70%.
Description
Technical field
The utility model relates to a kind of multi-functional bright enhancement film technical field, particularly a kind of have improve antistatic dirt, the compound bright enhancement film of anti scuffing self-healing.
Background technology
At present, bright enhancement film (BEF) is widely used in illuminating module to be used for converging the light that light source is taken place.The principle of bright enhancement film is by reflection, refraction 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.The prism structure unit of traditional bright enhancement film is rule and contour structure, though also have in the actual use of brightening effect, bright enhancement film in use hold by scratch and and diffusion barrier between be easy to generate problem such as static dirt phenomenon when stacking.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, adopt the multi-functional bright enhancement film of height prism arrangement design, easily produce the dirty phenomenon of scratch and static when having reduced module backlight assembling, and can guarantee a kind of compound bright enhancement film of good brightening effect.
The purpose of this utility model realizes as follows: a kind of compound bright enhancement film, have pet layer, microstructure layers of prisms and diffusion layer, and the setting of described microstructure layers of prisms is connected the top of pet layer, and its below is provided with described diffusion layer; Described microstructure layers of prisms has high semi-circular prism and low triangular prism; Be provided with at least three low triangular prisms between adjacent two high semicircle prisms.
Above-mentioned a kind of compound bright enhancement film, its described microstructure layers of prisms height prism height difference H is 2 to 4 μ m.
Above-mentioned a kind of compound bright enhancement film, the low triangular prism drift angle in its described microstructure layers of prisms is 90 °
Above-mentioned a kind of compound bright enhancement film, the high semi-circular prism diameter range in its described microstructure layers of prisms are that D is 54 to 58 μ m.
Above-mentioned a kind of compound bright enhancement film, its described diffusion layer is made up of male and fomale(M﹠F) not of uniform size.
Above-mentioned a kind of compound bright enhancement film, its described pet layer, microstructure layers of prisms and diffusion layer top and bottom all have the unprotect rete, and the microstructure layers of prisms also has the QQ glue-line for self-healing function.
Advantage of the present utility model: 1, Mobyneb bright enhancement film of the present utility model, have and can improve antistatic dirt, anti scuffing self-healing function microstructure layers of prisms, pet layer and diffusion layer, described diffusion layer has the function of diffusion and anti-absorption.Wherein said microstructure layers of prisms adopts between adjacent two high semi-circular prisms and is provided with at least three low triangular prisms; Because this prism has anti-scratch function, after being subjected to external force, finish self-healing function in the 10S, promote product at the yield of each assembling link; High semicircle prism can support another sheet bright enhancement film, avoids bright enhancement film to stack or backlight film group assembling time produces the dirty phenomenon of static; Utilize microstructure layers of prisms (semi-circular prism, triangular prism) with most light reflected refraction optically focused simultaneously, thereby make brightness increase 50%-70%.
2, above-mentioned three layers top and bottom all have or not protective film, and the microstructure layers of prisms also has the QQ glue-line of anti-scratch self-healing function.
