Abstract
The utility model provides a brightness enhancement film, and belongs to the field of liquid crystal display. The brightness enhancement film comprises a substrate and a structural layer. The substrate is a PET backboard, the structural layer comprises at least five triple prisms, the triple prisms are arranged on one side of the PET backboard, and the distance between the arris, of each triple prism, being far from the PET backboard, and the PET backboard is constant and is 12[mu]m-14[mu]m. By employing the above structure, negative optical effects such as Newton rings and moire interference and the like can be effectively reduced, optical performance effects of the brightness enhancement film are relatively good, electrostatic pollution phenomena generated when the brightness enhancement film and a diffusion barrier are stacked up are reduced, at the same time, the triple prisms are equal in height, and therefore damages generated during touch, product stack and assembly processes are reduced.
Description
Technical field
The utility model relates to field of liquid crystal display, in particular to brightness enhancement film.
Background technology
At present, brightness enhancement film is widely used in illuminating module increases display brightness and the energy of saving display battery apparatus to be used for converging normal application brightness enhancement film (BEF) in the display devices such as the light that light source is sent, especially liquid crystal display.Traditional brightness enhancement film optical effect expression effect is poor.
Utility model content
The utility model provides a kind of brightness enhancement film, is intended to solve the poor problem of traditional brightness enhancement film optical effect expression effect.
The utility model is achieved in that
A kind of brightness enhancement film, comprises substrate and structural sheet, and described substrate is PET backboard, described structural sheet comprises at least 5 prisms, described prism is arranged on a side of described PET backboard, and each described prism equates to the distance of described PET backboard away from the rib of described PET backboard, is 12-14 μ m.
This structure can effectively reduce Newton ring and the generation of the negative optical effects such as line interference that change, optical appearance effect is better, the static contamination phenomenon producing while stacking between minimizing brightness enhancement film and diffusion barrier, meanwhile, the contour damage that can reduce in the processes such as touch, product stack, assembling of prism.
Further, the xsect of each described prism is isosceles triangle, the base of described isosceles triangle and the laminating of described PET backboard, and the drift angle angle of described isosceles triangle is 85 °-95 °.Drift angle angle is 85 °-95 ° scopes that can control easily light.
Further, the drift angle of described isosceles triangle is circular-arc, and the arc radius of circular-arc drift angle is less than or equal to 2 μ m.Circular-arc drift angle reduces the scuffing in product stack, assembling process.
Further, the surface roughness Ra of described prism is less than or equal to 20 μ m.Surface roughness Ra compared with I so that prism is more smooth.
Further, described prism uniformly-spaced arranges.Uniformly-spaced arrange and make distribution of light more even.
The beneficial effects of the utility model are: this structure can effectively reduce Newton ring and the generation of the negative optical effects such as line interference that change, the static contamination phenomenon producing while stacking between minimizing brightness enhancement film and diffusion barrier, meanwhile, the contour damage that can reduce in the processes such as touch, product stack, assembling of prism.
Accompanying drawing explanation
