Abstract
The utility model discloses a microprism-structure liquid crystal display brightness enhancement film made by the hot-pressing technology. The brightness enhancement film is made of one-layer film material, the upper surface of the hot-pressing liquid crystal display brightness enhancement film is a smooth interface, and the lower surface of the hot-pressing liquid crystal display brightness enhancement film is an interface formed by a microprism structure which can perform multiple reflections and refractions of the light so as to collect the light. The brightness enhancement film is simple in process flow, causes no pollution to the environment and widens the production scope of the existing materials.
Description
Technical field
The utility model belongs to the brightness enhancement film material type of liquid crystal display backlight assembly.Specifically, this material is a kind of film of the single layer structure of making by hot press forming technology, and the sight line that it has, and diverging light with wide-angle is brought in the specified scope, part light is constantly impacted the people by refraction reflection repeatedly strengthens the function that LCD is faced brightness effect to reach.The utility model is a kind of film that the enhancing LCD is faced bright function that has.
Background technology
Liquid crystal display brightness enhancement film on the present stage market all is to adopt the UV ultraviolet curing process to make.Company adopts hot press forming technology to make the liquid crystal display brightness enhancement film, and technological process is few, and operation is easy to control, and its technology realization flow meets the green non-pollution standard.
Summary of the invention
The utility model is by the liquid crystal display brightness enhancement film mould with micro-prism structure form film heating and pressurizing moulding process to be formed, and its surface chart is a zigzag, and vertical view is the V-type ditch of a lot of conduct.This hot-forming liquid crystal display brightness enhancement film generally is transparent plastics, and its upper surface is level and smooth interface, and lower surface is to have repeatedly reflection, refracted ray with the formed interface of the micro-prism structure that converges light.The utility model is made by one or more the material among polycarbonate PC, polymethyl methacrylate PMMA, polyvinylchloride, poly terephthalic acid PET, polyamide PA, the polystyrene PS, be a kind of film of single layer structure, it has converging and diverging light and faces the function of light intensity to strengthen LCD.This use new production process flow process please refer to Fig. 3, Fig. 4.
Description of drawings
Fig. 1,2 is respectively the utility model section structure synoptic diagram and vertical view.
Fig. 3, Fig. 4 are that technological process of the present utility model realizes synoptic diagram.
Embodiment
Below in conjunction with embodiment the utility model is further described, but embodiment of the present utility model is not limited thereto.
Embodiment
According to shown in Figure 1, the utility model is to be made of the micro-prism structure film that one deck has good optically focused and a reflecting properties.The utility model upper surface is a smooth flat, below for having the microprism interface of reflection ray.The utility model adopts hot press forming technology to make, and at first faces light according to difference and strengthens the microprism mold that angle requires to design and produce out relevant parameter, utilizes this mould can finish through heating and pressurizing, releasing process the moulding smooth film again.
The utility model requires to cut into overlapping the installing and using of other retes of corresponding shape and liquid crystal display backlight assembly according to the difformity of display.
As mentioned above, just can well realize the utility model.
