Abstract

The utility model relates to a diffusion film and a prism film of a liquid crystal screen. The utility model has mainly technical proposal that a conventional diffusion film and a conventional prism film are made from general optical fiber array; the general optical fiber array is formed by that a plurality of short and general optical fibers are combined into flaky piece bodies of which directions are the same; the conventional diffusion film and the conventional prism film can be also made from micro-optical fiber array formed from micro-optical fibers. Accordingly, the direction of travel of light can be changed or controlled, which leads pictures displayed by the liquid crystal screen to be delicate and clear.

Description

Diffusion barrier in the liquid crystal screen and prism film
Technical field
The utility model relates to liquid crystal screen, especially refer to diffusion barrier and prism film in a kind of liquid crystal screen (LIQUID CRYSTAL DISPIAYLCD), can make by fiber array respectively, can change or control diffusion barrier and prism film in the liquid crystal screen of working direction of light.
Background technology
At present, commonly use the structure of liquid crystal screen A, as shown in Figure 1, be to constitute module backlight (LCM) E (being a kind of optics of metals element), with the whole liquid crystal screen A of liquid crystal screen battery (TFT Cell) F and liquid crystal screen (TFT) panel G formation by light guide plate B, diffusion barrier C, prism film (BEF) D.Wherein, prism film D can be a slice or two.The liquid crystal screen of this kind structure still can be suitable for practicality, but the picture displayed quality is still exquisite inadequately.
The utility model content
Fundamental purpose of the present utility model, be to provide diffusion barrier and prism film in a kind of liquid crystal screen, it can make the shown picture of liquid crystal screen exquisiter clear, it mainly is that diffusion barrier in the liquid crystal screen and prism film are made by general fiber array respectively, can change or control the working direction of light.
A purpose more of the present utility model is to provide diffusion barrier and prism film in a kind of liquid crystal screen, and it is that diffusion barrier in the module backlight and prism film are made by the low-light fibre array, makes quality of display pictures even more ideal.
For reaching above-mentioned purpose, diffusion barrier and prism film in a kind of liquid crystal screen of the present utility model is characterized in that: mainly be that diffusion barrier and the prism film that will commonly use made by general fiber array respectively; This general fiber array is made of the sheet lamellar body that the short general optical fiber of complex root is combined into the direction unanimity.Wherein,
Described as one of them fiber array constituted by a low-light fibre array.
Described low-light fibre array can be in the every general optical fiber and makes by complex root low-light fibre.
Because diffusion barrier and prism film in the liquid crystal screen that employing fiber array structure is made so can change or control the working direction of light, make the shown picture of liquid crystal screen exquisiter clear.
Description of drawings
Fig. 1, for commonly using the perspective exploded view of liquid crystal screen structure.
Fig. 2,3, be the enlarged diagram of the general fiber array structure of the utility model.
Fig. 4, the enlarged diagram that to be light transmit in general optical fiber inner total reflection.
Fig. 5, for being provided with the enlarged diagram of complex root low-light fibre in every general fiber array.
Embodiment
Referring to Fig. 1-4, diffusion barrier in a kind of liquid crystal screen and prism film are that diffusion barrier C and the prism film D that will commonly use made by general fiber array 1 respectively.This general fiber array 1 is made of the sheet lamellar body that the short general optical fiber (0ptical fiber) 2 of complex root is combined into the direction unanimity.Wherein, every general optical fiber 2 all is that total reflection (the internal total reflection) principle of utilizing light is transmitted light, and as shown in Figure 4, every general optical fiber 2 is divided equally internal layer 3 and outer 4, the material refractive index of internal layer 3 is about 1.8, and the refractive index of cladding material is about 1.4.Owing to adopt total reflection, thus incident angle greater than the light of critical angle, and the direction of transfer in every general optical fiber 2 is as shown in arrow 5, can be passed to the other end from an end of every general optical fiber 2.The diameter of every general optical fiber 2 is very thin, only has several microns, thus the light of injecting from light guide plate B 6, via the transmission of the general optical fiber 2 of complex root, can with the light that penetrates from its other end 7 minutes very thin, and make the picture on the liquid crystal screen G exquisiter clear.
Referring to Fig. 5, for making by complex root low-light fibre 8 in the every general optical fiber 2, thereby can be made into a kind of low-light fibre array, then its liquid crystal screen G goes up the picture displayed effect and more is better than general fiber array.

Claims (3)

1, diffusion barrier and the prism film in a kind of liquid crystal screen is characterized in that: mainly be that diffusion barrier and the prism film that will commonly use made by general fiber array respectively; This general fiber array is made of the sheet lamellar body that the short general optical fiber of complex root is combined into the direction unanimity.
2, diffusion barrier and the prism film in the liquid crystal screen according to claim 1 is characterized in that: described as one of them fiber array constituted by a low-light fibre array.
3, diffusion barrier and the prism film in the liquid crystal screen according to claim 2 is characterized in that: described low-light fibre array can be in the every general optical fiber and makes by complex root low-light fibre.
