Abstract
The utility model discloses a light enhancement piece, which at least comprises a base material, a light enhancement layer and an inorganic layer, wherein the inorganic layer is arranged between the base material and the light enhancement layer; the base material is stably jointed with the light enhancement layer by the inorganic layer without causing separation; and the refractive index of the light enhancement piece is enabled to be larger than 1.6.
Description
Technical field
The relevant a kind of brightening piece structure of the utility model is meant a kind of brightening piece structure that improves refractive index especially.
Background technology
In recent years, that LCD (be called for short " LCD ") is being held under the arm is light, thin, short, little, heat and power consumption is low and the advantage of radiationless injury almost, progressively replaces conventional cathode ray tube (CRT) display.
Generally speaking; The primary structure of LCD comprises panel and module two large divisions backlight; Faceplate part comprises for example tin indium oxide (ITO) electro-conductive glass, liquid crystal, alignment film, colored filter, polaroid, driving IC etc., and module part backlight then comprises for example fluorescent tube, LGP and various bloomings etc.The whole optical appearance of LCD receives the reciprocal effect of all elements of module part backlight, and wherein, blooming has more been played the part of important role on screen intensity, uniformity coefficient, contrast and visual angle.
For can being appeared, LCD better views and admires angle and color, the existing many trials of industry at present, for example; Known can be by increasing the brightness that the fluorescent tube number improves the LCD panel; Yet this not only causes too much heat to be accumulated in LCD easily, and has influence on the life-span and the quality of other element; Can cause power consumption excessive simultaneously, must be dependent on the requirement that battery uses with off-line and can't satisfy many info class articles for use.
At present; In module backlight, utilize blooming miscellaneous; Provide a kind of and can improve the LCD panel luminance, become most economical and easy solution so that light source is done the performance of full blast, but need do not changed any element design or consume the way of additional energy source.
Brightness enhancement film is called for short BEF (Brightness Enhancement Film) usually or refers to condensing film; It can be by for example at thickness only on the polyester optical thin film of 125 μ m, utilizes high-energy ultraviolet ray (UV) that special acryl resin is hardened into the microscopic prisms structure and make.The main function of brightness enhancement film will be issued to ray-collecting at random from all directions by LGP (light guide) by refraction and inner full-reflection, and be concentrated to positive visual angle (on-axis) direction of degree approximately ± 35, to improve the brightness of LCD; Yet the refractive index of this individual layer acryl resin is still not high.
The utility model content
The technical matters that the utility model solved is promptly providing a kind of brightening piece structure that improves refractive index.
The technical scheme of the utility model is: a kind of brightening piece structure includes at least: a base material, this base material are provided with first, second relative surface; One lustre adding layer is located at the first surface of this base material, and this lustre adding layer is provided with plural prism structure; And an inorganic layer, be located between this base material and this lustre adding layer.
Wherein, this inorganic layer is the zirconia material.
This inorganic layer is the titania material.
The second surface of this base material is provided with a diffusion layer.
This diffusion layer is provided with plural microstructure.
The spacing of each prism structure is 50 μ m in this lustre adding layer.
The spacing of each prism structure is 25 μ m in this lustre adding layer.
This base material is the PET material.
The thickness of this inorganic layer is 0.1 ~ 15 μ m
The beneficial effect of the utility model is: the brightening piece of the utility model includes at least: a base material, a lustre adding layer and an inorganic layer; This inorganic layer is located between this base material and this lustre adding layer; By this inorganic layer can make this base material with this lustre adding layer firm engagement unlikely the separation, and make the refractive index of this brightening piece can be greater than 1.6.

The figure number explanation:
Lustre adding layer 12
Embodiment
Brightening piece structural perspective like Fig. 1 the utility model; And shown in the brightening piece structural representation of Fig. 2 the utility model; The brightening piece 10 of the utility model includes at least: a base material 11 (can be the PET material), a lustre adding layer 12 and an inorganic layer 13; This base material 11 is provided with first, second relative surface 111,112, and this lustre adding layer 12 is located at the first surface 111 of this base material, and this lustre adding layer 12 is provided with plural prism structure 121; The spacing of each prism structure 121 can be 50 μ m (perhaps can be 25 μ m); 13 of this inorganic layers are located at 12 of this base material 11 and this lustre adding layers, and this inorganic layer 13 can be zirconia or titania material, and the thickness of this inorganic layer 13 can be 0.1 ~ 15 μ m.
Wherein, this inorganic layer 13 can make this base material 11 with these lustre adding layer 12 firm engagement unlikely the separation, and after can making light penetrate via this inorganic layer 13 and this lustre adding layer 12, its refractive index can be greater than 1.6.
Moreover the second surface 112 of this base material is provided with a diffusion layer 14, and is as shown in Figure 3, and this diffusion layer 14 is provided with plural microstructure 141 (can be the site), to increase the diffusion effect of this brightening piece 10.
