Abstract
The utility model relates to a kind of optical polyester film, comprises the reflection horizon and the diffusion layer that is positioned at upper and lower both sides, reflection horizon at middle part; The thickness of described diffusion layer is 1-30 micron; Described reflection horizon is distributed with reflection horizon particle; Described diffusion layer is distributed with diffusivity particle, and the particle diameter of described diffusivity particle is 0.2-0.4 micron; Solve light consume serious, the problem that light saturation degree is low; Reflectivity is higher, light diffusing can be better.
Description
Technical field
The utility model belongs to technical field of liquid crystal display equipment, is specifically related to a kind of optical polyester film.
Background technology
Backlight module (Backlight Module) is Thin Film Transistor-LCD (Thin Film Transi stor Liquid Crystal Display, be called for short TFT-LCD) light emitting source, use optical thin film, light guide plate, cold cathode fluorescent lamp group, or the composition such as LED striation, backboard and frame of plastic.Because of liquid crystal itself not luminous, for being known, user sees the upper shown content of LCD, must add at the LCD back side backlight module that can project light source, light is seen through after LCD, communicate information in user's eye, therefore backlight module is one of LCD panel (key part and component).Backlight module is not the light source of liquid crystal display, also affects briliancy, uniformity coefficient, picture taste and the visual angle of LCD.
The main member of backlight module system comprises: light source, light guide plate, all kinds of blooming piece.Wherein light source mainly contains EL, CCFL and LED three types, can be divided into two kinds of side-light type and straight-down negatives according to distribution of light sources position difference.Along with LCD module constantly to brighter, gentlier, thinner future development, side-light type CCFL backlight becomes the main flow of current backlight development.Blooming piece mainly comprises reflectance coating, diffusion barrier and brightness enhancement film.The Main Function of reflectance coating is to improve the reflectivity of optical surface, will spill light high-level efficiency and lossless the reflection of light guide plate bottom, thereby reduces light consume, reduces power consumption, improves the light saturation degree of liquid crystal display.
In addition, in LCD backlight module, pointolite or line source need to be atomized into uniform area source.Therefore, reflectance coating not only needs very high reflectivity, also will as much as possible incident ray be reflected away with irreflexive form, to improve the briliancy of panel of LCD and to control the even of brightness.This will ask reflectance coating surface to have certain light diffusion.
Utility model content
The purpose of this utility model is to provide the optical polyester film that a kind of reflectivity is high, light diffusing can be good.
The technical scheme that realizes the utility model object is: a kind of optical polyester film, the reflection horizon in the middle part of comprising and the diffusion layer that is positioned at upper and lower both sides, reflection horizon; The thickness of described diffusion layer is 1-30 micron.
Preferred described reflection horizon is distributed with reflection horizon particle.
Preferred described diffusion layer is distributed with diffusivity particle, and the particle diameter of described diffusivity particle is 0.2-0.4 micron.
The utlity model has positive effect: reflection horizon is to melt extrude by two-way stretch main extruder, diffusion layer is to melt extrude by the auxiliary extruder of two-way stretch, obtain having concurrently that reflectivity is higher, light diffusing can better optical polyester film, lower diffusion sheet can be cancelled from backlight module, make LCD module to brighter, gentlier, thinner future development, and reduce starting material and production cost.
Brief description of the drawings
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is a kind of structural representation of optical polyester film;
The 1st, reflection horizon, the 2nd, diffusion layer, the 3rd, reflection horizon particle, the 4th, diffusivity particle
Embodiment
See Fig. 1, the utlity model has a kind of optical polyester film, comprise the reflection horizon 1 and the diffusion layer 2 that is positioned at both sides Shang Xia 1, reflection horizon at middle part; The thickness of described diffusion layer 2 is 1-30 microns.
Further described reflection horizon 1 is distributed with reflection horizon particle 3, and described reflection horizon particle 3 comprises two kinds of organic filler and inorganic particulates: wherein organic filler is selected from one or more in isobornyl acrylate, isobornyl methacrylate, methyl acrylate, methyl methacrylate, styrene, glycidyl acrylate, glycidyl methacrylate, vinyl cyanide; Wherein inorganic particulate is selected from one or more in calcium carbonate, titanium dioxide, talcum powder, barium sulphate.
Further described diffusion layer 2 is distributed with diffusivity particle 4, and the particle diameter of described diffusivity particle 4 is 0.2-0.4 microns; Described diffusivity particle 4 comprises organic diffusant and inorganic diffusant, and described organic diffusant comprises acrylic type, styrene type, acryl resin type; Described inorganic diffusant comprises nano barium sulfate, titanium dioxide, silicon dioxide, calcium carbonate.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
