Description

Module backlight with roll-in atomizing intermediate diffusion layer
Technical field
The utility model belongs to the light diffusion component, particularly a kind of module backlight with roll-in atomizing intermediate diffusion layer.
Background technology
Module backlight is widely used in liquid crystal (LCD) display, the scanner, as the usefulness of light diffusion, makes LCD and scanner can correctly bring into play its optics Presentation Function and scan function.Yet, in the diffuse layer structure of known module backlight, expand and penetrate effect owing to need to form light on its surface, and on its surface with wire mark coating chemical substance or spraying sand dual mode to form particle.Wherein, wire mark coating chemical substance mode is with titania (TiO 2) or silicon (SiO 2) two kinds of chemical substances by screen painting in its surface.The shortcoming of this mode is process complexity, cost height, high pollution, and chemical substance is difficult for being attached on the transparent plastic material, thereby the problem that very easily is subjected to scratch or peels off in processing procedure causes its product fraction defective to increase severely.Another problem of this kind half tone coating method then is chemical substance coating thickness and the easy skewness of particle thereof again, causes module overall light transmission inequality backlight or the not good problem of diffusion.
Another kind of to use the mode of spraying sand be by some, spraying diffusion layer surface at module backlight as mist sand shape beaded glass, penetrates effect to produce light expansion by each beaded glass particle.But its shortcoming is easily to produce to pollute in the sandblast process, and glass particle also is difficult for evenly spraying in module backlight surface, similarly, can cause the light diffusion uneven and make the clear problem of its effect.
Summary of the invention
The purpose of this utility model provides a kind of light diffusion uniformity, best in quality, one-piece construction processing is easy, cost is low, the free from environmental pollution module backlight with roll-in atomizing intermediate diffusion layer.
The utility model comprises transmission basal layer, is incorporated into the intermediate diffusion layer and the transparent protective film of transmission basal layer top; Transmission basal layer is the basic unit with transmission translucent effect; The intermediate diffusion layer surface that is incorporated into the transmission basal layer top is formed with roller line and the recessed joint of some series for light transmission diffusion in running roller roll-in mode; The transparent protective film of using protection intermediate diffusion layer surface is incorporated into the intermediate diffusion layer end face.
Wherein:
Transmission basal layer is to constitute with white PET plate.
Transmission basal layer is used the required chromatograph white of modulation concentration and is controlled its optical concentration.
The transmission basal layer bottom is combined with for it and sticks in the substratum transparent of the body surface of using.
The substratum transparent surface combination has release liners.
Intermediate diffusion layer is for to be made of transparent PC sheet.
The recessed joint bottom of intermediate diffusion layer is provided with a curved portions that supplies light source transmission radian not limit at least.
The recessed joint of intermediate diffusion layer is circular shape.
But the intermediate diffusion layer single or double is formed with the series of rollers line and the recessed joint of some any forms.
Intermediate diffusion layer can be regulated the roller line of its surface formation and the density of recessed joint according to required fogging degree.
Because the utility model comprises transmission basal layer, is incorporated into the intermediate diffusion layer and the transparent protective film of transmission basal layer top; Transmission basal layer is the basic unit with transmission translucent effect; The intermediate diffusion layer surface that is incorporated into the transmission basal layer top is formed with roller line and the recessed joint of some series for light transmission diffusion in running roller roll-in mode; The transparent protective film of using protection intermediate diffusion layer surface is incorporated into the intermediate diffusion layer end face.Make the utility model integral body have uniform transmission and diffusion effect by roller line and recessed joint, strengthen the optics diffusion effect, the surface does not have peels off or scratch damages, and significantly improves product quality, to reduce the fraction defective of product, process easy, cost is low and pollution-free.The processing of not only light diffusion uniformity, best in quality, and one-piece construction is easy, cost is low, free from environmental pollution, thereby reach the purpose of this utility model.

Fig. 4, be the utility model user mode synoptic diagram.
Fig. 5, for the utility model structural representation cut-open view (recessed joint is circular shape).
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the utility model 100 comprises transmission basal layer 10, be arranged at the transparent gum layer 20 of transmission basal layer 10 bottoms, be incorporated into the outer release liners 30 of transparent gum layer 20, be incorporated into the intermediate diffusion layer 40 of transmission basal layer 10 tops and be incorporated into the transparent protective film 70 of intermediate diffusion layer 40 end faces.
Transmission basal layer 10 is for having any form basic unit of transmission translucent effect, and it can be with white PET plate, and it is used the required chromatograph white of modulation concentration and controls its optical concentration.
Transparent gum layer 20 can be for sticking in the body surface of using, on various liquid crystal (LCD) display panel, scanner; And by being incorporated into the outer release liners 30 of transparent gum layer 20, at ordinary times not the time spent it is shielded, during use, only need simply tear off this release liners 30 promptly for use.
As shown in Figure 3, Figure 4, the intermediate diffusion layer 40 that is incorporated into transmission basal layer 10 tops has the printing opacity of any form or transparent PC sheet, its single or double is formed with the series of the some any forms that form in running roller roll-in mode for light transmission diffusion roll line 50 and recessed joint 60, promptly with the roller line 50 of roll mould lines formation and the form of recessed joint 60.Make intermediate diffusion layer 40 surface atomizings with fine and closely woven roller line 50 and recessed joint 60, and according to required fogging degree, the density that dancer rools line 50 and recessed joint 60 are different.And be provided with a curved portions 61 that supplies light source transmission radian not limit in recessed joint 60 bottoms at least, thereby reach the effect that makes even transmission of light and diffusion.
The transparent protective film 70 that is incorporated into intermediate diffusion layer 40 end faces is for using the jettisonable clear plastic sheet on protection intermediate diffusion layer 40 surfaces.
As shown in Figure 5, also can make the recessed joint 60 ' that forms on the intermediate diffusion layer 40 be circular shape, and the curved portions 61 ' of recessed joint 60 ' bottom also relatively is circular shape, uses the effect that increases light transmission and diffusion.
As mentioned above, the utlity model has following advantage:
1, light transmission, diffusion evenly promptly can make the utility model 100 integral body have uniform transmission and diffusion effect by roller line 50 and recessed joint 60 (60 ').
2, roller line 50 can be regulated different density and produce different fogging degrees according to the utility model 100 is required, has remedied the deficiency that known techniques can't be regulated.
3, can increase the light diffusion effect,, form as the reinforcement optics diffusion effect as the lens by the curved portions 61 (61 ') of recessed joint 60 (60 ') bottom.
4, the surface does not have and peels off or the scratch damage, thereby significantly improves product quality; And produce even roller line 50 and recessed joint 60 (60 ') by the roll-in mode, thereby its surface is not had peels off, the foeign element of scratch, crawling or the influence of other manufacturing process in manufacturing process, to reduce the fraction defective of product.
5, processing is easy, cost is low and pollution-free.
