Abstract
The invention discloses the light diffusing sheet that a kind of light resistance is stable, including transparent base plate, the one side of the backing material plate is coated with resin bed, the another side of the transparent base plate is coated with transparent nano-material coating, it has preferable light transmittance, and light diffusion effect can be made evenly, it can effectively lift the competitiveness of product.The present invention is simple in construction, reasonable in design, by the part reflection function of the fluorescent grain, light intensity can be made further to be scatter and be spread uniformly compared with the light of strength, avoid the generation of the bright shadow of light source, therefore above-mentioned diffusion sheet light has the advantages of light diffusion effect is strong.
Description
Technical field
The present invention relates to blooming piece technical field, and in particular to a kind of stable light diffusing sheet of light resistance.
Background technology
Liquid crystal display device is widely used in personal digital assistant, notebook computer, digital camera, mobile phone, liquid
In the electronic products such as brilliant TV.But because liquid crystal display device is non-spontaneous photosensitiveness, therefore it is needed by backlight module
Display function can be produced.
Because light source is generally spot light or line source, and backlight module is the display effect for reaching brightness uniformity needs to use
Area source, therefore spot light or line source will be converted into area source by backlight module by light diffusion element.This kind of light diffusion
Element is generally diffusion sheet.Traditional diffusion sheet diffusion effect is bad, in use the life-span do not grow.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple and reasonable, and practicality is good, and light resistance is stable
Light diffusing sheet.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of stable light diffusing sheet of light resistance, including transparent base plate, the one side of the backing material plate are coated with resin bed, institute
The another side for stating transparent base plate is coated with transparent nano-material coating, and it has preferable light transmittance, and can spread light
Effect evenly, can effectively lift the competitiveness of product.
Further, the nano material in the nano-material coating is formed using the nano material of two kinds and the above.
Further, the resin bed is one or a combination set of acrylic resin, acrylic-amino resin, epoxy resin.
Further, the nano-material coating is not easy coated on transparent substrate surface by the way of electrostatic spraying
Come off, quality is good.
The cutting method of above-described light diffusing sheet, comprises the following steps：The backing material plate and cutting knife of the light diffusing sheet
It is oppositely arranged, the cutting knife is above backing material plate toward layer side resin to cutting.
The beneficial effects of the invention are as follows：The present invention is simple in construction, reasonable in design, reflects work(by the part of the fluorescent grain
Can, light intensity can be made further to be scatter and be spread uniformly compared with the light of strength, avoid the generation of the bright shadow of light source, therefore above-mentioned expansion
Discrete piece light has the advantages of light diffusion effect is strong.
Brief description of the drawings
