Show the image quality of device.
In order to improve reflectivity, generally by adding particle or reflectance coating being made to generate micropore or bubble, the folding of particle is utilized
It penetrates or the refractive index difference between the substrate resin and micropore or bubble of film improves reflectivity, although these methods can improve film
Reflectivity, still, with the raising of the porosity in reflectance coating so that reflectance coating soften, cause reflectance coating using process
It is easy to scuffing, wrinkle in the process, influences brightness and the image quality of backlight and display.
In recent years, with the continuous development of the liquid crystal displays industry such as telecomputer, the performance of reflectance coating is also constantly proposed
High requirement.In order to make reflectance coating possess higher reflectivity, the following method of generally use：A. it is added in PET polyester films
The inorganic particulates such as sour barium utilize the hole at the interface and the small hole generated by core using particle of PET polyester and inorganic particulate
The method that hole interface carries out light reflection；B. be added in PET polyester films the resin incompatible with polyester and using its as karyomorphism at
Small hole, the method for carrying out light reflection using this hole interface.But PET polyester films processing and forming is difficult, molding temperature
Height, the production cycle is long, and impact property is poor, the shortcomings of causing film embrittlement.
And the original processing scheme of backlight industry be there is base material transparent double face glue and ESR reflector plates individually to process then
Single product is assembled apart together again.Cumulative limit is big when doing so assembling product, inefficient low output, deficient manufacturing procedure.Have
Base material double faced adhesive tape and reflector plate are individually processed, and process materials increase, and overall cost increases.
