Embodiment 1

[0037] ① Raw material preparation: See Table 1 for the weight percentage of each raw material of the light-diffusing coating, wherein the particle size of PMMA particles is 1-2 μm, the particle size of PBMA is 7 μm, and the particle size of PS is 3 μm;

[0038] ②Light diffusion coating configuration: first, cyclohexanone, butyl acetate, ethyl acetate, polyether modified polydimethylsiloxane, leveling agent, dispersant, poly-n-butyl methacrylate (PBMA), Add polystyrene (PS) and PMMA particles into the disperser to disperse for 20-30min at a stirring speed of 1600rpm / min, then add acrylic resin to disperse for 15-20min at a stirring speed of 800rpm / min, and finally add aliphatic polyisocyanate to disperse for 15-20min. The stirring speed is 800rpm / min, and the light-diffusing coating is obtained;

[0039] ③Front coating: Apply the light-diffusing coating prepared in step ② evenly on the PET carrier layer (the haze of the PET carrier layer is below 2.5%, and the light transmittan...

Abstract

The invention relates to the field of electronic product manufacturing, in particular to an optical composite membrane and a manufacturing method of the optical composite membrane. The optical composite membrane comprises a PET carrier layer, an upper diffusion membrane layer formed by coating of light diffusion coatings is arranged on the front face of the PET carrier layer, a light increasing membrane layer formed by coating of ultraviolet light polymerization acrylic resin is arranged on the back face of the PET carrier layer, and a protection membrane layer is compounded to the outer surface of the light increasing membrane layer. The light increasing membrane layer enables light to be amplified, the light brightness is improved, the light becomes softer, the hardness of the surface is increased, and therefore the optical composite membrane is not prone to being damaged by other components.

Description

technical field [0001] The invention relates to the field of electronic product manufacturing, in particular to an optical composite film and a preparation method thereof. Background technique [0002] As an important part of the information industry, the flat panel display (FPD, such as LCD, PDP, etc.) industry has developed rapidly in recent years. Flat panel displays are widely used in TVs, computer monitors, notebook computers, mobile phones, digital cameras, MP3, MP4, MP5, car DSC / DV, GPS navigators and other products. However, these flat panel displays do not emit light themselves, and the light source for the generated picture is provided by the backlight module, and the light source requires uniformity and high brightness. [0003] Whether it is the LED backlight that is widely used now or the traditional CCFL backlight, the light emitted by it is a point light source or a line light source, not a surface light source. But through the diffusion film used in the bac...
