Specific embodiment

Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.

Fig. 1 schematically illustrates a kind of structural schematic diagram of PET light diffusion release film provided by the utility model, such as schemes Shown in 1, including PET base 4, it further include two protective layers, 1, two PET release layer 2 and two light diffusion layers 3；Two light diffusions Layer 3 is symmetrical and fixes the upper and lower surface for fitting in PET base 4 respectively；PET release layer 2 is symmetrical and fixation is fitted in On each surface of the light diffusion layer 3 far from PET base 4；Two PET protective layers 1 it is symmetrical and respectively it is fixed be fitted in each PET from On surface of the type layer 2 far from light diffusion layer 3；In order to become apparent from the structure of inverted pyramid groove 31, Fig. 2 schematically illustrates this The structural schematic diagram for the light diffusion layer that utility model specific embodiment provides, as shown in Figure 2；On light diffusion layer 3 and lean on The side of nearly PET release layer 2 is equipped with several inverted pyramid grooves 31.

Specifically, a kind of PET light spreads release film, including PET base 4, further include two protective layers, 1, two PET from Type layer 2 and two light diffusion layers 3；Two light diffusion layers 3 are symmetrical and fix the upper and lower surface for fitting in PET base 4 respectively； PET release layer 2 is symmetrical and fixation is fitted on each surface of the light diffusion layer 3 far from PET base 4；Two PET protective layers 1 It is symmetrical and respectively fixation be fitted on each surface of the PET release layer 2 far from light diffusion layer 3；On light diffusion layer 3 and Several inverted pyramid grooves 31 are equipped with close to the side of PET release layer 2；By the way that 3 surface of light diffusion layer is arranged to inverted pyramid 31 structure of groove, densely distributed due to 31 structure of inverted pyramid groove, light is on 31 surface of inverted pyramid groove by multiple Reflect up to light diffusion effect.

Optionally, the contact area between increase level is preferably bonded between realization level, on PET release layer 2 and leans on The surface of nearly PET protective layer 1 is equipped with round tongue 11；Surface on protective layer 1 and close to PET release layer 2 is equipped with circular groove 21；Round tongue 11 is adapted with circular groove 21.
