The V-shaped groove 4 can of course also be understood as a tine. The V-shaped grooves 4 can enhance the light diffusion effect and can replace the original optical cement as the bonding between the optical film 5 and the glass substrate 1.
A manufacturing method of a non-optical adhesive full-lamination glass diffusion plate comprises the following steps:
step 1: covering a layer of UV ink on the front surface of the glass substrate 1 by printing or ink-jet, and using the exposure of 200mj/cm at 160 DEG C2The UV light is continuously irradiated for 10 minutes, and a semi-solidified UV ink layer A is obtained on the front side of the glass substrate 1;
