Made of optical grade acrylic (PMMA) / PC as the base material, using the backlight module technology of LCD display screens and notebook computers, through the high light conductivity of the light guide points, and calculated by a computer for the light guide points, the light of the light guide plate is refracted into a surface light source in a uniform light state and formed. The product is made by combining the principle of spectral analysis and digital UV printing technology and under the environmental conditions of constant temperature, constant humidity and dust-free.

[0003] The existing light guide plate structure is usually a single plate made of optical grade acrylic (PMMA) / PC material. Due to unreasonable design, it has the following disadvantages: 1.
