Method for manufacturing light guide plate of tablet computer
Feb 24, 2021
The tablet light guide plate is made by using injection molding to press propylene into a smooth surface plate, and then use a material with high reflection and non-light absorption, and use a high-reflectivity and non-light-absorbing material on the acrylic plate, on the bottom of the light guide plate Use a laser engraving machine to mark a circular or square diffusion point. When the light hits the diffusion point, the reflected light will diffuse at various angles, and then destroy the reflection conditions and shoot out from the front of the light guide plate, using a variety of dense, different sizes The diffusion point can make the light guide plate emit light evenly.
The purpose of the reflector is to reflect the light exposed on the bottom surface back into the light guide plate to improve the efficiency of light use.
The main material of the light guide plate of the tablet computer is PMMA (acrylic or organic glass).
The manufacturing methods of the light guide plate of the tablet computer include:
1. Professional CNC engraving, as mentioned above, the tablet light guide plate engraves many concave or convex spherical surfaces to reflect and refract light.
2. Mold making.
