A light guide plate manufacturing process TFT Display Module

In understanding the process should be preceded by understanding the parts and materials required for the light guide plate
1, the required materials and tools of the Ministry
a. Injection molding: Optical grade PMMA particles, ink
b. Crop: optical grade PMMA plates, inks

2, optical grade PMMA particles, flat: OLED Display Module
No matter what mode of production is produced out of the light guide its most important and original material optical grade PMMA (POLYMETHYL METHACRYLATE) (polymethyl methacrylate also known as acrylic or plexiglass, PMMA particles have their classification PMMA and PMMA plates extracted from petroleum monomer (MMA) and then the monomer (MMA) has been chemically processed to make optical grade PMMA particles (already available beginning with the injection molding), and then use optical grade PMMA particles casting method (Casting) or pressed out method (Injection) to produce optical grade PMMA plate, currently the industry recognized PMMA manufacturers are as follows: (Japan) Mitsubishi Rayon Mitsubishi Rayon, (Japan) Sumitomo Chemical Sumitomo, (Japan) Asahi Kasei Asahicasei, ( day) Kula Lei Kuraray, (Taiwan) Chi Mei Chemical, (Korea) World and Sehwa,
3, Ink: divided into two kinds of UV and IR
4, making way for the light guide plate cut three parts:
The first is the acrylic plate shape processing;
The second is a stencil production;
The third is printing, the process flow, respectively
a. acrylic cut the original plate contouring => Mirror planed> forming.
b. stencil production = Net Design> Film Output> stow net
c. printing = acrylic wash> Printing> Baking (IR) or ultraviolet light (UV)
5, injection molding light guide is divided into print and non-print type two, which is basically the same process as in the casting mold Printed in the injection will not cast on the network, so the only shot of the finished acrylic shape, and then after printing is completed until forming the light guide plate, rather than printing style is designed outlets cast in the mold, so that the outlets in the injection molding of the light guide plate simultaneously. graphic lcd 128x64
