1. The development process of Acrylic light guide plate
Since the 1990s, with the continuous development of science and technology, the production method of light guide plates has been gradually improved, resulting in different and earlier printing production. In contrast, we call it "non-printing".
Injection Molding
It fills the molten molding material into a closed mold under high pressure, which requires the light guide plate and the microstructure to be completed simultaneously in injection molding, and the mold must be made quite strong, so the price of the mold is also quite expensive, so it must be Mass production in order to offset the high mold costs. The single-sided microstructure array light guide plate generally adopts the injection molding process, and its bottom texture structure can be in the shape of a micro lens, a microsphere or a tetrahedral corner prism shape.
photolithography
The lithography technology is to coat a layer of corrosion-resistant photoresist on a flat silicon wafer, and then let the strong light pass through the lithography plate, and selectively expose on the lithography plate according to the pattern information of the specific layer produced; Then the developed photoresist is removed, and a film with a micro-patterned structure is left on the upper surface of the silicon wafer. The surface roughness of the light guide plate made by photolithography is not good, and the loss of light energy is relatively large.

3. Clear Acrylic Light Guide Plate Shape:
It can be arbitrarily cut into the required size, and can also be used by splicing, the process is simple and the production is convenient;
High light conversion rate (more than 30% higher than traditional boards), uniform light, long service life, can be used normally indoors for more than 8 years, safe and environmentally friendly, durable and reliable, and can be used indoors and outdoors;
Under the same area of luminous brightness, the luminous efficiency is high and the power consumption is low;
Can be made into special shapes, such as circles, ellipses, arcs, triangles, etc.;
Under the same brightness, thinner products can be used to save costs;
You can use any light source, point line light source for surface light source conversion, the light source includes LED CCFL (cold cathode lamp), fluorescent tube, etc.
4. What is the relationship between the acrylic light guide plate and the acrylic plate?
The light guide plate is made of optical-grade acrylic sheet, and then uses high-tech materials with extremely high reflectivity and no light absorption to print light-guiding points on the bottom surface of the optical-grade acrylic sheet with UV screen printing technology.
The main material of the acrylic light guide plate is optical acrylic plate. The quality of the acrylic light guide plates currently produced is also different due to the different processes of different manufacturers. In particular, although the price of the recycled board is cheap, it is easy to yellow and the light transmittance is also poor. The production of acrylic light guide plate should not be easy to yellow and transmit light. Transparent board with a rate of 92%-93%.
At present, the light guide plates on the market are made of two materials: acrylic sheet and PC sheet. However, the most common light guide plate is made of acrylic board material. There are fewer light guide plates made of PC board material, and they have to be specially customized, and not every manufacturer of light guide plates does it.
