The light guide plate is one of the important components of the liquid crystal display. When light is coupled into the light guide plate from the side, the microstructure on the surface of the light guide plate will change the propagation path of the light, so that the light is uniformly emitted from the light guide plate's light exit surface, so the microstructure on the light guide plate surface The structure is the key to achieve uniform light emission. I’d like to expand on light guide plates to help you have a better understanding of light guide plates.
Here is the list of the article:
l How to classify the light guide plate?
l What are the characteristics of the light guide plate?
l How to buy light guide plates?
By shape
Flat plate: The light guide plate is rectangular when viewed from the point of light incident.
Wedge-shaped plate: One side of the light guide plate is thick and the other is thin into a wedge (triangular) shape from the point of light incident.
By outlet
Printing: After the light guide plate finishes the shape processing, the dots are printed on the reflective surface by printing, which is divided into IR and UV.
Non-printing type: The dots are directly formed on the reflective surface when the light guide plate is formed. It is divided into chemical etching (Etching), precision mechanical characterization (V-cut), photolithography (Stamper), and internal diffusion.
Follow the light
Side light type: Place the luminous body (tube or LED) on the side of the light guide plate.
Direct type: Place the luminous body (tube or LED) under the light guide plate.
Press forming
Injection molding: Use an injection molding machine to inject optical grade PMMA particles into a mold at high temperature and high pressure to cool and shape.
Cutting and forming: The optical grade PMMA original board is cut to complete the finished product.
The light guide plate has many advantages.
1) The light guide plate can be arbitrarily cut to the required size, and can also be spliced and used, with simple process and convenient production;
2) The light guide plate not only has high light conversion rate but also uniform light, and has a long service life. It can be used normally for more than 8 years in the room. It is safe and environmentally friendly, durable and reliable.
3) Under the same area of luminous brightness, the light guide plate has high luminous efficiency and low power consumption;
4) The light guide plate can be made into special shapes, such as circles, ellipses, arcs, triangles, etc.;
5) In the case of the same brightness, the light guide plate can use thinner products to save costs;
6) The light guide plate can use any light source, and point-line light source can be used for surface light source conversion.
