¿Qué tipos de guías de luz existen?
Mar 05, 2022
The well-chosen light guide plate is widely used in the market as a high-tech process material that does not absorb light and has strong reflection efficiency, but the price of the light guide plate in the market is not the same. In fact, this is due to the different craftsmanship of the light guide plates, which fundamentally leads to the difference in their prices. But what types of light guide plates are popular among customers?

1. Placa de guía de luz de fotolitografía
The photolithography light guide plate is a kind of board obtained by processing silicon wafers by photolithography technology. Of course, in order to guide the light of the silicon wafers, it is not only necessary to choose a flat and non-dented silicon wafer, but also to coat a layer of corrosion-resistant silicon wafers. photoresist, and put it under strong light to make it by photolithography. Since the lithography light guide plate is made on the lithography plate by strong light, it can be selectively exposed by controlling the production layer pattern of the strong light, which means that the relevant graphics can be produced according to the needs of customers. , more optional than the general light guide plate shape.

The laser engraved light guide plate is a kind of board that is more common in the market and has a higher sales volume. This is because it is a kind of board that is precisely operated by a computer, which means that it can strictly control the board through a computer program. , both the energy emitted by the laser head and the position of the laser head can be accurately described. This vaporization method can depict a microstructure array with a certain size on the back of the light guide plate. Compared with other types of light guide plates, this type of light guide plate can precisely control the depth of the scattering structure, and the light guide performance is comparable. Comparatively speaking, it is also a better one.
