Light Guide Plate Manufacturers Will Explain To You Which Is Better, Silk-printed Light Guide Plate Or Laser Light Guide Plate?

The first one is technically speaking. Silk screen and laser engraving are based on the principle of optical refraction or reflection, so both silk screen and laser engraving light guide plates use the same optical principle. If the design is reasonable, both silk screen and laser technology can achieve good brightness. And uniformity effect.

Second, from the perspective of environmental protection. If the product is for export, then the first choice is the laser light guide plate. Foreigners have always paid more attention to environmental protection. The volatilization and light decay of silk screen printing ink directly rise to environmental protection problems. Especially the maintenance costs in the later period are headaches that many export companies need to explain to their customers. Therefore, the laser light guide plate There is no such worries about physical molding. Manufacturing process: Laser engraving. The laser engraving production method is to use a computer to strictly control the energy of the laser head and the position of the laser head according to the program requirements, and use vaporization to depict a microstructure array with a certain size on the back of the light guide plate. This method It can precisely control the depth of the scattering structure, but the efficiency is very low and it is not convenient for mass production.

Third, from a cost perspective. The cost point of view is a major focus of the market. The price of screen-printed light guides is significantly lower than that of lasers. From the gradual emergence of laser light guides in the market in 2012, it can be known that the cost of light guides of the same specification is one higher than that of silk-screened light guides. Times, even if the current price of laser light guide plates has dropped to a similar level, the price of laser light guide plates is still slightly higher. If large quantities are produced, manufacturers will directly choose silk-screen light guide plates to avoid excessive costs. What needs to be paid attention to when buying LED light guide plate lamps. With the development of society, the living standards of the people are gradually improving.

Fourth, from the perspective of the application market. The technology of silk-printed light guide plate is not as fast as that of laser light guide plate. The current market uses silk-printed light guide plate in light boxes. On the contrary, laser light guide plate has begun to increase the application market of end products, especially exported to the European and American markets.
