Comparison of several commonly used light guide plate application technologies for led ultra-thin light boxes

  LED ultra-thin light boxes have been increasingly favored by the advertising industry. The development trend of advertising light boxes is also promoting the appearance, lightness, energy saving and high efficiency of ultra-thin light boxes . Now I use the light guide plate technology used in the ultra-thin light box on the market to analyze and analyze the following. I hope I can help you.

First, laser management (the world's leading technology - the company adopted): by Shenzhen Yingxing Technology Co., Ltd. optical doctor according to the working experience of the world laboratory of multinational companies, combined with the needs of the actual product for in-depth research and development, through the light transmission and attenuation The study of the curve, master the equation for solving the optimal parameter combination, and derive the optimal solution, so as to achieve the correct setting of dozens of parameters of the laser machine. Light guide plate fabrication of any width and size is possible. The application limit of this technology lies only in the performance of the laser machine, not in the technical principle. At present, the technology is only available to the company and is applying for related patents.

Second, the laser engraving (there are technical defects) : can not completely overcome the law of light conduction and attenuation curve, can not solve the optimal parameter combination equation, can not derive the optimal solution, can only obtain limited parameter values ​​by experience and repeated testing. No matter what kind of precise laser machine is used, the real uniform light guide plate can not be realized, and only a limited uniform light effect can be achieved.

Third, screen printing (there are technical defects): the ink is easy to oxidize, the light guiding life is short, generally not more than 2 years, under the condition of poor heat dissipation of the lamp tube, the oxidation is accelerated and the life is shorter. The technical principle is similar to laser engraving, and the technical defects are similar. Therefore, no matter how the screen model is customized, the real homogenizing light guide plate cannot be realized, and only a limited uniform light effect can be achieved.

4. Nano-light guide (there are technical defects): The ability to overcome the light conduction attenuation curve is weaker than screen printing, and it is almost impossible to set any light guiding parameters, so the light guiding effect is even worse. A slightly larger size cannot be realized. Accepted uniformity effect.
