The reflection process is very complicated and important. The different indexes such as reflection intensity, spectrum, angle and so on are different. Different projectors Inconsistent performance in the color reproduction, contrast, image details vary, which is the main reason that the screen is difficult to choose. Therefore, the current guide to consumers is often the brand, the price and the recommendation of the business rather than the actual performance, let alone
