"Low light high ash" is a prerequisite to ensure viewing comfort, Shandong led display, users in the purchase of a small pitch brightness LED product is the primary concern. In traditional LED display technology, indoor led display, lower the screen brightness can cause loss of gray, and gray will directly affect the loss of picture quality, color led display, therefore, an important quality small pitch judgment Standard is to achieve "low light high ash" technical indicators. LED luminous efficiency (that is, external quantum efficiency) is within the LED quantum efficiency and the escape rate decision. Today, LED internal quantum efficiency is as high as 90%, but due to the low escape rate, Liaoning led display, external quantum efficiency and therefore improve LED light efficiency has become a bottleneck. In order to break the bottleneck restricting the development of the industry, many innovative solutions have been proposed, but the theory has been verified, most of which have entered the test phase, and some have been successful, and has laid a solid foundation for the eventual industrialization. Shandong led display, led display, Liaoning, Gao Jin photoelectric provided by Jinan Optoelectronics Technology Co., Ltd. Gao Jin. Jinan Gao Jin Optoelectronics Technology Co., Ltd. (www.gjlled.cn) strong, credible, in Jinan, Shandong liquid crystal device industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Gao Jin photoelectric and you hand into the brilliant, for a better future!
