LED luminous color and luminous efficiency and production of LED materials and processes related to the beginning of all light blue ball, plus phosphor back, depending on the needs of the user to adjust the different light color, red is widely used , green, blue, yellow four. Because LED low voltage (only 1.2 ~ 4.0V), capable of self-luminous and have a certain brightness, brightness and can adjust the voltage (or current) p10 monochrome screen, which in turn impact resistance, anti-vibration, long life (100,000 hours ), so the large display device, there is no other way to display and LED display match. (1) by the use of the environment is divided into indoor, outdoor and semi-outdoor Indoor screen area is generally from less than 1 square meters led to more than a dozen electronic monochrome screen, indoor LED display used in the indoor environment, such a display brightness moderate, viewing angle, color mixing from the past, light weight, high density monochrome screen, suitable for relatively close viewing. Outdoor screen area is generally from a few meters to tens or even hundreds of meters, the point density than the thin (mostly 2500-10000 points per square meter), brightness in 5500-8500cd / square meter (toward different requirements of different brightness) can be in the sun direct conditions, viewing distance of tens of meters outside the screen body has a good wind resistance to rain and lightning protection capability. Semi-outdoor screen between both outdoor and indoor, with high brightness led luminous monochrome screen manufacturers, in the case of using a non-direct sunlight outdoor screen body has a certain seal, usually under the eaves or in the window. Sichuan led monochrome screen _ Yasuhiro photovoltaic (certified) _ monochrome screen provided by Linyi Wang Tai Electronics Limited. Linyi Wang Tai Electronics Co., Ltd. (www.ledzkd.com) (www.ledzkd.com) is a leader in Linyi, display devices, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. In Hong Thai Optical leadership with the staff warmly welcome all inquiries negotiations to create the Thai macro photoelectric a better future.
