Zweig optical LED display The reason why widespread attention and rapid development, is that it itself has the advantage inseparable. They sum up these advantages are: high brightness, low voltage, low power consumption, large-scale, long life, impact resistance and stable performance. LED is extremely broad prospects for development, is moving higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability, full color direction. LED displays are widely used in sports stadiums, business applications, banking, securities, postal services, terminals, shopping malls, railway stations, postal services, telecommunications, institutions, monitoring, advertising schools, restaurants, hotels, entertainment, and other various outdoor places, 2013 Russian Universiade UNILUMIN buildings using Umesh25 screen broadcast live picture smooth and delicate. Existing on the LED screen market LED die are: Nichia, Opto, Showa denk, the United States CREE, Swaziland, Taiwan wafer and some domestic dies. Nichia, CREE die is the most mature, but high overall cost; Opto Taiwan, Hangzhou Silan die technology is mature and relatively cheap; other domestic manufacturers to die, although cheaper, but technically perfect. Division I according to the current domestic LED market is generally recommended customers to use high cost of Opto, Swaziland, wafer die. And in the conditions required customers can expatriate engineer site visits, over the years we have provided a good cost-effective full color display for many dealers and engineering companies, products, because viewing angle, color uniform, easy to die light low failure rate, easy maintenance advantage praise of the market!
