LED displays are more and more widely used in life and play an increasingly important role
The reason why the LED display has been widely valued and developed rapidly is inseparable from its own advantages. These advantages are summarized as: high brightness, low operating voltage, low power consumption, large size, long life, shock resistance and stable performance. The development prospect of LED is extremely broad, and it is developing in the direction of higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, reliability and full color. LED displays are widely used in sports venues, commercial applications, banks, securities, postal services, docks, shopping malls, stations, postal services, telecommunications, institutions, monitoring, schools, restaurants, hotels, entertainment, and other outdoor advertising and publicity, 2013 In 2019, UNILUMIN of the Russian Universiade used Umesh25 building screen to broadcast the picture smoothly and delicately in real time.
The static scanning technology adopts the static latch scanning method, high-power drive, and fully guarantees the luminous brightness. The automatic brightness adjustment has the automatic brightness adjustment function, which can obtain the best playback effect in different brightness environments. There are also drawbacks, that is, on rainy days, the LED display screen will be soaked by the rain, and people's eyes will easily induce eye diseases and tears when they face the display screen for a long time. Environmental protection technology should fully consider the impact of light on people's spirit, and do not pursue brightness too much.
