Domestic LED display in the factory will be aging (grilled machine), the LED lights will repair and replacement pixel runaway, "the whole screen pixels out of control rate" within 1/104 of control "region pixels runaway rate" control it is no problem within 3/104 of Zigui LED electronic display, and even some individual manufacturers of enterprise standards before leaving the factory is not allowed out of control pixels, but this is bound to increase the manufacturer's manufacturing maintenance costs and extend the shipping time. In different applications, the actual requirements of the pixels out of control rate can have large differences, in general, LED display LED electronic display for video playback, the indicator within 1/104 of control is acceptable Yidu LED electronic display, is to be achieved; simple character information dissemination, the indicator is controlled within 12/104 of rational consumption and power requirements Light maximum power consumption is started or full light if used for extreme power consumption when the situation when the male LED electronic display, the maximum power consumption is a factor AC power supply (diameter, switches, etc.) must be considered. The average power consumption is generally the maximum power consumption of 1/3. LED Strip switching power is very important, mainly divided constant current power supply, constant voltage power supply; AC220V input, DC12V output, DC24V output, DC36V output, DC48C output. LED power supply, it can be divided into rain power, non-waterproof power supply, water supply; Yichang LED electronic display _ 金锐光 electricity (certified) _LED electronic display provided by the Science and Technology Co., Ltd. Yichang 金锐光. Yichang Jinrui Guang Technology Co., Ltd. (www.ycjrgd.com/) Hubei Yichang, electronic, electrical project co-leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs .
