LED scroll the display screen to move the movable LED car display

LED scrolling display 13992889963 movable LED screen mobile car display system configuration of the screen by a computer controlled system supports IBM - PC compatible machine and various types of system software and user software, and specially equipped with the following specific software: 1. Chinese Win2000, WinXP, operator interface. 2. Video Control Software LedshowTW Super 3. screen playback control software LEDSHOW. 4.3D animation software product quality selection of raw materials is a prerequisite for 2.6 quality of the original device. Our LED display of key raw materials are imported devices. 1, the power supply module inside the power supply circuit has a very high demand, in addition to the voltage to stabilize, but also requires anti-interference ability, with a variety of protective measures. Characteristics of the switching power supply to meet our requirements. We use swatow or joint creation of high-quality products, the long-term use of its performance and reliability to meet the design requirements. With Cl-A-200-5, for example, its performance parameters are as follows: Input voltage 90 ~ 132VAC / 170 ~ 264 VAC Input Frequency 47-63Hz Output voltage DC5V (+ 10% ADJ) Output Overload 110-150% Output overvoltage protection 115% ~ 150% of input to output voltage test: 3KV AC / 1min input to ground: 1.5 KV AC / 1min opening time 50ms (typ.) Hold time 20ms (typ) Operating temperature -10 ~ + 50 Storage Temperature - 20 ~ + 85 MTBF time> 50,000hours heat dissipation from the cold 100% load aging, over-voltage, over current and short circuit protection of the seed supply has the following features: ● voltage stability, strong anti-jamming capability, small ripple load dynamic range. ● with overvoltage protection, overcurrent protection and inrush resistance to impact, strong adaptability to the environment on the grid. ● With 150% of design capacity. ● Small size, light weight. 2, other devices ● drive circuit: The United States 595, eliminating the mosaic, stable performance, high reliability, can effectively ensure the consistency of the brightness of the display. ● Control circuit: The United States Lucent controller chip 2C04, high integration, good stability. ● driver board: UL standards, Shenzhen production lines MILL. ● Control circuit board: UL standards, Shenzhen pcb production ● various connectors: Imported ● communication lines: the five communication lines (if the communication distance is greater than 120M shall fiber) ● Crystal: Imported 3, unit case production process ※ characteristics of the surface portion of the metal frame metal frame surface must be corrosion, water treatment: Specifically as follows: ① the metal surface sandblasting, play a rust role. ② in metal surface treatment with zinc oxide 锓 ensure decades stainless rot; ③ spray zinc oxide during the processing, the reprocessing in surface spray. ④ Finally, the surface is coated with anti-acid resin shoe processing, and more effectively prevent atmospheric corrosion. ※ In the overall structure of the measures in the rear of the big screen have enough space, minimizing the temperature of the atmosphere. Were the four treatment measures, the moisture of the display, corrosion problem will have been solved. The entire screen structure is as follows:
