FAQs

What are the installation requirements of the LED display screen?
Power supply: the power supply connector must be match for the size of the LED display screen.
220V electricity power supply, live wire, neutral/null wire and the earth wire.
380V electricity power supply, three live wires, neutral/null wire and the earth wire.
The intercept area of the live wire is the same as the null.
The LED display screen above 0.1 million KW must have the lower-voltage equipment.
Communication requirements: the communication distance is decided by the length of the communication wire.
The communication wire must be installed under the length standard of the communication wire of the corresponding LED display screen.
What are the considering factors of the Outdoor LED display screen?
Main questions of outdoor display as below:
(1)display installed in the outdoor, solarization and drench, blow and dust, bad working environment, electrical equipment being wringing and damp will cause short circuit, even fire, cause conk out, even fire, result in loss.
(2)the display may be attacked by the strong electromagnetism made by the thunder and lighting.
(3)The big change of the environment temperatures. The Operating LED display will emit a lot of heating, if the environment temperature is too high, the molectron of the LED screen maybe operating un-normally to damage for its bad giving heating out, finally the LED display system will not operate normally as usual.
(4)The display has a wide range of angle, long viewing distance, big change of the environment light, especially the direct to the sunshine.

With these special requirements, the outdoor LED displays needed:
(1) The parts connecting the body of the LED display with the building must be waterproof and anti-leaking strictly as the display. The display must have the measurements for water giving out. Once leaked, it will be given out smoothly.
(2) The lightning rod should be installed on the LED display or the building. The body and the frame of the display must to keep connecting with the earth, the resistor of the earth wire should under 3 Q , so as to the heavy current from lightning can be discharged in time.
(3) Install the ventilator equipment to lower the temperature, keep the inner cabinet temperature in the range of -10 ~ 40 centigrade degree. The back top of the display must install the rolling electronic fans to give the heating out.
(4) Choose the industrial using IC with the working temperature range of -10 ~ 40 centigrade degree for fear the LED display can not start in the low temperature of the winter.
(5) To be seen form a long distance in the high brightness environment, it must be using the extra high brightness LED lamps.
(6) Choosing the new large angle LED lamps as medium, the LED display will have a larger angle, vivid colors, consistent operation and a long life of more than 100 thousand hours. The medium has a popular package with the hat-edge and square shape in cylinder, sealed by Silicon glue, assembly without metal. Also the display has an unique exterior outface, solid and durable, has the characteristics of anti-dazzle, waterproof, impurity proof, protection from high temperature and short circuit.
