The application of the bus led display add many convenience for our life. While what’s the main features of the bus led display? We can analyze it from the aspect of the lightness, power supply, safeguard procedures and so on.

1.LED brightness decay. The brightness of the bus LED display has the attenuating property. It has 10%-70% attenuation rate, so the bus led display with the poor quality will reduce 50% lightness within half year. Then we can’t see the display content clearly.

2.Stable power supply system support. The power supply on the bus is storage battery power supply. When the car start, brake and stop, it will generate a higher pulse voltage. It even can burn down the bus led display with the poor power system.

3.High stability and reliability. Because of the constant movement of the bus, it require a higher demand of the electronic products.
