Car LED display is the use of led technology, GSM / GPRS technology, low temperature technology, anti-static technology, anti-jamming technology, automotive electronics technology in the mobile car display information products. It is different from the ordinary LED display installed in a fixed place. The reason lies in the car and advertising.
Car Features:
1) the car is always moving, the stability of electronic products and reliability requirements are high.
2) the car is powered by the battery, the car in the start, brake, stop will have a high pulse voltage, if the power supply system is not good, it will burn the display.
3) The car is usually placed outdoors in the north. Winter temperatures may reach -40 ° C and summer temperatures may reach 60 ° C, which requires power and display components to operate at wide temperatures.
4) The car is prone to static electricity during operation, especially in the fall electrostatic pressure can reach thousands of volts, if there is no good anti-static measures, it is easy to damage the IC and LED lights.
5) the appropriate brightness, LED display if the brightness is not enough, can not see during the day, lost the meaning of the installation of the display; if too bright affect the traffic.
6) LED attenuation characteristics, LED brightness is attenuation, in a year which has 10-70% attenuation rate, poor quality half year brightness reduced by half, resulting in can not see the display.
7) There are other dimensions and so on.
