The car bar LED display is a bar LED display that uses LED technology, GSM/GPRS technology, low temperature technology, anti-static technology, anti-interference technology, vehicle electronic technology, etc. to display information on mobile vehicles. It is different from fixed places. Installed ordinary strip LED screen.

Features of car bar LED display:

1) The car is always moving, which requires high stability and reliability of electronic products.

2) The power supply on the car is powered by the battery. The car will generate a high pulse voltage when it starts, brakes and stops. If the power supply system is not good, the display screen will be burned.

3) In the north, cars are generally placed outdoors. The temperature may reach -40°C in winter and 60°C in summer, which requires the power supply and display components to work in a wide temperature range.

4) The car is easy to generate static electricity during operation, especially in autumn, the high voltage of static electricity can reach thousands of volts. If there is no good anti-static measures, it is easy to damage the IC and LED lights.

5) Appropriate brightness, if the brightness of the LED display is not enough, it will not be visible during the day, and the meaning of installing the display will be lost; if it is too bright, it will affect the driving.

6) LED attenuation characteristics, LED brightness is attenuated, with a 10-70% attenuation rate in one year, and the brightness of poor quality is reduced by half in half a year, making it impossible to see the display content.

7) Others include appearance size and so on.
