Analysis of the characteristics of vehicle-mounted LED display screen

Vehicle-mounted LED display screen is a product that uses LED technology, GSM/GPRS technology, low temperature technology, anti-static technology, anti-interference technology, vehicle-mounted electronic technology, etc. to display information on mobile cars. It is different from ordinary LED display screens installed in fixed places. Features of vehicle-mounted LED display screen:

1) High stability and reliability. Cars are always moving, and the stability and reliability of electronic products are very high.

2) High stability and reliability. Cars are always moving, and the stability and reliability of electronic products are very high.

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

4) Good anti-static measures. Cars are prone to static electricity during operation, especially in autumn, when the static high voltage can reach thousands of volts. If there are no good anti-static measures, it is easy to damage ICs and LED lights.

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

6) LED brightness attenuation: LED attenuation characteristics: LED brightness is attenuated, with a decay rate of 10-70% in a year. If the quality is poor, the brightness will be reduced by half in half a year, making it impossible to see the displayed content clearly.
