Vehicle-mounted LED displays are products that use LED technology, GSM/GPRS technology, low-temperature technology, anti-static technology, anti-interference technology, vehicle-mounted electronics technology, etc. to display information on mobile cars. It is different from ordinary LED displays installed in fixed places. The reason is in-car and advertising.
Features of vehicle LED display:
1) High stability and reliability
Cars are always moving and have high requirements for the stability and reliability of electronic products.
2) Stable power system support
The power supply in the car is powered by the battery. When the car starts, brakes and stops, it will generate a high pulse voltage. If the power supply system is not good, the display screen will be burned.
3) Wide operating temperature range
In the north, cars are generally placed outdoors. The temperature may reach -40°C in winter and 60°C in summer, which requires power supply and display components to work in a wide range of temperatures.
4) Good anti-static measures
It is easy for cars to generate static electricity during operation, especially in autumn. The high voltage of static electricity can reach thousands of volts. Without good anti-static measures, it is easy to damage ICs and LED lights.
5) Suitable brightness
Appropriate brightness. If the LED display screen is not bright enough, it will not be visible during the day and the meaning of installing the display screen will be lost; if it is too bright, it will affect driving.
6) LED brightness attenuation
LED attenuation characteristics: LED screen brightness is attenuated, with a 10-70% attenuation rate 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 display content clearly.
7) Others include appearance dimensions, etc.
