Car LED display function and seven characteristics

The vehicle-mounted LED display uses led technology, GSM/GPRS technology, low-temperature technology, anti-static technology, anti-interference technology, vehicle electronic technology, etc. to display information products on mobile cars. Because it is based on mobile buses as a medium, it can be widely circulated in many places, bringing great advertising promotion effects, and is widely accepted, which is different from ordinary LED display screens installed in fixed places. The reason lies in the car and advertising.

Features of car led display:

1) High stability and reliability

The car is always on the move, and every time the brake starts to turn, there will be some weak pulling power. Therefore, the on-board LED display requires high stability and reliability of electronic products.

2) Stable power system support

The power supply on the car is powered by a battery. Similarly, when the car starts, brakes, and stops, the power supply voltage will be unstable for a short time. 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 the power supply and display components to work at a wide temperature.

4) Good anti-static measures

Cars are prone to static electricity during operation, especially in autumn, where the high voltage of static electricity can reach thousands of volts. Without good anti-static measures, electrical sparks can easily damage ICs and LED lights.

5) Appropriate brightness

Appropriate brightness. If the brightness of the LED display is not enough, it will not be visible during the day, which loses the meaning of installing the display; if it is too bright, it will affect the driving.

6) LED brightness attenuation

This is a common feature of LED products. LED attenuation characteristics, LED brightness is attenuated, there is a 10-70% attenuation rate in a year, the brightness is reduced by half in half a year with poor quality, making it impossible to see the display content.

7) Good promotion

It can be said that public buses and other means of transportation can be said to be everywhere in the city, so its advertising effect can also affect the entire city, thus bringing great publicity effects for products and services.
