Analysis of The Functional Characteristics of The Car LED Display

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. It is different from ordinary LED display screens installed in fixed places. The reason lies in the car and advertising.

Analysis of the functional characteristics of the car LED display

Features of car LED display:

1) High stability and reliability

Cars are always on the move, which requires high stability and reliability of electronic products.

2) Stable power system support

The power supply on the car is powered by a battery. The car will generate a very high pulse voltage when starting, braking, and stopping. If the power 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 generate static electricity during operation, especially in autumn, where the high voltage of static electricity can reach thousands of volts. Without good anti-static measures, it is easy to damage IC 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, and it will lose the meaning of installing the display; if it is too bright, it will affect the driving.

6) LED brightness attenuation

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) There are other appearance dimensions, etc.
