Analysis of the characteristics of car LED display

The car-mounted LED display screen is a product that uses LED technology, GSM/GPRS technology, low temperature technology, anti-static technology, anti-interference technology, and car-mounted electronic technology to display information on mobile cars . It is different from ordinary LED displays installed in fixed places. The reason lies in car-mounted and advertising.

Features of car LED display:

1) High stability and reliability

Cars are always moving, which places high demands on the stability and reliability of electronic products.

2) Stable power system support

The car is powered by a battery. When the car starts, brakes, or stops, it will generate very high pulse voltages. If the power system is not good, the display will be burned out .

3) Wide operating temperature range

In the north, cars are usually placed outdoors, where the temperature can reach -40°C in winter and 60°C in summer, requiring the power supply and display components to operate in a wide temperature range.

4) Good anti-static measures

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

5) Brightness Appropriate

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.

7) Other factors include appearance and dimensions.
