LED car screen is the use of led technology, anti-static technology, low temperature technology, vehicle electronic technology, anti-jamming technology, etc. to display information products on mobile vehicles. It is different from the ordinary LED display installed in a fixed place. The reason is that the car LED display is installed on the car, the car moves frequently, etc., and there are certain requirements for the installation. So, what are the common characteristics of car LED display?
1. Cars are prone to generate static electricity during operation. Especially in autumn, the high voltage of static electricity can reach thousands of volts. If there is no good anti-static measures, it is easy to damage IC and LED lights.
2. The power supply on the car is powered by a battery. When the car starts, brakes, and stops, a high pulse voltage will be generated. If the power supply system is not good, the display screen will be burned.
3. LED attenuation characteristics, LED brightness is attenuated, with a 10-70% attenuation rate in one year, and the brightness of poor quality is reduced by half in half a year, making it impossible to see the display content.
4. 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 in a wide temperature range.
5. Appropriate brightness. If the brightness of the LED display is not enough, it will not be visible during the day, and the meaning of installing the display will be lost; if it is too bright, it will affect the driving.
6. Cars are always moving, which requires high stability and reliability of electronic products.
7. The common features of car LED display are the appearance size and so on.
