The car LED display uses LED technology , GSM/GPRS technology, low temperature technology, antistatic technology, anti-interference technology, and vehicle electronic technology to display information products on mobile vehicles. It is different from a normal LED display installed in a fixed location. The reason is car and advertising. Car LED display features: 1) High stability and reliability Cars are always moving, and they require high stability and reliability of electronic products. 2) Stable power system support The power supply on the car is powered by a battery. When the car starts, brakes, and stops, it will generate a high pulse voltage. If the power system is not good, the display will burn out. 3) Wide operating temperature range Cars in the North are generally placed outdoors. Winter temperatures may reach -40 ° C, summer temperatures may reach 60 ° C, which requires power and display components to work at wide temperatures. 4) Good anti-static measures Cars are prone to static electricity during operation, especially in the fall, electrostatic high voltage can reach thousands of volts, if there is no good anti-static measures, it is easy to damage IC and LED lights. 5) Suitable brightness 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) LED brightness attenuation LED attenuation characteristics, LED brightness is attenuated, 10-70% attenuation rate in a year, half-year brightness is reduced by half, resulting in invisible display content. 7) Others have appearance dimensions and the like.
