The application of LED displays in traffic has made vehicle-mounted LED displays widely popular. Vehicle-mounted displays appearing in streets and alleys have also added a lot of color to our daily life in traffic. What kind of characteristics? Let's make a simple analysis on the LED brightness, power supply, protection measures and other technologies of the car display screen.

1. LED brightness attenuation:

  LED attenuation characteristics, LED brightness is attenuating, there is a 10-70% attenuation rate in one year, and the brightness of the poor quality is reduced by half in half a year, making it impossible to see the display content.

2. Stable power system support:

  The power supply on the car is powered by a battery. The car will generate a high pulse voltage when it starts, brakes, and stops. If the power supply system is not good, the LED display will be burned.

3. High stability and reliability:

  Cars are always moving, and the stability and reliability of electronic products are very demanding.

Fourth, good anti-static measures:

  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.

 Fifth, the brightness is appropriate:

 Appropriate brightness; if the LED display is not bright enough, it will be invisible during the day and lose the meaning of installing the display; if it is too bright, it will affect the driving.

 6. Ultra-large-scale transmission:

 Can provide anywhere with telecom operator network coverage.

 Common wireless car LED display operation methods are as follows:

 1. Send information to the wireless SMS screen by directly editing the mobile phone SMS. This method is suitable for customers who have a small number of screens and can send information anytime, anywhere.

 2. Send information to the wireless short message display screen through the Internet, which is characterized by: editing information is convenient and fast, and there is no need to purchase a short message sender. It is suitable for customers who have a large number of screens and can easily access the Internet.

 3. Use the computer to send information to the wireless short message display screen through the mobile phone transmitter. Its characteristics are; editing information is convenient and fast without Internet access. It is suitable for customers who have a large number of screens and cannot access the Internet.

 The built-in GPRS module is equivalent to an Internet user, and will be dynamically assigned an IP address every time it is powered on. In this way, any computer connected to the Internet can use the wireless LED display to send software to send information to the LED display. Basic requirements:

 1. User computer terminals are required to access the Internet through wireless or wired means.

 Second, the user's computer interruption needs to install the wireless LED display sending software.

 3. If the user establishes a service network by himself, he needs to apply for a fixed IP address and ensure that the service is online in real time.

 Fourth, transmit information through GPRS network, low cost, good real-time performance, suitable for the transmission of large-capacity text information or image information content.

 5. The wireless paging screen has a built-in paging receiver, which can receive and display information anytime and anywhere within the coverage of the paging station signal. The information can be transmitted by dialing and paging or using the wireless information release system, and the information transmission method is simple and timely.
