Vehicle screens are mobile information carriers based on LED technology, mainly used in transportation, commerce and public services. They transmit news, advertisements and other information in real time through text and images, and are commonly found in taxi roof lights, bus interior and exterior screens and other scenarios. According to the display type, they are divided into monochrome, dual-color and full-color, and the installation location covers multiple areas such as the roof and windows of the vehicle. They support GPRS/3G wireless transmission and remote control.
Vehicle screen hardware includes LED unit boards, control cards and dedicated power supplies. It has shockproof and heat dissipation design, and realizes cluster broadcast control and precise electronic fence projection through the cloud platform . The technological evolution shows the trend of large screen and flexibility, such as the BOE 45-inch 8K smart screen and the Visionox 14.2-inch sliding screen. At the same time, it integrates AR-HUD, transparent display and other technologies, turning the windshield into an information interface. In the smart cockpit, vehicle screens undertake vehicle control, environmental perception and entertainment interaction functions. Tesla's 17-inch vertical screen and Audi's three-screen quad-core system and other cases promote the digital development of human-computer interaction.
