After years of development, LED electronic screens have become popular for the dissemination of mobile information,
The on-board LED electronic screen is installed on the vehicle and powered by a special power supply. It receives and outputs data to the dot matrix LED unit board through the control card, and displays text, pictures, animation and video by controlling the lighting of the dot matrix. As a more novel advertising information communication media, vehicle LED display can store a large amount of text information, control the display mode of text and font through built-in microprocessor, realize the timing display function, and move and spread everywhere.
Classification of vehicle LED electronic screen
1. Classification by carrier
(1) Taxi LED electronic screen: taxi top screen / rear window screen, which is used to scroll the LED bar screen for playing text. Most of them are single and double colors, mostly displaying some text information and rolling advertising information. The roof screen can be customized with a roof lamp with empty vehicle passenger brand in front, which has better effect.
(2) Bus LED electronic circuit board: it is mainly used in front and back of the bus. The right side displays information such as up and down, braking, left turn, right turn, or arrival prompt information in the bus, mostly in single and double colors.
(3) Led on-board electronic screen of police vehicle and official vehicle: it is mainly installed on the roof of official vehicle to display public welfare information such as warning information, road condition prompt and performing official duties, and can integrate the function of flash lamp.
2. Classified by advertising method
(1) USB flash disk type: when the number of vehicles is small or the word content is not often changed, such as the bus stop display screen. When changing the content displayed on the screen, the content to be changed can be saved in the USB flash disk first, and then inserted into the USB interface of the screen.
(2) GPRS type: it will be troublesome to change the word content one by one when the number of cars reaches a certain number. Or it will be troublesome to change the word content often. Therefore, using GPRS wireless LED control card directly and computer remote control will bring more convenience to our customers and get twice the result with half the effort.
(3) GPS type: GPS type and GPRS type are the same in advertising. However, other functions of GPS bring a lot of convenience to the management of taxi companies. In addition, because GPS will take the satellite time at any time, the advertising synchronization of GPS LED display screen is much better than GPRS word walking screen.
