LED electronic screen after years of development, vehicle LED electronic screen is installed on the car, using special power supply, receiving and outputting data to lattice LED module board through control card, and displaying text, picture, animation and video by controlling dot matrix on and off. As a more novel advertising information dissemination media, vehicle LED display screen can store a large number of text information. Through the built-in microprocessor to control the display mode of text and font, the display function of timing display can be realized, and the mobile communication can be carried out everywhere.
Classification of vehicle LED electronic screen
1. Classification by carrier
(1) Taxi LED electronic screen: the top screen / rear window screen of taxi, which is used to scroll and play text. Most of them are single and double color, and most of them display some text information and scroll advertising information. The roof panel can be customized with empty car license plate in front of the ceiling lamp, the effect is better.
(2) Bus LED electronic circuit board: it is mainly used to display the information of up and down, brake, left turn, right turn, etc. on the right side of the bus, or display the arrival prompt information in the bus, and most of them are single and double colors.
(3) The main function of the car is to display the public service information on the car roof and on the road.
2. Classification by advertising release method
(1) U-disk type: when the number of cars is small or the content of characters is not often changed, such as the display screen of bus platform. When changing the screen display content, the content that needs to be changed is saved in the U disk first, and then inserted into the USB interface of the screen.
(2) GPRS type: when the number of cars reaches a certain number, it will be very troublesome to change the content one by one. Or it will be very troublesome to change the content of the characters. So, if you use GPRS wireless LED control card directly, the computer remote control will bring more convenience to the customers and get twice the result with half the effort.
(3) GPS type: GPS type and GPRS type are the same in advertising. However, due to the other functions of GPS, it brings a lot of convenience to taxi company management. In addition, because GPS can take satellite time at any time, GPS LED display screen is much better than GPRS type screen in advertising synchronization.
