LED display board, with the rapid development of
LED display and a set of independent onboard LED display system, compared with the conventional Door display, LED display moving stationary, its stability, anti-interference, anti- Vibration, dust and other aspects are better.
1. High brightness, adaptability, and play all day. With ultra-high brightness LEDs, the sun is still visible at a distance. From south to north, from east to west, the cold and hot dry and wet environment is adapted.
2. Easy to operate and easy to use. Whether it's using a computer or a mobile phone, changing the information and playing the video is very convenient.
3. Mobile media, the spread is stronger, the coverage is wider, and the effect is better. Compared to other LED displays, the car LEDs are always in motion. Advertising information can be played at any time along with the car, which is more powerful than a fixed advertising platform and covers a larger area.
4. Modular design, reliable performance and easy maintenance. Display, control, power supply separately designed, self-contained module, more stable and easy to maintain.
The way LED displays are classified in different ways is also different.
1. Classified by advertising method
1. Serial port type/U disk type: When the number of cars is small, or the contents of the characters are not changed frequently, such as the bus station display. When changing the content of the screen, you need to use the serial cable to connect to the computer to change, or save the content to be saved into the USB flash drive and then plug it into the USB interface of the screen. (However, there can be no other content in the U disk)
2, GPRS type: When the car reaches a certain number, it will be very troublesome to change the content of the word one by one. Or it is very troublesome to change the content of the words frequently. Therefore, directly using the remote control of the computer 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, but because of the other functions of GPS, it brings a lot of convenience to the management of taxi companies. In addition, because GPS will take satellite time at any time, GPS-type LED display is much better than GPRS-type screen in terms of advertising synchronization. The GPS-type LED car display can be accurate to the second in terms of ad synchronization.
2. Sort by color
1. Monochrome: generally has red, yellow, blue, green and white light colors, mainly used for taxi top display advertising, and street sign information on the front and rear of the bus;
2. Two-color: one screen has two colors to display, mainly used for the function screen of the bus; full color: also known as color screen, mainly used for other types of car body display full-color advertising information, most of the area is relative to single color The car screen is large, the production cost is high, but the effect of playing the advertisement is better.
3. Classification by carrier
1. Taxi LED screen: Taxi top screen / rear window screen, LED strip screen used to scroll text, mostly single and double color, most of them display some text information to scroll advertising information.
2. Truck LED large screen: It is mainly converted into LED display by the body of large truck, and the full-color picture is highlighted in high-definition, and the high-protection LED display can be waterproof and anti-sunlight on the periphery of the car body. High-definition full-color display of advertising information, richer display to achieve a more intuitive to leave a deeper advertising impression to passers-by.
3. Bus LED display: It is mainly used to display street signs on buses, and it is mostly in single and double colors.
