Four aspects of the car LED display classification

The car LED display is a set of display system that is independent with the rapid development of the LED display. Compared with the ordinary door screen and the fixed non-moving LED display, it is stable, anti-interference and anti-vibration. The requirements for dust prevention and other aspects are higher. The way LED displays are classified in different ways is also different. The following is a classification of its four aspects:

First, according to the spacing of the beads

1, P6: lamp bead spacing is 6mm, generally used in taxi advertising screen, display delicate, visible distance 10-50m.

2. P7.62: The lateral spacing is 6mm, the longitudinal spacing is 7.62mm, and the visible distance is 30-80m.

3. P10: The distance between the lamp beads is 10mm, which is applied to the bus screen.

Second, by color

1. Monochrome: Generally, there are red, yellow, blue, green and white light colors, mainly used for taxi top display advertisements, and street sign information on the front and rear sides 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.

Third, classified by carrier

1. Taxi LED screen: Taxi top screen/rear window screen, LED strip screen for scrolling 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 LED display with high protection level such as waterproof and anti-sunlight can be done 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: mainly used to display street signs on the bus, and mostly in single and double colors.

Fourth, 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.
