Car LED electronic display screen is with the rapid development of LED display and independence of a display system, and the door of the ordinary head fixed not mobile LED display screen, compared to its stability and anti-jamming, shock, dust and other higher requirements. LED display according to different ways of classification method is also different. The following tells its classification from four aspects:
The classification, according to the lamp bead spacing
P6: lamp bead spacing is 6 mm, usually used in taxi advertising screen, display fine, visual distance is 10 to 50 m.
2. P7. 62: horizontal spacing is 6 mm, longitudinal spacing is 7. 62 mm, visual range 30-80 - m.
3. P10: lamp bead spacing is 10 mm and more likely to be applied to bus screens.
Second, according to the classification of color
1. The single color: red, yellow, blue, green white light color, generally have LED electronic display screen is mainly used for taxi top display advertising, and on both sides before and after the bus street information;
2. Double color: there are two kinds of a screen color display, LED display screen is mainly used for the function of the bus; Full-color: also called color screen, it is mainly used for other classes body shows full-color advertising message is given priority to, most larger screen area relative to the single and double color car, the production cost is high, but the advertising effect is better.
Third, classified by carrier
1. Taxi LED electronic display screen go words: taxi top screen/window screen, used to scroll text article LED screen, double color, mostly display some text scrolling advertising information.
2. The truck LED display screen: the main is a big truck body into a LED display, and with high bright display full-color images, do at the periphery of the car can waterproof, prevent sun high protection grade LED display. High-definition full-color display advertising information, richer display reaches more intuitive to the road of passers-by deeper advertising impression.
3. The bus LED display: it is mainly used for street signs displayed on the bus, and in the majority with single and double color.
Fourth, classified by way of advertising
1, serial type/U disk type: when the car number is less, or don't change often go word content, such as bus display platform. Changes within the screen go when word content need serial lines to connect the computer to change, LED electronic display screen, or to change the contents of the first deposit in U disk storage, and then insert the USB interface to the screen. Other contents (but can't have, U dish)
2, GPRS type: when the vehicle reaches a certain number, LED display a change a word content will be very troublesome. Or to change often go word content also will be very trouble, so, with the computer directly to the remote control will bring our customers more convenient, get twice the result with half the effort.
Type 2, GPS, GPS and GPRS advertised in this block is the same, but, as a result of the other function of the GPS to the taxi company management brings a lot of convenience. In addition, because the GPS will take satellite time at any time, so in advertising synchronicity, GPS LED display screen type is so much better than the GPRS go word. GPS type LED car LED electronic display in advertising synchronization can be accurate to seconds.This paper is derived from the network.
