Application of wireless LED display screen
Wireless LED display screen is a kind of brand-new information media information, once launched, it is widely accepted social group, the "flow" display and the characteristics of the network information release more advertising, become a kind of new advertising media.
According to the use of technology can be divided into the WLAN, GRPS (WCDMA), and other wireless communications:
1.Such as buildings, plant, streets, inconvenient or wiring
Such LED displays is area of medium full-color displays, more need to release information in real time. For such display, if the condition allows, the wireless LED display we recommend using WLAN communication methods in the first place. This is because, compared with the GRPS communication way, WLAN need only wireless network card can be realized. Late cost is very low, and requires no additional traffic fees.
2.Multiple in different location of the LED screen, need to unified management, centralized, and the wiring is not convenient:
This application found in schools, institutions, government departments, streets, etc., such as Shanghai sea the LED display on both sides of the street, each separated by about 10 meters have an LED display screen, the whole street several hundred yuan display, unified management.This kind of display because of far distance control center, this kind of LED billboard for using the GPRS wireless communication way.
The most typical application is vehicle display, especially the LED display on the taxi.Due to the LED display has been with the moving of the car and mobile, combined with the need to focus on management, wiring is unlikely.This kind of LED display need to adopt the GPRS wireless communication way.
Wireless WLAN LED display by using more for synchronous control system, the mode of GPRS is given priority to with asynchronous control system.
