A Solution of LED Large Screen Display Based on Wireless Communication

Abstract

Display information of some LED large screen displays such as mobile offline LED display, bus LED display, can not be transmitted easily or directly from control PC for the limitation, inconvenient installation of communication wire. The paper gives methods for the combination of LED large screen display control technology and wireless data transmission technology, laying emphasis on the realization method of wireless display data transmission, presenting dual RAM buffer structure and ping-pong control circuit to realize the storage of display data, presenting display data scanning interface to enhance the driver capability of scanning signals. The solution makes display information configuration flexible and reduce the inconvenience due to the reasons such as inconvenient installation of communication wire.
