Open publisher page 0 citations

Abstract

Most of LED-screens only support single screen display and have difficulty in displaying large area.In allusion to problem above,a new system,under the control of core chip LPC2148 with the help of programmable logic device EPM240,was proposed to implement the network communication between industrial locale and PC by RS485.The experiment results indicate that this system can realize wide area display,refresh frequency can be more than 60Hz,and can display different multimedia information.
