Abstract:

There are some disadvantages about traditional epaper display device，such as huge power consumption,inconvenience content update.So,a terminal passive epaper display device which based on LPC824 ,combined NFC and wireless charging technology and configured APP is designed to enhance the convenience,reduce the volume and power consumption. It can refresh the information of the epaper when the NFC Mobile phone gets close to the disply device,and retain the information for a long time while the phone gets away from the device , all of it no need power supply. Finally,test for the design is done and the experimental results proved the rationality of the scheme, confirmed the theoretical research significance and practicability of the design.

Key words: NFC；e paper；wireless coupling；LPC824
