Abstract
Aspects of the invention provide an electronic paper display system that can include an electronic paper and the writing device. The writing device transmits power and baseband signals by using an electromagnetic coupling between a coil of the writing device and a coil of the electronic paper. The baseband signals, which are encoded by the writing device, are decoded by a decoder of the electronic paper and fed to the control circuit to illustrate images on a bi-stable display unit. The electronic paper has a power storage that temporarily stores power transmitted by using electromagnetic coupling for absorbing fluctuation of power in both transmission and consumption. The asynchronous design of this invention brings both robustness and low-power consumption.
