US 2019/0057626 A1 · ELECTRONIC TAG AND DRIVING METHOD THEREOF

Abstract

An electronic tag including an electronic paper display, a driving circuit, and an energy harvesting device is provided. The electronic paper display is configured to display tag information. The driving circuit is coupled to the electronic paper display and includes a voltage detecting circuit. The energy harvesting device is coupled to the driving circuit and configured to generate a first power signal. The voltage detecting circuit is configured to receive the first power signal. When a voltage value of the first power signal is higher than a threshold voltage value, the voltage detecting circuit outputs the first output power signal so that the driving circuit enables the electronic paper display by the first output power signal. In addition, a driving method of the above electronic tag is also provided.
