Electronic paper label apparatus

Abstract

An electronic paper label apparatus (10) includes a dual interface memory unit (102), a microcontroller unit (104) electrically connected to the dual interface memory unit (102), an electronic paper driver unit (106) electrically connected to the microcontroller unit (104), and an electronic paper unit (108) electrically connected to the electronic paper driver unit (106). The dual interface memory unit (102) includes a communication bus interface subunit (110) electrically connected to the microcontroller unit (104), a memory subunit (112) electrically connected to the communication bus interface subunit (110), a radio frequency interface subunit (114) electrically connected to the memory subunit (112), and a voltage regulator subunit (116) electrically connected to the radio frequency interface subunit (114), the microcontroller unit (104), and the electronic paper driver unit (106). The efficiency of the present invention is that the electronic paper label does not need the power of the batteries. The electronic paper label acquires power from the radio frequency identification signals, or from the near field communication signals.
