Abstract
An electronic paper apparatus including a communication module and a control module is provided. The communication module receives an electrical signal and generates a power voltage according to the electric signal. The communication module wakes up a controller during a first period of a work period by using the power voltage. The control module is electrically connected to the communication module, and includes the controller and an electronic paper display. The control module establishes a communication connection with the communication module during a second period of the work period. The power circuit module generates a driving voltage according to the power voltage to drive the electronic paper display to display image information according to the driving voltage during a display period. The first period and the second period are two continuous time intervals forming the work period. Furthermore, a driving method of the electronic paper apparatus is also provided.
