Abstract
An electronic paper display apparatus comprises an electronic paper display unit, a control unit electrically connected to the electronic paper display unit and including a power-level detection circuit, a storage unit at least storing an identification/alert information and electrically connected to the control unit, a wireless communication module and a power unit. The wireless communication module is electrically connected to the control unit and includes a satellite positioning receiving unit, which receives a current satellite positioning signal of the electronic paper display apparatus. The power unit is at least electrically connected to the power-level detection circuit of the control unit. When a power of the power unit is greater than or equal to a first power threshold and less than or equal to a second power threshold, the control unit loads the identification/alert information and a satellite positioning information in the storage unit into the electronic paper display unit.
