Abstract
A portable electronic device includes a main body and a cover rotatably mounted to the main body. The main body includes a central processing unit (CPU), a sensor, a first display, and a second display. The sensor, the first display, and the second display are connected to the CPU. The cover includes a third display connected to the CPU. The CPU detects the position of the cover relative to the main body using the sensor, switches the first display on when the cover is positioned at a first state, and switches the second display and the third display on when the cover is positioned at a second state.
