Abstract: A portable electronic device with large display screen-to-body includes a housing, a first display, a circuit board, and an optical module. The first display is a transparent display. The optical module is electrically connected to the circuit board and positioned below the first display. The first display, the optical module, and the circuit board are received in the housing, the optical module is configured to receive external light passing through the first display even as the first display is displaying images. Operating methods for the portable electronic device in various modes are also provided.

Abstract: An electronic device includes a housing. The housing defines a slot and a groove communicating with the slot. The housing is divided into at least a first radiating portion and a second radiating portion by the slot and the groove. The first radiating portion is spaced apart from the second radiating portion. The first radiating portion and the second radiating portion cooperatively serve as an antenna structure of the electronic device to receive and/or transmit wireless signals. The electronic device further performs a predetermined function through the groove.

Abstract: An antenna system in a wireless communication device includes a first antenna, a second antenna, a baseband microchip, a signal sensing unit, a logical circuit, and a switch unit. The first antenna receives and transmits wireless signals; the second antenna transmits wireless signals. The baseband microchip processes the wireless signals and provides a voltage logic signal. The logical circuit logically processes the voltage logic signal and the command signal to generate different switch signals, and the switch unit is controlled by the switch signals from the logical circuit to connect to the first antenna or to the second antenna to transmit the wireless signals.
