Disclosed are an electronic device and an operation method thereof according to various embodiment, the method comprising: reproducing first content on a first display unit having variable transparency; detecting an object in response to the first display unit; controlling transparency in at least a partial area of the first display unit on the basis of the object; and reproducing second content on a second display unit, disposed to be spaced from the first display unit.

Electronic device and operation method thereof

An apparatus for and a method of controlling battery discharge. A number of battery switching operations is minimized by detecting a remaining voltage capacity of each of a plurality of batteries supplying a battery-powered electronic device with power. The remaining voltage capacities of an internal battery and an external battery are detected and corresponding flags are set for the internal and external batteries according to predetermined conditions. A discharge status of at least one of the internal battery and the external battery is controlled by referring to the flags and a remaining voltage capacity of each of the internal battery and the external battery.

Apparatus and method for controlling battery discharge between internal battery and external battery

A computing device allows selective output of audio signals within a frequency band. The computing device has a main system having an audio signal generator generating audio signals, a main audio outputting unit attached to the main system and outputting the generated audio signals, an auxiliary system connected to the main system and receiving the audio signals generated by the audio signal generating unit, and an auxiliary audio outputting unit attached to the auxiliary system and outputting the audio signals received in the auxiliary system A switching unit controls the audio signals to pass through a plurality of selectable filters filtering the audio signals within respective frequency bands and to supply the selected filtered audio signals to the main audio outputting unit, and to the auxiliary audio outputting unit, depending upon whether the auxiliary system is connected to the main system.
