摘要： A display device includes a display panel displaying an image. A light source unit provides light to the display panel. A cover member covers a portion of an upper surface of the display panel and a side surface of the display panel. The cover member exposes a display area of the display panel. A thermoelectric device is disposed between the cover member and the light source unit. The thermoelectric device contacts the cover member, and the thermoelectric device generates an electromotive force due to a difference in temperature between the light source unit and the cover member.

摘要： A mobile communication device includes: a first sound transceiver including a first lower electrode, a first upper electrode, and a first vibration plate between the first lower electrode and the first upper electrode; a second sound transceiver including a second lower electrode, a second upper electrode, and a second vibration plate between the second lower electrode and the second upper electrode; a position sensor configured to perform a detection of a relative positional relationship between the first and second sound transceivers; and a controller configured to apply a sound signal to one of the first and second sound transceivers and detect a sound signal from the other one thereof, based on the detection result provided from the position sensor.
