PROBLEM TO BE SOLVED: To provide an electronic device which can easily reduce power consumption of a display unit.SOLUTION: An electronic device comprises: a display unit 10; a display control unit 12 which displays an image on the display unit on the basis of image signals input from the outside; a first power supply unit 20 which converts alternating current power into first power at first voltage, and supplies the first power to the display unit; a breaking unit 24 which breaks the alternating current power supplied to the first power supply unit on the basis of the image signals; a second power supply unit 22 which converts the alternating current power into second power at second voltage, and supplies the second power to the display control unit and the breaking unit; and a selection unit 42 which selects one of a plurality of servers 50 and transmits image signals output by the selected server to the display control unit. At least one of the plurality of servers supplies third power to the selection unit, and when the third power becomes unstable, the second power supply unit supplies the second power to the selection unit. 【課題】簡単に表示部の消費電力を削減すること。【解決手段】表示部１０と、外部から入力された画像信号により前記表示部に画像を表示する表示制御部１２と、交流電力を第１電圧の第１電力に変換し前記表示部に供給する第１電源部２０と、前記画像信号に基づき、前記第１電源部に供給される前記交流電力を遮断する遮断部２４と、前記交流電力を第２電圧の第２電力に変換し前記表示制御部および前記遮断部に供給する第２電源部２２と、複数のサーバ５２の一つを選択し、前記選択されたサーバが出力する画像信号を前記表示制御部に送信する選択部４０と、を具備し、前記複数のサーバの少なくとも一つが前記選択部に第３電力を供給し、前記第３電力が不安定となった場合、前記第２電源部は前記第２電力を前記選択部に供給する電子装置。【選択図】図８
