IMAGE DISPLAY APPARATUS AND METHOD FOR CONTROLLING SAME
First Claim
1. An image display apparatus receiving an input signal for selecting a channel from an external input device, the apparatus comprising:
- a tuner capable of selecting a broadcast signal corresponding to a specific channel based on the input signal, and switching the selected broadcast signal into an image signal;
a display unit capable of outputting an image associated with the specific channel using the switched image signal;
a power supply unit provided with a battery, and capable of charging the battery while electric energy is received from the exterior, the power supply unit supplying power to the display unit using the externally-received electric energy;
a power failure sensing unit capable of sensing whether or not power failure that the externally-supplied electric energy is cut off occurs; and
a controller capable of supplying power to the display unit using the battery when power failure is sensed by the power failure sensing unit, and adjusting brightness of at least one area of the display unit based on a residual capacity of the battery.

Abstract
The present disclosure relates to an image display apparatus including a battery and a method for controlling the same, and the image display apparatus, which receives an input signal for channel selection from an external input device, comprising: an antenna; a tuner for selecting a broadcast signal corresponding to a specific channel, among signals received through the antenna, on the basis of the input signal and converting the selected broadcast signal into an image signal; a display unit for outputting an image associated with the specific channel by using the converted image signal; a power supply unit which includes a battery, charges the battery while electric energy from the outside is received and supplies power to the display unit using the electric energy received from the outside; a power failure detection unit for detecting whether power failure corresponding to a cut off of the electric energy supplied from the outside occurs; and a control unit for supplying power to the display unit using the battery when the power failure detection unit detects power failure and controlling brightness of at least one area of the display unit on the basis of residual capacity of the battery.

17. A method for controlling an image display apparatus receiving an input signal for selecting a channel from an external input device, the method comprising:
-
selecting a broadcast signal corresponding to a specific channel, on the basis of the input signal, and outputting an image associated with the specific channel on the display unit using the selected broadcast signal; charging a battery while externally-supplied electric energy is received, and supplying power to the display unit using the externally-supplied electric energy; supplying power to the display unit using the battery when power failure occurs during the output of the image; and adjusting brightness of at least one area of the display unit based on a residual capacity of the battery. - View Dependent Claims (18, 19, 20)
