Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a display device, which includes a plurality of light receiving units and can be easily installed in a state of the optimal installation. SOLUTION: The display device includes a plurality of light receiving units 20a-20d for receiving a remote control signal transmitted from a remote control unit and a CPU (control portion) 10 for decoding an output signal output from the light receiving units and controlling the operation of the display device according to the decoded results. The CPU 10 detects mixing of noise into the output signal output from light receiving units 20a-20d when the light receiving units 20a-20d are in a state not receiving the remote control signal, and distinguishes the reception state under noise for the light receiving units 20a-20d, based on the detected results. Then, the distinguished results are displayed on a display screen of the display device. COPYRIGHT: (C)2010,JPO&INPIT |
