  • Patent number: 7982726
    Abstract: A display device and a method of checking signals input to a display device. The display device includes a signal identifying unit, a signal checking unit, and a signal changing unit. The signal identifying unit receives an input signal and identifies the type of input signal that is received. The signal checking unit checks whether the identified input signal is abnormal. The signal changing unit switches from the checked input signal to a next input signal to be checked so that the signal checking unit can check whether the next input signal is abnormal, after the signal checking unit checks whether the input signal is abnormal. Accordingly, when a display device goes to an abnormal mode, one of input signals can be checked in the display device to automatically change to another signal according to the order of checking the signals, the time required to check the signals, and the number of times the signals are checked without manipulating an additional key.
