Abstract
Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device includes an amplifier to perform amplification based on an input differential signal, an output driver to output an audio output signal based on an output signal from the amplifier, a reference voltage output device to output a reference voltage in response to power ON, a pre-output driver configured to pre-compensate for an offset voltage and output a compensation signal, based on an output signal from the amplifier after the power ON, and a first switching device disposed between an output terminal of the output driver and an output terminal of the pre-output driver, wherein the output driver operates after the first switching device is turned on in response to the power ON. Accordingly, pop noise and harmonic distortion in case in which power is turned on may be reduced.
