Abstract
An image display apparatus is disclosed. The image display apparatus includes a signal processing device having a transceiver that includes a current sweep circuit configured to output a plurality of sweep currents, a current selector connected to the current sweep circuit and configured to select a predetermined current from the plurality of sweep currents based on comparison with a reference voltage, and a comparator configured to compare a voltage output from the current selector with the reference voltage. Accordingly, a constant output voltage level can be obtained.
