Abstract
The image display apparatus according to an embodiment of the present disclosure includes: a display; a signal processing device; and a power supply to supply a display driving voltage to the display, wherein the power supply includes a converter including switching elements and to convert a level of an input DC voltage and output the display driving voltage, wherein in response to a load at an output terminal of the converter, the converter is configured to operate in a first mode, in which the switching elements perform a continuous switching operation at a first frequency, and in a second mode in which the switching elements perform the continuous switching operation and then stop the switching operation for a predetermined period or perform the switching operation at a second frequency lower than the first frequency. Accordingly, it is possible to reduce increase of output voltage under low-load or no-load conditions.
