Claim 7:
8. A method of controlling a display device, the method comprising:
controlling on or off of a plurality of switching devices based on a magnitude of an input voltage input to a transformer;
controlling at least one switching device to always turn off so that the transformer operates as a half bridge LLC converter in response to the magnitude of the input voltage exceeding a predetermined value;
determining a method for a modulation control of an output voltage of the transformer as one of changing modulation width of the plurality of switching devices or changing modulation frequency of the plurality of switching devices based on the magnitude of the input voltage; and
based on the determined method for the modulation control, performing the modulation control of an output voltage of the transformer so that the output voltage of the transformer follows a predetermined reference voltage.
