Claim 17:
18. A display system comprising:
a display device;
a processor configured to control the display device; and
a power voltage supply circuit,
wherein the power voltage supply circuit includes:
a voltage converter configured to convert an input voltage and output a first power voltage to a branch node;
a first output node connected to the branch node and configured to output the first power voltage;
a second output node connected to the branch node; and
a charge pump connected between the branch node and the second output node and configured to transform the first power voltage with an adjustable gain value,
wherein a transformed first power voltage is output as a second power voltage through the second output node, and
wherein the first and second power voltages are provided to the display device through the first and second output nodes, respectively.
