Classification: CPC G | IPC G

Claim 18:
19. A display apparatus comprising:
a power management device configured to supply a plurality of input voltages;
a display panel configured to display image data; and
a display driving circuit comprising a power module configured to supply power for driving the display apparatus, based on at least one input voltage received from the power management device,
wherein the power module is further configured to:
receive a first input voltage from the power management device,
generate a first output current using the first input voltage,
generate a second output current by receiving a second input voltage from the power management device based on the first input voltage being lower than a first reference voltage,
based on the first input voltage being higher than the first reference voltage, supply power for driving the display apparatus, using the first output current without using the second output current, and
based on the first input voltage being lower than the first reference voltage, supply the power for driving the display apparatus, using the first output current and the second output current,
wherein, the power supplied using the first output current and the second output current is greater than the power supplied using the first output current without using the second output current.
