Abstract
An electronic device () according to one embodiment may comprise: a display (); a first converter circuit () which includes a non-inverting buckbooster () and a charge pump () and is configured to supply a negative first bias voltage to the display (); and a control circuit (). The control circuit (), according to one embodiment, can be configured to check a target first bias voltage to be supplied to the display (). The control circuit (), according to one embodiment, can be configured to output a first voltage corresponding to half the absolute value of the target first bias voltage to the charge pump () by using the non-inverting buckbooster (). The control circuit (), according to one embodiment, can be configured to generate a second voltage by inverting the sign of the first voltage and converting the magnitude of the first voltage by a factor of two through the charge pump (). The control circuit (), according to one embodiment, can be configured to supply the second voltage to the display () as the first bias voltage.
