Abstract:
A power converting circuit of a display driver includes a positive voltage generator and a negative voltage generator. The positive voltage generator includes a first capacitive DC-DC converter and a first inductive DC-DC converter, and generates a positive source voltage by selectively using one of the first capacitive DC-DC converter, the first inductive DC-DC converter, or a first external power supply voltage. The negative voltage generator includes a second capacitive DC-DC converter and a second inductive DC-DC converter, and generates a negative source voltage by selectively using one of the second capacitive DC-DC converter, the second inductive DC-DC converter, or a second external power supply voltage.
