Abstract
A DC-DC converter includes a first power source generator, the first power source generator including an input port and a first output port, the first power source generator being configured to receive an input power source to the input port, and being configured to generate a first power source, the first power source being output to the first output port, and a selecting unit, the selecting unit being configured to selectively transmit, to the first power source generator, one of: a feedback voltage, the feedback voltage being input from an external feedback wiring line via a feedback terminal, and a voltage of the first output port.
Claims20
A DC-DC converter, comprising:
- a power source generator including an input port and an output port, the power source generator to receive an input power source voltage from the input port, and to generate a power source voltage, the power source voltage being a positive voltage or a negative voltage to be output to the output port;
- and
- a selector to selectively transmit to the power source generator:
- a feedback voltage input from an external feedback wiring line via a feedback terminal, or
- a voltage of the output port.
An organic light emitting display, comprising:
- a display panel including a plurality of pixels, the pixels each being coupled to a scan line, a data line, and a power source line;
- and
- a DC-DC converter provided outside the display panel, the DC-DC converter to generate a power source and to supply the generated power source to each of the pixels through the power source line, the DC-DC converter including:
- a power source generator, the power source generator including an input port and an output port, the power source generator to receive an input power source to the input port, and to generate the power source voltage, the power source voltage being a positive voltage or a negative voltage to be output to the output port;
- and
- a selector to selectively transmit to the power source generator:
- a feedback voltage, the feedback voltage being input from an external feedback wiring line via a feedback terminal, and
- a voltage of the output port.
