Abstract
A DC-DC converter includes a plurality of converters and a discharging circuit. The converters convert an input power voltage from an input terminal to a plurality of output power voltages for output to a plurality of output terminals. The discharging circuit is between the input terminal and the converters and discharges of voltages of the output terminals based on a discharging control signal.
Claims20
A DC-DC converter, comprising:
- a plurality of converters to convert an input power voltage from an input terminal to a plurality of output power voltages for output to a plurality of output terminals;
- and
- a discharging circuit between the input terminal and the converters, the discharging circuit to discharge voltages of the output terminals based on a discharging control signal.
A display device, comprising:
- a display panel including a plurality of pixels;
- a scan driver to provide a scan signal to the pixels;
- a data driver to provide a data signal to the pixels;
- and
- a DC-DC converter to generate a plurality of output power voltages to be provided to the pixels, wherein the DC-DC converter includes:
- a plurality of converters to convert an input power voltage from an input terminal to the output power voltages for output to a plurality of output terminals;
- and
- a discharging circuit between the input terminal and the converters, the discharging circuit to discharge voltages of the output terminals based on a discharging control signal.
5 more elements
A DC-DC converter, comprising:
- a plurality of converters to convert a first power voltage to a plurality of second power voltages for output to pixels of a display through output terminals;
- and
- a discharging circuit to discharge third voltages of the output terminals based on a discharging control signal, wherein the second power voltages are different from one another and wherein discharging control signal is generated when a power mode of the display switches from a first state to a second state.
