CHARGE PUMP FOR PRODUCING DISPLAY DRIVER OUTPUT |
摘要 |
<p>This disclosure provides systems, methods and apparatus for driving a display array with a waveform having a plurality of voltage levels, wherein a first subset of the plurality of voltages is different from a second subset of the plurality of voltages by a defined amount. In one aspect, a display driver circuit comprises a power supply configured to generate the first subset of said plurality of voltages, and a charge pump having the first subset of the plurality of voltages as inputs and the second subset of the plurality of voltages as outputs. The charge pump may not include a switch between each output voltage and a corresponding capacitor.</p> |
