Power-saving driving circuit for display panel and power-saving driving method thereof

摘要

A power-saving driving circuit for a display panel is provided. The display panel includes a pixel array including a plurality of data lines. The data lines are grouped into a plurality of pixel regions according to a scan time. Each of the pixel regions has a plurality of pixels. The power-saving driving circuit includes at least one source driver. The source driver respectively supplies a driving voltage to the pixels on at least one of the data lines. The driving voltage supplied by the source driver to each of the pixel regions has a varying driving capability determined according to a pulse width and/or a rising slope of the driving voltage. The pulse width and/or the rising slope of the driving voltage is larger when the driving voltage is supplied for driving the pixels in the pixel region farther from the source driver.
