Abstract
The present disclosure provides a charging control method for a display panel, including the following steps: controlling a source charging voltage waveform provided by a data line when touch and display on the display panel are simultaneously performed to enable the source charging voltage waveform to consistently vary with a voltage waveform of a common electrode of the display panel. The present disclosure further provides a display panel and a liquid crystal display.
