Abstract: A driving method and a driving circuit for a display panel, and a display device. In the driving method, a binding-point voltage is first detected and a voltage difference between the binding-point voltage and a common-electrode voltage is obtained through a calculation. In case that the voltage difference between the binding-point voltage and the common-electrode voltage is smaller than a preset voltage difference, an existence of a problem of bright and dark lines on the display panel is indicated, the data voltage waveform has a ramp-up, and a charging rate of a blue pixel or a green pixel is insufficient, in this case, the binding-point voltage, i.e., a charging voltage of the red pixel is boosted to reduce a charging loss during a ramp-up process, and to increase the charging rate, so that the bright and dark lines of the display panel can be improved, thereby improving the display effect.
