Abstract
A driving method for a display panel, a pixel driving circuit, and a display panel are provided. An image to be displayed is divided into multiple consecutive display stages, a first control signal is provided for 1st to (N−1)-th subframes, a second control signal is provided for the N-th subframe, and different pixel data structures are obtained for different display stages. A first control signal is a pulse width modulation (PWM) signal, and a second control signal is a pulse amplitude modulation (PAM) signal. Accordingly, the display performance is effectively enhanced.
