Abstract
Provided are a display panel with regional variable refresh rates and a driving method. The display panel includes: a region classification module for detecting in a display region of said panel row information corresponding to a static display region with an invariable picture and to a dynamic display region with a variable picture, and generating control signal groups of corresponding states; and a driving circuit for receiving a first control signal group corresponding to the static display region, so that drive voltages of related pixel rows of the static display region are output to the next row drive circuit, and an output signal of the drive circuit retains at a high level, or receiving a second control signal group corresponding to the dynamic display region, so that drive voltages of related pixel rows of the dynamic display region are output to both the next row drive circuit and the output signal of the drive circuit.
