Abstract
Provided are an array substrate and a display panel. The array substrate includes a scanning circuit including shift register units, each of which includes a forward and reverse scanning module including a first to fourth input units. The first to fourth input units includes a first to fourth transistors, respectively. First electrodes of the first and fourth transistors are connected to a first power supply terminal continuously providing a low-level signal. First electrodes of the second and third transistors are connected to a second power supply terminal continuously providing a high-level signal. Second electrodes of the first to fourth transistors are connected to a pull-up node. The first and fourth transistors pull down a potential of the pull-up node. The second and third transistors pull up the potential. During switching between forward scanning and reverse scanning, the roles of the first to fourth transistors do not change.
