Abstract: A display panel, a driving method thereof, and a display apparatus. The display panel includes a shift register circuit including shift units. The shift unit includes a first output circuit, a control circuit, and a first node. In a first mode, a display region includes a first sub-region refreshed with a first frequency and a second sub-region refreshed with a second frequency. The shift register circuit includes a first unit group and a second unit group. In some frames, the first and second unit groups output an active scanning level, and in some frames, the control circuit in a first shift unit supplies a non-enabling level to the first node at least after the first unit group outputs the active scanning level. The first shift unit is located in the second unit group and is adjacent to the first unit group.
