    Abstract: Provided are a display panel including multiple scan lines located in the display region and gate drive unit groups located in a non-display region. The gate drive unit groups include at least one first gate drive unit group and at least one second gate drive unit group. The first gate drive unit group includes multiple cascaded first gate drive units. The second gate drive unit group includes multiple cascaded second gate drive units. The first gate drive units and the second gate drive units are connected to different scan lines. A first period during which a first gate drive unit at the first stage transmits an effective level signal to a scan line and a second period during which a second gate drive unit at the first stage transmits an effective level signal to a scan line overlap, overlap duration is t, and t>0.

    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.
