Display panel and display device

A display device comprising a display panel comprising:

• a plurality of sub-pixels;
• a plurality of pixel circuits respectively connected to the plurality of sub-pixels;
• a driver circuit comprising a plurality of cascaded shift registers, the plurality of shift registers each being configured to output a primary scanning signal based on a clock signal;
• and
• a plurality of gating circuits respectively corresponding to the plurality of shift registers, the plurality of shift registers being connected to the plurality of pixel circuits via the plurality of gating circuits, and the plurality of gating circuits each being configured to provide a scanning signal to at least one of the plurality of pixel circuits;
• a display area comprising a plurality of display sub-areas, the plurality of display sub-areas comprising a first display sub-area and a second display sub-area, and a data refresh frequency of the first display sub-area being greater than a data refresh frequency of the second display sub-area,
• wherein the display panel has a first display mode and a second display mode,
• in the first display mode, data refresh is performed in each of the plurality of display sub-areas,
• in the second display sub-area, data refresh is performed in the first display sub-area, and data holding is performed in the second display sub-area, and
• in each of the first display mode and the second display mode, shift registers of the plurality of shift registers corresponding to the first display sub-area and shift registers of the plurality of shift registers corresponding to the second display sub-area are each configured to receive a clock signal with a first clock frequency.
