Display panel, display device, and drive method

A display penal, comprising a plurality of sub-pixel units arranged in an array and a gate drive circuit, wherein the array comprises N rows;

• each of the plurality of sub-pixel units comprises a light-emitting unit, a pixel drive circuit configured to drive the light-emitting unit to emit light, and a sensing circuit configured to sense the pixel drive circuit;
• the gate drive circuit comprises a plurality of cascaded shift register units and N+1 output terminals arranged in sequence, each of the plurality of cascaded shift register units is configured to output a gate scan signal for driving at least two rows of sub-pixel units in the N rows of the array to work;
• and
• pixel drive circuits of an (n)-th row of sub-pixel units are connected to an (n)-th output terminal of the gate drive circuit to receive the gate scan signal as a scan drive signal, and sensing circuits of the (n)-th row of sub-pixel units are connected to an (n+1)-th output terminal of the gate drive circuit to receive the gate scan signal as a sensing drive signal,
• wherein, 1≤n≤N, N is an integer greater than or equal to 2.
