Display panel and display device

A display panel, comprising a plurality of sub-pixel units arranged in an array, wherein the array comprises N rows and 4M columns,

• sub-pixel units in each row are divided into a plurality of sub-pixel unit groups, and each sub-pixel unit group comprises a first sub-pixel unit, a second sub-pixel unit, a third sub-pixel unit and a fourth sub-pixel unit which are sequentially in four adjacent columns along a first direction;
• each sub-pixel unit of the plurality of sub-pixel units comprises a light emitting circuit, a pixel driving circuit for driving the light emitting circuit to emit light, and a sensing circuit for sensing the pixel driving circuit to realize external compensation;
• the display panel further comprises (2N+2) gate lines which are arranged along the first direction and configured to provide a gate scanning signal to the plurality of sub-pixel units;
• the pixel driving circuit in each first sub-pixel unit in an (n)th row of sub-pixel unit groups and the pixel driving circuit in each third sub-pixel unit in the (n)th row of sub-pixel unit groups are both connected with a (2n−1)th gate line of the (2N+2) gate lines to receive the gate scanning signal and use the gate scanning signal as a first scanning driving signal;
• the pixel driving circuit in each second sub-pixel unit in the (n)th row of sub-pixel unit groups and the pixel driving circuit in each fourth sub-pixel unit in the (n)th row of sub-pixel unit groups are both connected with a (2n)th gate line of the (2N+2) gate lines to receive the gate scanning signal and use the gate scanning signal as a second scanning driving signal;
• the sensing circuit in each first sub-pixel unit in the (n)th row of sub-pixel unit groups and the sensing circuit in each third sub-pixel unit in the (n)th row of sub-pixel unit groups are both connected with a (2n+1)th gate line of the (2N+2) gate lines to receive the gate scanning signal and use the gate scanning signal as a first sensing driving signal;
