    摘要： A pixel driving circuit includes a driving sub-circuit, a writing sub-circuit, a compensation sub-circuit and an adjustment sub-circuit. The driving sub-circuit is coupled to a first node, a second node, and a third node. The writing sub-circuit is coupled to the second node, a first scan signal terminal and a data signal terminal. The compensation sub-circuit is coupled to the first node, the third node and a compensation control terminal. The adjustment sub-circuit is coupled to the second node and/or the third node, a second scan signal terminal and a first reference voltage signal terminal. The adjustment sub-circuit is configured to, in a light-emitting adjustment phase, transmit a reference voltage signal received at the first reference voltage signal terminal to the second node and/or the third node under control of a scan signal transmitted by the second scan signal terminal.

    摘要： A display panel includes first circuit groups and gate signal lines. The first circuit groups are in a transition region and arranged along a first direction to form a first circuit row. One or more first circuit rows are arranged along a second direction. The first direction intersects the second direction. An i-th row of the first circuit rows in are electrically connected to an i-th gate signal line, and adjacent first circuit groups have a first spacing region. The first spacing region has a dimension of L1 along the first direction. A j-th row of the first circuit rows is electrically connected to a j-th gate signal line, and adjacent first circuit groups along the j-th gate signal line have a second spacing region. The second spacing region has a dimension of L2 along the first direction, where L1>L2.
