Claim 0:
1. A display panel, comprising:
a display region, a non-display region bordering two sides of the display region at least in a first direction, and a hole-digging region,
wherein in the first direction, a distance from the hole-digging region to the non-display region on a first side of the display region is smaller than a distance from the hole-digging region to the non-display region on a second side of the display region, wherein the first side and the second side are opposite in the first direction;
wherein the display region comprises a plurality of pixel circuits and a plurality of initialization signal lines, wherein the plurality of pixel circuits are arranged in an array in the first direction and a second direction, the plurality of initialization signal lines are arranged in sequence in the second direction, and at least part of the plurality of initialization signal lines each has a partial line segment extending around the hole-digging region, wherein the second direction intersects the first direction;
wherein the non-display region comprises a plurality of cascaded initialization signal shift register units, wherein the plurality of initialization signal shift register units are electrically connected to the plurality of initialization signal lines in a one-to-one correspondence, and the plurality of initialization signal shift register units are configured to provide initialization signals to the plurality of pixel circuits through the plurality of initialization signal lines in an initialization stage;
wherein the plurality of initialization signal shift register units comprise a first initialization signal shift register unit located in the non-display region on the first side of the display region in the first direction, and the first initialization signal shift register unit is electrically connected to an initialization signal line that has a partial line segment extending around the hole-digging region and corresponds to the first initialization signal shift register unit;
wherein the plurality of initialization signal shift register units comprise a second initialization signal shift register unit located in the non-display region on the second side of the display region in the first direction, and the second initialization signal shift register unit is electrically connected to an initialization signal line that has a partial line segment extending around the hole-digging region and corresponds to the second initialization signal shift register unit; and
wherein in the initialization stage, an absolute value of a first initialization signal provided by the first initialization signal shift register unit is smaller than an absolute value of a second initialization signal provided by the second initialization signal shift register unit.
