Claim 12:
13. An organic light-emitting display panel, comprising:
a plurality of organic light-emitting units;
a first display area; and
a second display area;
wherein the plurality of organic light-emitting units comprises first organic light-emitting units in the first display area and second organic light-emitting units in the second display area;
wherein the first organic light-emitting units share a first cathode;
wherein the second organic light-emitting units comprise at least one organic light-emitting unit group, each comprising at least one organic light-emitting unit; wherein in a same organic light-emitting unit group comprising a plurality of organic light-emitting units, the plurality of organic light-emitting units in the same organic light-emitting unit group share a second cathode; wherein the second cathode has a zigzag edge segment;
wherein the organic light-emitting display panel further comprises: a negative-supply-voltage signal transmission line located in a bezel area of the organic light-emitting display panel,
wherein the second display area further comprises a conductive connection portion, wherein the conductive connecting portion is electrically connected to the negative-supply-voltage signal transmission line and the second cathode;
wherein the conductive connecting portion is electrically connected to the second cathode through a first via, and wherein the first via is located outside a light-emitting zone of each of the plurality of organic light-emitting units.
