1. An organic light-emitting display substrate comprising a passive matrix organic light-emitting display area, the organic light-emitting display substrate comprising:
a substrate;
an organic layer located on one side of the substrate, and comprising a plurality of grooves located at the passive matrix organic light-emitting display area, spaced apart along a first direction and extending along a second direction;
an anode layer located on a surface of the organic layer away from the substrate, and comprising:
a plurality of first anodes located at the passive matrix organic light-emitting display area and arranged in an array, and
a plurality of shielding portions located at the passive matrix organic light-emitting display area, spaced apart along the first direction and extending along the second direction, wherein materials of the plurality of shielding portions are the same as materials of the plurality of first anodes, orthographic projections of the plurality of shielding portions on the substrate and orthographic projections of the plurality of grooves on the substrate are distributed in gaps of orthographic projections of the plurality of first anodes on the substrate, which extend along the second direction, and an orthographic projection of each of the plurality of shielding portions on the substrate partially overlaps with an orthographic projection of a groove of the plurality of grooves on the substrate to form a plurality of partition grooves;
an organic functional layer located on one side of the anode layer away from the substrate; and
a cathode layer located on one side of the organic functional layer away from the substrate, and comprising a plurality of cathode strips and a plurality of cathode material portions, wherein the plurality of cathode strips and the plurality of cathode material portions are located at the passive matrix organic light-emitting display area, extend along the second direction and are alternately arranged along the first direction, each of the plurality of cathode strips is further away from the substrate than the anode layer, and each of the plurality of cathode material portions is located within a partition groove of the plurality of partition grooves and is not connected to an cathode strip of the plurality of cathode strips adjacent to the each of the plurality of cathode material portions,
wherein in the passive matrix organic light-emitting display area, any two of the plurality of first anodes adjacent to each other along the first direction are connected to each other through a first data metal layer or a second data metal layer, wherein the second data metal layer is connected to the first data metal layer through a plurality of first via holes and connected to the anode layer through a plurality of second via holes.
