Display substrate, display panel, and display apparatus

A display substrate, comprising:

• a base substrate comprising:
• a display region comprising:
• a first display region;
• and
• a second display region at least on one side of the first display region;
• and
• a frame region surrounding the display region;
• wherein light transmittance of the first display region is greater than light transmittance of the second display region;
• a drive circuit layer, located on the base substrate and comprising:
• a plurality of first pixel circuits;
• and
• a plurality of second pixel circuits;
• wherein orthographic projections of the plurality of first pixel circuits on the base substrate do not overlap an orthographic projection of the first display region on the base substrate, and the plurality of second pixel circuits are in the second display region;
• a light-emitting device layer, located on one side of the drive circuit layer facing away from the base substrate and comprising:
• a plurality of first light-emitting devices in the first display region;
• and
• a plurality of second light-emitting devices in the second display region;
• wherein:
• the plurality of first light-emitting devices comprises:
• a plurality of first anodes independently arranged;
• the plurality of second light-emitting device comprises:
• a plurality of second anodes independently arranged;
• wherein the plurality of first anodes each is electrically connected with a respective one of the plurality of first pixel circuits, and the plurality of second anodes each is electrically connected with a respective one of the plurality of second pixel circuits;
• and
• a density of the plurality of first light-emitting devices in the first display region is same as a density of the plurality of second light-emitting devices in the second display region;
• and
• at least one transparent conducting layer between the drive circuit layer and the light-emitting device layer;
• wherein each layer of the at least one transparent conducting layer comprises:
• a plurality of first anode wires electrically connected with the first anodes;
• wherein the first anode wire at least comprises:
• a first portion extending in a column direction;
• and
• a second portion extending in a row direction;
• wherein the second portions of one first anode wire electrically connected with one first anode in a row and the second portion in the row are located between different pairs of two adjacent rows of first anodes, and the second portions are led out in the row direction to an outside of the first display region.
