Abstract
A display substrate is provided. The display substrate includes: a base substrate; a pixel defining layer disposed on the base substrate, wherein the pixel defining layer comprises a plurality of barriers and defines a plurality of sub-pixel areas, some or all of the barriers have grooves therein; and a touch structure disposed in the groove, wherein the touch structure is configured to provide a touch function.

A display substrate, comprising:
- a base substrate;
- a pixel defining layer disposed on the base substrate, wherein the pixel defining layer comprises a plurality of barriers and defines a plurality of sub-pixel areas, and some or all of the barriers have grooves therein;
- and
- a light-emitting unit, disposed on the plurality of sub-pixel areas;
- an encapsulating structure, disposed on a side of the light-emitting unit distal from the base substrate, wherein the encapsulating structure comprises at least a first inorganic sub-layer, an organic sub-layer, and a second inorganic sub-layer laminated in a direction going distal from the base substrate, the encapsulating structure covers the grooves of the pixel defining layer, wherein a portion of the at least one layer of the encapsulating structure for covering one of the grooves forms a depression;
- and
- a touch structure, disposed on a side of the pixel defining layer distal from the base substrate, wherein an orthographic projection of the touch structure on the base substrate at least partially overlaps orthographic projections of the grooves on the base substrate, and the orthographic projection of the touch structure on the base substrate at least partially does not overlap the orthographic projections of the grooves on the base substrate;
- wherein at least one layer of the encapsulating structure covers a portion of the grooves, and a vertical distance from a portion of a surface of the at least one layer covering the grooves to the base substrate is different from a vertical distance of a portion of a surface of the at least one layer covering the sub-pixel areas to the base substrate.
