Claim 0:
1. A display substrate having at least one display region and at least one non-display region, a non-display region being located at at least one side of a display region, the display substrate comprising:
a base;
a plurality of light-emitting devices located in the at least one display region and disposed on a side of the base; and
an encapsulation layer disposed on a side, facing away from the base, of the plurality of light-emitting devices, and configured to encapsulate the plurality of light-emitting devices, wherein
a surface, proximate to the base, of a portion of the encapsulation layer located in the non-display region is unevenly arranged;
the display substrate further comprising a dielectric layer located in the at least one non-display region and disposed between the base and the encapsulation layer, wherein
a surface, facing away from the base of a portion of the dielectric layer located in the non-display region has a plurality of first grooves, the surface, proximate to the base, of the portion of the encapsulation layer located in the non-display region has a plurality of first protrusions, the plurality of first protrusions are in one-to-one correspondence with the plurality of first grooves, and an orthogonal projection of each first protrusion on the base is located within an orthogonal projection of corresponding first groove on the base;
wherein the display substrate has a plurality of pixel regions and non-pixel regions, a non-pixel region is located at at least one side of a pixel region; the plurality of pixel regions are arranged in an array, and the pixel region includes the display region and the non-display region; the non-pixel region includes a connection region and an opening region;
the display substrate further comprises a plurality of signal connection lines located in the connection region and a plurality of signal control lines located in the pixel region; at least one end of each signal connection line is connected to at least one corresponding signal control line in at least one adjacent pixel region;
portions, located in opening regions, of the base, the encapsulation layer, and any thin film located between the base and the encapsulation layer are hollowed; portions, located in connection regions, of the encapsulation layer are located on a side, facing away from the base, of the plurality of signal connection lines.
