In some embodiments, the first sub-electrode has a curved edge.

In some embodiments, each of at least part of the plurality of second touch electrodes includes a plurality of second electrodes disposed along a second direction and a third connection part connecting adjacent second electrodes, the third connection part is insulated from the first connection part and an orthographic projection of the third connection part on a plane parallel to the touch substrate partially overlaps an orthographic projection of the first connection part on the plane.

In some embodiments, each of at least part of the plurality of second electrodes includes two second sub-electrodes disposed along the second direction and a fourth connection part connecting the two second sub-electrodes, and the two second sub-electrodes are spaced apart from each other by a second gap extending along the first direction and between the two second sub-electrodes.

In some embodiments, the fourth connection part includes at least one third connection line extending along the second direction and configured to connect the two second sub-electrodes belonging to a same second electrode, and the third connection line has a curved line shape.

In some embodiments, the at least one third connection line and the at least one first connection line are disposed in a same layer.

In some embodiments, the second sub-electrode has a curved edge.

In some embodiments, the at least one first connection line and the first electrode are made of a same material.

In some embodiments, an included angle between any two adjacent segments of the first connection line having the curved line shape is larger than 90° and less than 180°.

In another aspect, the present disclosure further provides a touch apparatus, including any one of the touch substrates described herein.

In another aspect, the present disclosure further provides a method of manufacturing a touch substrate, including forming a first touch electrode on a base substrate, the first touch electrode being formed to include a plurality of first electrodes along a first direction and a first connection part connecting adjacent first electrodes, the first connection part being formed to include at least one first connection line extending along the first direction and configured to connect two first electrodes adjacent in the first direction, the first connection line having a curved line shape; forming a second touch electrode on the base substrate, the second touch electrode being formed to intersect with the first touch electrode.

In some embodiments, the second touch electrode is formed to include a plurality of second electrodes disposed along a second direction and a third connection part connecting adjacent second electrodes, the third connection part being insulated from the first connection part and an orthographic projection of the third connection part on the base substrate partially overlapping an orthographic projection of the first connection part on the base substrate; the first touch electrode and the second touch electrode are formed simultaneously, and forming the first touch electrode and the second touch electrode includes: forming a pattern of the first electrode, a pattern of the second electrode and a pattern of the third connection part on the base substrate; forming a pattern of an insulation layer on a side of the pattern of the third connection part away from the base substrate; and forming a pattern of the at least one first connection line on a side of the insulation layer away from the base substrate.

In some embodiments, the first electrode is formed to include two first sub-electrodes disposed along the first direction and a second connection part connecting the two first sub-electrodes, and a first gap extending along a second direction is formed between the two first sub-electrodes; the second electrode is formed to include two second sub-electrodes disposed along the second direction and a fourth connection part connecting the two second sub-electrodes, and a second gap extending along the first direction is formed between the two second sub-electrodes; forming the pattern of the first electrode, the pattern of the second electrode and the pattern of the third connection part on the base substrate includes forming a pattern of the first sub-electrode, a pattern of the second sub-electrode and the pattern of the third connection part by a single patterning process; forming a pattern of the second connection part and a pattern of the fourth connection part by a single patterning process, wherein the single patterning process for forming the pattern of the second connection part and the pattern of the fourth connection part and a patterning process for forming the pattern of the at least one first connection line are a same patterning process.
