Touch substrate and display panel

A touch substrate comprising:

• a plurality of touch units, at least one first branch pattern, at least one second branch pattern, at least one third branch pattern, and at least one fourth branch pattern, wherein each of the touch units comprises a first electrode and a second electrode disposed electrically insulated from each other, four regions arranged in an array manner are defined in each of the touch units, a first connection center and a second connection center correspond to two central points of adjacent two of the regions;
• wherein the first electrode comprises:
• a first main branch electrode extending along a first direction, and
• the at least one first branch pattern and the at least one third branch pattern are respectively disposed on two sides of the first main branch electrode;
• wherein the second electrode comprises:
• a second main branch electrode extending along a second direction perpendicular to the first direction, and
• the at least one second branch pattern and at the least one fourth branch electrode are respectively disposed on two sides of the second main branch electrode;
• and
• wherein in the second direction, with the first connection center acting as a central point, and the first branch pattern diffuses toward two sides of the first connection center;
• and with the second connection center acting as a central point, and the second branch pattern diffuses toward two sides of the second connection center;
• in the first direction, with the second connection center acting as the central point, the third branch pattern diffuses toward two sides of the second connection center and encloses the second branch pattern;
• and with the first connection center acting as the central point, the fourth branch pattern diffuses toward two sides of the first connection center and encloses the first branch pattern.
