1. A display backboard, comprising:
a driving substrate;
a plurality of driving electrode groups on the driving substrate, wherein each of the plurality of driving electrode groups comprises a plurality of driving electrodes to be coupled to an electronic device comprising a plurality of electrode pins, and the number of the plurality of driving electrodes is identical to the number of the plurality of electrode pins;
a plurality of connection structure groups, each of which comprises a plurality of connection structures, wherein each of the plurality of connection structures is on one of the plurality of driving electrodes of the connection structure group,
wherein the connecting structure comprises:
at least one conductive component on the driving electrode, wherein an area of a first cross-section of the at least one conductive component is negatively correlated to a distance between the first cross-section and a surface of the driving substrate, and the first cross-section is parallel to the surface of the driving substrate; and
a restriction component on a side of the driving electrode provided with the at least one conductive component and at least in a part of a peripheral region of the at least one conductive component, wherein the restriction component protrudes from the driving electrode and has a first height in a direction perpendicular to the driving substrate.
