1. A touch control component, comprising a plurality of touch control units, wherein each of the touch control units comprises a first electrode and a second electrode electrically insulated from each other;
the first electrode comprises:
a first main stem electrode extending along a first direction;
at least one first branch electrode extending from an intersection of the first main stem electrode and a second main stem electrode to a direction away from the first main stem electrode and the second main stem electrode; and
a plurality of first electrode extending parts;
the second electrode comprises:
the second main stem electrode extending along a second direction, and
at least one second branch electrode extending from the intersection of the first main stem electrode and the second main stem electrode to the direction away from the first main stem electrode and the second main stem electrode;
wherein the first electrode further comprises at least one third branch electrode extending from the first main stem electrode to the direction away from the first main stem electrode and the second main stem electrode and disposed adjacent to at least one of the at least one first branch electrode;
wherein one end of each of the first electrode extending parts is connected to a junction of the two adjacent third branch electrodes in the two of the touch control units adjacent to each other in the first direction, another end of each of the first electrode extending parts extends to a junction of two of the touch control units adjacent to each other in the second direction, and two of the first electrode extending parts adjacent to each other are electrically insulated from each other;
wherein each of the first electrode extending parts comprises a first electrode extending main stem part and two first electrode extending branch parts extending from the first electrode extending main stem part, an area surrounded by the two first electrode extending branch parts is provided with a third dummy electrode, and the third dummy electrode is electrically insulated from the first electrode;
the at least one second branch electrode surrounds the at least one first branch electrode corresponding to the at least one second branch electrode, and the at least one third branch electrode adjacent to the at least one first branch electrode surrounds the at least one second branch electrode positioned between the at least one first branch electrode and the at least one third branch electrode; and
in the first direction, two adjacent third branch electrodes respectively positioned in two of the touch control units adjacent to each other are connected to each other on one end away from the third branch electrodes connected to the first main stem electrode, and the first direction and the second direction are different.
