1. A touch control structure, comprising a plurality of first mesh electrodes along a row direction and a plurality of second mesh electrodes along a column direction;
wherein the touch control structure is limited in a touch control region and absent in a window region surrounded by the touch control region;
wherein a window-crossing row of the plurality of first mesh electrodes comprises:
a first mesh block and a second mesh block respectively on a first side and a second side of the window region;
a first conductive plate directly connected to multiple mesh lines of the first mesh block;
a second conductive plate directly connected to multiple mesh lines of the second mesh block; and
a first conductive bridge connecting the first conductive plate and the second conductive plate;
wherein the first conductive plate, the second conductive plate, and the first conductive bridge are respectively around a first portion, a second portion, and a third portion of a periphery of the window region;
wherein the touch control structure further comprises:
a touch insulating layer between the first conductive bridge and the first conductive plate, and between the first conductive bridge and the second conductive plate; and
a first via and a second via respectively extending through the touch insulating layer, the first conductive bridge being respectively connected to the first conductive plate and the second conductive plate respectively through the first via and the second via;
wherein the first mesh block, the second mesh block, the first conductive plate, and the second conductive plate are in a same layer different from the first conductive bridge.
