19 Claims

1. A touch structure, comprising: a plurality of first mesh electrodes extending in a first direction and a plurality of second mesh electrodes extending in a second direction intersecting the first direction,

wherein the touch structure is defined in a touch region and is absent in a window region surrounded by the touch region;

wherein the plurality of first mesh electrodes comprise at least one cross-window row separated by the window region, the at least one cross-window row comprises a first cross-window row and the first cross-window row comprises:

a first window mesh block adjacent to the window region and on a first side of the window region;

a first conductive plate directly connected to a plurality of mesh lines of the first window mesh block; and

a first non-window mesh block on a side of the first window mesh block away from the window region;

wherein the plurality of second mesh electrodes comprise at least one cross-window column separated by the window region, the at least one cross-window column comprises a first cross-window column and the first cross-window column comprises:

a second window mesh block adjacent to the window region and on a second side of the window region;

a second conductive plate directly connected to a plurality of mesh lines of the second window mesh block; and

a second non-window mesh block on a side of the second window mesh block away from the window region;

wherein the first and second conductive plates extend along first and second portions of a periphery of the window region, respectively;

an area of the first conductive plate is positively correlated to that of a missing portion of the first window mesh block with respect to the first non-window mesh block, and an area of the second conductive plate is positively correlated to that of a missing portion of the second window mesh block with respect to the second non-window mesh block,

the first cross-window column further comprises a first conductive bridge and a second conductive bridge, and

a first end of the first conductive bridge is directly connected to a first end of the second conductive plate, and a first end of the second conductive bridge is directly connected to a second end of the second conductive plate opposite to the first end; and

the first cross-window row further comprises:

a third window mesh block adjacent to the window region and on a third side of the window region opposite to the first side;

a third conductive plate directly connected to a plurality of mesh lines of the third window mesh block and extending along a third portion of the periphery of the window region; and

a third conductive bridge connecting a first end of the first conductive plate and a first end of the third conductive plate together,

wherein the second side is between the first side and the third side.
