Touch display devices

Abstract

A touch display device includes a substrate. The substrate includes a display area, a non-display area, a first touch area, and a non-touch area. A first touch grid is disposed within the first touch area. A second touch grid is electrically isolated from the first touch grid and disposed within the first touch area. A first wire is disposed within the non-touch area and electrically connected to the first touch grid. A second wire is disposed within the non-touch area and electrically connected to the second touch grid. The first wire and the second wire are staggered and are electrically isolated from each other. The second wire includes at least two separate conductive units and at least one bridge wire connected to the at least two separate conductive units. An insulating layer is disposed between the first wire and the second wire.

What is claimed is: 
     
         1 . A touch display device, comprising:
 a substrate;   a touch grid disposed on the substrate, and comprising:
 a plurality of conductive structures; and 
 at least one bridge structure connected to at least two of the plurality of conductive structures; 
   wherein each of the at least two of the plurality of conductive structures has a plurality of openings.   
     
     
         2 . The touch display device as claimed in  claim 1 , further comprising another touch grid, wherein the at least one bridge structure overlaps a portion of the another touch grid. 
     
     
         3 . The touch display device as claimed in  claim 1 , further comprising another touch grid, wherein the touch grid and the another touch grid are staggered. 
     
     
         4 . The touch display device as claimed in  claim 1 , further comprising another touch grid, wherein the touch grid and the another touch grid are electrically isolated from each other. 
     
     
         5 . The touch display device as claimed in  claim 1 , further comprising another touch grid, wherein the touch grid and the another touch grid are separated by a gap. 
     
     
         6 . The touch display device as claimed in  claim 1 , further comprising a wire which is electrically connected to the touch grid. 
     
     
         7 . The touch display device as claimed in  claim 6 , further comprising another touch grid and another wire which is electrically connected to the another touch grid. 
     
     
         8 . The touch display device as claimed in  claim 7 , wherein the wire and the another wire are staggered.
