Patent ID: 8493347

Claim:
A touch display panel, comprising: a first substrate having a plurality of pixel structures disposed thereon; a second substrate disposed opposite to the first substrate; a light shielding pattern layer, disposed on the first substrate or the second substrate, wherein a plurality of pixel units are defined by the light shielding pattern layer, each pixel unit has a pixel edge length, and each pixel unit is disposed corresponding to one of the pixel structures on the first substrate; a touch sensing layer, disposed on the second substrate and comprising a plurality of first touch series and a plurality of second touch series, each first touch series and each touch series respectively having a plurality of mesh touch pads serially connected to each other, each mesh touch pad having a plurality of grid patterns, wherein each grid pattern has a grid edge length, the grid edge length is ⅛˜⅗ of the pixel edge length each grid pattern is twisting-cross-shaped, each twisting-cross-shaped grid pattern comprises four large quadrangles and one small quadrangle disposed in the center of the four large quadrangles, an angle between a bottom edge of each large quadrangle and a pixel edge of the pixel unit is 25˜65°, and an angle between a bottom edge of the small quadrangle and the pixel edge of the pixel unit is 25˜65°; and a display medium, sandwiched between the first substrate and the second substrate.
