Touch-control sensing pad 114 in the second area R2 is due to, being therefore transferred to drive electricity apart from drive circuit 102 farther out
The degree of the induced signal decay on road 102 is than more serious.Common by arranging second in the 3rd area R3 near drive circuit 102
Electrode 126, can cause the area of the touch-control sensing pad 114a in the first subregion SR1 to be less than the touch-control sensing pad in the second area R2
114 area, and then reduce in the second area R2 touch-control sensing in the signal intensity of touch-control sensing pad 114 and the first subregion SR1
The difference of the signal intensity of pad 114a, it is possible to decrease judge the difficulty of touch position.As shown in table 3, when the 3rd subregion SR3 is accounted for can
The area of vision area Rd too small or cross mostly cause in the second area R2 with the first subregion SR1 signal intensity difference reduce effect
Unevident.Furthermore, when the area of the first area R1 accounts for the scope of the area of visible area Rd for more than 3/5ths, suppression refers to touch-control letter more
Number coupling effect preferable.Comprehensive above two result, the area of the 3rd subregion SR3 and the first subregion SR1 of the present embodiment

The area for allowing for sensing is larger.Additionally, the 3rd subregion SR3 of the present embodiment is adjacent with the second area R2
Two touch-control sensing pads 114 are with " T-shaped " arrangement, that is, the 3rd subregion SR3 is arranged at wantonly two the first adjacent subregions
Between SR1, and take the part area of two first adjacent subregion SR1 respectively, and per one the 3rd subregion SR3 corresponding to the
Two touch-control sensing pads 114 in two area R2.By this kind of arrangement mode, compared to Wei Yu two the 3rd subregion SR3 between
Touch-control sensing pad 114c in first subregion SR1, the touch-control in the first subregion SR1 of visible area Rd left and right edges
The area that sensor pad 114b has is larger.Due to touch-control display panel generally the edge of visible area for touch-control sensing energy
Power is poor, and the second dummy common electrode 126 is not positioned adjacent to the present embodiment the position at visible area Rd edge, to avoid shadow
Ring touch-control ability of the touch-control display panel 3 at visible area Rd edge.Additionally, the first area R1 is optional with the 3rd area R3 in the present embodiment
