The limitation present invention.In figure, the similar unit of structure is represented with identical label.
Fig. 3 is refer to, Fig. 3 is the structural representation of the touch display panel of the present invention；
The touch display panel of the present invention is as shown in figure 3, including a plurality of drives line 21, a plurality of sense wire 22, touch chip
(not shown), metal shell 24, the drives line 21 is used for receiving drive signal；The sense wire 22 and the drives line
21 insulation are staggered, i.e., without electric connection；For example the sense wire 22 is arranged in X direction, and the drives line 21 is arranged along Y-direction
Cloth, the drives line 21 and the vertical interlaced of sense wire 22.The sense wire 22 and drives line 21 interlocked by mutually insulated
Sensing array can be formed.The sense wire 22 is used for being grasped according to the drive signal in the drives line 21 and the touch-control sensed
Make, produce detection signal.
The touch chip includes driver element and detection unit (not shown), the driver element and the driving
Line 21 is connected, and the driver element is used for providing drive signal to the drives line 21；The detection unit and the sense wire
22 connections, the detection unit judges whether there is the touch control operation on the touch display panel according to the detection signal,
Generate judged result.
With reference to Fig. 4, Fig. 4 provides the enlarged perspective in 102 regions in Fig. 3；Drives line 21 and sense wire 22 are by positioned at tactile
The cabling 25 for touching region exterior is connected to touch area 26 from the touch display panel left and right sides and formed, and these cablings 25 are by soft
Property to stencil printed circuit board (FPC) firmly to be connected to 102 regions in touch chip, figure be the area between touch area to metal shell
Domain.
The metal shell 24 is located at the outside of the touch chip, the distance between the metal shell 24 and reference line
Less than preset value, wherein the reference line is that metal shell 24 described in distance is most in the drives line 21 or the sense wire 22
Near line, is the cabling closest to the metal shell 24；The preset value is less than metal shell in the prior art and reference
The distance between line, i.e., less than the L1+L2 in Fig. 1, the touch chip has earth terminal, and the metal shell 24 is touched with described
The earth terminal connection of chip is touched, to avoid noise from disturbing the signal in the drives line and the sense wire.
It is by setting a ground wire in the outside of sense wire and drives line, being asked the interference that solves noise in the prior art
Topic, and the present invention replaces the ground wire with metal shell, directly can set metal shell at the edge of indium tin oxide films 27, from
