Specific embodiment
Technology contents, construction feature, the objects and the effects for detailed description technical solution, below in conjunction with specific reality
It applies example and attached drawing is cooperated to be explained in detail.
Please refer to Fig. 1 a, Fig. 1 a is presented: public electrode (BC, ITO1) is divided into M*N by existing In-cell framework panel
A unit, is multiplexed with touch control unit；Wherein each touch control unit contains m*n sub-pixel (sub-pixel).Prior art processes stream
Journey is as shown in Figure 1 b: GE (gate metal) → GI (gate insulating layer) → SE (semiconductor layer) → ES (etch-stop
Layer) → SD (source/drain metal) → PV (third insulating layer) → OC (planarization layer) → CM (touch-control cabling metal) → VA
(the 4th insulating layer) → BC (public/touch control electrode) → CH (the 5th insulating layer) → PE (pixel electrode).And existing touch-control simultaneously
The overlap joint setting of its touch control unit cabling of display screen can refer to Fig. 2 a, Fig. 2 b: touch-control/public electrode (BC, ITO1) passes through via hole
Bridge joint overlaps (touch line) with touch-control cabling CM, and the touch-control cabling other end is overlapped with IC PIN, i.e. touch-control/display function letter
It number is provided by IC, is transmitted to BC square by touch-control cabling CM；As shown in the figure, CM cabling in part is (dark-grey curved by VA via hole
Bent portions) BC square linked into the end IC, extra CM takes sectional design (design of non-through formula)；Each BC touch control unit
It can be realized by single, double, more CM and be electrically connected with IC.
In the embodiment of the present invention program, referring to Fig. 3, for a kind of novel antistatic touch screen, with the prior art
The improvement is that, 1, touch-control CM cabling or use Winding Design in via regions through CM cabling, likewise, Gate/
Data cabling will be also routed around hole.2, can also script segmented CM be arranged to continuous CM cabling, and passed as electrostatic ring
Conducting wire.3, it by taking electrostatic ring/conduct piece is arranged in GE as an example, shows such as the touch screen structure in figure.Optionally, electrostatic ring can be
GE/SD/CM single layer, the public electrical connection of bilayer or multiple layer metal are arranged.In this embodiment, our through-holes in screen
Outer is provided with conduct piece, i.e. conduct piece surrounds the through-hole setting, and conduct piece connect with the first touch-control cabling, please refers to here
Fig. 4, the first touch-control cabling are the touch function line that electrostatic ring is connect with upper periphery lead in left figure top, first touch-control
Cabling metal is also connect with peripheral leads, and the peripheral leads are for eliminating charge.Peripheral leads in figure are that GND ground connection is walked
Line, of course for eliminating electrostatic charge, by the leads such as VGL, VGH or Vcom as electrostatic dissipation lead be also it is optional in real time just
Formula.Fig. 4 also illustrates the cross section view at via hole, and CM cabling is connect inside panel with conduct piece, the part drawn outside
It is connect with GND ground line.
In further embodiment, Fig. 4 and Fig. 5 is please referred to, further includes the second touch-control cabling, the second touch-control cabling packet
Include with the first touch-control cabling parallel section and be set to the winding portion of conduct piece periphery.It will be seen that at least from figure
There is the connection of the outer up and down of a touch-control cabling and panel, the most short connection path of straight line of script setting is blocked by through-hole, needed
Coiling is set, it may be seen that the second touch-control cabling of through-hole top and the bottom is parallel with the first touch-control cabling, and has been arrived logical
When near hole, we are by taking through-hole is circular hole as an example, then the second touch-control cabling near through-hole has been arranged to concentric with through-hole
Circular arc.To which the design has reached the technical effect for reducing electrostatic charge and being arranged through cabling.Certainly, when through-hole is arranged to
When oval, rectangular, rectangle, diamond shape, conduct piece may be set to be annulus, rectangle, elliptical ring or diamond shape etc..In this way, the
The winding portion of two touch-control cablings may be set to be the setting mutually unified with above-mentioned shape, to reach beautiful, facilitate production
Effect.
In our scheme, the CM cabling that electrostatic ring is electrically connected can contact setting simultaneously for single, double joint or more,
It can be set in part, lower part or up and down direction on electrostatic ring while being arranged.Further in embodiment as shown in Figure 5, also
Including third touch-control cabling, the third touch-control cabling is connect with conduct piece, and the third touch-control cabling includes and the first touch-control
With the part of straight line, the third touch-control cabling also connect with peripheral leads cabling.It may be seen that above and below the conduct piece of Fig. 5
It is connect respectively with touch-control cabling, externally draws charge simultaneously by more cablings.In an alternative scenario, the first touch-control cabling with
The attribute of the peripheral leads of third touch-control cabling is not consistent, such as piece-root grafting a GND, piece-root grafting VGL etc..Also it can reach elimination
The effect of through-hole ambient static electricity charge on screen.By the above-mentioned plan of establishment, it can guarantee screen while conducting ring is set
On touch signal line everywhere normal effect.
In some other further embodiment, as shown in fig. 6, the first touch-control cabling passes through panel overpass and conduct piece
Connection.Similarly, other touch-controls CM cabling can also be bridged by being similarly arranged.It will be seen that leading from Fig. 6
It is electrically connected on electric part/electrostatic ring with part touch-control CM cabling, another part touch-control CM cabling is connect with peripheral leads, two parts
The overlap joint of wire jumper is carried out between touch-control CM cabling by BC material or PE material, this design there can be following benefit, first can
Enough to save the space for being not provided with cabling in electrostatic ring nearby a certain range, secondly it is also possible that the contact tool at bridge joint both ends
There is lateral distance, is being not at the bridge joint for also completing signal between collinear two longitudinal cablings, it is more abundant
The type of cabling.
It should be noted that being not intended to limit although the various embodiments described above have been described herein
Scope of patent protection of the invention.Therefore, it based on innovative idea of the invention, change that embodiment described herein is carried out and is repaired
Change, or using equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content, it directly or indirectly will be with
Upper technical solution is used in other related technical areas, is included within scope of patent protection of the invention.
