Utility model content
Technical problem to be solved in the utility model is to provide a kind of individual layer multipoint mode capacitive touch screen, is intended to improve the anti-ESD ability at wire jumper via hole place in individual layer multipoint mode capacitive touch screen.
The utility model is to realize like this, a kind of individual layer multipoint mode capacitive touch screen, it only comprises a laminar substrate, on described substrate, be laid with drive electrode pattern and the induction electrode pattern that can form capacitance structure, on drive electrode signal lead outside described individual layer multipoint mode capacitive touch screen viewing area or induction electrode signal lead region, with an insulation course, on described insulation course, there are some silver slurry signal lead; Described insulation course is provided with some circular wire jumper via holes, and described drive electrode signal lead or induction electrode signal lead cause corresponding silver slurry signal lead by described circular wire jumper via hole.
Further, described drive electrode signal or induction electrode signal lead are positioned at the position at described circular wire jumper via hole place, and increase attached toroidal bottoming silver slurry layer at circular wire jumper via hole place, and the diameter of toroidal bottoming silver slurry layer is less than circular wire jumper via hole.
Further, the ITO cabling of described drive electrode signal or induction electrode signal is just rounded to the position at described circular wire jumper via hole place, and its round diameter is larger than the diameter of described circular bottoming silver slurry layer.
Further, just the round diameter size of the circular position to described circular wire jumper via hole place is consistent with the diameter of described circular wire jumper via hole for the cabling of described drive electrode signal lead or described induction electrode signal.
Further, described drive electrode signal lead and induction electrode signal lead are ITO cabling.
The utility model compared with prior art, beneficial effect is: by by wire jumper Via Design for circular, can increase the contact area of silver slurry and electrode (as ITO), even can make silver slurry contact completely with electrode, thereby can increase the ability of wire jumper via hole to ESD electric current.In addition, the design of toroidal bottoming silver slurry layer can reduce the silver slurry and the ITO cabling contact impedance that drives or respond at wire jumper via hole place, effectively prevent because ESD electric charge is at the accumulation burn ITO of wire jumper via hole place electrode cabling the technological problems such as ITO lead rupture also can prevent from toasting time.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the wire jumper via hole cabling design of the individual layer multipoint mode capacitive touch screen that provides of the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The individual layer multipoint mode capacitive touch screen that the utility model provides is laid electrode pattern based on a substrate, as ITO electrode pattern, specifically comprises drive electrode signal lead and induction electrode signal lead, and the two can form capacitance structure.It is limited that the two-dimensional touch sensors of this kind of individual layer wiring is limited to substrate area, be not easy to directly bind FPC(Flexible Printed Circuit, flexible circuit board), generally need to enclose insulation course on the drive electrode signal lead of exterior domain or induction electrode signal lead in the visible area of individual layer multiple spot capacitive transducer, will state drive electrode signal lead or induction electrode signal lead and cause corresponding silver slurry signal lead on insulation course by wire jumper via hole and bind again FPC.
As shown in Figure 1, in the utility model, this insulation course is provided with some circular wire jumper via holes 1, and drive electrode signal lead or induction electrode signal lead 2 are all led on this insulation course and are connected with corresponding silver slurry cabling 3 by this circle wire jumper via hole 1.With respect to the design of square wire jumper via hole, this kind of circular wire jumper via hole 1 is larger with the ITO signal lead contact area of insulation course below, and the utility model advises that circular wire jumper via hole 1 diameter is more than or equal to 0.7mm, to guarantee that silver slurry contacts with ITO signal lead completely (if circular wire jumper via hole 1 is too little, may make the silver slurry 11 of filling in circular wire jumper via hole 1 not exclusively contact with drive electrode signal lead or induction electrode signal lead 2 because insulation course exists step), increase circular wire jumper via hole 1 ability of ESD electric current excessively.
As another improvement of the present utility model, in drive electrode signal lead and induction electrode signal lead 2 in the position that is positioned at circular wire jumper via hole place 1, increase attached toroidal bottoming silver slurry layer 4, the diameter of this toroidal bottoming silver slurry layer 4 is than the little 0.2-0.3mm of circular wire jumper via hole 1.Circular wire jumper via hole 1 place's silver slurry cabling can with increase attached toroidal bottoming silver slurry layer 4 and contact.First the design of bottoming silver slurry layer 4 can reduce by 1 ITO of place of circular wire jumper via hole place and the silver-colored contact impedance of starching cabling, can effectively prevent from jumping hole place accumulation burn ITO cabling because of ESD electric charge, secondly, when bottoming silver slurry layer can prevent from toasting, ITO fracture waits technological problems.
In addition, the cabling of drive electrode signal lead or induction electrode signal is just rounded to the position at circular wire jumper via hole 1 place, the circular ITO electrode cabling 5 of this position is specifically teardrop shaped, and its round diameter is consistent with the diameter of circular wire jumper via hole 1, the diameter of circular ITO electrode cabling 5 is than the large 0.2-0.3mm of the diameter of bottoming silver slurry layer 4, this kind of design can have following effect: thus prevent that fabrication error or the 4 area conferences of bottoming silver slurry layer from causing silver slurry 11 that 1 place of circular wire jumper via hole place fills and effective contact area of the circular ITO electrode cabling 5 burn ITO electrode cabling that diminishes, because the impedance of silver slurry is little, ESD electric current can preferentially directly not starched 11 by silver and flow to, but can preferential flow through the bottoming silver slurry layer 4 ITO electrode cabling of flowing through again, now the just 0.1mm of effective length of circular ITO electrode cabling 5 and silver slurry 11, will cause ESD to burn out ITO electrode cabling.And circular ITO electrode cabling 5 designs at circular wire jumper via hole 1 place can be in limited space, increase the contact area of circular ITO electrode cabling 5 and silver slurry 11 on ESD direction of current, thereby effectively prevent the silver slurry 11 and the too small ESD burn of circular ITO electrode cabling 5 contact area ITO problem that cause because of fabrication error.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
