The invention discloses a kind of contact panel module, contact panel is applied to for example display device, tablet computer, intelligent
Mobile phone, notebook computer, desktop computer, TV, satellite navigation, display, aviation are put with display or portable DVD on car
The various electronic devices such as shadow machine, and the conductive film of contact panel be mostly tin indium oxide (Indium tin oxide, abbreviation
For ITO) film or silver nanowire film.And Touch Screen can be divided into resistance touch screen and capacitance touch control screen, its
Middle capacitance type touch-control panel, which mainly has, is produced on indium tin oxide (ITO) layer on glass, then is fitted in setting in strengthened glass
Meter, is known as GG (Glass Glass), also has indium tin oxide layer being produced on polyethylene terephthalate
On the film of (polyethylene terephthalate, PET) material, then the design being fitted in strengthened glass, it is known as GFF
(Glass Film Film).And the present invention focuses principally on bilayer film (Glass Film Film；GFF part).
Please refer to Fig.1 and Fig. 2, it illustrates the schematic perspective view of contact panel module provided by the present invention and combination respectively
Schematic diagram.Contact panel module 1 includes the first induction electrode layer 10 and the second induction electrode layer 20, it is tin indium oxide
(Indium tin oxide, simply referred to as ITO) film, that is to say, that be that indium tin oxide layer is produced on polyethylene to benzene
On the film of dicarboxylic acid esters (polyethylene terephthalate, PET) material, certainly, its material is not particularly limited,
Simply at present, on the market, the kenel that PET film is formed at ITO is most widely used.And the first induction electrode layer 10 and
Two induction electrode layers 20 have first electrode 11 with having plural number in second electrode 21, that is, the first induction electrode layer 10 respectively
First electrode 11, has plural second electrode 21 on the second induction electrode layer 20.
For example, the first induction electrode layer 10 can be reception (RX) electrode layer for being arranged at lower floor, and the second induced electricity
Pole layer 20 is then transmitting (TX) electrode layer for being arranged at upper strata, it is distributed in the induction region of contact panel, there is provided user
Sensing during operation, and around it is then the frame region of contact panel.By and large, first on the first induction electrode layer 10
Second electrode 21 on 11 and second induction electrode layer 20 of electrode, the online outline of its cloth are plumbness, and because it is subsequently needed
It is bonded to each other, in size, the first induction electrode layer 10 is also that outline is identical with the second induction electrode layer 20；It is identical
Ground, this part are only the example for coordinating schema to be explained, and are not limited to the kenel of its configuration, and in schema
Aspect is also merely signal, is not limited to the interest field that the present invention is intended to protect.
Then, there is the first then area (bonding area) 12, itself and the foregoing first electricity on the first induction electrode floor 10
Pole 11 is electrically connected and is easy to connect with external；It is identical, on the second induction electrode floor 10 also with second then area 22 with
Foregoing second electrode 11 is electrically connected.First induction electrode layer 10 and the second induction electrode layer 20 are mutual by the first glue-line 30
Fitting, wherein, 30 most common person of the first glue-line is OCA optical cements (Optical Clear Adhesive；OCA), it can be by
Ultraviolet light sticks together effect to be cured generation, at the same light transmittance it is high (>99%), therefore suitable for this type product then；
After making fitting, the first induction electrode floor 10 of lower floor first then area remain to expose, on the second induction electrode layer 10 in
Opening 23 is provided with corresponding position.
Continue, referring to Fig. 3, it illustrates the opening of contact panel module provided by the present invention and second electrode most short distance
From schematic diagram.Because of the relation of structure for this, opening 23 nearby necessarily becomes the opposite most weak position of adhesion, once shell
From certainly will be since adjacent domain, thus adjacent second electrode 21 can be influenced；In order to overcome this inborn limitation, the present invention will
The relative distance D increases of second electrode 21 and opening 23, in other words, set opening 23 and the beeline D of second electrode 21
It is calculated as more than 2.5 millimeters (mm), thus opening 23 can be greatly reduced and nearby peel off and influence the situation of second electrode 21, Jin Erzeng
Add the yield of production.
For in practice, with tin indium oxide (ITO) film or the laminated film being made of ito thin film and Copper thin film
For example, when the sheet resistance of the second induction electrode layer 20 is more than 70 ohm-sqs (ohm/sq) and less than or equal to 100
During ohm-sq, the beeline D preferablies of opening 23 and second electrode 21 are 2.5~3.5 millimeters；And when the second induced electricity
When the sheet resistance of pole layer 20 is less than or equal to 70 ohm-sqs (ohm/sq), the beeline D of opening 23 and second electrode 21
Preferably is 3.5~4.5 millimeters；This undesirable situation can thus be greatly reduced.
Then, referring to Fig. 4, the second glue-line 40 can be set on the second induction electrode layer 20 again, for follow-up gluing base
Plate (not shown), and form bilayer film (Glass Film Film；GFF kenel).Wherein, the material of substrate can be glass
Glass, or doped with polyethylene terephthalate (polyethylene terephthalate；The materials such as glass PET)；
Can be OCA optical cements and the second glue-line 40 is then identical with foregoing first glue-line 30.
In conclusion the contact panel module provided according to the present invention, its be by the opening of upper strata induction electrode layer with
The distance of its electrode widens, even if making it have peeling to be also unlikely to influence electrode, and then can improve overall yield, greatly
Width improves Industry Competitive Advantage.
Only as described above, is only the preferred embodiments of the invention, is not used for limiting the scope of implementation of the invention.
Therefore i.e. all features according to described in the present patent application scope and spiritual equivalent change or modification for it, it should all be included in the present invention's
