One side at window substrate 110 can form design level 120.Design level 120 can be formed on the outside of area of visual field VA, and design level 120 can form edge along window substrate 110 around area of visual field VA.At this moment, design level 120 can be formed on the rear surface in the two sides of window substrate 110.For example, design level 120 can process black material and is formed.
On the other hand, electrode assembly 200 is that electrode assembly 200 comprises transparent electrode pattern 210 and wiring pattern 220 for embodying the electrode structure of touch sensor according to an embodiment of the invention.Transparent electrode pattern 210 is formed on the area of visual field VA of window substrate 110, and wiring pattern 220 is formed on the outside of area of visual field VA.
With reference to Fig. 2 to Fig. 4, first the area of visual field VA at contact panel forms transparent electrode pattern 210.Transparent electrode pattern 210 can carry out at an evaporation transparent conductive body of window substrate 110 composition or printing forms.Carbon nano-tube), graphite monoatomic layer, wire netting (metal mesh) etc. have the transparent material of electric conductivity nano silver wire), CNT(carbon nano tube for example, transparent conductive body can be ITO, SNW(silver nano wire::.
Thereupon, form the transparent electrode pattern 210 as shown in Fig. 2 to Fig. 4 is exemplary.At this moment, transparent electrode pattern 210 forms the outside that extends to area of visual field VA, to comprise the part overlapping along the vertical direction with the wiring pattern 220 forming afterwards.
Then, on transparent electrode pattern 210, form insulating sticky paste layer 230 and a part for transparent electrode pattern 210 is exposed.And, form above it wiring pattern 220.
Insulating sticky paste layer 230 can be formed by the material that has electrical insulating property and have a cementability, and wiring pattern 220 can form by the good such metal of silver of printing conductive.
Insulating sticky paste layer 230 can be formed on the part of wanting mutually insulated in the region that comprises transparent electrode pattern 210 and the overlapping along the vertical direction part of wiring pattern 220.That is, insulating sticky paste layer 230 between transparent electrode pattern 210 and wiring pattern 220 and optionally electrical isolation transparent electrode pattern 210 and wiring pattern 220 placed separately.
At this moment, insulating sticky paste layer 230 can form and have the pattern that comprises that region S mutual overlapping along the vertical direction in transparent electrode pattern 210 and wiring pattern 220 and contact site C that be electrically connected to is all exposed.; according to embodiments of the invention; at the region S that comprises the contact site C that transparent electrode pattern 210 and wiring figure line 220 are overlapping along the vertical direction and be electrically connected to, all do not form insulating sticky paste layer 230; there is the structure that directly forms wiring pattern 220 on transparent electrode pattern 210, so improve adhesion force.
On the other hand, with reference to Fig. 2 and Fig. 3, transparent electrode pattern 210 can comprise a plurality of transparent electrode pattern lines 211, and a plurality of transparent electrode lines 211 can extend along direction mutually arranged side by side.And wiring pattern 220 also can comprise a plurality of wiring pattern lines 221, a plurality of wiring pattern lines 221 can extend along direction mutually arranged side by side.At this moment, a plurality of transparent electrode pattern lines 211 and a plurality of wiring pattern line 221 can be along the roughly direction at right angle prolongations each other mutually.
At this moment, as shown in Figure 2, in a plurality of transparent electrode pattern lines 211 and a plurality of wiring pattern line 221, overlapping and mutual electrical connection along the vertical direction contact site C proper alignment becomes linearly, and insulating sticky paste layer 230 can comprise with step form and forms and make to comprise the stage portion 231 that the region S of the contact site C of this electrical connection exposes.
In other words, the inside portion that insulating sticky paste layer 230 can form the transparent electrode pattern 211 that exists only in from reporting to the leadship after accomplishing a task along the vertical direction and wiring pattern line 221 assign to the contact site C that comprises overlapping along the vertical direction transparent electrode pattern line 211 and wiring pattern line 221 and mutual electrical connection region S before till part.
Form by this way insulating sticky paste layer 230, thereby the part being electrically connected to the overlapping along the vertical direction of transparent electrode pattern 210 and wiring pattern 220, transparent electrode pattern 210 exposes completely and surface is direct thereon forms wiring pattern 220, thereby can improve adhesion force.
On the other hand, with reference to Fig. 5 to Fig. 7, the electrode assembly according to other embodiments of the invention is described.
In the present embodiment, transparent electrode pattern line 211 and wiring pattern line 221 can form and Fig. 2 and illustrated similar mode and the form of Fig. 3.
At this moment, with reference to Fig. 5 to Fig. 7, a plurality of transparent electrode pattern lines 211 become linear with overlapping and mutual electrical connection along the vertical direction contact site C proper alignment in a plurality of wiring pattern lines 221, and insulating sticky paste layer 240 can be divided into a plurality of parts of the region of the contact site C that comprises electrical connection being exposed and form.That is,, in the present embodiment, at Fig. 2 to Fig. 4, there is the form that part between transparent electrode pattern line 211 does not form insulating sticky paste layer 240.
More than, preferred embodiment of the present invention is at length illustrated, but interest field of the present invention is not limited to this, those of ordinary skills of claims definition below utilize the various distortion of key concept of the present invention and improvement form also to belong to claim scope of the present invention.
