On the other hand, each bridging structure 124 of first sensing serials 120 of the present embodiment and the first sensor pad 122 and the second sensing serials 130 are for form simultaneously, and the material of each bridging structure 124 is different from the material of the first sensor pad 122.For example, each bridging structure 124 of the present embodiment for example comprises the first pattern 124a, and wherein the material of the first pattern 124a is for example nitride, the oxide of gold, silver, copper, aluminium, chromium, platinum, rhodium, molybdenum, titanium, nickel, indium, tin or its alloy or above-mentioned metal, one of them kind of oxides of nitrogen.Or the first pattern 124a can be also the conductive layer of multiple-level stack, and the material of conductive layer comprises above-mentioned at least two kinds.In addition, consider the sensing sensitivity of contact panel 100, the thickness Ha of the first pattern 124a is for example greater than
, to maintain certain electric conductivity.
Each optical match stacked structure 150 is disposed at each bridging structure 124 on user's surface.In the present embodiment, the surperficial S2 of the surperficial S1 with respect to its load-carrying unit of substrate 110 is for example touch surface, and in other words, user is sides that are positioned at surperficial S2 when operation contact panel 100.Therefore, each optical match stacked structure 150 of the present embodiment is for example disposed between substrate 110 and each bridging structure 124, but the utility model is not limited to this.In other embodiments, when surperficial S1 is touch surface, 124 of each bridging structures are disposed between substrate 110 and each optical match stacked structure 150.
Furthermore, each optical match stacked structure 150 comprises the first optical match pattern 152 and the second optical match pattern 154, and the second optical match pattern 154 is disposed between the first optical match pattern 152 and bridging structure 124, wherein the first optical match pattern 152 of the present embodiment and the second optical match pattern 154 have identical in fact profile, and optical match stacked structure 150 has identical in fact profile with bridging structure 124 (the first pattern 124a).Particularly, the sidewall of the first pattern 124a of each bridging structure 124 of the present embodiment is for example to trim with the sidewall of the first optical match pattern 152 and the second optical match pattern 154.
In the present embodiment, these bridging structures 124 and these optical match stacked structures 150, between insulation course 140 and substrate 110, make each connecting portion 134 cross over corresponding bridging structure 124 to be electrically connected adjacent two the second sensor pads 132.In addition, the sidewall of each bridging structure 124 and optical match stacked structure 150 is covered and contacts (as shown in Figure 2 A) by these the first sensor pads 122 of correspondence, and the sidewall of each insulation system 140 is covered and contact (as shown in Figure 2 B) by these connecting portions 134 of correspondence.
In the prior art, with metal material, make the bridging structure that connects two adjacent sensor pads, and this metal bridge connecting structure is built bridge also referred to as metal.The reflectivity that metal is built bridge is high, causes light to be reflected in metal bridge formation place major part, and cause contact panel for example, depending on effect bad (being to see bright spot in the region at metal bridge formation place).Therefore, the present embodiment is by arranging optical match stacked structure 150 at bridging structure 124 towards user's a side, and by refractive index and the extinction coefficient of the first pattern 124a and optical match stacked structure 150 are matched, use the reflectivity that reduces the first pattern 124a (bridging structure 124) region.
Particularly, because the first pattern 124a has relatively low light transmittance, and the light transmittance of optical match stacked structure 150 is greater than the light transmittance of the first pattern 124a relatively.Therefore, when light L by substrate 110 when the first sensing serials 120 is irradiated, light L can and expose to the first pattern 124a through optical match stacked structure 150.That is to say, optical match stacked structure 150 not is deliberately used for stopping the member of light L, but the member that can allow light L to pass through.For example, the light transmittance of optical match stacked structure is for example greater than 30%.In addition, because the first pattern 124a can provide a reflecting surface, so light L is not easy, by the first pattern 124a, to that is to say, when light L exposes to the first pattern 124a, will easily be subject to stopping of the first pattern 124a.Therefore, the present embodiment can consider to be positioned at the reflex that the rete of the first pattern 124a top causes light L, and can only consider to be positioned at the reflectivity of the optical match stacked structure 150 between substrate 110 and the first pattern 124a, judge the effect of looking at bridging structure 124 places, positions.
In the present embodiment, the extinction coefficient of the first optical match pattern 152 is k1, and refractive index is n1, and 0.2 * n1<k1<2 * n1, and the extinction coefficient of the second optical match pattern 154 is k2, refractive index is n2, and k2<0.05 * n2.Therefore,, when light L is when contact panel 100 irradiates, the present embodiment can reduce light L at the reflectivity of bridging structure 124 regions, and makes light L be less than 20% at the reflectivity of bridging structure 124 regions.In one embodiment, the thickness H1 when each the first optical match pattern 152 is
and the thickness H2 of each second optical match pattern 154 is
time, light L can further reduce and be less than 10% at the reflectivity of bridging structure 124 regions.

Because the optical match stacked structure 150 of the present embodiment can reduce light L at the reflectivity of bridging structure 124 regions by double-decker (refer to by the first optical match pattern 152 and the second optical match pattern 154 each other stacking double-decker), therefore, than prior art, by high and low refractive index, replace each other at least four layers of stacking blooming and reduce light at the reflectivity of metal bridge formation region, the present embodiment can reduce the required time of making of optical match stacked structure 150, and simplifies the loaded down with trivial details degree of making.
In addition, the optical match stacked structure 150 of the present embodiment replaces the traditional reduction of the mode (for example configuring light shield layer) with shading light L at the reflectivity of bridging structure 124 regions in the mode of optical match (referring to the design of extinction coefficient and refractive index), therefore the present embodiment contact panel 100 promotes and looks effect except reducing reflectivity, also can have concurrently attractive in appearance.
In the present embodiment, each bridging structure 124 can further comprise the second pattern 124b and the 3rd pattern 124c, and wherein the first pattern 124a is between the second pattern 124b and the 3rd pattern 124c.Particularly, the second pattern 124b is between the first pattern 124a and corresponding optical match stacked structure 150, and that the 3rd pattern 124c is positioned at the first pattern 124a is upper, and the first pattern 124a is between the 3rd pattern 124c and corresponding optical match stacked structure 150.
The second pattern 124b can be used for protecting the first pattern 124a, increase the structural strength of bridging structure 124, and it can also be used to increase the tack between the first pattern 124a and corresponding optical match stacked structure 150.In one embodiment, when the extinction coefficient of the second pattern 124b identical with the extinction coefficient of the first optical match pattern 152, and when the refractive index of the refractive index of the second pattern 124b and the first optical match pattern 152 is identical, the second pattern 124b also can have the effect of optical match.Thus, can further reduce light L at the reflectivity of bridging structure 124 regions, and promote the effect of looking of contact panel 100.
On the other hand, the 3rd pattern 124c also can be used for protecting the first pattern 124a, increases the structural strength of bridging structure 124 and avoid the first pattern 124a oxidation etc.In addition, the 3rd pattern 124c can also be used to increase the tack between the first pattern 124a and insulation system 140.Therefore, the material of the better adhesion effect of the optional apparatus of the 3rd pattern 124c, for example, be the material identical with the second pattern 124b.In addition, thickness Hb, the Hc of the second pattern 124b and the 3rd pattern 124c are for example less than
