Return Figure 1A, in one or more embodiment of the utility model, after whole contact panel receives an incident light, the first optical compensation films can be in harmonious proportion incident light through each layer of contact panel (as sensing electrode layer etc.) the tone of reflected light that formed.Thus, first optical compensation films 120 is compensated the difference in reflectivity caused because of patterning process in sensing electrode layer 110, be laid with electrode pattern layer 112, collets 114, connecting line 116 (with reference to Fig. 2 A) region with do not lay electrode pattern layer 112, collets 114, connecting line 116 (with reference to Fig. 2 A) the reflectivity difference of region under the light of height band wavelength less, use the reflected light tone access expansion light effectively adjusting contact panel 100 and reflect in the face of external light source, and can not be partially blue or partially yellow.
In addition, tradition has less energy gap in order to the material (such as niobium oxide, titanium dioxide) carrying out optical compensation, is easily subject to UV-irradiation and electronic transition and then those materials conductive.In one or more embodiment of the utility model, have absorbing material by arranging the first optical compensation films 120, the light energy conversion of absorption can be that heat energy disengages by this absorbing material.Thus, by configuration through the ultraviolet light of the first optical compensation films 120 will be that heat energy disengages by absorbing, the absorbing material in the first optical compensation films 120 or other materials can be prevented to be subject to UV-irradiation and excitation electron transition, and then to avoid the first optical compensation films 120 to conduct electricity.
Thus, because the stacking design of the first optical compensation films 120 is compensated the difference in reflectivity caused because of patterning process in sensing electrode layer 110, and the material that the first optical compensation films 120 has Absorbable rod ultraviolet light wave band irradiates and the problems such as generation conduction to avoid being subject to ultraviolet light wave band, therefore, present embodiment can promote fiduciary level and the optical quality of contact panel 100 simultaneously.
It is the sectional view of the contact panel 100 of another embodiment according to the utility model with reference to Fig. 3, Fig. 3.Present embodiment is similar to the embodiment of Figure 1A, difference is: the contact panel 100 of present embodiment more comprises the second optical compensation films 130, second optical compensation films 130 is arranged at the opposite side of relative first optical compensation films 120 of sensing electrode layer 110, in other words, the first optical compensation films 120 of present embodiment and the second optical compensation films 130 are the relative both sides being arranged at sensing electrode layer 110.Specifically, the first optical compensation films 120 of present embodiment is arranged on sensing electrode layer 110, and the second optical compensation films 130 is arranged under sensing electrode layer 110.
Specifically, the second optical compensation films 130 also comprises at least one fourth reflect rate layer 134 of at least one third reflect rate layer 132 and quantity equity, wherein the 4th penetrates rate layer 134 and comprises this second absorbing material; And the refractive index of third reflect rate layer 132 is relatively lower than the refractive index of fourth reflect rate layer 134.Third reflect rate layer 132 and fourth reflect rate layer 134 are with the direction away from sensing electrode layer 110, and first low folding is staggeredly stacked on sensing electrode layer 110 higher folding.
Second optical compensation films 130 and the first optical compensation films 120 are arranged in pairs or groups and form optical match with sensing electrode layer 110.In this, the quantity of configuration third reflect rate layer 132 can be respectively 1,2,3 layer even more, and the quantity of fourth reflect rate layer 134 is corresponding relative with the quantity of third reflect rate layer 132.It is noted that the first optical compensation films 120 and the second optical compensation films 130 repeatedly structure can be identical or different.Second optical compensation films 130 can be arranged on sensing electrode layer 110 directly or indirectly.
With aforementioned first refractive rate layer 122 and the second index layer 124 similarly, second absorbing material of the second optical compensation films 130 can be silicon nitride (Si3N4) or silicon oxynitride (SiON) or its combination, and namely the material of fourth reflect rate layer 134 can be silicon nitride (Si3N4) or silicon oxynitride (SiON) or its combination.On the other hand, in present embodiment, the material of third reflect rate layer 132 can be monox (SiO2) or magnesium fluoride (MgF2) or its combination.It is noted that the material of the first optical compensation films 120 and the second optical compensation films 130 can be identical or different.
With aforementioned first refractive rate layer 122 and the second index layer 124 similarly, in one or more embodiment of the utility model, the refractive index of third reflect rate layer 132 is 1.3 to 1.55, and the refractive index of fourth reflect rate layer 134 is 1.6 to 2.5.The thickness of third reflect rate layer 132 is 10 nanometer to 50 nanometers, and the thickness of fourth reflect rate layer 134 is 5 nanometer to 20 nanometers.
Need remark additionally, the thickness of sensing electrode layer 110 often decides according to actual design demand, and such as, on large touch panel, the thickness of sensing electrode layer 110 relatively just need design thicker in the demand meeting the resistance of lower line.Thus, this is by more obviously visual for the etching line making patterning sensing electrode layer 110 cause.In present embodiment, all configure optical compensating layer in sensing electrode layer 110 both sides, etching line can be made further not easily visible.
As aforementioned, in one or more embodiment of the utility model, the first optical compensation films 120 and the second optical compensation films 130 are arranged in pairs or groups and contact panel 100 forms optical match.After whole contact panel 100 receives an incident light, the first optical compensation films 120 is arranged in pairs or groups the second optical compensation films 130, can be in harmonious proportion incident light through each layer of contact panel 100 (as sensing electrode layer etc.) the tone of reflected light that formed.
