Consult Fig. 7, then, substrate 1 with bridge layer 31 form an insulation course 6, and this insulation course 6 is cover by entire surface on substrate 1 and each bridge layer 31.In the present embodiment, this insulation course 6 mainly made by pi, and utilizes the mode of spin coating to be formed at substrate 1 surface.But in different enforcement aspects, the material of insulation course 6 and production method can optionally adjust, and are not limited with the content disclosed herein.
Consult Fig. 8, subsequently, on each bridge layer 31, form four buffer structures 33 and an insulation system 32 by same patterning Composition.Buffer structure 33 cover part bridge layer 31, and extend to substrate 1 by the sidewall of bridge layer 31 and form a slope 331.The end face that slope 331 extends to lower substrate 1 for buffer structure 33 by the end face of higher bridge layer 31 specifically forms, and therefore forms the highly gradient structure between bridge layer 31 and substrate 1.And this patterning Composition system comprises the steps such as micro-shadow, etching, therefore can produce the structure of buffer structure 33 and insulation system 32 simultaneously.But in different enforcement aspects, buffer structure 33, insulation system 32 also can make by fabrography, and are not limited with the enforcement aspect of Fig. 7, Fig. 8.
Consult Fig. 9, then come, substrate 1, bridge layer 31, insulation system 32 and buffer structure 33 form a transparency conducting layer 7 by coating techniques such as sputters, and this transparency conducting layer 7 is mainly made up of transparent conductive materials such as such as tin indium oxides.
Consult Fig. 1 and 10, finally, utilize micro-shadow and etch process to carry out patterned process to transparency conducting layer 7, and obtained first touch control electrode 41 and the second touch control electrode 42.First touch control electrode 41 is partly overlapped in bridge layer 31 respectively, and covers the slope 331 of buffer structure 33.Second touch control electrode 42 is arranged on substrate 1, and extends overlapped on each insulation system 32 respectively, and makes the second touch control electrode 42 not contact bridge layer 31 by insulation system 32, and then the first touch control electrode 41 and the second touch control electrode 42 are electrically insulated each other.And in the process of plating transparency conducting layer 7 (see Fig. 9), because transparency conducting layer 7 can extend on bridge layer 31 by substrate 1 by the slope 331 of buffer structure 33, thus avoid follow-up the first touch control electrode 41 defined at the regional fracture being extended upwardly to bridge layer 31 by substrate 1.
In sum, the slope 331 through buffer structure 33 avoids the first touch control electrode 41 at the regional fracture being extended upwardly to bridge layer 31 by substrate 1, therefore really can reach the purpose of this utility model.
Only as described above, be only embodiment of the present utility model, when can not limit the scope of the utility model enforcement with this, namely the simple equivalence change generally done according to the utility model claim and patent specification content with modify, all still belong in scope that the utility model patent contains.
