It asks, transparency conducting layer 12 has a conductive pattern.For example, by appropriate circuit design or layout, transparency conducting layer 12
Conductive pattern may make up the part of projecting type capacitor touch-control module, make the transparent conductive film 10 of the present invention can be used as a touch-control
Film.It is understood that the line impedence of transparency conducting layer 12 is smaller, the reaction time of touch-control film is shorter or applied to larger
The display module of size.
Fig. 3 is refer to, in an embodiment, transparent conductive film of the invention further includes an optical interference layer 13.Optics is done
Layer 13 is related to be arranged between transparent substrate 11 and transparency conducting layer 12.It is understood that the electrically conducting transparent not being patterned
The position of 12 covering of layer exposes optical interference layer 13.According to this structure, transparent conductive film of the invention is in reflection exterior light
During line L1, L2, although generating optical path difference due to the difference in height of transparency conducting layer 12, optical interference layer 13 can compensate for light L2's
Influence caused by optical path difference, and then reduce aberration phenomenon.Therefore, in embodiment shown in Fig. 3, electrically conducting transparent of the invention
