, will certainly increase the electric capacity between the first connecting portion 33 and the second connecting portion 53, if establish variation in thickness coefficient, be
, i.e. thickness after transparent insulating layer 4 changes
=
, if keep electric capacity constant, should reduce width
or length
, due to length
generally immutable, therefore ought to reduce width, the width after change
, guarantee electric capacity is constant.
When the narrowed width of connecting portion, because resistance value size is proportional to
, can make resistance value increase, simultaneously due to length
generally immutable, should increase the thickness of connecting portion, make the thickness of the junction after changing
, just can guarantee that resistance value is constant.The electric capacity of the connecting portion changing in order to ensure width and resistance characteristic, should meet: the cross-sectional area in the first connecting portion 33 and the second connecting portion 53 with thicker connecting portion is more than or equal to the cross-sectional area with thinner connecting portion.
As shown in Figure 4 and Figure 5, provided respectively and changed the first transparency conducting layer of front and back and the structural representation of the second transparency conducting layer, visible, in order to make the first pattern 31 with respect to the capacitance of the second pattern 51 and resistance value is uniform changes, transparent insulating layer 4 is with respect to becoming before thinner, the second transparency conducting layer 5 increases with the increase of second graph 51 thickness, but the width of the second connecting portion 53 reduces.As shown in Figure 6, provided the stereographic map of relative position place the first pattern and the second pattern in the capacitance type touch-control panel of invention, by the width of the junction that narrows down and the thickness of increase junction, in the situation that reduced the thickness of transparent insulating layer 4, the physical characteristics of whole capacitance type touch-control panel structure is not changed, both increase technology stability, reduced cost, guaranteed again normal use.
