Specific implementation mode
To reach above-mentioned purpose and effect, the technological means and construction that the present invention uses, the just present invention that hereby draws are preferable
Its feature of embodiment elaborate and function are as follows, understand completely in order to sharp.
Please refer to shown in Fig. 3, Fig. 4 A and Fig. 4 B, for touch panel according to the present invention line construction preferred embodiment it
The B-B sectional views of stereogram, the A-A sectional views of Fig. 3 and Fig. 3.It can be clearly seen from the figure that a kind of touch panel of this creation it
Line construction is applied to include an one of circuit board 2 touch panel.So-called circuit board 2 is that electronic building brick and electronic circuit connect
The supplier connect, and so-called touch panel is can to receive the inputs such as contact (including human finger finger or stylus etc.)
The induction type display panel of signal.It further illustrates, such as present invention can apply to have silver paste to be coated with the capacitive films of demand
Sense (film sensor) touch panel.The circuit board 2 includes：One first induction channels 21 and one second induction channels 23.
First induction channels 21 its be set on the circuit board 2.First induction channels 21 penetrate one first connecting line
Road 22 is connected to a sensor 25, and in this present embodiment, which is embedded in the circuit board 2.Wherein, this
One connection line 22 is the good person of conductive effect, and the capacitance that the sensor 25 can be detected first induction channels 21
In the memory for noting down the sensor 25, and the capacitance detected is changed into capacitance charge and discharge by the calculation function through inside
The number of electricity, to judge the capacitance variations of touch panel.
Second induction channels 23 its be set on the circuit board 2.Second induction channels 23 penetrate one second connecting line
