The breach 420a of one electrode wires 420 forms a zigzag respectively with its corresponding electronic pads 430
(jagged) structure.Here, the laciniation that formed of the breach 420a of the first electrode wires 420 with
The laciniation that corresponding electronic pads 430 is formed is arranged opposite.
Additionally, the laciniation that formed of the breach 420a of the first electrode wires 420 and electronic pads 430
Laciniation be to be made up of multiple triangle patterns.In the present embodiment, the sawtooth of electronic pads 430
Shape structure is made up of two triangle patterns 432, and these two triangle patterns 432 share one article
Two connecting lines 450, but the present invention is not limiting as constituting the quantity of the triangle pattern 432 of laciniation.
It addition, as plotted as shown in Figure 4, in the present embodiment, each triangle pattern 432 of electronic pads 430
All it is in corresponding jagged breach 420a.Similarly, above-mentioned design mode can increase
Add the capacitance between each first electrode wires 420 and corresponding electronic pads 430, promote contact panel 400
Operational Figure Of Merit.
In sum, the contact panel of the present invention utilizes the bridge circuit of flexible circuit board by corresponding second
Connecting line connects, and can simplify the processing procedure of contact panel, improves and produces yield, and and reduces contact panel
Frame size.Additionally, in the design of the contact panel of the present invention, each electronic pads is arranged in
In the breach of the most each first electrode wires, can increase and couple electric capacity between the first electrode wires and electronic pads
Value, promotes the Operational Figure Of Merit of contact panel.
Although the present invention is open as above with embodiment, so it is not limited to the present invention, this area skill
Art personnel without departing from the spirit and scope of the present invention, when making a little change and retouching, thus this
Bright protection domain is when being as the criterion depending on the defined person of appended claims.
