Description
Technical field
The present invention relates to the wiring of a kind of capacitance touch screen button, belong to contact panel manufacture technology field, refer in particular to the wiring in mutual tolerance formula capacitance touch screen Independent keys region.
Background technology
Touch-screen is as the most direct mode of human-computer exchange, and he does not need keyboard mechanical equipment, is more and more applied to every field in recent years, such as mobile phone, computer and media termination etc.Capacitive touch screen operation principle is, utilize induction electrode and drive electrode to intercouple formation node capacitor, the capacitance variations in this region is brought in finger touch screen region, and the variable quantity being calculated electric capacity by chip realizes touch function.But because each node capacitor is smaller, large about 0.1-8Pf, it is also relatively little that staff touches the capacitance variations brought, slightly outer signals interference or environmental change, the touch-screen key area of independent distribution as shown in Figure 1 will be made, often there are the phenomenons such as touch signal instability or mistaken touch, need software to adjust separately, reduce Consumer's Experience.
Therefore touching situation to improve touch key-press, needing a kind of new key area to connect up.
Summary of the invention
Technical purpose: the present invention is the wiring will announcing a kind of touch-screen key area, reduces the interference of outer signals, and improve push button signalling stability, software debugging is more prone to, and strengthens Consumer's Experience.
Technical scheme: the present invention discloses the wiring of a kind of touch-screen key area, comprises the steps:
Step one: complete the design of touch screen electrode pattern and the arrangement of Independent keys pattern;

Step 3: confirm that one or several drives passage to be connected with each button, the driving passage be connected with button can be public;
Step 4: the induction channels on adjacent for the induction channels be connected with key legend both sides is respectively drawn an induced signal line;
Step 5: the driving passage be connected with key legend is drawn a drive signal line respectively in button both sides;
Step 6: step 4 induction channels holding wire and step 5 driven channel signal line mutually to intersect containings, at button both sides formation coupling capacitance C
