In the unnecessary space binding switching FPC in cover plate both sides.
It is preferred that, in order to realize that master control touches hardware controls of the chip to cover plate button, the switching winding displacement passes through display
Main FPC and the touch chip of touch module link together.
A kind of novel touch screen button design method, it comprises the following steps：
Step 1, silk-screen button electric conduction routing formation coupled capacitor (can pass through silk-screen silver below the key area of cover plate
Slurry or other screen printing methods are realized), can be with flexible design, as long as required for meeting and using touch-control IC for the pattern of button
Sensing amount.
Step 2, the button of diverse location is connected to formation connecting interface at a fixed region by cabling (can set
It is set to binding interface or other class interfaces), it is convenient to be connected with master control touch chip.
Step 3, design switching FPC winding displacements, a connection keystroke interface, other end is connected to the touch chip on main FPC
In, touch chip can pass through mutual tolerance pattern or the touch-control from molar formula control button.
The beneficial effects of the invention are as follows：The novel touch screen button design method is reasonable in design, by the bottom of cover plate
The electric conduction routing of key corresponding table case is realized, design is simple, several buttons can be Independent keys and each cabling is formed separately
Independent keys；A cabling can also be shared as public cabling, and other cablings are independently formed separately composite-key, together
When to do insulation processing after the completion of the electric conduction routing and pattern of silk-screen to cover plate, GND is enclosed in design one, prevent outside ESD to by
The influence of key sensitivity, be not in during use button do not report the bad phenomenon such as a little, button touch-control excellent performance is adapted to batch
Production.
