It is all the way sensing cabling, drive signal cabling and sensing cabling have some.Touch-screen used in the present invention and present city
The touch screen structure often used on face is consistent, simply with higher resolution, i.e., has on an equal amount of touch-screen more
X, Y cabling.But if relatively low to accuracy of detection requirement, it is also possible to directly use the touch-screen of low resolution.
The process of finger point touching screen, is to move closer to touch-screen until being contacted with touch-screen.When finger is near touch
When shielding certain distance, the electric capacity of touch-screen (cabling on touch-screen) and finger between takes place change, until finger is touched
When touching touch-screen, certain no longer changes to the electric capacity on (or multipair) XY lines on touch-screen.
When finger is when touch-screen is moved closer to, between the electric capacity and finger and touch-screen between finger and touch-screen away from
