Background technology
Capacitance pen is exactly to complete man-machine right with conductive characteristic, for touch control capacitance formula screen using what conductor material made
The pen of operation is talked about, it is operated using the electric current sensing of human body.Capacitance type touch control screen is one piece of four layers of compound glass screen, glass
The inner surface and interlayer of glass screen respectively scribble one layer of ITO (both plating conductive glass), and outermost layer is the native glassivation of a thin layer silicon,
ITO coatings draw four electrodes as working face on four angles, internal layer ITO is screen layer to ensure good working environment.When
When finger is touched on the metal layer, because the formation of human body electric field, user and touch-control screen surfaces is with a coupled capacitor, for high frequency
For electric current, electric capacity is direct conductor, and then finger siphons away the electric current of a very little from contact point.This electric current is respectively from touch-control
Shield in the electrode on corner and flow out, and flow through the electric current of this four electrodes and be directly proportional to the distance of finger to corner, controller
By the accurate calculating to this four current ratios, the positional information of touch point is drawn.
Conventionally manufactured capacitance pen is moulded into after penholder using common ABS as raw material, machines by outer processing or certainly penholder table
Face is electroplated and spray painting two procedures, but it has the disadvantage that：(1) answered using the common ABS capacitance pen penholder techniques being made
