Master Touch 21.5 Inch Multi Touch WD8752 Controller IC GFF Touch Panel
1. Product Description
Master Touch 21.5 inch GFF projected capacitive touch screen panel, via a process of sputtering an ITO pattern on a film substrate to make a film-sensor, perceive touch accurately through capacitance coupling.
Capacitive touch panel works through body's current induction.When finger is on or close to touch panel surface,due to body electric field, the user and touch panel surface forms one coupling capacitance. For high frequency current, capacitance is direct conductor, then fingers suck a small current from the contact point, through amplifying and accurately calculating this current signal, the controller works out the touch point position.
The advantages of 21.5 inch GFF are low capital cost, suitable for small quantity batch production, and light structure.
