How it works
|
|
Once the panel is touched, there is
capacitance generated between finger, touch panel surface & ITO coating. When the
diamond pattern is scanned sequently, the capacitance of the diamond pattern underneath
the finger is the highest, other capacitance is proportional to the distance between
finger and touched area; the scanned diamond in X- coordinate will tell us which
diamond pattern the finger locates in, likewise in Y-coordinate the same operation
will detect the finger location, through the data obtained by scanning and weighted
calculation on X,Y coordinates we can figure out the accurate area touched on panel
