Competitive Advantage:
Capacitive touch screen is a world popular trend for its highest
positioning and fast response,
the response time is shorter than resistive touch screen,
antistatic ability,save space,display is
the user interface and interface mode diversity,low
power,water-proof,fog-proof,design more
beautiful,specially on telephone and MID(mobile internet
device,such as tablet PC,iphone and
ipad), the touch panel is made of glass and film, also, it has good
transparent and has multi-points
touching.
Technical Principle:
Capacitive touch screen is a four-storey glass screen surface and
laminated within the glass screen is coated
with a layer of ITO, the outermost layer is a thin layer of silica
glass, laminated ITO coating as a face, four
electrode leads in the four corners, inner ITO good shielding to
ensure a good working environment. When
finger touch the metal layer that is, because the body farm, users
and touch-screen surface with a coupling
capacitor, high frequency current, capacitance is a direct
conductor, so fingers sucked away a very small
amount of current from the contact point. The respectively current
outflow from the touch electrode on the
four corners of the screen, and flows through the four electrode
current is proportional to the distance from
the fingers to the four corners, controller through the accurate
calculation of the four current percentage,
came to the location of the touch point.
