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.
