Capacitive Touch Screen PCAP Technology
Capacitive PCAP 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. A lot of current mobile devices such as smartphones or tablets was using capacitive touch screen film as its monitor.
体温、ユーザー、タッチスクリーンの表面にカップリングコンデンサ、高周波電流、静電容量が直接導体であるため、指が金属層に触れると、指は接点から非常に少量の電流を吸い取ります。 画面の四隅にあるタッチ電極からのそれぞれの電流の流出は、四つの電極電流を流れ、指から四隅までの距離に比例し、コントローラーは4つの電流割合の正確な計算して、タッチでの座標値を取得します。


静電容量式タッチスクリーンのメリット
Greentouch‘s 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.
