electronic control board • touch pad or touch screen: positioned over a screen LCD, TFT... • on glass using a transparent control panel printed by screen-print • high-tech design • vandalproof, antireflection, antiscratch • different shapes and sizes for the keys • single interface for displays and single keys CTK Capacitive Transparent Keyboard CTK is based on a very important physical principle: the charge variation of the capacitor. A special microchip loads the electric deviation field when a finger is closed to the key. The chance to adjust key sensibility makes this technology useful in a lot of fields. The most important innovation introduced by Battocchio is to apply this technology on a transparent control interface. Final result is a transparent flexible film. CTK is connected to the electronic board by a flat cable. This innovative keyboard is an excellent alternative to the touch screen thanks to the numerous advantages: CTK can be design for customer demands; shapes and sizes of the keys can be different; keys can be placed out of the display and backlighting is possible.
