SMK Develops Double-sided ITO Capacitive Touch Panel
Featuring No False Touch with Water Drop
and Support for Thick Cover Panel

   SMK Corporation has developed a capacitive touch panel consisting of double-sided ITO glass sensor “CapDuo Touch-2”, whose sensor patterns were improved from the conventional product “CapDuo Touch” to enable hybrid sensing (self-/mutual-capacitance), allowing touch detection even when a drop of water is on the panel, input when wearing gloves, and use with thick cover panel which is now in increasing demand.
   CapDuo Touch series features the single glass structure. As x and y sensors are formed respectively on the front and back surfaces of a single sheet of glass, it requires no OCA sheet for glass bonding, and contributes to narrower frame, thinner and lighter panel, and reduction of material costs compared to the “G1G” sensor consisting of two sheets of glass.
   Besides, the new product employs the bridgeless structure as with the conventional product and achieves superior appearance, contributing to the functional advancement of final products.

*ITO: indium tin oxide, OCA: optically clear adhesive
