Capacitive Touch

Projected Capacitive Type

It is the most attractive technology with Apple's iPhone touch, even though the patterned ITO is necessary, there is technological advantages such as soft touching and Multi touching.

Structure

Strength
  • Multi Touching.
  • Soft Touching(Zero Activation Force).
  • Protective Cover. -> Superior durability(60million times), No surface contamination.
Challenge
  • Sensitive to noise. -> Need to develop the noise reduction technology.
  • The difficulty to touch non conductive substance.
  • The demand for certain contact surface. (>Φ5)
Operation principle

It is the method calculated location of fingers as the change amount of Cap before and after, arranged sensing electrodes of X-axis and Y-axis by Matrix form.
