TCI-News Abonieren

Capacitive technology offers durability, reliability, and optical clarity. Popular applications include gaming machines, ATM installations, kiosks, industrial equipment, and point-of-sale.

Capacitive touch screens are curved or flat glass substrates coated with a transparent metal oxide. A voltage is applied to the corners of the overlay creating a minute uniform electric field. A bare finger draws current from each corner of the electronic field, creating a voltage drop that is measured to determine touch location.

 

Advantages

  • very accurate
  • good optical clarity
  • good resolution

Disadvantage

  • needs bare finger or capacitive stylus
    (that meens: no using with gloves)
