PCAP touch solutions for every application

Projective capacitive touches are basically available in two different structures. First, there are sensors based on PET films. These are flexible and can be laminated to the cover glass (OCA film). On the other hand, there are glass sensors, which are usually based on a rigid glass substrate and thus joined by liquid glue, means optical bonding (OCR), with the cover glass.

Whether standard PCAP sensors or individual requirements – we are your partner

  • Foil sensors are based on the controller platform EETI and ILITEK
  • PCap standard sensors & custom designs from 3 “to 75” possible
  • Structure of the PCap sensors based on ITO (up to 31 “) as well as Silvernanowire (from 31”)
  • High quality standard incl. the latest machines in sensor production in Taiwan and Korea
  • Maximum signal-to-noise ratio (SNR), indicator for a good PCap system, is possible
  • Low resistance values ​​of the electrodes on the sensor of 60 <= ohms / sq. <= 100 (at Silvernanowire 20-60)
  • Good price / performance ratio of the film sensors
  • Attractive process costs due to processing in the lamination process
  • Complete firmware support
    Multitouch
    Glove operation
    Hide of water, salt water, blood
    Handball recognition
    Pen input active, passive
  • Special designs possible:
    Very thick cover glass (> = 6 mm)
    Sensor area larger than TFT module to operate Keys / Slider / Wheels
    Force Touch -> PCap technology combined with pressure-sensitive functionality
    Various formats like “Stretched Design”
  • Interfaces I²C, USB, UART implemented as COF (Chip-on-Tail) and COB (Chip-on-Board)
  • D-ITO glass sensors based on the ATMEL controller platform with very low resistance values ​​for mission-critical applications
  • Glass sensors are joined gently by optical bonding with the cover glass
