  • Clicktouch standard industrial projected capacitive touchscreens designed for  “harsh” environment (Industrial, Medical applications) supporting thick overlay, water and glove operations available:
    • For most common industrial LCD models in 3.5”, 4.3”, 5.7”,  7”,  8.5”, 10.4”, 12.1” and 15” (these will be further expanded)
    • For full customized design
    • Support multi-gesture detection
    • 2 technologies: self capacitance and mutual capacitance
  • Clicktouch controller
    • Based on Cypress TrueTouch® Touchscreen controllers
    • Chip on tail / Chip on PCB



 The Clicktouch Standard Solution is a complete working package with the following items:

  1. Overlay
    Glass, PMMA, Polycarbonate
    Can be supplied by customer or by Clicktouch
    Lamination can be performed by Clicktouch
  2. ITO-layer
    Standard ITO-Foils by Clicktouch are from 3.5” to 15”
    (See above)
  3. Clicktouch-controller
    Clicktouch controller based on Cypress PSoC®
    HEX-file to program the chip
    Chip on tail / chip on board
    Self capacitance and mutual capacitance
    I2C and USB
  4. LCD
    Integration of LCD can be done by Clicktouch

Clicktouch delivers you a total solution, which means a guaranteed and proved solution. There’s also a possibility to integrate our touchscreen in your carrier plate. Clicktouch is taking care of all these items: Overlay, lamination, ITO-foil, Clicktouch-Controller, Firmware (Hex-file), and will assure the working with your LCD and housing! The biggest advantage of this solution is the user-friendliness.

All these items could also be bought separated and could even be updated to the demands of the customer



  Cypress Value  

Flexible single chip controller ideal as technology platform both for Capacitive Sensor and Project Capacitive ITO sensor scalable from low (3”) up to mid (10”) diagonal screen (leveraging the large I/O pin count).

Integrated USB and I2C interface option make it versatile for embedded and embedded PC applications.

Availability for the full swing (5V / Vcc) capsense voltage range makes the design very robust.

Optimal SNR enables tick overlay (up to 6mm glass) support widely needed for industrial, medical and automotive applications.

Integrated IDAC availability allows the implementation of several design features like self calibration (system auto tuning) for easy system tuning to design changes, production tolerances and variances. The same enables a dynamic finger threshold providing an equalized user experience to different finger sizes while providing glove operation support.

The PSoC flexibility did allow for a CapSense-like user design approach for Force sensor creating an homogenous design environment for all sensor solutions.

Key functions of Cypress chip:

  • Host communication using I2C, USB, SPI…
  • Scanning of the sensor and processing of the raw data
  • Auto tuning and auto threshold calculation
  • Generating interrupts for host
  • Adjustment possible of default parameters stored in flash for customer tuning
