Projected Capacitive Touch Screen Solutions

Projected Capacitive touch screen technology works off of an electrostatic field that is created by layers of conductive materials that are individually etched to form a grid pattern of electrodes. A touch event occurs when a finger or conductive stylus interferes with the electric field projected above the surface. This change in capacitance is detected by the controller which determines the X and Y coordinates of the touch. Multiple fingers can be tracked simultaneously and reported to the operating system for gesture recogniztion.

The quickest way to get started with Projected Capacitive Touch is to order one of our standard Double-Sided-ITO-Glass (DITO) sensors with either a Microchip or EETI touch controller directly from our web site. We also have standard Open Frame Products that can also be ordered directly from our web site. The Open Frame Products include include a USB touch controller, an LCD, and an LCD driver board with HDMI and VGA inputs. Our standard products are great for proof-of-concept designs, software development, technology evaluation, and even small production runs.

All of our Projected Capacitive Touch solutions include:

  • Multi Touch Functionality
    • 4, 10, or 16 touches depending on the controller
  • Multi Touch Gesturing
    • Typically the operating system recevies the touch data and performs gesture recognition
    • Some of our controllers include gesture detection and reporting for drag, pinch, zoom, and rotate
  • ≥ 9H Surface Hardness
  • Accurate and Reliable 
    • Auto calibrates with no user input on power up
    • Monitors and corrects for touches that are present during power up
    • Constantly updates calibration to compensate for environmental changes
    • Dynamic noise avoidance and filtering
  • Enhanced Sensitivity
    • Effortless input with finger
    • Standard glove detection on all controllers
    • Dynamic glove detection on some controllers
    • Passive stylus detection (depends on size of stylus and electrode pitch of sensor)
  • Multiple Control Board Options
    • Communications through USB or I2C
    • Printed Circuit Board (PCB) or Chip On Flex (COF) form factors
  • Full Customization
    • Custom sizes
    • Custom tail lengths and locations
    • Custom cover len materials, films, and coatings
    • Custom cover lens decoration
    • Custom PCB or COF circuits
    • Custom integrated PCAP buttons
    • Custom LCD and driver board designs and integration
