Touchscreen & firmware tuning

We can help select the optimum touchscreen technology for your application as well as customise it to ensure best performance in various use, including gloved touch and water rejection.

Get in touch

An industrial touchscreen as good as your smartphone

A touchscreen is made up of 3 basic elements, a sensor, a controller and a software driver. Whether you want Projective Capacitive, single or multi-touch,  different touchscreen technology has its own benefits and limitations. All touchscreen firmware can be optimised to meet the most challenging environments.

Touch IC selection

Choosing the right touch controller IC is crucial for optimal touch performance and must be tailored to each customer's specific product application. We can help you select the best touch controller IC, including the latest industrial-grade options with glove input and anti-noise capabilities.

The key factors we will take into account when helping you select the right touch IC include:

  • Input type
  • Environment
  • Display size
  • Coverlens material and thickness
  • Electromagnetic compatibility (EMC)

Firmware Tuning 

The firmware of the selected controller IC can be adjusted by our engineers to ensure the touchscreen delivers the best performance for its intended application.

  • Specific cover lens materials and thicknesses
  • Gloved finger inputs of various material types
  • Rejecting false touches caused by water droplets
  • Improved immunity to EMI through software filtering

Types of Touchscreen Technology

Projected Capacitive

PCAP touchscreens can can detect multiple points of contacts and can also be operated while wearing certain types of gloves. They are more responsive than a resistive screen when it comes to gestures such as swiping and pinching.

What is PCAP Touch?

Resistive

Resistive touchscreens are lower cost that capacitive touch screen but have just single-point input. Ideal for kiosk applications.

What is Resistive Touch?

Optical Positioning

Using optical sensors at the top of the screen and IR LEDs on the other sides, light emitted from the LED is reflected back to the imaging sensors and when the light beam is broken by a touch a touch is registered.
