Force Sensing Enables True Edge-to-Edge Mobile Displays


Peratech claims to define the future of Human Machine Interfaces (HMIs) with its latest demonstration that shows how Quantum Tunnelling Composite (QTC) force sensing can accelerate the evolution of mobile phones. The latest trend within mobile handset design is to extend the screen to the very edge of the case, even curving around to the side, to maximize the useable display area. While technologies like flexible OLED displays can support this, it presents challenges for designers who need to incorporate legacy features such as the home button into ever-smaller spaces.


QTC technology enables a home button based on force sensing to be fully integrated below the glass screen of the phone, without the need for a bezel of any kind. This provides a viable solution for including a home button that offers users a positive force action, but without taking up any of the phone’s displayable area.  Capacitive sensing alone is unable to deliver the realistic home button experience and is also prone to false triggering. Combining capacitive and force sensing eliminates false triggering and supports unique design paradigms such as the finger print sensor becoming the power button. For more info, visit Peratech.
