Unique Flexible Display with integrated QTC® Force Sensing Enables New Applications

Peratech, a world leader in 3D force-sensing technologies, continues to define the future of HMIs with the announcement of an active-matrix 3D force touch sensor that is integrated with a flexible OLCD, demonstrating how two disruptive technologies can work together to enable new applications.


LOPEC, Munich – 13 March 2018. Peratech, a world leader in 3D force-sensing technologies, continues to define the future of HMIs with the announcement of an active-matrix 3D force touch sensor that is integrated with a flexible OLCD, demonstrating how two disruptive technologies can work together to enable new applications.

The solution can be used to create flexible displays that incorporate multi-point force-touch sensing of arbitrary size, from wearable devices to large displays. The surface of the sensing display is flexible, allowing it to curve and conform to the shape of the end application, such as a wristband, dashboard or other work surface.

“This is a significant technological milestone for us,” said Jon Stark, Peratech CEO. “No other flexible active-matrix 3D touch sensor with integrated display is available on the market today. Our collaboration with Merck and FlexEnable has created a new enabling solution for human-machine interfaces to address existing demand.”

One key advantage is that Peratech’s QTC technology can eliminate false touches and open up a wide range of previously unsuccessful force-touch applications. These false touches, commonly associated with capacitive touch sensing, have limited the adoption of touch for safety critical uses including medical, industrial and automotive applications.

The integrated solution is based on FlexEnable’s low-temperature organic thin-film transistor (OTFT) fabrication expertise using Merck lisicon® OTFT material technology together with Merck  licristal® liquid crystal materials. All of the circuitry that drives the organic LCD is integrated alongside the 3D touch sensing elements, making display and force touch a single component in terms of design and system integration.  This application will be introduced at LOPEC 2018 in Munich, Germany.  Visitors can discover and experience this technology at the Merck booth.

The result is a high-resolution force-sensing display. The force sensor provides a raw spatial resolution of 25ppi using 100 by 64 active-matrix sensing elements for the 3D touch sensor. The elements, or sensels, detect both location of touch points and the amount of force applied to each sensel in the contact area, making the theoretical interpolated resolution greater than 10,000 ppi with standard ICs typically used in consumer, automotive, and industrial electronics.

About Peratech

Based on patented Quantum Tunnelling Composite (QTC®) technology, Peratech’s force sensors bring a new dimension to tactile or force-touch controls by being able to sense force from under 10 grams to over 10 kilograms in a sensor as thin as 50 microns. QTC-based sensors are very robust and resilient, so that changes in resistance due to even the slightest pressure are both predictable and repeatable over millions of cycles.

Combined with Peratech embedded software, QTC technology offers human machine interfaces (HMI) designers unrivalled creative freedom to expand and differentiate user experiences with a tested, mass-producible assembly. Peratech’s award-winning, thin and flexible QTC sensors come in single-point, 3D single-touch, and 3D multi-touch versions. They can be used above, below or around rigid or flexible displays, or under metal, plastic, wood, or glass surfaces. The QTC touch experience is intuitive, consistent, precise, durable and reliable, whatever the environment, even when using gloved fingers or in the presence of moisture.

The diverse applications for QTC force sensors include consumer and automotive electronics, smart home systems and appliances, and industrial controls. Over a million devices around the world now employ the technology. Peratech’s custom design and integration service minimises both cost and time-to-market. The company also offers a range of standard products. Peratech Holdco Ltd. is a privately held company based in Richmond, North Yorkshire, UK.
