The solution can be used to create a flexible display that enables multi-touch force sensing of any size from a wearable device to a large display. The surface of the sensing display is very flexible and can be based on end applications such as wristbands, dashboards, or other work surfaces The shape of the device is bent. According to Peratech, its QTC technology eliminates the common mis-touch of capacitive touch sensing.
Peratech CEO Jon Stark stated that Peratech has collaborated with Merck and FlexEnable to create a new groundbreaking solution for human-machine interface. The integrated solution is based on FlexEnable's low-temperature organic thin-film transistor (OTFT) fabrication technology, which uses Merck lisicon® OTFT material technology and Merck licristal® liquid crystal materials. All circuits that drive OLCDs are integrated with 3D touch sensor elements, making display and force sensing a single component in design and system integration.
The display that can be realized with this integrated solution is a high-resolution force-sensitive display. The force sensor uses a 100×64 active-matrix sensing element to provide an initial spatial resolution of 25 ppi for a 3D touch sensor. These elements or sensors can detect The position of the contacts and the magnitude of the force applied to each sensor in the contact area, using standard ICs commonly used in consumer, automotive and industrial electronics, allows the theoretical interpolation resolution to be greater than 10,000 ppi.
