FOCALTECH
Touch controllers, display drivers and HMI ICs
About the manufacturer
FocalTech Systems is a semiconductor company specializing in integrated circuits for human-machine interfaces. The manufacturer develops capacitive touch controllers, display-driver ICs, integrated touch-and-display solutions and fingerprint-recognition devices. Its technologies are designed for products in which the display and touch surface form a central part of the user interface, from compact consumer devices to industrial and automotive panels.
The company supports different touch-panel architectures, including conventional capacitive structures as well as on-cell and in-cell implementations. This allows controller selection to be adapted to panel size, sensor geometry and the construction of the complete display stack. In addition to detecting touch points, modern controllers must manage electrical noise, cover-glass thickness, edge behavior, gesture recognition and the interaction between the sensor and display electronics.
FocalTech solutions are therefore relevant to smartphones, tablets, touchpads, appliances, industrial terminals, automotive displays and other HMI systems. Successful integration depends on matching the controller to the sensor topology, channel count and panel dimensions while also considering host interface, firmware configuration, ESD robustness and EMC performance. In demanding designs, display noise and charger interference can be as important as the nominal number of supported touch points.
Applications
FocalTech ICs are used in products where the touchscreen is a primary element of the user interface.
