Zytronic integrates mechanical and touch controls

Zytronic, a specialist in custom-designed, durable Projected Capacitive Technology touch sensors has launched a Hybrid Touch technology, that fully integrates touch and physical controls into the sensor’s active area.

Zytronic’s hybrid touch allows tactile buttons or mechanical dials to be incorporated in and around the active area of the projected capacitive touchscreen and which are connected invisibly through the viewable area of the screen. It is the first time that the two most used control technologies in the world have been closely integrated in this way.

Zytronic designs and manufactures Hybrid Touch sensors with precisely machined apertures in the touch sensor located and shaped according to the system designers’ specifications, allowing their chosen dials or switches to be placed exactly where required. Zytronic then deposits power and data lines to the mechanical controls embedded within the touch interface using the same proprietary approach as it uses to deposit the touch electrodes, ensuring that they are invisible to the user of the system. These microfine traces are taken to a flex tail at the edge of the screen, where a connection can be implemented to the electromechanical controller. The system’s response to the mechanical control can be context sensitive – giving a very high degree of flexibility in user interface design.

Sensor electrodes in the screen are deposited around the physical holes required for the dial or the switches. Touches around the holes are processed by the touch controller in the usual way, but custom firmware in the controller is programmed to ignore the area of the holes themselves.

Hybrid Touch is available only on the new Zytronic ZXY500 family of touch controllers.
