Zyfilm/Zyprofilm
ZYFILM® and ZYPROFILM® are flexible film touch panels incorporating ZYTRONIC’s patented projected capacitive technology (PCT™). The touch panels are designed to be mounted to the rear surface of a rigid transparent substrate (such as glass or plastic), and operated by touching the substrates front surface

Operation
The associated electronic controller effectively divides the sensor into pixel-sized sensing cells, using an array of embedded microfine metal track electrodes, which are not ITO (Indium Tin Oxide) based, and are virtually invisible when in front of a powered display or rear projection film. These tracks are connected to the electronic controller board, and an oscillation frequency is established for each track. Using the theory of capacitance field effect, a touch on the overlay substrate to which the sensor is mounted causes a change in the oscillating frequency of the tracks around that particular point; the position of which is then determined by the driver software. Unlike conventional capacitive systems where the operator touches the actual conducting surface of the sensor, the active component of ZYFILM® / ZYPROFILM® is embedded within the sensor panel and protected by the mounting substrate.
The driver software allows the touch sensor panel to interface with the host computer’s operating system by emulating the behavior of a computer mouse, and translates touches into mouse movements and clicks.
ZYFILM®and ZYPROFILM® are available with various surface preparations to facilitate bonding to the supporting substrate or window.
