Sensor:Detection method

It is designed to be mounted to the rear surface of a rigid transparent substrate (such as glass
or plastic), and operated by touching the front surface of that substrate.

It is an optically transparent touch sensor intended for use in front of an LCD (when mounted to
a suitable substrate).

It is a touch sensor incorporating an integrated rear projection surface intended for use with a
projector (No LCD required).

Application:

Primarily intended for use in large format interactive digital signage and information systems
found in applications such as retail, advertising and exhibitions.

OPERATION

The associated electronic controller effectively divides the sensor into pixel-sized sensing cells,
using an array of 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 the flexible film touch sensor is embedded within the sensor and
protected by the mounting substrate.

The driver software allows the touch screen 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.

The flexible film touch sensor are available with various surface preparations to facilitate bonding to the supporting substrate or window. Guidelines on the application these to a supporting substrate are available upon request.
