An apparatus for sensing a physical attribute is shown, that includes a first track () defining a first electrode on a substrate (), a second track () defining a second electrode on said substrate and an active film () in cooperation with a first sensor portion () of the first electrode and a second sensor portion () of the second electrode. The second electrode includes a first extended portion () to establish a first additional resistance not cooperating with the active film.

Sensing physical attributes

Pressure sensitive sensors are integrated with light emitting picture elements (to). Light-emitting picture elements (to) are arranged upon a substrate (), such that located light-emitting picture elements are surrounded by a black matrix () of non-light-emitting regions. A sensor matrix of pressure sensitive sensor elements (to) is located at regions of the black matrix, such that sensor elements are aligned at positions over the black matrix and do not occlude the light-emitting picture elements.

Integrating pressure sensitive sensors with light emitting picture elements

An apparatus for detecting a mechanical interaction has a plurality of scan lines and a plurality of output lines. An intersection between each scan line and output line provides a connection to a plurality of sensing elements. Each of the sensing elements comprises a variable resistance element and a voltage amplifier. The apparatus includes an output processor which determines a voltage output in parallel at each output line from the plurality of sensing elements on activation of one of the scan lines from a driving processor.

Detection apparatus

Illumination functionality is combined with a touch-sensing functionality. A first electrical conductor and a second electrical conductor are located on a substrate. A pressure-sensitive element () is connected across the conductors and a light-emitting device () is also connected between the conductors. A control circuit alternates between energizing the pressure-sensitive element with current flowing in a first direction and driving the light-emitting device with current flowing in an opposite direction.
