Abstract:
1. An arrangement for detecting contact on a display, the arrangement comprising: a screen panel, an electrode forming part of a capacitor, and a support carrying the screen panel and being configured such that it the support structure is compressed by a compression force exerted by contact with the screen panel, the electrode being coupled with the screen panel, the capacitor having a capacitance that changes when the support is compressed, wherein the support comprises a base and an elastically deformable spacer arranged between the base and the screen panel such that a touch on the screen panel shifts the screen relative to the base; and wherein the electrode is a first electrode of the capacitor, wherein the first electrode is fixed to the screen panel and a second electrode is fixed to or formed by the base, and circuit means connected to the first and second electrodes for initiating an action on change of the capacitance.
