A multi-touch touch panel and a method of detecting touches is disclosed. The touch panel comprises at least one hole in an active region of the touch panel, having a selected size for mechanically mounting a respective user input device.

Display arrangement

Apparatus and methods of providing power and/or data to devices at a touch panel are disclosed including a method of manufacturing a touch panel for a touchscreen, comprising the steps of: plotting at least one wire, on a layer of adhesive over a transparent substrate that comprises at least one through hole, in a predetermined pattern that comprises a first portion that extends over the substrate and a further portion that extends over a region of a transparent support that extends over at least a region of the through hole; providing touch electrodes for a touch panel of a touchscreen via the first portion of the plotted wire; and providing a plurality of electrical connectors for a user input device secured at the through hole, via the further portion of the plotted wire.

Button supply

Disclosed are a touch sensitive display and a method of operation thereof. The display comprises a sensor having an input put array of electrodes and, capacitively coupled thereto, an output array of electrodes and a controller operable to perform a scan operation at every intersection point of said input array. The scan operation comprises measuring a touch value for an intersection point; determining a proportional difference between said touch value and a base touch value for said intersection point as a proportion of said base touch value, wherein said base touch value is indicative of there being no touch event on the sensor; and comparing the proportional difference to a predetermined proportional touch threshold so as to determine whether there is a touch event at that point.
