Patent number: 10078402Abstract: 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.Type: GrantFiled: May 30, 2013Date of Patent: September 18, 2018Assignee: Zytronic Displays LimitedInventors: Andrew Morrison, Philip Andrew Rudland, Stephen Michael Ormston

Publication number: 20150109241Abstract: A method of producing a non-planar multi-touch sensing panel, said panel comprising a plurality of electrically isolated conductors crossing each other at a plurality of intersection points. The method comprises: forming the plurality of electrically isolated conductors by laying down insulated conducting wire on an adhesive layer, said insulated conducting wire comprising an insulating coating; forming a flexible conductor array sheet from the insulated conducting wires laid down on the adhesive layer, and laminating the flexible conductor array sheet onto a non-planar protective substrate thereby forming the non-planar multi-touch sensing panel.Type: ApplicationFiled: May 31, 2013Publication date: April 23, 2015Applicant: Zytronic Displays LimitedInventor: Andrew Morrison
