Publication number: 20190302926Abstract: A capacitive touch sensor wherein the touch sensitive panel has drive electrodes arranged on the lower side of a substrate and sense electrodes arranged on the upper side. The drive electrodes are shaped and dimensioned to substantially entirely cover the touch sensitive area with individual drive electrodes being separated from each other by small gaps, the gaps being so small as to be practically invisible. The near blanket coverage by the drive electrodes also serves to screen out interference from noise sources below the drive electrode layer, such as drive signals for an underlying display, thereby suppressing noise pick-up by the sense electrodes that are positioned above the drive electrodes.Type: ApplicationFiled: March 27, 2019Publication date: October 3, 2019Applicant: Neodrón LimitedInventors: Peter Sleeman, Samuel Brunet, Matthew Trend, Harald Philip

Patent number: 9612101Abstract: A two-dimensional capacitive touch sensor having a cover layer of varying thickness arranged on top of its electrode structure. An array of sensing nodes is formed between edge portions of the receiver electrodes and adjacent portions of the transmitter electrodes. To compensate for the varying thickness of the cover layer, the length of the edge portions per sensing node is varied to equalize node sensitivity across the sensor and thus suppress the systematic variation in node sensitivity which would otherwise arise as a result of the varying thickness of the cover layer.Type: GrantFiled: February 11, 2013Date of Patent: April 4, 2017Assignee: TouchNetix LimitedInventor: Peter Sleeman

Patent number: 9563317Abstract: A control panel for proximity and force sensing, includes a cover layer, a first electrode layer including a first force sensor electrode, a second force sensor electrode positioned in a second electrode layer or on a support layer, and a dielectric substrate at least a portion of which is compressible and is positioned between the first and second force sensor electrodes. The support layer is positioned to support at the vicinity of the second force sensor electrode support location so that compression of the dielectric substrate and the separation of the first and second force sensor electrodes depends on the magnitude of a force applied to the cover layer. Touch sensor electrodes are positioned on one or more of the electrode layers such that their capacitance depends on proximity of an object such as a finger. Controllers measure the capacitance of the force and touch sensor electrodes respectively and output force and touch proximity signals.Type: GrantFiled: May 15, 2014Date of Patent: February 7, 2017Assignee: Atmel CorporationInventors: Peter Sleeman, Samuel Brunet, Esat Yilmaz
