  • Publication number: 20180052546
    Abstract: 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.

  • Patent number: 9612101
    Abstract: 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.

  • Patent number: 9563317
    Abstract: 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.

  • Patent number: 8937611
    Abstract: A touch data set is acquired via signals from each sensing node in a capacitive sensor array having a plurality of sensing nodes. Touch presence and location on the capacitive sensor array is determined from the touch data set. In subsequent sampling periods while presence of a touch continues to be detected, touch data sets may be acquired from respective subsets of the sensing nodes, each subset being located at and adjacent to the touch location determined in the preceding sampling period.

  • Patent number: 8830180
    Abstract: A capacitive position sensor has a two-layer electrode structure. Drive electrodes extending in a first direction on a first plane on one side of a substrate. Sense electrodes extend in a second direction on a second plane on the other side of the substrate so that the sense electrodes cross the drive electrodes at a plurality of intersections which collectively form a position sensing array. The sense electrodes are provided with branches extending in the first direction part of the way towards each adjacent sense electrode so that end portions of the branches of adjacent sense electrodes co-extend with each other in the first direction separated by a distance sufficiently small that capacitive coupling to the drive electrode adjacent to the co-extending portion is reduced. Providing sense electrode branches allow a sensor to be made which has a greater extent in the first direction for a given number of sense channels, since the co-extending portions provide an interpolating effect.

  • Patent number: 8736568
    Abstract: In a touch sensor, as well as providing touch position data, additional data is provided on the shape of the touch. This is achieved by having sampling nodes on a finer mesh than the size of the actuating object, typically a finger, so each finger touch activates a group of adjacent nodes on the sensor. In this way, each touch has a shape formed by the activated nodes. The shape allows the touch sensor to report an angle with each touch and data indicating how elongate the touch is, preferably both together as a vector in which the direction of the vector gives the angle and the magnitude of the vector gives the ellipticity. For each frame of data collected from the sensor array, the sensor outputs an (x, y) coordinate of touch position and a further (x, y) coordinate of a shape vector.
