Publication number: 20230011279Abstract: A touch sensor panel includes a first set of touch electrodes configured to operate as drive lines and that are disposed in a first layer of the touch sensor panel. The touch sensor panel also includes a second set of touch electrodes configured to operate as sense lines and that are disposed in a second layer of the touch sensor panel, different than the first layer of the touch sensor panel, such that one or more mutual capacitance touch nodes are formed by the first set of touch electrodes and the second set of touch electrodes. The touch sensor panel also includes a third set of touch electrodes configured to operate as self-capacitance electrodes and that are disposed in the first layer or the second layer of the touch sensor panel.Type: ApplicationFiled: May 26, 2022Publication date: January 12, 2023Inventors: Christophe BLONDIN, Jean-Marie BUSSAT, Robert Leo SHERIDAN, Sagar Rajiv VAZE

Patent number: 10936135Abstract: A touch sensor panel is disclosed. In some examples, the touch sensor panel comprises a first layer including a plurality of drive lines including drive electrodes, wherein the drive lines are configured to be coupled to drive circuitry during touch sensing on the touch sensor panel. In some examples, the first layer includes a plurality of sense lines including sense electrodes, wherein the sense lines are configured to be coupled to sense circuitry during the touch sensing on the touch sensor panel. In some examples, the first layer includes a plurality of first shielding electrodes, wherein the first shielding electrodes are disposed between the drive electrodes and the sense electrodes. In some examples, the touch sensor panel comprises a second layer, different than the first layer, including one or more bridges electrically coupling at least two of the first shielding electrodes together.Type: GrantFiled: July 1, 2019Date of Patent: March 2, 2021Assignee: Apple Inc.Inventors: Alexandre Gourevitch, Christophe Blondin, Ashray Vinayak Gogte, Xiaoqi Zhou, Vipul Chawla, Robert Leo Sheridan

Patent number: 10599247Abstract: Thermal compensation can be applied to force measurements of a force-sensitive button. A temperature differential between an object and the force-sensitive button can result in changes in the reconstructed force by the force sensor due to thermal effects rather than actual user force, which in turn can result in degraded performance of the force sensor (e.g., false positive or inconsistent activation force). In some examples, a force-sensitive button can include a force sensor configured to measure an amount of force applied to the force-sensitive button, and a temperature sensor configured to measure a temperature associated with the force sensor. The measured temperature can be used to compensate the amount of force measured by the force sensor based on the temperature associated with the force sensor. In some examples, the thermal compensation can be applied when an object is detected contacting the force-sensitive button (i.e., when rapid temperature differentials can occur).Type: GrantFiled: September 6, 2016Date of Patent: March 24, 2020Assignee: Apple Inc.Inventors: Eric S. Winokur, Robert Leo Sheridan, Leah M. Gum, Sora Kim, Giovanni Gozzini
