Patent number: 9733745Abstract: A touch-sense device includes an overlay, such as a rough overlay or a compliant overlay, on a sensing layer. Use of the overlay changes a response of the sensing layer so that a light press is more distinguishable from a strong press by sensing electronics. Distinguishing the light press from the strong press enables the sensing electronics to report additional information in response to a press. In one example, a sensor signal of the sensing layer attains a first magnitude for a light press, and a second magnitude for a strong press, enabling the strong press to be distinguished. In another example, a sensor signal has a second edge in response to a strong press, and detection of the second edge enables the strong press to be distinguished. In various embodiments, a surface of the overlay has protrusions and/or cavities and/or is compressible.Type: GrantFiled: December 31, 2007Date of Patent: August 15, 2017Assignee: Cypress Semiconductor CorporationInventor: Victor Kremin
