Patent number: 10139294Abstract: One or more strain sensors can be included in an electronic device. Each strain sensor includes a strain sensitive element and one or more strain signal lines connected directly to the strain sensitive element. The strain sensor(s) are used to detect a force that is applied to the electronic device, to a component in the electronic device, and/or to an input region or surface of the electronic device. A strain sensitive element is formed or processed to have a first gauge factor and the strain signal line(s) is formed or processed to have a different second gauge factor. Additionally or alternatively, a strain sensitive element is formed or processed to have a first conductance and the strain signal line(s) is formed or processed to have a different second conductance.Type: GrantFiled: March 13, 2017Date of Patent: November 27, 2018Assignee: Apple Inc.Inventors: Michael Vosgueritchian, John Stephen Smith, Sinan Filiz, James E.

Patent number: 9964820Abstract: A display may have a thin-film transistor layer and a color filter layer. The display may include light blocking structures formed on a transparent substrate. In one arrangement, a clear planarization layer may be formed over the light blocking structures. The thin-film transistor layer may be formed over the planarization layer. The color filter layer may be integrated with the thin-film transistor layer. At least light blocking structures and the planarization layer should be formed from high temperature resistance material. In another arrangement, the color filter layer may be formed on the light blocking structures. A clear planarization layer may then be formed over the color filter layer. The thin-film transistor layer may be formed on the planarization layer. In this arrangement, the color filter layer also needs to be formed from thermal resistance material.Type: GrantFiled: September 19, 2014Date of Patent: May 8, 2018Assignee: Apple Inc.Inventors: Byung Duk Yang, Kyung-Wook Kim, Shih-Chang Chang, Hiroshi Osawa, John Z.
