Patent number: 11941214Abstract: Touch sensor panels/screens can include metal mesh touch electrodes and routing in the active area. In some examples, the touch sensor panel/screen can include row electrodes and column electrodes disposed over the active area of the display. In some examples, the routing traces for the row electrodes and/or column electrodes can be disposed in a border region and some of the routing traces for the row electrodes and/or column electrodes can be disposed in the active area. In some examples, some row electrodes can be shaved down to create an offset from the edge of the active area to accommodate routing traces in the active area. In some examples, the row electrodes can be formed in a first metal mesh layer and some routing traces in the active area can be formed in a second metal mesh layer, different from the first metal mesh layer.Type: GrantFiled: August 9, 2022Date of Patent: March 26, 2024Assignee: Apple Inc.Inventors: Ashray Vinayak Gogte, Christophe Blondin

Publication number: 20240077981Abstract: In some examples, a touch screen includes a first region corresponding to a region of the touch screen without touch electrodes; a second region corresponding to a region of the touch screen with a first conductive material (e.g., solid metal) with a first density in a first conductive layer; and a third region corresponding to a region of the touch screen with a second conductive material (e.g., metal mesh) with a second density, lower than the first density, in the first conductive layer. In some examples, the second region circumscribes the first region, and the third region circumscribes the second region. Some touch electrodes include a portion of the first conductive material in the second region and a portion of the second conductive material in the third region. Such touch electrodes can be routed using the first conductive material in the first conductive layer around the first region.Type: ApplicationFiled: August 30, 2023Publication date: March 7, 2024Inventors: Ashray Vinayak GOGTE, Yufei ZHAO, Christophe BLONDIN, Yoann J.

Patent number: 11836297Abstract: An input device includes a keycap, a first electrode disposed to move in response to movement of the keycap, a planar array of electrodes extending at least partially under the keycap, and a sensor. The planar array of electrodes includes a second electrode, a third electrode, and a fourth electrode extending between the second electrode and the third electrode. The sensor is coupled to at least one of the second electrode or the third electrode and configured to generate a signal indicative of a change in capacitive coupling between the second electrode and the third electrode. The change in the capacitive coupling may result from movement of the first electrode.Type: GrantFiled: March 22, 2021Date of Patent: December 5, 2023Assignee: Apple Inc.Inventors: John Stephen Smith, David S.

Publication number: 20230297199Abstract: Touch electrode architecture techniques can be used to reduce or eliminate metal mesh within the one or more high-transmittance regions of a touch screen including one or more high-transmittance regions. In some examples, one or more optical devices can be integrated with a touch screen such that light associated with the one or more optical devices passes through one or more layers of the touch screen. In some such examples, to avoid degrading performance of the optical devices, one or more high-transmittance regions can be used. Additionally or alternatively, in some examples, the high-transmittance can be achieved using touch electrode architecture techniques that use transparent or semi-transparent materials instead of opaque metal mesh within the high-transmittance regions.Type: ApplicationFiled: February 24, 2023Publication date: September 21, 2023Inventors: Christophe BLONDIN, Ashray Vinayak GOGTE, Ricardo A. PETERSON, Warren S. RIEUTORT-LOUIS, Yuchi CHE

Publication number: 20230284503Abstract: A display may have both a full pixel density region and a pixel removal region with a plurality of high-transmittance areas that overlap an optical sensor. Each high-transmittance area may be devoid of thin-film transistors and other display components. To improve transmission while maintaining satisfactory touch sensing performance, one or more segments of the touch sensor metal in the pixel removal region may have a reduced width relative to the touch sensor metal in the full pixel density region and/or one or more segments of the touch sensor metal in the pixel removal region may be omitted relative to the touch sensor metal in the full pixel density region. To mitigate a different appearance between the pixel removal region and the full pixel density region at off-axis viewing angles, the position of the touch sensor metal in the pixel removal region may be tuned.Type: ApplicationFiled: June 16, 2022Publication date: September 7, 2023Inventors: Ricardo A Peterson, Abbas Jamshidi Roudbari, Ashray Vinayak Gogte, Christophe Blondin, Sebastian Knitter, Warren S Rieutort-Louis, Yuchi Che, Yurii Morozov, Matthew D Hollands, Chuang Qian, Michael H Lim, Matthew J Schwendeman, Kenny Kim, Tsung-Ting Tsai, Yue Qu

Publication number: 20230168783Abstract: This relates to touch sensor panels/touch screens including touch electrodes in a bar-and-stripe pattern. The bar-and-stripe pattern can improve touch signal levels for touch detection and improve uniformity of touch signal as objects move across the touch sensor panel/touch screen. Touch electrodes in a bar-and-stripe pattern can be formed from metal mesh in one or more layers of metal mesh. In some examples, “stripes” can be formed from groups of touch electrode segments in a first layer of metal mesh and can be interconnected by bridges formed in a second layer of metal mesh, different from the first layer of metal mesh, in the active area of the touch screen. Multiple stripes can be interconnected in the border area and/or in the active area to form a row touch electrode. In some examples, “bars” may also include bridges in the second layer of metal mesh.Type: ApplicationFiled: January 13, 2023Publication date: June 1, 2023Inventors: Christophe BLONDIN, Xiaoqi ZHOU

Patent number: 11036341Abstract: A plurality of metallic components (e.g., conductive rods) can be included within an insulator layer of a touch sensor panel. The metallic components included within the insulator layer can be electrically floating. The metallic components can increase a signal coupling strength across the thickness of the insulator layer. In some examples, the metallic components can have a uniform spacing and uniform physical dimensions. In some examples, the metallic components can provide increased signal coupling in areas directly above touch sensitive regions of underlying touch sensor electrodes. In some examples, the metallic components can pass through the insulator in a straight line that is normal to opposing surfaces of the insulator layer. In some examples, the metallic components can be flared or otherwise pass through the insulator along a path that is not straight and/or not orthogonal to opposing surfaces of the insulator layer.Type: GrantFiled: September 20, 2019Date of Patent: June 15, 2021Assignee: Apple inc.Inventors: Alexandre Gourevitch, Christophe Blondin, Christopher J.
