Patent number: 11941211Abstract: In some examples, a touch screen can include touch electrodes that can function as drive (Tx) electrodes and sense (Rx) electrodes during a touch sensing operation of the electronic device. The drive electrodes can include +Tx electrodes and ?Tx electrodes that can receive drive signals that can have the same amplitude and frequency and opposite phases, for example. In some examples, the surface areas of the +Tx electrodes and the ?Tx electrodes can be the same and the distances of the +Tx electrodes and ?Tx electrodes from the Rx electrodes can be different. In some examples, the total charge coupled to a proximate or touching object can be zero, which can mitigate problems associated with ungrounded or poorly grounded objects in contact with the touch screen.Type: GrantFiled: March 17, 2023Date of Patent: March 26, 2024Assignee: Apple Inc.Inventors: William Matthew Pender Paul, Christoph H.

Patent number: 11790873Abstract: An electronic display may include a pixel circuit. The pixel circuit may include memory storage to store data values representative of image data to be depicted via the pixel circuit. The memory storage may also include memory components for storing bits of the data value. The pixel circuit may also include a light-emitting device for emitting light based at least in part on the data value and a controller. The controller may receive the data value and store the bits based on a mapping between the bits and the memory components. The mapping may be determined based on routing one or more of the bits associated with one or more defective memory components of the memory components to one or more other memory components of the memory components. The controller may also drive the light-emitting device to emit light based on the bits stored in accordance with the mapping.Type: GrantFiled: August 12, 2022Date of Patent: October 17, 2023Assignee: Apple Inc.Inventors: Stanley Bo-Ting Wang, Derek Keith Shaeffer, Ivan Knez, Jose Antonio Dominguez-Caballero, Tien-Chien Kuo
