Publication number: 20220312614Abstract: An electronic device may have transparent housing structures such as walls formed of glass or sapphire. Housing structures such as transparent housing structures may have a colored coating. The colored coating may include an absorptive layer and a metal layer.

Patent number: 10901543Abstract: Transparent conductors including a silver layer with high transparency and low sheet resistance are described. In some examples, the silver layer can be located between two transparent conductive oxide layers. The transparent conductor can further include additional transparent conductive oxide layers, optical layers, and/or additional conductive layers (e.g., layers including ITO or another fully or partially transparent conductive material), for example. In some examples, transparent conductors including a silver layer can be included in a touch screen device. For example, one or more shielding layers or one or more touch electrodes can include transparent conductors with a silver layer. In some examples, the silver layer can improve transparency, sheet resistance, and/or infrared reflection characteristics of the transparent conductor.Type: GrantFiled: September 27, 2018Date of Patent: January 26, 2021Assignee: Apple Inc.Inventors: Khadijeh Bayat, Isaac Wing-Tak Chan, Cheng Chen, Avery P.

Patent number: 10850666Abstract: A system such as a vehicle may have windows. A window may be provided with a light modular or other active layer having an electrically adjustable optical property. The active layer may have a pair of electrodes. The electrodes may be used to apply electric fields across the active layer to adjust the active layer. A lower sheet resistance electrode may be supplied with a current to ohmically heat the active layer. A higher sheet resistance electrode may be supplied with a voltage gradient to create a gradient in light transmission or other optical property as a function of distance across the higher sheet resistance electrode. The electrodes may be provided with terminals that are formed from elongated strips of metal or other terminal structures. The terminals may run along the peripheral edges of the electrodes.Type: GrantFiled: June 23, 2017Date of Patent: December 1, 2020Assignee: Apple Inc.Inventors: Martin Melcher, James R.

Patent number: 10845665Abstract: A window may be provided with a light modulator. The light modulator may be dynamically adjusted to control visible light transmission through the window. The window may also have layers that selectively block light with non-visible wavelengths. The light-blocking layers may block ultraviolet light, near infrared light such as light from solar radiation, and far infrared light such as heat produced due to the absorption of visible light by the light modulator. The light modulator may be a guest-host liquid crystal light modulator. The guest-host liquid crystal light modulator may have a layer of liquid crystal material with dye that is interposed between polymer substrate layers. The polymer substrate layers may be thermoplastic layers that are moldable to conform to window shapes with compound curves.Type: GrantFiled: October 17, 2016Date of Patent: November 24, 2020Assignee: Apple Inc.Inventors: Khadijeh Bayat, Cheng Chen, Ibuki Kamei, Shih-Wei Chang, Avery P.

Patent number: 10725228Abstract: An electronic device may generate content that is to be displayed on a display. The display may have an array of liquid crystal display pixels for displaying image frames of the content. The display may be operated in at least a normal viewing mode, a privacy mode, an outdoor viewing mode, and a power saving mode. The different view modes may exhibit different viewing angles. In one configuration, the display may include a backlight unit that generates a collimated light source and that includes a switchable diffuser film for selectively scattering the collimated light source depending on the current viewing mode of the display. In another configuration, the display may include a backlight unit that generates a scattered light source that includes a switchable microarray structure such as a switchable mirror structure or a tunable microlens array for selectively collimating the scattered light source depending on the current viewing mode.Type: GrantFiled: February 20, 2019Date of Patent: July 28, 2020Assignee: Apple Inc.Inventors: Hyungryul J.

Patent number: 10359480Abstract: Measuring a sample includes providing a magnetic field at the sample using an electromagnetic field resonator. The electromagnetic field resonator includes two or more resonant structures at least partially contained within dielectric material of a substrate, at least a first resonant structure configured to provide the magnetic field at the sample positioned in proximity to the first resonant structure. The sample is characterized by an electron spin resonance frequency.
