Patent number: 10748969Abstract: A display may have an array of pixels. Each pixel may have a light-emitting diode such as an organic light-emitting diode or may be formed from other pixel structures such as liquid crystal display pixel structures. The pixels may emit light such as red, green, and blue light. An angle-of-view adjustment layer may overlap the array of pixels. During operation, light from the pixels passes through the angle-of-view adjustment layer to a user. The viewing angle for the user is enhanced as the angular spread of the emitted light from the pixels is enhanced by the angle-of-view adjustment layer. The angle-of-view adjustment layer may be formed from holographic structures recorded by applying laser beams to a photosensitive layer or may be formed from a metasurface that is created by patterning nanostructures on the display using printing, photolithography, or other patterning techniques.Type: GrantFiled: November 10, 2017Date of Patent: August 18, 2020Assignee: Apple Inc.Inventors: Jean-Jacques P.

Patent number: 10591774Abstract: A display may have display layers that form an array of pixels. The display layers may include a first layer that includes a light-blocking matrix and a second layer that overlaps the first layer. The first layer may include quantum dot elements formed in openings in the light-blocking matrix. The light-blocking matrix may be formed from a reflective material such as metal. The second layer may include color filter elements that overlap corresponding quantum dot elements in the first layer. Substrate layers may be used to support the first and second layers and to support thin-film transistor circuitry that is used in controlling light transmission through the array of pixels. The display layers may include a liquid crystal layer, polarizer layers, filter layers for reflecting red and green light and/or other light to enhance light recycling, and layers with angularly dependent transmission characteristics.Type: GrantFiled: August 31, 2017Date of Patent: March 17, 2020Assignee: Apple Inc.Inventors: Jean-Jacques P.

Patent number: 10395594Abstract: Methods, systems, and apparatuses for controlling an emission of the light emitting devices are described herein. The light emitting devices may be light emitting diode (LED) devices including ?LED devices or organic LED (OLED) devices. Emission control of the LED may be performed using a micro-scale driving circuit (e.g., ?Driver) containing drive transistors for constant current driving of the light emitting devices. One embodiment provides for a display driver hardware circuit including emission logic, the emission logic including comparator logic to compare a data voltage from a storage capacitor to a voltage ramp provided via the TFT backplane, the comparator logic to cause the emission logic to generate an emission pulse to an LED device, and wherein the integrated circuit is to switch and drive a plurality of LED devices. In one embodiment each of the plurality of LED devices is a subpixel for a display device.Type: GrantFiled: August 25, 2016Date of Patent: August 27, 2019Assignee: Apple Inc.Inventors: Thomas Charisoulis, Tore Nauta, Kapil Sakariya, Jean-Jacques P.
