Patent number: 11778856Abstract: An electronic device may have a support structure that supports a display and lenses. Each lens may be a reflective lens such as a catadioptric lens that receives polarized image light from the display and provides a corresponding image to an eye box. The display may be an emissive display with pixels that include light-emitting diodes. The light-emitting diodes may be overlapped by a light recycling layer such as a reflective polarizer or cholesteric liquid crystal layer. The light recycling layer recycles emitted light to enhance display efficiency.Type: GrantFiled: February 26, 2020Date of Patent: October 3, 2023Assignee: Apple Inc.Inventors: Aleksandr N. Polyakov, Aditi G. Kanhere, Brandon E. Clarke, Cheng Chen, John N. Border, Nan Zhu, Rui Liu, Wei-Liang Hsu

Publication number: 20230111407Abstract: An electronic device includes a frame and a display stack. The frame defines a first part of an interior volume. The display stack includes a cover attached to the frame. The cover may define a second part of the interior volume. The display stack also includes an array of organic light-emitting diodes (OLEDs) including an array of emissive electroluminescent (EL) regions, and at least one organic photodetector (OPD) disposed between the cover and at least one emissive EL region in the array of emissive electroluminescent regions. The at least one emissive EL region emits light through the at least one OPD. In alternative embodiments, the OLEDs may be stacked on the OPDs, or the OLEDs and OPDs may be interspersed with each other instead of stacked.Type: ApplicationFiled: December 12, 2022Publication date: April 13, 2023Inventors: Niva A. Ran, Aleksandr N. Polyakov, Lun Tsai, Meng-Huan Ho, Mohammad Yeke Yazdandoost

Publication number: 20220317820Abstract: Visibility of the metal mesh touch electrodes can be mitigated using one or more mitigation techniques. In some examples, the boundary between touch electrodes and/or the boundary between a touch electrode and a routing trace of another touch electrode and/or the boundary between two routing traces can be non-linear. In some examples, dummy cuts can be made within an area of a touch electrode region (e.g., while maintaining the same electrical potential for the touch electrode region). In some examples, notches can be made in the metal mesh. In some examples, the location of cuts and/or notches can be optimized to mitigate visibility of the metal mesh. In some examples, some or all of the visibility mitigations may be used in combination in a touch screen.Type: ApplicationFiled: June 15, 2022Publication date: October 6, 2022Inventors: Tiffany Tang MOY, Tsung-Ting TSAI, Warren S. A. RIEUTORT-LOUIS, Aleksandr N. POLYAKOV, Chuang QIAN, Sabino Joseph PIETRANGELO, II, Abbas JAMSHIDI-ROUDBARI, Rui LIU, Yurii MOROZOV

Patent number: 11211587Abstract: A display may have an array of organic light-emitting diode (OLED) pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and cross-talk, the thickness of at least one of the OLED layers may be reduced. To maintain the optical cavity of the pixels, transparent optical spacer structures may be inserted. Alternatively, the thickness of the anodes can be increased. To accommodate a common prime layer within the OLED layers, the optical spacers or anodes may be separately patterned to have different thicknesses. Grating structures and photonic crystal structures may be embedded as part of the optical spacers to help control emission at selected viewing angles.Type: GrantFiled: July 25, 2019Date of Patent: December 28, 2021Assignee: Apple Inc.Inventors: Kwang Ohk Cheon, Aleksandr N.

Patent number: 10614752Abstract: An electronic device may be provided with an ambient light sensor. The ambient light sensor may be a color ambient light sensor or a monochrome ambient light sensor. The electronic device may have a light-emitting component such as a display. During operation of the display, the display emits light. To reduce noise due to the emitted light while measuring ambient light, the ambient light sensor may have optical structures such as wave plates and polarizers. Theses optical structures may overlap light detectors. The optical structures may be configured to prevent ambient light from reaching a first of the light detectors while allowing ambient light to reach a second of the light detectors. The ambient light sensor may be configured to receive ambient light that has passed thorough an inactive area of a display or that has passed through a pixel array in an active area of a display.Type: GrantFiled: September 27, 2018Date of Patent: April 7, 2020Assignee: Apple Inc.Inventors: Christopher M. Dodson, Aleksandr N. Polyakov, Guocheng Shao, Meng-Huan Ho, Niva A. Ran, Serhan O. Isikman, Volodymyr Borshch
