Publication number: 20240081134Abstract: A hybrid display may include different display portions with different resolutions. The high resolution display portion may be positioned in a main viewing area for the viewer whereas the low resolution display portion may be positioned in a peripheral viewing area. The high resolution display portion may have a silicon backplane. The low resolution display portion may have a different type of backplane such as a thin-film transistor backplane. The different display portions may optionally share a common organic light-emitting diode layer such that light is emitted from the same plane across both display portions. The high resolution display portion may emit light through a transparent window in the low resolution display portion. A high resolution display may also be formed by separately forming a frontplane and a backplane. Conductive attachment structures such as indium bumps may be used to mechanically and electrically connect the backplane to the frontplane.Type: ApplicationFiled: June 5, 2023Publication date: March 7, 2024Inventors: James E Pedder, Patrick B Bennett, Michael Slootsky, Graham B Myhre, Andrew Lin, Cheuk Chi Lo, Guanjun Tan

Patent number: 11744097Abstract: Arrangements and techniques for providing organic emissive layers are provided, in which the emissive layer includes a first dopant having a dissociative energy level. A second dopant in the emissive layer provides a solid state sink energy level, to which doubly excited excitons and/or polarons may transition instead of to the dissociative energy level, thereby decreasing the undesirable effects of transitions to the dissociative energy level.Type: GrantFiled: May 11, 2021Date of Patent: August 29, 2023Assignees: THE REGENTS OF THE UNIVERSITY OF MICHIGAN, THE UNIVERSITY OF SOUTHERN CALIFORNIAInventors: Stephen R. Forrest, Michael Slootsky, Mark E. Thompson

Publication number: 20230240100Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode 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 the accompanying cross-talk in a display, the pixel definition layer may disrupt continuity of the OLED layers. The pixel definition layer may have an undercut to disrupt continuity of some but not all of the OLED layers. The undercut may be defined by three discrete portions of the pixel definition layer. The undercut may result in a void that is interposed between different portions of the OLED layers to break a leakage path formed by the OLED layers.Type: ApplicationFiled: March 31, 2023Publication date: July 27, 2023Inventors: Jaein Choi, Hairong Tang, Gloria Wong, Sunggu Kang, Younggu Lee, Gwanwoo Park, Chun-Yao Huang, Andrew Lin, Cheuk Chi Lo, Enkhamgalan Dorjgotov, Michael Slootsky, Rui Liu, Wendi Chang, Cheng Chen

Publication number: 20230062202Abstract: An electronic device may have a display. The display may include an array of pixels formed on a silicon substrate. Display driver circuitry may be formed in a display driver integrated circuit that outputs display data and other control signals for operating the display. An interposer structure may be included in the electronic device. The interposer structure may be attached to the silicon display substrate and may only partially overlap the silicon display substrate. The display driver integrated circuit may be attached to the interposer structure and provide signals to the display pixels through the interposer structure. In another possible arrangement, the display driver integrated circuit may bridge a gap between the silicon display substrate and the flexible printed circuit. The display driver integrated circuit only partially overlaps the silicon display substrate in this arrangement.Type: ApplicationFiled: May 26, 2022Publication date: March 2, 2023Inventors: Steven M Scardato, Baris Cagdaser, Patrick B Bennett, Michael Slootsky, Alejandro X Levander, Henry C Jen

The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display.

The pixel definition layer may have a steep sidewall, a sidewall with an undercut, or a sidewall surface with a plurality of curves to disrupt continuity of the OLED layers. A control gate that is coupled to a bias voltage and covered by gate dielectric may be used to form an organic thin-film transistor that shuts the leakage current channel between adjacent anodes on the display.Type: GrantFiled: April 27, 2018Date of Patent: April 19, 2022Assignee: Apple Inc.Inventors: Jaein Choi, Andrew Lin, Cheuk Chi Lo, Chun-Yao Huang, Gloria Wong, Hairong Tang, Hitoshi Yamamoto, James E.

Publication number: 20220013672Abstract: There is disclosed ultrahigh-efficiency single- and multi-junction thin-film solar cells. This disclosure is also directed to a substrate-damage-free epitaxial lift-off (“ELO”) process that employs adhesive-free, reliable and lightweight cold-weld bonding to a substrate, such as bonding to plastic or metal foils shaped into compound parabolic metal foil concentrators. By combining low-cost solar cell production and ultrahigh-efficiency of solar intensity-concentrated thin-film solar cells on foil substrates shaped into an integrated collector, as described herein, both lower cost of the module as well as significant cost reductions in the infrastructure is achieved.Type: ApplicationFiled: September 24, 2021Publication date: January 13, 2022Inventors: Stephen R.

Patent number: 11105963Abstract: Optical systems may have tunable lenses with focal lengths that are adjusted by control circuitry. A display may produce image light that is received by a tunable lens. The display may be transparent so that light from objects can pass through the display and be received by the tunable lens. The tunable lens may include a birefringent lens element and a polarization rotator and may receive light that has been linearly polarized by passing through a linear polarizer. The polarization rotator may be operable in a first state in which the polarization of light passing through the polarization rotator is not rotated and a second state in which the polarization of light passing through the polarization rotator is rotated by 90°. The birefringent lens element may be formed from a cured liquid crystal polymer or other polymer and may have a liquid crystal additive to enhance birefringence.Type: GrantFiled: March 9, 2017Date of Patent: August 31, 2021Assignee: Apple Inc.Inventors: Yuan Chen, Bennett S.
