Publication number: 20260090250Abstract: Pixels in an organic light-emitting diode (OLED) display may have optical cavities defined by a partially transparent cathode layer and a reflective anode structure. Light at a wavelength emitted by a pixel may form a standing wave between the anode and the cathode. The standing wave may have an upper antinode and a lower antinode. Pixels of different colors may have emissive layers aligned with different antinodes. The OLED layers for the pixels may include an electron transport layer that is doped with a low work function material. The cathode may include one or more layers of transparent conductive oxide and/or metal. The cathode may be shorted to a metal mesh and/or a conductive cutting structure to decrease resistance.Type: ApplicationFiled: July 23, 2025Publication date: March 26, 2026Inventors: Yue Qu, Chih-Lei Chen, Chun-Kai Chang, Hoyeon Kim, KiBeom Kim, Kwang Ohk Cheon, Li-An Liu, Liping Zhu, Ming-Hung Huang, Pei-Ling Lin, Rui Liu, Shiyi Liu, Sukru Ekin Kocabas, Wendi Chang, Xiangyu Fu, Yifan Zhang, Younggu Lee, Yun Liu, Xiao Li, Yu Wang

Publication number: 20260007036Abstract: A display may include organic light-emitting diode (OLED) pixels. Each pixel may include OLED layers that are interposed between an anode and a cathode. The anode may be formed on a substrate. A layer of material that defines a plurality of bumps or recesses may be formed on the substrate. The anode may conform to the layer of material and may have a plurality of curved portions that are aligned with the bumps or recesses. The anode may have a side mirror portion that conforms to a tapered surface. A black pixel definition layer may be positioned above or below the side mirror portion of the anode. A pixel may include a pixel definition layer that defines multiple light-emitting apertures that overlap a single anode. The multiple light-emitting apertures may have circular, square, or non-square rectangular footprints.Type: ApplicationFiled: May 6, 2025Publication date: January 1, 2026Inventors: Yue Qu, Chih-An Huang, Chih-Lei Chen, Chuan-Jung Lin, Chun-Kai Chang, David A.

Publication number: 20240210995Abstract: A display may have a stretchable portion with hermetically sealed rigid pixel islands. A flexible interconnect region may be interposed between the hermetically sealed rigid pixel islands. The hermetically sealed rigid pixel islands may include organic light-emitting diode (OLED) pixels. A conductive cutting structure may have an undercut that causes a discontinuity in a conductive OLED layer to mitigate lateral leakage. The conductive cutting structure may also be electrically connected to a cathode for the OLED pixels and provide a cathode voltage to the cathode. First and second inorganic passivation layers may be formed over the OLED pixels. Multiple discrete portions of an organic inkjet printed layer may be interposed between the first and second inorganic passivation layers.Type: ApplicationFiled: October 10, 2023Publication date: June 27, 2024Inventors: Prashant Mandlik, Bhadrinarayana Lalgudi Visweswaran, Mahendra Chhabra, Chia-Hao Chang, Shiyi Liu, Siddharth Harikrishna Mohan, Zhen Zhang, Han-Chieh Chang, Yi Qiao, Yue Cui, Tyler R Kakuda, Michael Vosgueritchian, Sudirukkuge T.

Patent number: 10658441Abstract: A display may have an array of pixels formed from organic light-emitting diodes and thin-film transistor circuitry. Each pixel may include organic layers interposed between an anode and a cathode. The organic layers may emit out-coupled light that escapes the display and waveguided light that is waveguided within the organic layers. A reflector may be placed at the edge of the organic layers to reflect the waveguided light out of the display. The reflector may be located within a pixel definition layer and may be formed from metal or may be formed from one or more interfaces between high-refractive-index material and low-refractive-index material. The reflector may be formed from an extended portion of the pixel anode. The reflector may be formed from light-reflecting particles that are suspended in the pixel definition layer.Type: GrantFiled: August 27, 2018Date of Patent: May 19, 2020Assignee: Apple Inc.Inventors: Kwang Ohk Cheon, Cheng Chen, Chien Lu, Chih-Lei Chen, Chin Wei Hsu, Hui Lu, KiBeom Kim, Lun Tsai, Meng-Huan Ho, Nai-Chih Kao, Pei-Ling Lin, Rui Liu, Shan-Jen Yu, Wendi Chang, Yusuke Fujino
