Publication number: 20230301131Abstract: Pixels in an organic light-emitting diode (OLED) display may be microcavity OLED pixels having optical cavities. The optical cavities may be defined by a partially transparent cathode layer and a reflective anode structure. The anode of the pixels may include both the reflective anode structure and a supplemental anode that is transparent and that is used to tune the thickness of the optical cavity for each pixel. Organic light-emitting diode layers may be formed over the pixels and may have a uniform thickness in each pixel in the display. Pixels may have a conductive spacer between a transparent anode portion and a reflective anode portion, without an intervening dielectric layer. The conductive spacer may be formed from a material such as titanium nitride that is compatible with both anode portions. The transparent anode portions may have varying thicknesses to control the thickness of the optical cavities of the pixels.Type: ApplicationFiled: May 24, 2023Publication date: September 21, 2023Inventors: Gloria Wong, Jaein Choi, Sunggu Kang, Hairong Tang, Xiaodan Zhu, Wendi Chang, Kanuo C. Kustra, Rui Liu, Cheng Chen, Teruo Sasagawa, Wookyung Bae

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

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 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.
