Patent number: 11910654Abstract: 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, the display may include active and/or passive leakage-mitigating structures. The passive leakage-mitigating structures may have an undercut that causes discontinuities in the overlying OLED layers. Active leakage-mitigating structures may include a conductive layer (e.g., a conductive ring) that drains leakage current to ground. Alternatively, the active leakage-mitigating structures may include a gate electrode modulator with a variable voltage that stops the current flow laterally.Type: GrantFiled: August 5, 2021Date of Patent: February 20, 2024Assignee: Apple Inc.Inventors: Po-Chun Yeh, Jiun-Jye Chang, Doh-Hyoung Lee, Caleb Coburn, Niva A.
