Abstract: 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.

A lane closure zone can include any area where a lane is closed off. The changes to the typical travel paths for vehicles on the roadway can indicate that vehicles are to travel along a different path than that indicated on the maps the AVs use to operate. Thus, it is important for accurate driving operations of the AVs for the AVs to be able to interpret the changes to the typical travel paths indicated by the lane closure. Navigating through lane closure zones generally includes mapping (by the AV) objects in the lane closure zone, including the objects indicating the lane closure, and understanding related surrounding non-player characters (e.g., other vehicles).
