Abstract: 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.

Abstract: An organic light-emitting diode (OLED) display includes an array of OLED pixels and an array of organic photodetector (OPD) pixels. An OLED pixel in the array of OLED pixels includes an OLED hole transport layer (HTL), an OLED electron transport layer (ETL), and an emissive layer positioned between the OLED HTL and the OLED ETL. An OPD pixel in the array of OPD pixels includes the OLED HTL, the OLED ETL, and an electron donor material positioned between the OLED HTL and the OLED ETL, wherein the OLED ETL functions as an electron acceptor material for the OPD pixel. In other embodiments, the OPD pixel may be configured differently.

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, resistance of a laterally conductive OLED layer may be increased. The laterally conductive layer may include an organic host material, dopants, and a resistance-increasing additive. Another way to reduce leakage current is to apply bias voltages to the anodes of the display and/or expose the laterally conductive layer to ultraviolet light, causing dopants within the laterally conductive layer to degrade.
