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 in a display, a cutting structure may disrupt continuity of the OLED layers. The cutting structure may have two undercuts to disrupt continuity of at least some of the OLED layers. The cutting structure may include a conductive portion that provides a cathode voltage to a cathode layer for the OLED pixels.

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.
