Abstract: A display may include an array of pixels. Each pixel in the array includes an organic light-emitting diode coupled to associated semiconducting oxide transistors. The semiconducting oxide transistors may exhibit different device characteristics. Some of the semiconducting oxide transistors may be formed using a first oxide layer formed from a first semiconducting oxide material using first processing steps, whereas other semiconducting oxide transistors are formed using a second oxide layer formed from a second semiconducting oxide material using second processing steps different than the first processing steps. The display may include three or more different semiconducting oxide layers formed during different processing steps.

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.

Abstract: Systems and methods for through-display imaging. An optical imaging sensor is positioned at least partially behind a display and is configured to emit visible wavelength light at least partially through the display to illuminate an object, such as a fingerprint or a retina, in contact with or proximate to an outer surface of the display. Surface reflections from the object traverse the display stack and are received and an image of the object can be assembled.

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 electronic device includes a stack, and the stack includes a substrate, and a multi-layer structure deposited on the substrate and including a set of TFTs. The electronic device further includes a photodetector attached to the multi-layer structure and including an organic photosensitive material. The organic photosensitive material is electrically connected to a TFT in the set of TFTs. Another electronic device includes a stack, and the stack includes a substrate, and a multi-layer structure deposited on the substrate. The multi-layer structure includes a first set of layers including a set of TFTs, and a second set of layers including a PIN diode. The PIN diode is configured to operate as a photodetector and receive at least one wavelength of electromagnetic radiation, and is electrically connected to a TFT in the set of TFTs.
