Abstract: A display may include an active area with a first region and a second region. The first region may overlap an input-output component such as a camera and may have a higher transparency than the second region. The first region may have a lower pixel density than the second region. Signal lines that pass through the first region may have transparent portions that overlap the first region and opaque portions that overlap the second region. To mitigate artifacts caused by high resistance of the transparent portions of the signal lines, the signal lines may include supplemental opaque portions that are electrically connected in parallel to the transparent portions and that are routed through the second region around the first region.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The display may have both a full pixel density region and a pixel removal region with a plurality of high-transmittance areas that overlap the optical sensor. To mitigate reflectance mismatch between the full pixel density region and the pixel removal region, the pixel removal region may include a transition region at one or more edges. In the transition region, one or more components may have a gradual density change between the full pixel density region and a central portion of the pixel removal region. Components that may have a changing density in the transition region include dummy thin-film transistor sub-pixels, dummy anodes, a cathode layer, and a touch sensor metal layer. The transition region may also include anodes that gradually change shape and/or size.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. A pixel removal region on the display may at least partially overlap with the sensor. The pixel removal region may include a plurality of non-pixel regions each of which is devoid of thin-film transistors. The plurality of non-pixel regions is configured to increase the transmittance of light through the display to the sensor. In addition to removing thin-film transistors in the pixel removal region, additional layers in the display stack-up may be removed. In particular, a cathode layer, polyimide layer, and/or substrate in the display stack-up may be patterned to have an opening in the pixel removal region. A polarizer may be bleached in the pixel removal region for additional transmittance gains. The cathode layer may be removed using laser ablation with a spot laser or blanket illumination.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the optical sensor. Each transparent window may be devoid of thin-film transistors and other display components. The plurality of transparent windows is configured to increase the transmittance of light through the display to the sensor. The transparent windows may have non-periodic portions to mitigate diffraction artifacts in light that passes through the display to the optical sensor. The transparent windows may be shifted by a random amount in a random direction relative to a grid defining point and/or may be randomly rotated to increase the non-periodicity. A transparency gradient may be formed between the transparent windows and the surrounding opaque portion of the display. The transparent windows may be defined by non-linear edges.

Abstract: An electronic device may include a display and an optical sensor formed underneath the display. The electronic device may include a plurality of transparent windows that overlap the sensor. The resolution of the display panel may be reduced in some areas due to the presence of the transparent windows. To increase the apparent resolution of the display in portions of the display panel with the transparent windows, the display may include a light spreading layer that includes a plurality of diffractive elements. The light spreading layer may spread visible light from the array of pixels such that the display resolution at the outer surface of the display is greater than at the display panel. The light spreading layer may selectively spread visible light but not infrared light. The display may also include a lens layer that focuses light onto the transparent windows.

Abstract: An electronic device may have a display that displays an image. The image may be viewed through a display cover layer that overlaps the display. The display cover layer may include an optical coupling layer such as a coherent fiber bundle. A pixel expansion layer such as a diffractive layer may be incorporated between the optical coupling layer and a protective layer. The diffractive layer may create duplicate pixels to occupy otherwise non-light-emitting areas on the output surface of the display cover layer. The diffractive layer may also create duplicate pixels that overlap adjacent pixels to allow for brightness averaging. An adhesive layer or the protective layer may be used to form diffractive elements for the diffractive layer. An adhesive layer having a high index of refraction may be interposed between the optical coupling layer and the display panel to mitigate undesired reflections of ambient light.

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.
