Abstract: A display may overlap a sensor such as a camera or ambient light sensor. A portion of the display that overlaps the sensor may be modified to increase transparency relative to the remaining portion of the display. The modified portion of the display may have pixel islands that conform to a regular grid pattern of the remaining portion of the display. One or more gate lines and/or one or more data lines may pass through the modified portion of the display without connecting to any subpixels in the modified portion of the display. An opaque pixel definition layer may include some openings that are aligned with opaque masking layer openings to allow on-axis light to pass through to a sensor and some openings that are offset relative to respective opaque masking layer openings to allow off-axis light to pass through to the sensor.

Abstract: An electronic device and methods of fabrication are disclosed. In an embodiment, an electronic device includes a display panel including a display area, a peripheral edge surrounding the display area, and a border region along the peripheral edge and surrounding the display area. The display panel may further include an array of pixel driver chips, a redistribution layer (RDL) over the array of pixel driver chips, and an array of light-emitting diodes (LEDs) mounted on the RDL within the display area, where the RDL includes a metal seal ring in the border region.

Abstract: An electronic device may have a display with an array of inorganic light-emitting diodes. The array of inorganic light-emitting diodes may be overlapped by a polarizer layer such as a circular polarizer. Alternatively, the display may be a polarizer-free display without any polarizer layer over the array of inorganic light-emitting diodes. Each inorganic light-emitting diode may be surrounded by a diffuser that redirects edge-emissions towards a viewer. A top diffuser, a color filter layer, a microlens, and/or a microlens with color filtering and/or diffusive properties may also optionally overlap each inorganic light-emitting diode. The inorganic light-emitting diodes may have reflective sidewalls to mitigate edge-emissions. In this type of arrangement, the array of inorganic light-emitting diodes may be coplanar with one or more opaque masking layers. To mitigate reflections, the display may include two opaque masking layers having differing properties or a single phase separated opaque masking layer.

Abstract: To extract light from a light-emitting diode (and thereby improve efficiency of the display), a microlens stack may be formed over the light-emitting diode. The microlens stack may include an array of microlenses that is covered by an additional single microlens. Having stacked microlenses in this way increases lens power without increasing the thickness of the display. The array of microlenses may be formed from an inorganic material whereas the additional single microlens may be formed from an organic material. The additional single microlens may conform to the upper surfaces of the array of microlenses. An additional low-index layer may be interposed between the light-emitting diode and the array of microlenses. A diffusive layer may be formed around the light-emitting diode to capture light emitted from the light-emitting diode sidewalls.
