Abstract: Methods and systems for creation of a flexible display panel, useable with a folding palm top or similar device, are disclosed. Embodiments include forming a micro-LED based display panel that uses a transparent flexible electrode. The transparent flexible electrode is fabricated from reduced graphene oxide and a wire mesh, to achieve a flexible electrode that is comparable to known Indium-Tin-Oxide electrodes in transparency and electrical characteristics, but is sufficiently flexible to support folding device usages. Other embodiments are described.

Abstract: A micro display, which includes LEDs and TFTs of a TFT electronic control circuit for controlling the LEDs, is produced monolithically on a silicon, silicon carbide, or sapphire wafer. The display includes red, green, and blue micro LEDs, and electronic control circuits include TFTs with Indium gallium zinc oxide (IGZO) channels or Indium phosphide (InP) channels. The TFTs are formed above the LEDs and laterally removed from the LEDs and paths of light emissions from the plurality of LEDs to prevent light blocking by the TFTs.

Abstract: Particular embodiments described herein provide for an electronic device that can be configured to include a user facing camera to capture a video stream of a user, a display presenting content, and display illumination logic to determine the user is insufficiently illuminated in the video stream, in response to the determination, reconfigure a first portion of the display as an illumination region and a second portion of the display as a content region, and increase the brightness of one or more pixels in the illumination region to better illuminate the user. In an example, the display includes micro light emitting diodes (microLEDs) and the one or more areas of the display in the full illumination configuration includes microLEDs at full brightness. In addition, in some examples, the content is resized to accommodate the one or more areas of the display that entered into the full illumination configuration.

Abstract: Per-pixel performance is improved in a combined visible and ultraviolet image sensor array such as for a hyperspectral camera. In one example, an array of photodetectors is formed on a silicon substrate. A subset of the photodetectors are improved to improve sensitivity to ultraviolet light, and the photodetector array is finished to form an image sensor.

Abstract: A laser source for use in a structured light projector includes a substrate, one or more first VCSELs on the substrate, and one or more second VCSELs on the substrate. The one or more first VCSELs each have a first aperture width and each separately extend above a surface of the substrate. The one or more second VCSELs each have a second aperture width different from the first aperture width, and each separately extend above a surface of the substrate. Using an array of VCSELs with different aperture widths provides emitted radiation having different wavelengths, thus providing different speckle patterns. When the different speckle patterns are averaged upon being received at the detector, speckle noise is reduced. The VCSEL can also include a plurality of subwavelength structures to steer the light output. Such subwavelength structures can also be used on the surface of other VCSELs, including standard VCSELs.
