Abstract: A method, system, and article of efficient illuminator and camera sensor synchronization to capture images comprises generating a sequence of frames each associated with a captured image and comprising operating an electronic shutter using vertical-blanks (vblanks) occurring between the last reset of a previous frame and a first read of a current frame consecutively after the previous frame of the sequence of frames. The generating also comprises receiving, by at least one camera sensor, from at least one infra-red-related illuminator and limited to a time within or equal to the vblanks so that the illuminator is turned on and off at the same vblank, and sensing the received light at the camera sensor to convert the light into image data to form the frames in the sequence of frames.

Abstract: Disclosed herein are display panels, display panel stacks, and techniques to manufacture such display panel stacks where a polarizer is provided for each illumination element of the display panel stack. A polarizer can be formed onto each individual illumination element once the illumination element is transferred to the backplane. The polarizer can be arranged to polarize light emitted from the illumination element and light incident on the display from ambient.

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: A display panel is described which includes Light Emitting Diodes (LEDs) that exhibit a specified beam angle. The display panel can be used for a head-mounted display. An example of a head-mounted display includes a display panel with an array of LEDs that are controllable to form an image. The head-mounted display also includes circuitry to receive image data and render an image on the display panel. The head-mounted display also includes circuitry to detect motion of the head-mounted display. The image data is generated based in part on the motion of the head-mounted display. Each LED in the array of LEDs is configured to emit light at a specified beam angle that directs the light toward a pupil of a wearer of the head-mounted display.
