Abstract: In one example, a light-emitting diode display system includes one or more light-emitting diodes and a pixel driver circuit. The pixel driver circuit is to receive an input current, to produce a current that is dependent on the input current, and to provide the produced current to the one or more light-emitting diodes.

Abstract: A per-pixel performance improvement is described for combined image sensor arrays that measure infrared and visible light. One embodiment is a method that includes forming an array of photodetectors on a silicon substrate, treating a subset of the photodetectors to improve sensitivity to infrared light, and finishing the photodetector array to form an image sensor.

Abstract: In one example, a method for controlling a display with a digital signal includes detecting a binary value from a timing controller, the binary value corresponding to a portion of an image to be displayed. The method can also include determining a previous binary value from the timing controller and calculating a difference between the binary value from the timing controller and the previous binary value from the timing controller. Furthermore, the method can include generating an encoded signal based on the difference and transmitting the encoded signal to a display panel.

Abstract: A micro-LED includes a light emitter between a pair of reflective metasurfaces formed from nanostructures. The metasurfaces have different levels of reflectivity, with one metasurface reflecting nearly all light, and the other metasurface allowing some light to pass through. The reflections of the light within the micro-LED result in an improved radiation recombination rate, which results in an increased modulation speed. In addition, the light emitted from the micro-LED has a relatively narrow divergence angle and narrow emission linewidth, making the micro-LED suitable for optical communications.

Abstract: Technologies for chip-to-chip optical data transfer are disclosed. In the illustrative embodiment, microLEDs on a first chip are used to send data to microphotodiodes on a second chip. The beams from the microLEDs may be sent to the microphotodiodes using an optical bridge, microprisms, a channel through a substrate, a channel defined in a substrate, etc. The microLEDs may be used for high-speed data transfer with low power usage. A chip may include a relatively large number of microLEDs and/or microphotodiodes, allowing for a large bandwidth connection. MicroLEDs and microphotodiodes may be used to connect different parts of the same chip, different chips on the same package, different packages on the same device, or different chips on different devices.

Abstract: Emissive display devices having LED sources with super-lambertian radiation patterns. An exemplary emission source may have a half-emission-cone-angle of less than 40°. A system, such as an augmented reality display system, employing such an emissive display device may display a reduction in power of up to three times relative to LED sources with a lambertian radiation pattern. In some systems, such as augmented reality display systems, the optical path down stream of such an emissive display device may be simplified and/or dimensionally scaled, and/or manufactured to lower tolerances. For example, a discrete collimating lens may be eliminated from the optical path of such an emissive display device.
