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.

Abstract: A thin film transistor (TFT) to control a light emitting diode (LED) or an organic light emitting diode (OLED) includes a channel region configured as a saddle channel extending between the drain region and the source region of the TFT. The saddle channel is formed by deposition of channel material on a fin structure, and the contour of the saddle channel is defined by the contour of the fin structure. Deposition of the channel material for the saddle channel may be performed by: (i) atomic layer deposition (ALD) of amorphous silicon; (ii) ALD of amorphous silicon followed by annealing to form polycrystalline silicon; or (iii) deposition of indium gallium zinc oxide (IGZO) material by one of ALD, plasma-enhanced atomic layer deposition (PEALD), chemical vapor deposition (CVD), or plasma-enhanced chemical vapor deposition (PECVD).

Abstract: The present disclosure is directed to systems and methods useful for providing a metasurface lens formed by a plurality of multi-piece optical structures disposed on, about, or across at least a portion of the surface of substrate member. Each of the plurality of multi-piece optical structures includes a solid cylindrical core structure surrounded by a hollow cylindrical core structure such that a gap having a defined width forms between the solid cylindrical core structure and the hollow cylindrical structure surrounding the solid core. The width of the gap determines the optical performance of the metasurface lens. The multi-component optical structures forming the metasurface lens advantageously produce little or no phase shift in the electromagnetic energy passing through the metasurface lens, thereby beneficially providing an optical device having minimal or no dispersion and/or chromatic aberration.

Abstract: A smart display including one or more groups of smart pixels and at least one graphics engine. The at least one graphics engine is fragmented into GPU (graphics processing unit) minute cores. The GPU minute cores are distributed throughout the smart display. The smart pixels with distributed graphics within the smart display perform deep learning. Libraries stored on GPU minute core embedded memory are used to perform object identification using deep learning. The smart display monitors for pixel degradation and, if necessary, performs pixel enhancement.

Abstract: Systems, apparatuses and methods may provide for technology that partitions a high dynamic range (HDR) image into a plurality of regions and determines, on a per region basis, a luminance level of the HDR image. Additionally, the technology may select, on the per image basis, a encoding amount for each region in the plurality of regions based on the luminance level.

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.
