Abstract: Exemplary subpixel structures include a directional light-emitting diode structure characterized by a full-width-half-maximum (FWHM) of emitted light having a divergence angle of less than or about 10°. The subpixel structure further includes a lens positioned a first distance from the light-emitting diode structure, where the lens is shaped to focus the emitted light from the light-emitting diode structure. The subpixel structure still further includes a patterned light absorption barrier positioned a second distance from the lens. The patterned light absorption barrier defines an opening in the barrier, and the focal point of the light focused by the lens is positioned within the opening. The subpixels structures may be incorporated into a pixel structure, and pixel structures may be incorporated into a display that is free of a polarizer layer.

Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

Abstract: A plasma-assisted annealing system includes a high temperature furnace, a plasma-induced dissociator and a connecting duct. The plasma-induced dissociator is provided to dissociate a working gas and exhaust the dissociated working gas from its working gas outlet. Both ends of the connecting duct are connected to the working gas outlet of the plasma-induced dissociator and a gas inlet of the high temperature furnace, respectively. The working gas dissociated in the plasma-induced dissociator is introduced into the high temperature furnace via the connecting duct.

Abstract: The present invention provides a method for measuring the trimethylamine N-oxide (TMAO) production capacity in a subject, which comprises the following steps: (a) making the subject intake a specific dosage of carnitine; and (b) obtaining a body fluid sample of the subject at a specific time point after the subject ingests the carnitine and detecting the TMAO content in the body fluid sample. Different from the general technical detection on the market that only detects the gut microbiome composition, the invention can directly detect the ability of gut microbiota to produce TMAO in the human body. In addition, compared with directly detecting the concentration of TMAO in the blood, the invention gives a better predictive effect of gut microbiota functional phenotypes.
