Abstract:
An optical reader system and method are described herein that can detect a lateral and/or angular misalignment of one or more biosensors so that the biosensors can be properly re-located after being removed from and then reinserted into the optical reader system. In one embodiment, the biosensors are incorporated within the wells of a microplate.

Abstract:
A protected organic light emitting diode includes an organic light emitting diode structure formed on a substrate, a hermetic barrier layer formed over at least part of the organic light emitting diode structure, and a light extraction layer. The barrier layer may include a glass material such as a tin fluorophosphate glass, a tungsten-doped tin fluorophosphate glass, a chalcogenide glass, a tellurite glass, a borate glass or a phosphate glass. The light extraction layer, which may be formed over the barrier layer, includes a high refractive index matrix material and at least one of scattering particles dispersed throughout the matrix material and a roughened surface.
Abstract:
Embodiments are generally directed to autostereoscopic display device illumination apparatuses having one or more optical fibers (i.e., flexible light diffusing waveguides) as linear emitters for illuminating columns of pixels of a display panel within the autostereoscopic display device. In some embodiments, the linear emitters are defined by a single optical fiber that is arranged on a substrate in a serpentine manner to form an array of linear emitters. In some embodiments, the linear emitters are defined by several optical fibers. Illumination apparatuses of some embodiments may also include a prism device configured to create multiple images of the optical fiber(s).
Abstract:
A method of making a glass lenticular array is provided. The method comprises: heating a sheet of glass, the sheet of glass comprising contact regions located thereupon in substantially parallel linear rows; and deforming the heated sheet of glass by contacting the contact regions with a forming body so as to form a plurality of cylindrical lenses in the heated sheet of glass, the plurality of cylindrical lenses arranged in substantially parallel rows with depressed regions between adjacent cylindrical lenses. The depressed regions are formed at the contact regions while apex regions of the cylindrical lenses are kept untouched during the step of deforming.
Abstract:
Bezel-concealing display covers and display devices are disclosed. In one example, a bezel-concealing display cover includes a bezel and a display panel includes a perimeter portion having a first surface and a second surface such that the perimeter portion is configured to be offset from the bezel of the display device by a gap GA. The bezel-concealing display cover further includes a first array of prisms on at least one of the first surface or the second surface of the perimeter portion that extend from an edge of the perimeter portion to a distance L. Each prism of the first array of prisms has a prism angle θ, and the first array of prisms is configured to shift a portion of an image proximate the bezel produced by the display panel such that the shifted portion of the image appears over the bezel to an observer.
Abstract:
A transparent substrate having an antiglare surface with reduced display sparkle. The transparent substrate has a roughened antiglare surface and a diffraction element below the antiglare surface. The diffraction element reduces sparkle by filling gaps between sub-pixels in a pixelated display with orders of diffraction. A display system comprising the transparent substrate and a pixelated display is also provided.
Abstract:
An apparatus and method for determining and quantifying “sparkle”—the random noise that is generated when a pixelated image is viewed through a roughened surface of a transparent sample. The apparatus includes a pixelated source and an imaging system located in an optical path originating from the pixelated source, wherein a transparent sample may be placed in the optical path between the pixelated source and the optical system. The degree of sparkle is determined by obtaining an integrated image for the pixelated image; and calculating a standard deviation of the integrated pixel power. An objective level of sparkle can be defined by correlating the amount of sparkle provided by the apparatus with visual impressions.

Abstract:
Methods for operating a light source of a scanning laser projector to reduce speckle and image flicker in projected images are disclosed. The methods generally include projecting an image comprising a plurality of frames with a light source of the scanning laser projector. Simultaneously, a speckle reduction sequence comprising uncorrelated speckle patterns and partially correlated speckle patterns is projected with the light source of the scanning laser projector. The speckle reduction sequence is projected by varying a property of an output beam of the light source of the scanning projector. The duration of the speckle reduction sequence may be less than about 0.04 seconds or from about 0.07 seconds to about 0.13 seconds.
