Abstract: The invention relates to a light redirecting film comprising a thin optically transparent substrate having opposite sides, one side of the substrate substantially covered by elongated individual optical elements whose longest dimensions are substantially aligned in a lengthwise direction, wherein the shape of at least some of the optical elements have a visually significant difference, and wherein the layout of optical element shapes and locations is such that objectionable patterns are not visible in the film under standard LCD backlight viewing conditions.

Abstract: A system and method of detecting a type of media for an imaging apparatus. In the system and method of the present invention, a backside of the media is scanned or read to detect the presence of indicia on the backside of the media. The spacing between the repeated indicia on the media is measured for the purpose of detecting the type of media. That is, the system of the present invention includes a sensor that makes sequential spatial measurements of a moving media that contains repeated indicia to determine a repeat frequency and repeat distance of the indicia. The repeat distance is then compared against known values to determine the type of media present.

Abstract: A method of determining defects in OLED devices having a plurality of pixels, each with its own emissive layer, which are capable of being excited by input light to produce an output color light response, including illuminating one or more OLED devices or a portion of an OLED device with light in a predetermined portion of the spectrum so that the pixel emissive layers are excited to produce an output color response for each pixel, capturing an image of the output light produced by the excited pixels and converting such captured light into a digital image; and determining device pixel size, shape, location, and emitted light intensity from the digital image and comparing such size, shape, location, and emitted light intensity with predetermined acceptable size, shape, location, and emitted light intensity ranges to determine whether there is a defect in the OLED device(s).
