    Abstract: A lensed beam-splitter prism array includes a beam-splitter substrate with a plurality of planar and parallel thin-film coatings each spanning a top substrate surface and a bottom substrate surface, and making an oblique angle therebetween, and a lens form layer formed on the top surface and having a plurality of lens forms, each lens form being above one of the plurality of coatings. A method for fabricating a lensed beam-splitter prism includes bonding a plurality of substrates to form a substrate stack having a coating between each adjacent substrate pair. The method also includes forming a stack slice by applying a plurality of parallel cuts at an oblique angle with respect to each coating. Each coating spans a first stack-slice surface and a second stack-slice surface opposing the first stack-slice surface. The method also includes forming a lens form layer on the first stack-slice surface spanning one or more coatings.

    Abstract: A near-eye display device includes (a) a display unit for displaying a display image, (b) a viewing unit for presenting the display image to the eye and transmitting ambient light from an ambient scene toward the eye, and (c) an eye imaging unit including (i) an illumination module for generating at least three infrared light beams propagating along at least three different, non-coplanar directions, respectively, (ii) a first beamsplitter interface, disposed between the display unit and the viewing unit, for merging at least a portion of each of the infrared light beams with visible display light to direct each portion toward the eye via the viewing unit, and (iii) a camera for imaging, via the viewing unit and the first beamsplitter interface, pupil of the eye and reflections of the infrared light beams incident on the eye, to form one or more images indicative of gaze direction of the eye.

    Abstract: A liquid crystal display includes a display area and a border area at least partially surrounding the display area, where the display area displays images for viewing and the border area displays display-protection images, which are used to control ion migration in the liquid crystal layer. In a more particular embodiment, the border area displays a series of checkerboard pattern(s), where the checkerboard patterns can alternate between initial and inverted values. The display-protection images protect the liquid crystal display from migrating ions accumulating in particular regions of the pixel array and causing permanent defects in the display area. A liquid crystal display that includes a liquid crystal alignment layer having a plurality of liquid crystal alignment directions is also disclosed. The customized liquid crystal alignment director(s) over the border area promote ion migration away from the display area.
