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.

Abstract: A near-eye display device, with coaxial eye imaging, for mounting in field of view of an eye of a user, includes a display unit for displaying a display image, a viewing unit for (i) presenting the display image to the eye based upon polarized visible light received from the display unit and (ii) transmitting ambient light from an ambient scene toward the eye, and an eye imaging unit including (a) an illumination module for generating infrared light, (b) a first polarizing beamsplitter interface, disposed between the display unit and the viewing unit, for (i) merging a polarized infrared component of the infrared light with the polarized visible light and (ii) separating from the polarized visible light a portion of the polarized infrared component reflected by the eye, and (c) a camera for forming an image of the eye based upon the polarized infrared component reflected by the eye.
