Abstract: A liquid crystal pixel includes liquid crystals, a source electrode, and a transparent common electrode layer. The liquid crystals are configured to change an alignment of the liquid crystals in response to a voltage applied across the source electrode and the transparent common electrode layer. The slit in the transparent common electrode layer includes multiple angled sections.

Abstract: A liquid crystal display (LCD) system for a head mounted display includes an LCD panel and a backlight unit. The LCD panel includes a color filter on array (COA) configuration. The backlight unit includes a light adjustment layer to adjust at least one characteristic of illumination light from a light source to tune the illumination light for enlarging an emission cone of display light.

Abstract: Narrowing of an eyebox in a display including a display panel and an ocular lens caused by uniform illumination of the display panel may be reduced by using a redistributor that provides a spatially variant angular distribution of brightness matched to performance of the ocular lens. When a beam of light from a pixel of the display panel has a first dependence of a beam coordinate at the image plane upon a pixel coordinate at the object plane when the display panel is illuminated with light having a spatially uniform angular distribution of brightness, the redistributor may be configured to convert the spatially uniform angular distribution of brightness of light illuminating the display panel into a spatially non-uniform angular distribution of brightness for lessening the first dependence.
