A near-eye display is a visual display that is near the eye. It can be in pairs, so that the left and right eye each see their own near-eye displays.
It can be used in a stereoscopic pair for example in a VR headset. Two near-eye displays are used in VR headsets, one for each eye.
Near-eye displays can be classified in a number of ways. The most common types of near-eye display are transparent head-up displays (HUDs) and VR headset displays. The VR headset displays are typically opaque, meaning they block out the light from behind it.
Near-eye displays classically are driven using a two-dimensional array of pixels, similar to a traditional screen. However, to have a full 3D visual experience, a near eye display must display a light field, or at least more focal cues.
Transparent near-eye displays consist of an image generator (such as an LCOS microprojector) and an optical combiner.[1]
