View source for Light field display

{{stub}}
A '''light field display''' is a display that can display a [[light field]], which is light that a person can focus naturally on at a range of distances in the image. Light field displays can be made to be near the eye or fixed in the world: Either a [[near eye lightfield display]] or a [[world-fixed lightfield display]].

The light reaches the viewer from multiple angles at a single viewpoint.

A [[sequential light field display]] is a display that generates groups of rays at various focus distances one after another, and displays to the eye in rapid succession.

A simultaneous light field display is one that displays all of the light all at once. It uses a [[lens array]].

Light field displays can solve [[vergence-accommodation conflict]]s.
__NOTOC__
==Sequential==
Sequential light field displays have been developed by [[Andrew Maimone]] and [[CREAL]].

==Microlens-based==
{{detail|Microlens-based light-field display}}
A light field display can be made by putting a [[microlens array]] in front of a traditional flat display.<ref name="w353">{{cite web | title= | url=https://research.nvidia.com/sites/default/files/pubs/2013-11_Near-Eye-Light-Field/NVIDIA-NELD.pdf | access-date=2024-07-09}}</ref> This can be done by taking a laptop computer and putting a microlens sheet in front of it.

There is also the [[sequential light field display]].

==Manufacturing==
A light field display must be lit. For example using high brightness LEDs. The LEDs can be a broad backlight, or they can be the individual pixels or subpixels themselves.

Instead of using high-PPI displays, it is also feasible to use [[fiber optic image conduit]]s to transport light from a physically larger and high resolution display in a flexible way to a head-mounted apparatus, where microlensing can take place for light field generation.
