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 rays one by one, or in groups 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.
Light field displays can solve most [[vergence-accommodation conflict]]s.
==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.
==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.
