A light field display is a display that can display a light field, which is light that a person can focus on naturally at a range of distances in the image. It is the most natural kind of 3D display, along with holographic displays. Light field displays can solve vergence-accommodation conflicts.
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.
Sequential
Sequential light field displays have been developed by Andrew Maimone and CREAL.
Microlens-based
- For detail about this topic, visit: Microlens-based light-field display
A light field display can be made by putting a microlens array in front of a traditional flat display.[1] 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 conduits 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.
