CREAL is a company that develops sequential light-field displays.

Its displays are near-eye light field displays. CREAL has marketed displays as suitable for AR glasses.

CREAL had planned to make a fixed foveated display.[1]

One of CREAL's patents details the use of a 2D point light array as the light source that is lit up sequentially.[2] Each point light is a source of light such as an LED that has a pinhole mask.

CREAL's work is influenced by the work of Andrew Maimone.

Display[edit]

CREAL has developed a small optical engine for light field display.

It has 36 degree diagonal field of view.[3]

The display surface has 91 percent transparency.[3]
