CREAL is a company that makes displays for augmented reality headsets. Specifically, sequential light-field displays.[1]

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.[2]

One of CREAL's patents details the use of a 2D point light array as the light source that is lit up sequentially.[3] Each point light is a source of light such as an LED that has a pinhole mask.

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

Display

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

It has 36 degree diagonal field of view.[4]

The display surface has 91 percent transparency.[4]
