CREAL logo

CREAL is a company that makes displays for augmented reality headsets. Specifically, 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 technology follows the work of Andrew Maimone in sequential light field displays.

CREAL's team included engineers from Intel's smart glasses project, as well as from Magic Leap.[3]

History[edit]

CREAL used DLP, then switched to LCOS. The switch was in part because LCOS can have its driving method controlled more directly.[4] DLP's drive algorithm is closed off by Texas Instruments.[4]

Display[edit]

CREAL has developed a small optical engine for light field display. It has 36 degree diagonal field of view.[5] The display surface has 91 percent transparency.[5]

CREAL AR prototype[edit]

The CREAL AR prototype is a prototype transparent display headset from CREAL.

Specifications[edit]

  • Angular resolution: about 40 pixels per degree[6]
  • Diagonal field of view: About 36 degrees[6]

Patents[edit]

  • US20240255762A1 - Near-eye sequential light-field projector with correct monocular depth cues[7]
  • US11960083B2 - Near-eye sequential light-field projector with correct monocular depth cues[8]
  • CA3172473A1 - Near-eye image projection system having foveated projection and expanded eye-box region[9]
  • US20210382307A1 - Light-field mixed reality system with correct monocular depth cues to a viewer[10]
  • WO2022175716A1 - Near-eye light-field display system having high efficiency and method of projecting a projection virtual pixel using the near-eye light-field display system[11]
  • EP4348335A1 - Light-field projector having a small form factor[12]
  • US20220404689A1 - Light-field virtual and mixed reality system having foveated projection [13]
  • US20230280586A1 - Near-eye image projection system and wearable device comprising said near-eye image projection system[14]
  • WO2022112818A1 - High-resolution light-field projector[15]
  • EP4252060A1 - High-resolution light-field projector
