* '''CREAL (2020 onwards):''' A company developing compact lightfield display engines for AR, often using time-multiplexed micro-LED projection or scanning combined with holographic combiners. Prototypes aim for continuous focus (e.g., 0.15m to infinity) within a ~50-60° FoV in a glasses-like form factor<ref name="CrealWebsite">CREAL (n.d.). Technology.
