Abstract
In an embodiment, a headset display device includes a central processor and multiple projector integrated circuits each coupled to the central processor and configured to process image data. Each projector integrated circuit includes multiple first integrated circuits, each including a light emitter array. Each projector integrated circuit includes a second integrated circuit coupled to the multiple first integrated circuits. The second integrated circuit includes a graphics processor configured to generate transformed image data correcting for geometrical or brightness distortions and (2) is configured to provide the transformed image data to the multiple first integrated circuits for display.
