A multifocal display is a display that can show multiple foci at once, thereby having a natural 3D effect.
A multifocal display can be head-mounted, or instead, part of a device that is separate from the head like on a computer screen or laptop computer.
Head-mounted multifocal displays are generally made using a sequential focal stack, where very quickly multiple images are shown and the focus of the optical system changes at the same time. It happens so quickly it all looks like one image.
The sequential focal stack method is used by Lightspace Technologies and CREAL, in varying methods.
