Abstract
A 3D near eye display device is provided, the display device comprising a display screen for displaying more than one 2D images, at least one focusing element for collimating the images to sub-images, a spatial multiplexing unit capable of remapping the sub-images to different depths while forcing their centers to align to form remapped sub-images, and an eye piece. The device and methods allow for a high quality, compact 3D display system that can be wearable and overcomes the vergence-accommodation conflict that leads to visual discomfort and fatigue caused by traditional 3D near eye display devices.
Claims20
A display device comprising:
- a focusing element that collimates a plurality of two dimensional images that are displayed on a display screen;
- and
- a spatial multiplexing unit that remaps the plurality of two dimensional images to different depths while forcing centers of the plurality of two dimensional images to align.
A method comprising:
- collimating, by a focusing element, a plurality of two dimensional images that are displayed on a display screen;
- and
- modifying, by a spatial multiplexing unit, a phase of light transmitted from the focusing element by adding one or more quadratic phase terms and one or more linear phase terms to a wave front of the light, wherein the modifying results in multiplane images.
A display device comprising:
- a beam splitter having a first surface and a second surface, wherein the first surface aligns with a first panel that displays a first two dimensional image, wherein the second surface aligns with a second panel that displays a second two dimensional image, and wherein the beam splitter combines first light emanating from the first panel and second light emanating from the second panel, resulting in combined light;
- an actuator configured to slide the beam splitter in a direction along the first panel to adjust a gap between the second panel and the second surface of the beam splitter;
- and
- a focusing element that projects each of a plurality of images in the combined light to a respective distinct one of a plurality of different depth planes.
