Appl. No.:

13/931241

International Classification:

G02B 27/01

US Classification:

345589, 345 8

Abstract:

Technology is disclosed for optimizing a near-eye display using a waveguide. A first waveband for a first color narrower than the full spectral bandwidth for the first color and a second waveband for a second color adjacent to the first color in the visible spectrum are generated in image light of an image generation unit like a microdisplay. The first waveband and the second waveband are coupled into a same layer of a diffractive waveguide. An input grating of the same layer of the waveguide has a grating wavelength band approximately matching a waveband extensive with the first waveband and the second waveband. A converted green light emitting diode (LED) may be used for obtaining a first waveband centered around 515 nm in some examples. One of more of the wavebands may be obtained using filters, for example filters using dichroic mirrors, quantum dots or a combination of these.

Abstract:

Embodiments are disclosed that relate to displaying images on multi-display devices with low latency. For example, one disclosed embodiment provides, on a display device comprising a first display and a second display, a method comprising receiving, processing a first image, and displaying the first image via the first display and not displaying the first image via the second display. The method further comprises receiving a second image, processing the second image while displaying the first image, and displaying the second image via the second display and not displaying the second image via the first display.
