Abstract: Methods and apparatus for eye-glow suppression in waveguide systems is disclosed herein. Some embodiments of the methods and the apparatus include a source of image modulated light; a waveguide having an eye-facing surface and an external surface facing the outside world; an input coupler for coupling the light into a total reflection internal path in the waveguide; at least one grating for providing beam expansion and extracting light from the waveguide towards an eyebox; a polymer grating structure comprising a modulation depth and a grating pitch. The modulation depth is greater than the grating pitch across at least a portion of the polymer grating structure. Advantageously, the polymer grating structure is configured to diffract light entering the waveguide from the outside world or stray light generated within the waveguide away from optical paths that are refracted through the external surface into the outside world.

Abstract: Disclosed herein are systems and methods for providing waveguide display devices utilizing overlapping integrated dual axis (IDA) waveguides. One embodiment includes a waveguide display device including: a first input image source providing first image light; a second input image source provide second image light; a first IDA waveguide; and a second IDA waveguide. The first IDA waveguide and the second IDA waveguide may include an overlapping region where a first two-dimensionally expanded first image light, a second two-dimensionally expanded first image light, a first two-dimensionally expanded second image light, and a second two-dimensionally expanded second image light is ejected towards an eyebox. Advantageously, resolution may be enhanced and field of view may be expanded through the use of overlapping IDA waveguides.

Abstract: Methods and apparatus for eye-glow suppression in waveguide systems is disclosed herein. Some embodiments of the methods and the apparatus include a waveguide based display including a waveguide including an in-coupling optical element and an out-coupling optical element, where the in-coupling optical element is configured to in-couple image containing light and the out-coupling optical element is configured to out-couple the image counting light towards a user, where the waveguide comprises an outer surface and an inner surface opposite to the outer surface, and wherein the inner surface is closer to the user than the outer surface; and a partially light blocking layer above the outer surface of the waveguide opposite to the user, where the partially light blocking layer is configured to keep eye glow light from entering the environment outside the outer surface of the waveguide.

Abstract: Disclosed herein is a head worn augmented reality display including a waveguide assembly including a first waveguide and a second waveguide; a first projector configured to output image containing light towards a first waveguide, where the image containing light is inputted into total internal reflection in the first waveguide and then outputted towards a user's first eye; a second projector configured to output image containing light towards a second waveguide, where the image containing light is inputted into total internal reflection in the second waveguide and then outputted towards a user's second eye. The first waveguide and the second waveguide are substantially transparent to light from the outside environment such that both the image containing light and light from the outside environment enters the user's eyes.
