Abstract
One embodiment provides an apparatus for displaying an image comprising: a first optical substrate comprising at least one waveguide layer configured to propagate light in a first direction, wherein the at least one waveguide layer of the first optical substrate comprises at least one grating lamina configured to extract the light from the first substrate along the first direction; and a second optical substrate comprising at least one waveguide layer configured to propagate the light in a second direction, wherein the at least one waveguide layer of the second optical substrate comprises at least one grating lamina configured to extract light from the second substrate along the second direction; and the at least one grating lamina of at least one of the first and second optical substrates comprises an SBG in a passive mode.
Description
[0001] related application [0002] This application is a continuation-in-part of U.S. Application No. 13 / 844456, filed March 15, 2013, which requires U.S. Provisional Application No. 61 / 796,632, filed November 16, 2012 and February 2013 Priority to US Provisional Application No. 61 / 849,853 filed on 4th, each of which is hereby incorporated by reference in its entirety. technical field [0003] This application relates to a transparent waveguide display device Background technique [0004] There is a need for a compact transparent data display device capable of displaying image content ranging from symbolic and alphanumeric arrays to high resolution pixelated images. Examples of transparent display devices include HMDs, HUDs, HDDs and others. In each case, an important element is that the display device should be highly transparent and the displayed image content should be clearly visible when placed on a bright background. The display device should provide full color wit...
