Abstract
Waveguides and waveguide displays having a layer for blocking non-image light (i.e. haze) that could otherwise reduce contrast and degrade color gamut and uniformity, while providing high transmission to external light are provided. Many waveguides and displays incorporate at least one light control layer applied to at least one external surface of a waveguide supporting at least one grating and overlapping at least a portion of the at least one grating, to divert or block scattered light from the set of gratings that might otherwise enter said eyebox.
