Abstract
A guiding-substrate display may include an angle-mapped display engine to generate a modulated photonic output having angle-mapped rays responsive to an electrical signal without the use of an ocular lens. An input optical element receives the modulated photonic output of the angle-mapped display engine and cooperates with the angle-mapped display engine to launch modulated photonic output having selected polarization. An image relay slab receives the modulated photonic output from the input optical element and guides the modulated photonic output from a proximal to a distal location. An output optical element to receives the modulated photonic output from the image relay slab and launches the modulated photonic output having angle-mapped rays toward a viewing region.
