Abstract: A directional illuminator includes a light source, a pupil-replicating lightguide, and a tiltable reflector coupling the light source to the pupil-replicating lightguide. The exit beam angle of the light outputted by the pupil-replicating lightguide follows the in-coupling angle, and accordingly depends on the tilting angle of the tiltable reflector. The directional illuminator with steered light beam may be used to illuminate a display panel. Steering the illuminating light by the tiltable reflector enables one to steer the exit pupil of the display device to match the user's eye location(s).

Abstract: A display device includes an optical diffuser configured to, in response to receiving image light, output diffused image light having a same polarization as the image light. The optical diffuser is also configured to transmit ambient light. The display device also includes an optical assembly that includes a substrate, a reflector coupled to the substrate, and a beam splitter coupled to the substrate. The optical assembly is configured to transmit the diffused image light at a first optical power by reflecting the diffused image light at the reflector and at the beam splitter and to transmit the transmitted ambient light at a second optical power that is less than the first optical power without reflection at the reflector or the beam splitter. A method for transmitting light through the display device is also disclosed.

Abstract: A see-through illuminator for a reflective display panel provides a better image contrast when the illuminator is configured to direct a leakage light beam exiting the lightguide from a side opposing the display panel to propagate non-parallel to an image light formed by reflection of an illuminating light beam from the display panel. An objective lens may concentrate the image and leakage light beams at different locations, enabling a user's eye placed at a location of the image light beam to see the projected image without interference from the leakage light beam.

The SLM is configured to receive and modulate the portion of the illumination light transmitted through the optical assembly, and to output the modulated light. A method performed by the display device is also disclosed.
