Abstract: A display apparatus and method are provided for at least partially compensating for undesirable image degradation arising from the processing of a generated image prior to display at a viewing surface, such as a combiner. The degradation is such that a viewer perceives a reduction in contrast ratio of a portion of the image content appearing in one or more regions of the field of view of the display, for example against an external scene being viewed through the combiner. In the invention, control means are provided to at least partially compensate for the reduction in contrast ratio by decreasing the resolution of the portion of the generated image content intended for display in the region of perceived reduced contrast ratio prior to input to the processing function.

Abstract: An optical waveguide (30) is provided having at least first and second diffraction regions, the first diffraction region being arranged to diffract image -bearing light propagating along the waveguide so as to expand it in a first dimension and to turn the image -bearing light towards the second diffraction region, the second diffraction region being arranged to diffract the image- bearing light so as to expand ii in a second dimension and to release it from the waveguide as a visible image. The first diffraction region is formed by first diffraction grating (14) embedded within the waveguide, arranged to present a substantially similar profile to the image -bearing light when incident upon the grating from a given angle above or below the grating.

Abstract: The present invention provides a projection display, for displaying an image to a viewer. An image-providing light source device is arranged to inject an input pupil of multi-spectral image bearing light into a waveguide assembly. The waveguide assembly comprises first and second diffraction regions arranged respectively for expanding the input pupil in first and second generally orthogonal dimensions and outputting an exit pupil expanded in the first and second dimensions from the waveguide assembly. The diffractive regions of the waveguide assembly are matched to cause zero or substantially zero net chromatic aberration. A combiner is arranged to direct the exit pupil towards the viewer for viewing an image and to transmit light from a real world scene through the combiner so that the image overlays the light from the real world scene.

Abstract: A display apparatus for displaying an image to a viewer 4, with an optical waveguide 8 arranged to receive image-bearing light 2 and to guide the received image-bearing light to an output 5. A combiner 70 is arranged next to the output part of the optical waveguide to reflect the image-bearing light output by the waveguide in a direction which passes back through the optical waveguide and for allowing light 6 from an external scene to pass through the combiner in the direction of and then through the optical waveguide to combine with the reflected image-bearing light so that both images are superimposed. The waveguide and combiner may be substantially planar and transmissive to the light from the outside. Preferably the combiner has a coating to reflect the image bearing light and transmit the external light. The waveguide may also have diffraction gratings on the input and output and be plate or rod-like.

Abstract: A display apparatus for use in displaying an image to a viewer (4), comprising an optical waveguide (8) arranged to receive image-bearing light (2) into the optical waveguide to guide the received image-bearing light therealong to an output part (5) of the optical waveguide for output therefrom. A combiner (70) is arranged adjacent to the output part of the optical waveguide for reflecting image-bearing light output by the waveguide in a direction which passes back through the optical waveguide and for allowing light (6) from an external scene to pass through the combiner in said direction through the optical waveguide to combine with the reflected image-bearing light so that the image-bearing light overlays light from the external scene for viewing by a viewer.

Abstract: The present invention provides a projection display (10), for displaying an image to a viewer (12). An image-providing light source device (60) is arranged to inject an input pupil (61) of multi-spectral image bearing light into a waveguide assembly (50). The waveguide assembly (50) comprises first and second diffraction regions arranged respectively for expanding the input pupil in first and second generally orthogonal dimensions and outputting an exit pupil (54) expanded in the first and second dimensions from the waveguide assembly (50). The diffractive regions of the waveguide assembly (50) are matched to cause zero or substantially zero net chromatic aberration. A combiner (16) is arranged to direct the exit pupil (54) towards theviewer (12) for viewing an image (18) and to transmit light (52) from a real world scene through the combiner (16) so that the image (18) overlays the light (52) from the real world scene.
