Head-up display

A display system enabling a user to view a light emitting display and an ambient environment simultaneously, the display comprising for each of the eyes of a user:

• a light-transmissive block allowing the transmission of light from the ambient environment to the user's eye through the block from a first surface to a second surface opposing said first surface;
• a light emitting display located on a third surface of the block, the third surface being substantially perpendicular to said first and second surfaces;
• a beam splitter having a plane surface arranged at substantially 45 degrees to said first and second surfaces, so as to reflect light from the light emitting display through the second surface;
• and
• a shutter located on said first surface, adapted to block, within a pre-defined area, the transmission of light from the ambient environment to the user's eye, for providing a dark background for the light emitting display, wherein the shutter is addressable for varying a level of light transmission into the light-transmissive block, having a plurality of addresses, wherein each address varies the level of light transmission according to a corresponding address of the light emitting display.

A display comprising:

• a light-transmissive block having a first surface and a second surface opposing said first surface;
• a light emitting display located on a third surface of the block, the third surface being substantially between the plane of the first surface and the plane of the second surface and perpendicular to said first and second surfaces;
• a beam splitter having a plane surface arranged at substantially 45 degrees to said first, said second surface, and said third surface for reflecting an image projected from the light emitting display to the second surface;
• and
• an addressable shutter of said first surface, for varying a level of light transmission into the light-transmissive block, having a plurality of addresses, wherein each address varies the level of light transmission according to a corresponding address of the light emitting display.
