Abstract
A display device has a display, operable to generate a real image, and an optical system, comprising one or more lenslets, arranged to generate a virtual sub-image from a partial real image on the display, by each lenslet projecting light from the display to an eye position. The sub-images combine to form a virtual image viewable from the eye position. At least one lenslet is symmetric with respect to a plane, and the display surface is cylindrical with its axis perpendicular to that plane.

A display device comprising:
- a display, operable to generate a real image;
- and
- an optical system, comprising one or more lenslets, arranged to generate a virtual sub-image from a respective partial real image on the display, by each lenslet projecting light from the display to an eye position;
- wherein the sub-images combine to form a virtual image viewable from the eye position;
- wherein at least one said lenslet is symmetric with respect to a plane and the display surface is cylindrical with its axis perpendicular to said plane.

A display device comprising:
- a display, operable to generate a real image;
- and
- an optical system comprising a plurality of lenslets each arranged to generate a virtual sub-image from a respective partial real image on the display, by each lenslet projecting light from the display to an eye position;
- wherein the virtual sub-images combine to form a virtual image viewable from the eye position;
- wherein each lenslet comprises first and second freeform optical lenses so arranged that light from the display passes through both the first freeform optical lens and the second freeform optical lens to the eye position.
