Anamorphic Near-Eye Display Device

A near-eye display apparatus comprising:

• a first illumination system comprising a first spatial light modulator and a first optical apparatus, wherein the first spatial light modulator is arranged to output light via the first optical apparatus to provide a first image for display, wherein the first optical apparatus has an optical axis and positive optical power in lateral and transverse directions that are perpendicular to each other and perpendicular to the optical axis, and wherein the first optical apparatus has anamorphic properties in the lateral and transverse directions;
• and
• a second illumination system comprising a second spatial light modulator and a second optical apparatus, wherein the second spatial light modulator is arranged to output light via the second optical apparatus to provide a second image for display, and wherein the second optical apparatus has positive optical power for the light output by the second spatial light modulator,
• wherein the first illumination system is arranged to receive, from the second illumination system, light corresponding to the second image and to permit the received light corresponding to the second image to pass therethrough for display, and
• wherein the first image provided by the first spatial light modulator and first optical apparatus has at least one property that is different to the second image provided by the second spatial light modulator and second optical apparatus,
• wherein said at least one property comprises at least one of:
• image resolution;
• image content;
• brightness;
• exit pupil size;
• modulation transfer function;
• field of view;
• focal plane distance;
• response speed;
• pixel arrangement;
• and
• colour gamut.
