Abstract:
A near eye display comprising: a display device; and a waveguide; wherein the waveguide comprises an entry diffractive element and an exit diffractive element; wherein the display device is arranged to direct light into the waveguide via the entry diffractive element and wherein the exit diffractive element is arranged to direct light from the waveguide towards a user's eye; wherein the display device is arranged to output images in a repeating sequence of two or more different colours. Providing the images are transmitted in sufficiently quick succession, the brain will not perceive them as separate images, but will instead essentially merge them (as if they were overlaid on top of one another. As the brain is good at pattern recognition, it can compensate for any minor misalignments that occur between the different images. In this way the time-multiplexing approach avoids the need for multiple parallel waveguides for each specific colour or colour band.

Claim (Index 18):
A variable focus lens as claimed in  claim 17 , wherein the variable focus lens is a fluid filled lens.
