Abstract
Abstract The invention relates to stereoscopic display means comprising; a) a plurality of discrete and independently controllable light sources (4) arranged on a surface (6), and, b) one or more light modifying elements (3) disposed in fixed relation to the surface (6) so as to enable the formation of a three dimensional image. The invention enables the formation of a moving stereoscopic display which can be viewed by the naked eye.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
49 words
1) A stereoscopic display means characterised by, a plurality of discrete and independently controllable light sources (4) arranged on a surface (6), and one or more light modifying elements (3) disposed in fixed relation to the surface (6) so as to enable the formation of a three dimensional image.
Claim 2
Dependent Claim
49 words
1) A stereoscopic display means characterised by, a plurality of discrete and independently controllable light sources (4) arranged on a surface (6), and one or more light modifying elements (3) disposed in fixed relation to the surface (6) so as to enable the formation of a three dimensional image.
Claim 3
Dependent Claim
48 words
2 ) Display means as claimed in claim 1, further characterised in that the plurality of light sources (4) are adapted and arranged for the display of a pair of interlaced images and the said three dimensional image comprises a pair of spaced apart images having parallax therebetween.
Claim 4
Dependent Claim
37 words
