The image forming means has an orthogonal array of display pixels spatially defined by an opaque matrix. The view forming module provides at least two optical functions, namely a view forming function and a brightness non-uniformity reducing function. The view forming function modifies the direction of outputs of the display pixels such that the outputs of groups of the display pixels are projected in respective different directions as a plurality of views. The view forming function is provided by an array of parallel lenticular lenses arranged across the view forming module and having a first pitch. The brightness non-uniformity reducing function spreads the outputs of the display pixels such that brightness non-uniformities caused by imaging of the opaque matrix are reduced. The brightness non-uniformity reducing function defines a second pitch across the view forming module less than the first pitch, and further defines an effective spreading angle in a plane perpendicular to axes of the view forming elements substantially equal to or less than the angle between adjacent views projected by the view forming function. The brightness non-uniformity reducing function is provided by an array of lenses or a diffuser. In the case of an array of lenses, these lenses may be integrated with the lenticular lenses providing the view forming function in the form of lenses having a polygonal cross section. | 07-07-2011 |
