20110164036 | AUTOSTEREOSCOPIC DISPLAY DEVICE - An autostereoscopic display device comprising a view forming module in registration with an image forming means. 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 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.
