Abstract
A matt surface (7) of a display screen (2) is converted to a non-diffuse optically smooth surface (11). The matt surface may be a diffusive surface (7) formed on a birefringent film (6) of an LCD screen (2). The display screen (2) is the front screen of a multilevel three dimensional display comprising layered screens (2, 3). The conversion from matt to non-diffuse and optically smooth surface reduces the blurring of displayed images.
