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