Altering surface of display screen from matt to optically smooth

摘要

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.
