Summary:A display device includes a display arrangement and an optical attenuator arrangement. The display arrangement has inherent non-uniformity of an output intensity across the display area. The optical attenuator arrangement is positioned in front of the display arrangement and in registration with the display area. The optical attenuator arrangement has a light attenuation characteristic that varies across the display area and is adapted to optically reduce the inherent non-uniformity of the output intensity.
