Zusammenfassung:	Methods and apparatus are provided for reducing the visual artifacts exhibited by a display employing individually addressable pixels. The apparatus comprises an array of pixels, each pixel having a switchable region of alterable transparency or luminance and a non-switchable region. The switchable region of each pixel is distributed, that is, divided into at least two simultaneously switched portions at least partly separated by a significant portion of the non-switchable region. The first order spatial harmonics and visual artifacts are significantly reduced. For a color display, each color pixel is similarly subdivided.
