ABSTRACT:
The display has a mask positioned in front of it so that an opaque part of the mask prevents viewing the display. There may be several masks for different parts of the display. The masks are preferably in the form of tapes having opaque and transparent areas. The tape-masks are intermittently and/or sequentially moved to progressively reveal the display. The display may consist of one or more lines of pictorial, textual, or three-dimensional matter.
