Abstract

Display comprising at least one translucent front panel, on which a text of a figure has been placed or printed, said text comprising at least one seven element digit, the elements of which comprise two differently coloured surfaces adapted to filling out alternately an aperture in the front panel, which elements are rotatable about a shaft running parallel to the front panel, and in which display means for lighting the back board of the front panel are placed. To provide a display lit from the interior, by means of which both the front panel and the movable parts of the digits are to appear as transilluminated areas essentially without shadows from the interior parts of the display, the means for lighting the front panel are placed at some distance from the front panel and in such a way that their perpendicular projection on the front panel falls outside the circumference of the seven element digit and in that the differently coloured surfaces of the digit elements are placed symmetrically around the shaft of an at least partially translucent carrier body at a distance corresponding essentially to the distance of the lighting means from the front panel.
