Abstract

The invention discloses an electronic price and information display, the color of which for the background and/or displayed symbols may be changed by means of additionally arranged filters, which are arranged to be rotated 90 DEG on top of the basic filter, to thereby change the color of the background and/or the symbols. The price and information displays being arranged with additional filters, according to the invention, may constitute LCD screens of either reflexive, transmissive or transreflexive type.
