ABSTRACT:
A lighted display for a console, particularly for a telephone console for private branch exchanges, comprises a sandwich structure of a front transparent cover of a dark coloured material, an indicator layer or sheet of dark non-transparent material having transparent characters thereon and a plurality of lamps mounted in holders behind the indicator sheet, a lamp aligned with each character. When assembled an apparently completely dark blank display is presented, but on lighting of a lamp a clear distinct indication appears. Indication characters can be in vertical columns, and there is no need to stagger characters as occurs with conventional displays with "edge-lit" characters.
