Abstract

The publicity display permits the creation of luminous publicity panels whose colours change at will. The display has behind each letter a chamber (1). In the chamber is located in the form of a triangle as many red, blue and green lights (5) as the surface area permits. The space between them being sufficient to permit by additive synthesis the formation of the colour. Each face of the letter image (2) is made from an opaque plastic material. In the case of letters in relief, these can be surrounded by a non transparent material forming a reflector for the coloured rays. To obtain the colour range desired it is necessary that each lamb is connected with the variable rheostat. This rheostat permits a control of the colour min.
