Abstract: An illuminated display assembly fits into an opening in a display board such as a sports scoreboard. The display assembly includes an indicator module containing a front panel having a plurality of light transmitting data indicating areas arranged thereon with a plurality of chambers mounted behind the front panel. Each chamber is associated with one of the data indicating areas and encloses light sources therein which illuminate the data indicating areas when energized. A light source module includes a printed circuit board having a plurality of light sources mounted thereto. When the light source module and indicator modules are assembled together, the light sources from the former project into the chambers in the latter to form a finished display.
