ABSTRACT:
An incandescent display system suitable for use in displaying video images is disclosed. Incandescent lamps are positioned closely to each other in order to achieve a high resolution picture. The lamps are mounted in modules which can be removed from the rear of the display for periodic servicing. The modules include openings to permit cooling air to flow over the surface of the lamps and the display system enclosure is pressurized to create a constant flow of air for this purpose.
