ABSTRACT:
A TV display, typically derived from a high-intensity miniature cathode ray tube (1) and available on a projection screen (8) thereof is enlarged by an optical lens system and, as enlarged, projected behind a viewing screen (10) via an optical folded system. The specific arrangement of the TV tube (1) and one or more deflection mirrors (3, 4, 5) forming the optical folded system towards the viewing screen (10) permit flat and light-weight construction of the projection system.
