Modular rear projection television having an airtight upper cabinet

摘要

One kind of housing has been formed for rear projection televisions of each screen size in inches and it has not been possible to change the size in inches for such a housing. This has reduced productivity and results in a cost increase. An upper cabinet and a lower cabinet of a rear projection television are formed separately. A screen and a mirror are provided on the upper cabinet. A main component portion for a television comprising video devices, driving and control circuits, an optical unit including a projection lens, and a light source is provided on the lower cabinet. Upper cabinets of different screen sizes in inches are assembled with a common lower cabinet to allow rear projection televisions of various sizes in inches to be easily manufactured.
