Abstract :
The paper describes the design, construction and performance of a 1 m2, high-definition, wide-screen, multi-standard colour television projection display for use in laboratory studies of possible future television standards. Initially intended to operate on a 1249-line standard, it can now provide a number of scanning formats. A particular feature of the display is a `user-friendly¿ microprocessor-controlled digital convergence system, which enables the primary images to be registered everywhere within a fraction of a picture-element in only a few minutes.
