The projector uses a high-power five-inch cathode ray tube and a magnifying  optical system capable of projecting images onto a specially-coated reflective screen four feet wide by three feet high but capable of going up to seven feet wide by five feet high.
        RCA has been working on large-screen television since 1928 and continues to do so for the next decade or more. In 1940 a 441-line system displaying a 20ft wide image is shown in New York and by 1945 the system has progressed to 525 lines.
