The RCA 3-gun shadow-mask color kinescope

IT HAS long been apparent that the ideal reproducer for color television should consist of a single kinescope capable of displaying the color picture directly. Considerable interest in the problem has resulted in quite a number of proposals for single-tube color kinescopes, and much time and effort has been expended in experimental work. No systematic review of the literature will be given nor will a description of the operating principles of the various kinds of proposed tubes be undertaken, for an article covering these subjects has recently been published.1 Rather, it is the purpose of this paper to give an over-all description of the Radio Corporation of America (RCA) 3-gun shadow-mask color tube including its construction and operating characteristics.
