Abstract
A color-television receiver employing a single kinescope of the line-screen type has been developed. The kinescope screen consists of many hundred narrow parallel phosphor strips of the three primary colors, arranged cyclically. In the method investigated in greatest detail, the raster scanning lines are parallel to the phosphor strips. Circuit means are provided to cause the scanning lines to coincide with the phosphor strips of a single color. The beam is then deflected by a "stair-step" wave to the adjacent lines of the two remaining colors to generate color-dot areas in synchronism with the received color signal. The required registration of scanning lines with the screen elements is obtained by means of a servo circuit deriving control information from secondary-emission-signal areas on the kinescope screen. Various alternatives to this arrangement have also been investigated. Kinescopes of 16-inch envelope diameter have been employed to give color pictures of high horizontal definition and adequate color purity.Keywords
