same area by the barrier. The control is effected by the real or apparent position of the electron source. Either a separate electron gun is used for each independent set of elements or the beam originating in a single electron gun may be successively shifted through the proper O points. Such cathode-ray tubes can be used in multitrace oscilloscopes giving each trace a different color, or as multicolor radarscope for differentiating by color such things as moving targets, radar beacons, etc. The most important application, however, appears to be for color television in two-, three or fourcolor sequential or simultaneous-type systems. A large number of tricolor picture tubes are being built on this principle.4'5-6 At present the application of the parallax barrier principle in a cathode-ray tube represents the most promising solution for an all-electronic color television viewing device.
