field-sequential color tv system
Noun: An early form of color television technology. In this system, the complete television picture (a frame) is created by displaying three successive fields, each scanned in a different primary color (red, green, and blue). The viewer's perception blends these rapidly displayed monochrome fields into a single full-color image.
