The term "field-sequential color television system" refers to a technology for producing color TV images, where colors are displayed one after the other in rapid succession in each frame. Some synonyms for this technology include "sequential color television", "color scan television", "sequential color display", "field-sequential color display", and "sequential color scanning". These terms all describe the same process for producing color images on a TV screen based on the sequential display of primary colors. While this technology was once widely used, it has now been largely replaced by other, more efficient color processing methods. However, it remains an interesting milestone in the history of television and color display technology.
