The display combines an ordinary monochrome electronic visual display with a two-primary field-sequential display (FSD). This hybrid system provides full color, high spatial resolution, and high luminance. The FSD provides two of the three color primaries (i.e., red, green, and blue) using temporally separate color fields which alternate at twice the frame rate (e.g., 120 Hz). Its image is superimposed with the monochrome display's, which refreshes at a conventional frame rate (e.g., 60 Hz) and provides the third primary, thus yielding a full-color image. In this way, a full-color FSD is obtained without requiring the presentation of color fields at triple the frame rate (e.g., 180 Hz) or diminishing the FSD's luminous efficiency or color range. The system's maximum obtainable luminance is increased still further because the monochrome display's image does not timeshare with the other two primaries.
