Abstract
A sequential color display system using a white light source (202) to create a full color image projected onto an image plane (214). A dynamic filter (206), typically a series of moving dichroic filters, generates a series of primary colored light beams that are swept across the surface of a spatial light modulator (210). Light rejected by the dynamic filter (206) enters a light recycler (204) and is reapplied to the dynamic filter (206). The light recycler is typically one or more reflective surfaces, including mirrors, baffles, enclosures, lamp reflectors, TIR surfaces, or specially coated material arranged in such a way as to encourage light toward an aperture separating the light recycler (204) and the dynamic filter (206). Typically all three primary colors are produced simultaneously by the dynamic filter (206). The illuminated portion of the dynamic filter (206) is imaged onto the modulator (210) and a controller (216) provides appropriate image data for each portion of the modulator (210) in synchronization with the sweep of the primary color bands across the modulator surface. The primary color bands are modulated by the spatial light modulator (210) and the modulated light is focused by lens (212) onto the image plane (214). The viewer integrates the light arriving at each portion of the image plane (214) over a frame period to provide the perception of a full-color image.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
