Abstract:
1. A system for displaying a respective image in response to each frame of a field-sequential video signal, the system comprising: light sources of different primary colors; a light guide having a light input edge for receiving light of the different primary colors from the light sources and propagating the light in the light guide by total internal reflection; and an array of pixels that are opened and closed by a movable member that deforms under application of an electric field to frustrate the total internal reflection of propagated light in the light guide at defined locations on the light guide according to a predetermined shuttering sequence to output light of the different primary colors from the light guide consecutively in a time of less than 4 milliseconds during the frame of the video signal, and to output no light during the remainder of the frame, the pixels being operable to modulate the light of each primary color output from the light guide in at least one of intensity and pulse width.
