Abstract:
1. A display system, comprising: a single liquid crystal spatial light modulator (SLM) having an array of pixels, each of the pixels in the array being switchable between a plurality of optical states in response to electrical drive signals provided to electrodes of the pixels by active components of the pixels, the active components of the pixels including transistors formed as integrated circuits in a semiconductor substrate of the SLM, the SLM accepting an input video signal that includes periodic frames of image data; and a light source that illuminates the pixels of the SLM, during each video signal period, with light of a first color during a first color subperiod and with light of a second color during a second color subperiod, at least one of the first color subperiod and the second color subperiod being shorter than 5.56 milliseconds; wherein the display system produces color gray-scale images corresponding to the input video signal, and wherein the light source illuminates the pixels of the SLM during at least a portion of the times that the electrical drive signals are causing the optical states of the pixels to switch.
