Abstract:
A display system comprising:a light source for providing beam of light along a light path, said beam of light periodically varying due to changes in polarity of an alternating drive current;a modulator array in said light path;a controller electrically connected to said modulator array, said controller operable to receive image data and to control said modulator array, said image data comprising multiple bits of image data for each element in said modulator array, said controller providing said bits of image data to said modulator array elements such that the total quantity of light directed by each modulator element to an image plane is proportional to the weight of said image data bit; andwherein a period of said periodically varying beam of light is less than 0.1 times a least significant bit period of said data signal.
