  • Patent number: 9706180
    Abstract: An optical modulator element modulates incident light from a light source with an input signal. A projection lens magnifies and projects the outgoing light from the optical modulator element. A pixel shift element is disposed between the optical modulator element and the projection lens, and displaces an optical path of the outgoing light from the optical modulator element for shifting a display position of a pixel to be displayed on a screen in a given cycle between a first position and a second position away from the first position by a predetermined distance. A controller controls the pixel shift element such that the pixel shifts between the first position and the second position in either one of a first mode at a shift speed or a second mode at another second shift speed.
