摘要： A micro-mirror light modulator and associated projection display system. The projection display system includes a light source, a linear light source illumination system that transforms a light emitted from the light source into a thin linear light, a micro-mirror light modulator that selectively diverts the direction of the incident thin linear light to create reflected light, a light transmitting layer that selectively transmits or filters out the reflected light, a condenser lens that focuses the light transmitted by the light transmitting layer, and a scanner that scans the focused light such that the light forms a projected image. The micro-mirror light modulator includes a reflection electrode that deflects toward an electrode when a voltage is applied. The reflection electrode reflects light depending on its deflection state. The micro-mirror light modulator is driven by low voltage, is easily fabricated such that the cost is reduced, and exhibits enhanced image contrast.

摘要： A projection display system in which light use efficiency and image brightness are enhanced by collecting and using substantially all of the light that has been diffracted from a diffractive linear display device without loss of higher-order modes of diffracted light. The projection display system includes a light source, a linear light illumination system that transforms light emitted from the light source into a thin linear light, a diffractive linear display device that modulates the luminous intensity of the thin linear light by selectively diffracting the thin linear light, a mode selection optical system that selectively transmits or filters out the light diffracted by the diffractive linear display device according to the order of the diffracted light, a scanner that scans a linear image projected from the mode selection optical system, and a projection lens that enlarges and projects the image onto a screen.
