摘要： A light-light transfer method using a spatial light modulator realizes an image display with a high utilizing of light without causing an undesirable residual image. The spatial light modulator is constituted to include two electrodes and at least a photoconductor layer member and a photo-modulation layer member used in a birefringence operating mode both being sandwiched between the two electrodes. A writing light is entered from the photoconductive layer member side so that its exposure value varies from the minimum exposure value to the maximum exposure value in a condition that a predetermined operation voltage is supplied between the two electrodes. In this instant, a voltage applied between both ends of the photo-modulation layer member corresponds to a voltage obtained by subtracting a voltage drop amount, occurring in the photoconductor layer member due to an incidence of the writing light, from said predetermined operation voltage applied in advance between said two electrodes. An operational condition of the spatial light modulator is set so that the voltage applied between both ends of the photo-modulation layer member becomes a voltage monotonously exceeding a voltage value corresponding to an extreme value of a degree of photo-modulation in a characteristic curve showing a relationship between an applied voltage and a degree of photo-modulation in the photo-modulation layer member, at the timing when the writing light of the maximum exposure value is entered into the spatial light modulator.

摘要： A clear color image having a high contrast ratio without particular coloration is displayed on a screen by improved display apparatus. Such display apparatus is comprised of a spatial light modulator including a photo-conductive layer, a photo-modulator layer and a dielectric mirror, a device for writing color images of different colors onto the spatial light modulator time-divisionally in a sequence of the different colors, a reading device for producing reading lights having different colors in synchronism with time-divisional writing of the color images, and for projecting the reading lights to the spatial light modulator, a driving device for supplying the spatial light modulator with different voltages and frequencies correspondingly with the reading light of different colors and in synchronism with time-divisional projections of the reading lights, and a device for projecting the color images read out from the spatial light modulator on the display device.The dielectric mirror may have a light absorbance characteristic controlled to be wavelength-selective to absorb a color of light to which the photo-conductive layer is most sensitive, so that lights having different colors leaked into the photo-conductive layer through the dielectric mirror are controlled to cause a uniform impedance of the photo-conductive layer.
