Abstract
The present invention offers a display system for displaying information comprising a linear array of N light-emitting devices emitting light of predetermined wavelength, the devices are arranged respectively with N pixels, a stream of the information is divided into pieces each of which containing the N pixels, and the N light-emitting devices are caused to emit N light beams simultaneously in a form of array during a given period for every divided piece of the information, the every divided piece of information may correspond to one line of a frame of picture, the N light beams are intensity-modulated respectively with the divided piece of the information, the N light beams are deflected simultaneously in a direction perpendicular to a direction of the array of the N light beams, and a spatial light modulator having a photoconductive layer and a light modulation layer interposed between a pair of electrodes, the photoconductive layer is responsive to the deflected N light beams incident thereto through a focusing lens as a writing light, and a reading light of visible wavelength which is shorter than the predetermined wavelength of the emitted light from the linear array of the N light-emitting devices, the reading light irradiates the photomodulation layer of the spatial light modulator to read out and display the written information thereon.
