Abstract
Disclosed herein is a pixel unit scanning-based display apparatus, in which diffracted beams having a plurality of diffraction orders, formed from a single beam through diffraction, are used to display images in such a manner that each pixel can form a plurality of dots on a screen by vibrating the diffracted light generated in pixels.
Claims8
A pixel unit scanning-based display apparatus, comprising:
- an illumination lens unit for scanning a single light beam incident from a light source unit, in a horizontal direction with respect to an optical path of the light beam;
- a diffractive optical modulator, provided with a plurality of pixels for forming a plurality of dots on a screen, for modulating the single light beam emergent from the illumination lens unit to form diffracted light having a plurality of diffraction orders;
- a filter unit for selectively passing a predetermined diffracted light beam, having a predetermined diffraction order, therethrough, said predetermined diffracted light beam being selected from among the diffracted light beams formed in the optical modulator;
- and
- a pixel unit scanning unit for displaying the diffracted light emergent from the filter unit to form a plurality of dots on a screen in such a manner that a dot is spaced apart from an adjacent dot by a predetermined distance that is sufficient to dispose a plurality of dots therein, and for scanning the diffracted light by pixel unit to display images.
