INFORMATION DISPLAY (VARIANTS) Russian patent published in 2004 - IPC

FIELD: information displaying equipment. SUBSTANCE: proposed information display includes light source coming in the form of laser and deflector carrying first line of micromirrors positioned one after another horizontally and second line of micromirrors arranged vertically, parallel one another and perpendicular to micromirrors of first line. Micrcomirrors of first line are mounted for sequential inclination through 45 deg and micromirrors of second line are mounted for oscillation around their axis. Micromirrors present micro-electromechanical devices changing direction of light beam as result of electromagnetic, or piezoelectric, or electrostatic effect on them. According to first and second variants of information display light beam is injected from face part of first line of micromirrors. In correspondence with first variant each pair of micromirrors of first and second lines deflects light beam by 20-30 deg to implement frame scan. According to second variant each pair so deflects light beam that it is reflected from curved strips with mirror deposition arranged along plane of panel to carry out frame scan. In compliance with third variant coherent modulated light beam are injected from face parts of both lines of micromirrors so that luminous dot which is element of image is formed on their crossing. EFFECT: provision for high-frequency oscillation of micromirrors, enhanced strength and reliability of information display under sustained load. 3 cl, 12 dwg
