PROJECTION SYSTEM USING A SCREEN INCLUDING QUANTUM DOTS, WHICH FORMS AN IMAGE ON A SCREEN BY THE LIGHT OF A PROJECTOR

摘要

PURPOSE: A projection system using a screen including quantum dots is provided to prevent the decrease of luminous efficiency which generated when green lights are directly projected from a projector.;CONSTITUTION: A projection system using a screen including quantum dots comprises a screen(2) and a projector(4). A plurality of quantum dot(6) is dispersed on the surface of the screen. The projector is composed of a plurality of semiconductor lasers projecting light on the screen. The semiconductor laser projects red, blue and ultraviolet laser beam. The quantum dot changes ultraviolet lay into green wavelength.;COPYRIGHT KIPO 2011
