PROJECTION DEVICES USING MICRO LED PANEL AND METHOD FOR MANUFACTURING THIRD MICRO LED DISPLAY DEVICE AMONG PROJECTION DEVICES

摘要

PROBLEM TO BE SOLVED: To provide a projection device using a micro LED panel.;SOLUTION: A projection device includes: a first micro LED panel for outputting light of a first wavelength using micro LED pixels with a first wavelength; a second micro LED panel for outputting light of a second wavelength using micro LED pixels with the second wavelength; a third micro LED panel for outputting light of a third wavelength using the LED pixels of the first and second wavelengths; and a dichroic prism for synthesizing light output from the first to third micro LED panels, where the third micro LED panel includes a color conversion film for converting the light of the first or second wavelength to the light of the third wavelength.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
