Abstract:
1. A projecting device, comprising: a light source configured to emit lights; a filtering component configured to change the lights into substantially parallel polarized ultraviolet lights; a reflecting mirror configured to reflect the substantially parallel polarized ultraviolet lights; a digital micro-mirror device comprising a plurality of microscopic mirrors arranged in a rectangular array configured to be adjustable to reflect the substantially parallel polarized ultraviolet lights reflected by the reflecting mirror; a projecting lens configured to diverge the substantially parallel polarized ultraviolet lights; and a panel comprising a transparent substrate, a first fluorescence material layer, a second fluorescence material layer, and a third fluorescence material layer, wherein the first, second, and third fluorescence material layers are positioned on the transparent substrate and configured to be excited by diverged polarized ultraviolet lights and emit red, blue, and green lights.
