ABSTRACT:
A projection apparatus arranged such that the first light source, the second light source and the third light source provide the first colored light, the second colored light and the third colored light, respectively. The first digital micromirror device (DMD) modulates and reflects the first colored light, while the second DMD modulates and reflects the second and third colored lights guided by the first light guiding device. Subsequently, the second light guiding device guides the colored lights reflected from the first DMD and the second DMD to the projection lens.
