Abstract
A method for fabricating a monolithic color wheel. The method includes (a) preparing a square transparent substrate; (b) forming a plurality of color filters on the square transparent substrate; and (c) cutting the square transparent substrate and the color filters together along a circular path, to form a color filter disk. Through these steps, a color filter disk of color wheel can be produced with better dynamic equilibrium quality, and will run more quietly and smoothly.
