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.

A method for fabricating a monolithic color wheel, comprising the steps of:
- preparing a monolithic transparent substrate,
- adding a plurality of color filtering thin films on the transparent substrate;
- and
- cutting the transparent substrate and the filtering thin films together to form a circular filter disk;
- and
- connecting the filter disk to a motor.
A monolithic color wheel, comprising:
- a motor having a shaft;
- and
- a filter disk having a single piece of substrate and a plurality of filtering films connected on the single piece of substrate, wherein said filter disk is connected to the motor shaft;
- wherein the filter disk is cut from the single piece of substrate and the plurality of color filtering thin films together along a circular path.
A monolithic color wheel, comprising:
- a motor having a shaft;
- and
- a metal ring connected to the motor shaft to be driven by the motor;
- and
- a filter disk connected to the metal ring, wherein the filter disk has a single piece of substrate and a plurality of color filtering thin films which are added on the single piece of substrate;
- wherein the filter disk is cut from the plurality of color filtering thin films and the single piece of substrate along a round path.
