Abstract

Provided is a color wheel. The color wheel includes a substrate, a conversion layer disposed on the substrate for wavelength conversion of incident light and obtaining irradiated laser, a first filter layer for filtering the irradiated laser to obtain a first light for modulating an image in a first color gamut range, and a second filter layer for filtering the irradiated laser to obtain a second light for modulating an image in a second color gamut range. Planes, in which the light incident surface of the conversion layer, the light incident surface of the first filter layer and the light incident surface of the second filter layer are located respectively, are parallel or coincide with each other.
