Abstract
A color gamut conversion module, a conversion method thereof, and a projection device are provided. The color gamut conversion module includes a wavelength conversion element and a light filtering element. The wavelength conversion element includes at least two wavelength conversion regions, and the light filtering element includes at least one filtering region. Each filtering region is a single-band light filtering region or a multi-band light filtering region. In a visible light transmittance spectrum, the single-band light filtering region includes a band-pass wave band, and the multi-band light filtering region includes a plurality of first band-pass wave bands and a plurality of first cut-off wave bands. In a first color gamut mode, the wavelength conversion element and the light filtering element rotate at a first relative rate. In a second color gamut mode, the wavelength conversion element and the light filtering element rotate at a second relative rate.
