1. A color wheel module, comprising a disk, an isolation framework, an assembly member, a wavelength conversion layer, and a colloidal filler, wherein
the disk is configured to rotate around an axis,
the isolation framework and the assembly member are disposed on the disk,
the isolation framework is located between the disk and the assembly member, wherein an air layer is formed between the disk, the assembly member and the isolation framework, and
the colloidal filler is disposed on the assembly member;
wherein the disk has an optical wavelength conversion region, the wavelength conversion layer is disposed on the optical wavelength conversion region, and an orthographic projection of the isolation framework and an orthographic projection of the wavelength conversion layer on the disk do not overlap with each other.
