Title:
PROJECTION SYSTEM AND PROJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/033384
Kind Code:
A1
Abstract:
The embodiments of the present application provide a projection system and a projection device. The projection system comprises a light source (11), a spatial light modulator (12) and a displacement structure (13); the light source (11) is used for emitting display light; the spatial light modulator (12) is provided on a light path of the display light emitted from the light source (11), and the spatial light modulator (12) is used for modulating the display light emitted from the light source (11), so as to emit image light; the spatial light modulator (12) comprises a plurality of pixel units arranged in an array, each pixel unit comprising a plurality of sub-pixel units; and the displacement structure (13) is used for moving images displayed by the plurality of sub-pixel units of the spatial light modulator (12), so that in any image, each sub-pixel unit can display white light in space. The resolution of the spatial light modulator (12) can be improved without reducing the aperture ratio of the spatial light modulator (12), and the problem of color separation can be further avoided.
