Title:
PROJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/159545
Kind Code:
A1
Abstract:
A projection device, comprising: a light source assembly (10); a polarizing assembly (20) , which is provided on a light-emitting side of the light source assembly (10) and used for converting light emitted by the light source assembly (10) into first polarized light in a first polarization direction; a display panel (30), which is provided on the side of the polarizing assembly (20) away from the light source assembly (10) and used for adjusting a polarization direction of the first polarized light, so as to emit second polarized light, the polarization direction of the second polarized light being between the first polarization direction and the second polarization direction, and the first polarization direction being perpendicular to the second polarization direction; a reflective assembly (40), which is provided on the side of the display panel (30) away from the polarizing assembly (20) and used for reflecting one of the polarized light in the first polarization direction and the polarized light in the second polarization direction; and a projection lens (50), a light incident surface of which faces the reflective assembly (40), so as to receive light reflected by the reflective assembly (40).
