Abstract
A projection apparatus including: a light source component; a light polarization component for converting light from the light source component into first polarized light in a first polarization direction; a display panel on a side, away from the light source component, of the light polarization component for adjusting the polarization direction of the first polarized light to emit second polarized light in a polarization direction between the first polarization direction and a second polarization direction, the first polarization direction is perpendicular to the second polarization direction; a light reflective component on a side, away from the light polarization component, of the display panel for reflecting one of the polarized light in the first polarization direction and the polarized light in the second polarization direction; a projection lens, a light incident surface of which faces the light reflective component so as to receive light reflected by the light reflective component.
