LIGHT-SPLITTING AND LIGHT-COMBINING PRISM AND PROJECTION DISPLAY SYSTEM

WIPO Patent Application WO/2021/190066

A1

Disclosed is a light-splitting and light-combining prism (100), comprising a housing (1) of a cube structure having six sides, with one side thereof serving as a light-combining output side or a light-splitting input side of the light-splitting and light-combining prism (100), and the other five sides thereof correspondingly serving as light-combining input sides or light-splitting output sides of the light-splitting and light-combining prism (100); and further comprising beam-splitting diaphragms (21, 22, 23, 24) arranged in the housing (1), wherein the beam-splitting diaphragms (21, 22, 23, 24) are configured for selectively transmitting or reflecting light beams incident to the light-splitting and light-combining prism (100); multiple light beams incident from the light-combining input side are reflected or transmitted by the beam-splitting diaphragms (21, 22, 23, 24) and are then emitted from the light-combining output side so as to realize light combining; and light beams incident from the light-splitting input side are reflected or transmitted by the beam-splitting diaphragms (21, 22, 23, 24) and are then emitted from the light-splitting output side so as to realize light splitting. The light-splitting and light-combining prism (100) can simultaneously realize light splitting or light combining of at most five light beams.
