OPTICAL MODULE, NEAR-EYE DISPLAY DEVICE, AND LIGHT PROJECTION METHOD

The present invention provides an optical module comprising: a partial-transmitting and partial-reflective layer, receiving circularly polarized light or elliptically polarized light; a second phase delay unit, located downstream of an optical path of the partial-transmitting and partial-reflective layer so as to receive and modulate the transmitting circularly polarized light or elliptically polarized light and then perform emission; and a polarized beam splitter, disposed downstream of an optical path of the second phase delay unit, the polarized beam splitter having a light transmission axis, wherein the optical module further comprises a second phase compensation unit located between the second phase delay unit and the polarized beam splitter, and wherein an optical axis of the second phase compensation unit is located in a plane orthogonal to the light transmission axis of the polarized beam splitter, or in a plane orthogonal to a light reflection axis of the polarized beam splitter. With an optical module of one example of the present invention, the occurrence of light leakage in a folded optical path can be reduced, and especially light leakage in a folded optical path can be reduced or eliminated in a large-angle range according to some preferred examples, thereby helping to improve the effect felt by a user.
