Patent ID: 7703925

Claim:
A miniature projector module comprising: a light source unit capable of emitting source light with first and second polarizations; a polarization beam splitter capable of reflecting the source light with the first polarization, and permitting transmission of the source light with the second polarization therethrough; a first image modulator capable of converting the source light with the first polarization reflected by said polarization beam splitter into image light with the second polarization, and directing the image light with the second polarization toward said polarization beam splitter for further transmission therethrough; a second image modulator capable of converting the source light with the second polarization transmitted through said polarization beam splitter into image light with the first polarization, and directing the image light with the first polarization toward said polarization beam splitter for further reflection thereby; a projector lens disposed to receive and project the image light with the first and second polarizations from said polarization beam splitter; and a mounting seat that includes a light-entry side having said light source unit mounted thereto, a light-exit side having said projector lens mounted thereto, and first and second light-receiving sides having said first and second image modulators mounted thereto, respectively, said polarization beam splitter being disposed between said light-incident side and one of said first and second light-receiving sides.
