Claim 0:
1. An optical engine module configured to receive an illuminating beam, wherein the illuminating beam comprises a first illuminating beam with a first linear polarization state and a second illuminating beam with a second linear polarization state, and the optical engine module comprises a first polarization beam splitting element, a first phase retardation element, a first light valve, a second polarization beam splitting element, a second phase retardation element and a second light valve, wherein
the first polarization beam splitting element is disposed on a transmission path of the illuminating beam and is configured to reflect the first illuminating beam to the first phase retardation element;
the first polarization beam splitting element is configured to allow the second illuminating beam to pass through and to be transmitted to the second polarization beam splitting element;
the first phase retardation element is disposed on a transmission path of the first illuminating beam, and the first illuminating beam passes through the first phase retardation element and is transmitted to the first light valve;
the second polarization beam splitting element is disposed on a transmission path of the second illuminating beam and is configured to reflect the second illuminating beam to the second phase retardation element;
the second phase retardation element is disposed on the transmission path of the second illuminating beam, and the second illuminating beam passes through the second phase retardation element and is transmitted to the second light valve;
the first light valve is disposed on the transmission path of the first illuminating beam and is configured to convert the first illuminating beam into a first image beam, wherein the first image beam from the first light valve passes through the first phase retardation element and is converted into the first image beam with the second linear polarization state, and then the first image beam with the second linear polarization state passes through the first polarization beam splitting element; and
the second light valve is disposed on the transmission path of the second illuminating beam and is configured to convert the second illuminating beam into a second image beam, wherein the second image beam from the second light valve passes through the second phase retardation element and is converted into the second image beam with the first linear polarization state, and then the second image beam with the first linear polarization state passes through the second polarization beam splitting element.
