An optical system for a liquid crystal on silicon (LCoS) projector includes a light emitting diode (LED) array, a light guide plate (LGP), and a polarization cube beam splitter (PBS). The LED array emits a beam of light. The LGP and the PBS are arranged along the optical path of the beam of light. The LGP includes an incident surface directly facing the LED array, an emitting surface, and an array of microstructures formed on the emitting surface. The PBS includes a side surface directly facing the emitting surface and an array of collimator lenses formed on the side surface. The microstructures are positioned at a focal surface of the collimator lenses.
