A projection design configured for use with a projector having a projector
lens is provided. The device includes at least one pi-cell or pi-cell
electro-optical modulator in combination with a wire grid polarizer
mounted proximate the pi-cell(s). The design may include a cleanup
polarizer between the pi-cell(s) and the wire grid polarizer and
optionally a protective window between the wire grid projector and
projection lens. The device may be oriented at an angle substantially
differing from the axis of the projector lens. The resultant device
includes spacing for airflow and can offer improved performance,
particularly in heating, over designs previously available.
