Lcos panel assembly of projection system and image matching method thereof

摘要

A LCOS panel assembly of a projection system comprises: a LCOS panel; a panel support supporting the LCOS panel and coupled to a side of a polarizing beam splitter cube; a quarter-wave plate provided at the front side of the LCOS panel to polarize light; a quarter-wave plate holder rotatably supported about the panel support at a state where the quarter-wave plate is coupled thereto; and adhesives interposed on a contact surface of the quarter-wave plate holder and the panel support. Foreign substances are thereby prevented from being injected in an optical path of the LCOS panel assembly of the projection system, and deterioration of image matching is prevented.
