LIQUID CRYSTAL PROJECTION SYSTEM

摘要

PURPOSE: A liquid crystal projection system is provided to correct pictures focused in deformed and/or curved states due to the aberrations of optical lenses by deforming the structure of a flat projector. CONSTITUTION: A liquid crystal projection system comprises a light source(410), a scrambler(430), a polarized beam splitter(440), a LCD(450) and a projection lens unit(460). The scrambler(430) mixes incident lights from the light source to generate a homogeneous beam. The splitter(440) has a focus lens(431) and a collimator lens(432) and changes optical paths in accordance with the polarized components of the incident light. The LCD(450) selectively reflects the incident lights to generate pictures. The projection lens unit(460) expands and projects the incident lights on a screen(S).
