摘要： The color uniformity of a liquid crystal projector is improved by introducing phase lag plates. The light beam from a light source is first passed through a phase lag plate and only then through the liquid crystal element. In this manner, the phase lag plate introduces rotational polarization so that the S-polarized light is aligned throughout the entire beam front. Optionally, the image can be further improved by introducing a cold mirror to intercept the ultraviolet rays and a hot mirror to intercept the infrared rays.
