Title: Innovations of Joseph M. Haggerty in Liquid Crystal Technology
Introduction
Joseph M. Haggerty is an inventor based in Fallbrook, California, renowned for his contributions to the field of liquid crystal technology. With a focused expertise, he holds one patent that showcases a significant advancement in projector technology.
Latest Patents
Haggerty's patent is for a liquid crystal light valve projector designed with an improved contrast ratio. His invention features a quarter-wave compensator plate strategically placed between a polarization plate and a liquid crystal light valve. This compensator plate mitigates polarization irregularities caused by off-incident reflections within the projection light cone. By reversing the phase of the P component of the illumination light by 180 degrees, it effectively eliminates P-polarization leakage during the dark state of the liquid crystal light valve projector. Furthermore, Haggerty's innovation incorporates a heat shield and a substrate with low stress-optical coefficients to lower the birefringence of the liquid crystal light valve, thereby minimizing unwanted P-polarized light leakage onto the projection screen.
