Title: Innovations of Donald D. Boswell
Introduction
Donald D. Boswell is a notable inventor based in Granada Hills, California. He has made significant contributions to the field of electro-optical systems, holding a total of five patents. His work primarily focuses on high brightness projection systems and methods to enhance image quality.
Latest Patents
One of Boswell's latest patents is for a high brightness full color image light valve projection system. This innovative system allows for the real-time projection of very high brightness, full color images from various program sources onto large display screens. The system utilizes three reflection-type AC driven field effect mode birefringent liquid crystal light valves, each modulating a primary color component of the video image. This design ensures that none of the optical elements absorb light, maintaining high brightness without overheating. The light valves reflect projection light from a high power source while modulating video images from a low-level light source. The optical system efficiently combines the three primary colors to create a full color image on the screen.
Another significant patent by Boswell is a method and apparatus for increasing the contrast ratio of stored images using cholesteric-nematic light valves. This method enhances the contrast ratio by applying a low amplitude voltage across the cell at an erasing frequency, which increases light scattering in stored image areas while decreasing it in clear areas.
