Latest Patents

Van Gelder holds a patent for a "Color video projection display system with low-retardance compensator film for improved contrast." This invention focuses on a color video projection display system that boasts an improved contrast ratio. The system utilizes at least one reflective or transmissive panel, such as a liquid crystal on silicon (LCoS) panel, which receives incident light of designated colors through an input optical path. The panel modulates the incident light based on applied signals, and the modulated light is processed through an output optical path to create a viewable display. A key feature of this invention is the inclusion of a low-retardance film positioned within the optical paths to enhance the contrast ratio of the display. This technology can be implemented in both single-panel and multi-panel configurations.
