Latest Patents
One of her latest patents is titled "High contrast projection." This invention presents a method and system for improving the contrast ratio of a projected image. An asymmetric aperture stop is utilized to enhance the contrast ratio by allowing the majority of the on-state projection light from the modulator array to pass through a region that is not centered in the projection lens pupil. This innovative approach effectively blocks a significant portion of the diffracted light while maintaining the desired projection light, resulting in darker dark regions and consistent light regions in the image.
Another notable patent is for the "Reduction or moiré effect in pixelated rear-projection displays." This invention provides an apparatus and method for reducing the moiré effect in rear-projection displays by rotating the dark-stripe structure in the screen by 45±15 degrees relative to the displayed pixel structure. This rotation improves the spatial frequency at which the moiré effect sets in by 15% to 41%, enhancing the overall viewing experience.
