Segmented polarization split elements replace narrow-pitch converters, reducing projector size while maintaining high luminance.
A diffuser scatters LED light to reduce preferential emission intensity, resolving the trade-off between uniform brightness and aesthetic filament appearance.
Diamond scattering particles in a reflective screen enhance image brightness and contrast under bright outdoor illumination.
A projector light source device uses a segmented diffusion element to distribute partial light beams evenly across multiple areas.
