Resonant structure-based display
View Patent ↗A display of wavelength elements can be produced from resonant structures that emit light (and other electromagnetic radiation having a dominant frequency higher than that of microwave) when exposed to a beam of charged particles, such as electrons from an electron beam. An exemplary display with three wavelengths per pixel utilizes three resonant structures per pixel. The spacings and lengths of the fingers of the resonant structures control the light emitted from the wavelength elements. Alternatively, multiple resonant structures per wavelength can be used as well.
1. In a display, the improvement comprising:
plural pixels each having at least one resonant structure per pixel, wherein the resonant structure is excited by a charged particle beam to produce electromagnetic radiation having a dominant frequency higher than that of a microwave, the resonant structure being formed of segments of resonating material having at least one spacing therebetween.
