  • Optical microcavity for a high-contrast display
    Patent number: 10073293
    Abstract: An optical microcavity for a high-contrast display comprises an enclosed cavity having a front wall and a back wall, where the front wall comprises a pinhole opening for emission of light from the cavity and the back wall is configured to generate or transmit light into the cavity. An outer surface of the front wall absorbs some or substantially all optical wavelengths of externally incident light so as to appear black or colored. An inner surface of the front wall comprises a light reflectivity of greater than 90% to promote photon recycling within the cavity and light emission through the pinhole opening.
