  • Antireflective coating
    Patent number: 8541860
    Abstract: Device and method for an antireflective coating to improve image quality in an image display system. A preferred embodiment comprises a first high refractive index layer overlying a reflective surface of an integrated circuit, a first low refractive index layer overlying the first high refractive index layer, a second high refractive index layer overlying the first low refractive index layer, and a second low refractive index layer overlying the second high refractive index layer. The alternating layers of high refractive index material and low refractive index material form an optical trap, allowing light to readily pass through in one direction, but not so easily in a reverse direction. The dual alternating layer topology improves the antireflective properties of the antireflective layer and permits a wide range of adjustments for manipulating reflectivity and color point.

  • Method for improving flat panel display anode plate phosphor efficiency
    Patent number: 5611719
    Abstract: A method of fabricating an anode plate 18 for use in a field emission device comprises the steps of providing a transparent substrate 20 and depositing a layer of a transparent, electrically conductive material 24 on a surface of the substrate. Next, portions of the layer of conductive material 24 are removed to form regions of the conductive material. Luminescent material 26 is then applied on the conductive regions and an outer portion 27 of at least some of the particles of the luminescent material are thereafter removed.
