Abstract: A functional film includes a transition layer having a first constituent and a second constituent having gradual content gradients according to a thickness of the functional film. The first constituent is at least one dielectric material selected from the group consisting of SiOx (x>1), MgF2, CaF2, Al2O3, SnO2, In2O3 and ITO, and the second constituent is at least one material selected from the group consisting of iron (Fe), cobalt (Co), titanium (Ti), vanadium (V), aluminium (Al), silver (Ag), silicon (Si), germanium (Ge), yttrium (Y), zinc (Zn), zirconium (Zr), tungsten (W) and tantalum (Ta).

Abstract: A photolithography method includes applying to a substrate a coating of a film forming composition containing a bonding resin and a film forming material and drying to form a film; selectively coating the film with a photosensitive composition including a photosensitizer to form a film pattern; exposing the film with the film pattern; and developing the film. Therefore, a film in a pattern and having excellent characteristics can be manufactured easily and efficiently. The photolithography method can be applied to any product which requires the formation of a film in a pattern.

Abstract: Phosphor coated with wide bandgap metal oxide which can be used for a plasma display panel (PDP) has a surface that is coated with a continuous, thin film of wide bandgap metal oxide. In preparing the phosphor coated with wide bandgap metal oxide, a pH of the wide bandgap metal oxide precursor solution containing an organic solvent and water is adjusted to 0.1-10 and heated under a reflux, thereby obtaining a metal hydroxide gel. The wide bandgap metal hydroxide gel is made to contact a phosphor for a PDP, thereby obtaining the gel-coated phosphor. The gel-coated phosphor is then dried and sintered.

Abstract: A method of manufacturing a phosphor screen for a flickerless cathode ray tube comprising the steps of forming red and green phosphor layers on a panel for a cathode ray tube on which a black matrix is formed, forming a blue phosphor layer on said panel on which a black matrix is formed by coating the blue phosphor slurry and drying and forming a double phosphor layer by coating an ultraviolet phosphor slurry on said blue phosphor layer and drying, is provided.

Abstract: An improved red, green or blue phosphor complex produced by adhering chromium compound on the red, green or blue phosphor using a polymer binder or an inorganic binder, or without a binder, has high brightness without changing the characteristics of the phosphor

Abstract: Disclosed is a ferroelectric liquid crystal display projector employing a fluorescent screen, including a light source emitting light of a predetermined wavelength; a first condensing lens for converting the light radiated from the light source into beams; a polarizing beam splitter for selecting a predetermined directional light in the incident light passing through the first condensing lens and for polarizing the light; a ferroelectric liquid crystal shutter on/off operated according to the polarizing operation of the polarizing beam splitter, the ferroelectric liquid crystal shutter comprising a reflecting layer attached on a backside and RAM devices attached on each pixel of a ferroelectric liquid crystal (FLC); an optical system for magnifying, at a predetermined ratio, the light reflected from the ferroelectric liquid crystal shutter; and a fluorescent screen of a fluorescent material which radiates by light, passing through the optical system, at a predetermined wavelength.
