Abstract:
Die Erfindung sieht ein Verfahren zur Herstellung eines Substrats (3) mit einer gemusterten optischen Beschichtung auf einer gewölbten Oberfläche vor, bei welchem
auf der gewölbten Oberfläche eine Maskierung (5) aufgebracht wird, welche einen Teilbereich der gewölbten Oberfläche bedeckt, eine optische Beschichtung mit einem Vakuumabscheideverfahren aufgebracht und die Maskierung entfernt wird.
Ein insbesondere mit dem Verfahren herstellbares beschichtetes Substrat weist eine gewölbte Fläche auf, die mit zumindest einer gemusterten optischen Beschichtung derart versehen ist, daß die optische Beschichtung in zumindest einem Teilbereich dieser Fläche vorhanden ist und in zumindest einem benachbartem Teilbereich fehlt.
Abstract:
A method for creating a color filter on a display screen that allows better and more efficient adhesion of color pigment crystals to the screen display structure. In one embodiment, the present invention creates a color filter on a glass substrate having a pixel-defining structure. The present embodiment first creates a color filter slurry by mixing a polyvinyl alcohol solution with a color crystal pigment. The color filter slurry is then applied onto the interior surface of the display screen. The slurry is then dried. The dried color filter slurry is then exposed to an UV light from the exterior side of the display screen. The UV light exposes the color filter slurry through a photomask and through the display screen. The excess layer of color filter slurry is then removed, leaving behind a color filter of desired transmission wavelength such that light having similar wavelength are substantially transmitted and light of wavelengths different from said color pigment crystals are substantially filtered out by absorption.
Abstract:
A process for making a radiation filter element comprises the steps of: exposing part of an assemblage to infrared radiation, the assemblage comprising a donor comprising (1) a support capable of transmitting infrared light, and (2) a transferable layer comprising a transferable material and an infrared-absorbing dye, the transferable layer of the donor being in contact with a receiver to provide an exposed assemblage comprising an exposed part of the transferable layer and an unexposed part of the transferable layer; separating the receiver and the support of the exposed assemblage to obtain an imaged receiver and a spent donor, wherein the imaged receiver comprises the receiver, a transferred portion of the transferable material and a transferred portion of the infrared-absorbing dye, said transferred portion of the IR dye having a color and the spent donor comprises the support and a retained portion of the transferable layer; and heating the transferred portion of the transferable material and the transferred portion of the infrared-absorbing dye at a temperature ranging from about 100 degrees Celsius to about 350 degrees Celsius for a period of time sufficient to thermally decolorize 50% to 100% of the transferred portion of the infrared-absorbing dye, the heating being in the absence of a thermal bleaching agent to provide a radiation filter element suitable for use in a liquid crystal display. Preferably color filter elements of this invention are used in liquid crystal display devices.
Abstract:
A thin film patterning arrangement (6), comprising a substrate (1) and barriers (3) arranged to partition a surface of the substrate (1) into sub-areas(5) is disclosed. Said surface is of a polymeric material, and is coated with an at least partly inorganic coating (2). Thin film material (4) is preferably deposited on said thin film patterning arrangement (6).
Abstract:
A color-filter manufacturing method for manufacturing a color filter, with very little color unevenness, in a short period of time. According to the method, at least a single color of red, green and blue ink is discharged onto each pixel of a substrate by using an ink-jet head, and coloring is performed such that color density fluctuation among pixels colored in red is kept 5% or lower, color density fluctuation among pixels colored in green is kept 10% or lower, and color density fluctuation among pixels colored in blue is kept 3% or lower.
Abstract:
The present invention is directed to an ink, an ink sheet, a color toner and a color filter, each containing a specific bis-azo compound. The present invention further relates to the use of said bis-azo compound in an ink jet ink.
Abstract:
Visible and infra-red spectral filters based on arrays of uncoupled identical waveguides (2.1) having coherently modulated cross sections (2.2) offer many unique advantages, such as independence of the spectral position of the Bragg-resonance based transmission or reflection features on the angle of light incidence. The resulting spectral filters are mechanically and optically stable, do not degrade over time, and offer superior transmittance for use as band pass, narrow band pass, band blocking, short pass and long pass filters. Such filters are useful for a wide variety of applications including but not limited to biomedical analysis systems, spectroscopy, and optical communications systems.
