Publication number: 20020029588Abstract: An assembly of rib structures sandwiched between a dielectric glass layer and a glass substrate for use in a flat panel display, such as plasma addressed liquid crystal (PALC) displays, is formed by a number of methods. One method includes molding thermoplastic glass frit containing paste into rib structures, transferring the rib structures to a thin transparent layer of a thermoplastic dielectric glass frit containing composition on a drum, and transferring the rib structures with the thin transparent dielectric glass layer to a glass substrate having metallic electrodes already formed thereon.Type: ApplicationFiled: November 21, 2001Publication date: March 14, 2002Inventors: Jean-Pierre Themont, Jean-Jacques B.

Patent number: 6347536Abstract: The device includes a housing, a means for heating the housing, and a means for supporting, in the housing, at least one group composed of plates of malleable material under pressure at the temperature established in the housing. Moreover, the group includes generally flat molds and each mold includes at least one non malleable pitted surface under pressure at said temperature. The molds are inserted between the plates. Means are envisaged to apply a roughly uniform pressure, oriented perpendicularly to the surface of the plates to the entire group. This pressure is suitable for causing the production of convex surfaces of microlenses on the sides of the plates, which are opposite said pitted surfaces of the molds.Type: GrantFiled: November 22, 1999Date of Patent: February 19, 2002Assignee: Corning IncorporatedInventors: Pierre V.

Patent number: 6120946Abstract: A method of making an imaged ink pattern, wherein an ink receiving surface is formed which has a raised surface pattern thereon and ink is transferred to the raised surface pattern by bringing the raised surface pattern into contacting relationship with an intaglio ink imaging pattern. The raised surface pattern is extended into the intaglio ink imaging pattern so that only the raised surface pattern of the ink receiving surface contacts the ink in the intaglio ink imaging plate.Type: GrantFiled: July 30, 1998Date of Patent: September 19, 2000Assignee: Corning IncorporatedInventors: Ronald E. Johnson, Jean-Pierre Themont

Patent number: 6001515Abstract: A method and apparatus for making color filters for liquid crystal display panels. A transfer layer is formed on a collector roll, and a raised pattern corresponding to the desired black matrix pattern is formed on the transfer layer by an embossing means. A plurality of colored ink patterns is formed in the appropriate location within the boundaries formed by the raised pattern, thereby forming the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate. Preferably, the multicolored ink pattern is deposited to a substrate while in a deformable state, flattened during the deposition process, and the deformed, more uniform shape of the printed cells is thereafter retained, preferably by curing during deposition to the substrate.Type: GrantFiled: June 10, 1997Date of Patent: December 14, 1999Assignee: Corning IncorporatedInventors: James L. Evans, Ronald E. Johnson, Candace J. Quinn, Jean-Pierre Themont

Patent number: 5701815Abstract: The invention relates to methods and apparatus useful for making color filters for liquid crystal display panels. A multicolored ink pattern is deposited to a substrate while in a deformable state, flattened during the deposition process, and the deformed, more uniform shape of the printed dot is thereafter retained, preferably by curing during deposition. The transfer layer is preferably formed on a collector roll. A plurality of colored ink patterns is then transferred to the collector roll, preferably from a single pattern roll having multiple patterns thereon, to form the multicolor image that will become the color filter. This multicolored image is then transferred to the substrate.Type: GrantFiled: January 25, 1996Date of Patent: December 30, 1997Assignee: Corning IncorporatedInventors: Peter L. Bocko, Bernard A. Eid, Ronald E. Johnson, William E. Lock, Robert D. Shoup, Jean-Pierre Themont

Patent number: 5623368Abstract: A plate of a deformable optical material is pressed against a rigid surface furrowed with a congruent network of alveoli by subjecting the two faces of the plate to fluid pressures of different values, the pressure on the face opposite the alveolate surface being less than the pressure on the other face of that plate. The alveoli are deeper than the thickness of the convex part of the microlenses formed therein by permanent deformation of the plate under the applied pressure.Type: GrantFiled: June 29, 1995Date of Patent: April 22, 1997Assignee: Corning IncorporatedInventors: Pierre V. Calderini, Thierry L. A. Dannoux, Gilbert D. Pujol, Jean-Pierre Themont

Patent number: 5353148Abstract: This invention relates to an electrochromic device comprising a layer (2') of an electrochromic product held between two conducting layers (5',6') each formed on one face of a transparent plate (3',4'), electrodes formed on each of the conducting layers, and a source of direct current for selectively supplying these electrodes with electrical energy. Electrodes (8', 9', 10, 11) are of elongated shape and extend over facing surfaces of the two conducting layers (5',6'), essentially symmetrical with respect to the plane of the electrochromic layer (2').The invention has application to windows in the building industry or the automobile industry (windshields, windows, rear view mirrors, etc.Type: GrantFiled: August 21, 1992Date of Patent: October 4, 1994Assignee: Corning IncorporatedInventors: Bernard A.
