METHOD FOR MANUFACTURING A COLOR SLIDE FOR AN AUTOMOBILE PROJECTION LAMP
A method for manufacturing a color slide for an automobile projection lamp includes: forming a plurality of same color pattern units on a glass substrate, each of the color pattern units being composed of a plurality of color coating layers. The plurality of color coating layers are formed by sequentially depositing materials having different colors on a surface of the glass substrate in accordance with different colors. Finally, the glass substrate is cut and separated in unit of one color pattern unit to form an independent color slide with the color pattern. The color slide can be mounted to an automobile projection lamp system for projecting the color pattern.

METHODS OF MAKING COATED GLASS-BASED PARTS
Making a glass-based article having a coating and a target shape which comprises a planar central portion and a perimeter portion which borders at least part of the planar central portion and extends out of the plane of the planar central portion, the perimeter portion having a perimeter edge and a target edge-to-opposite edge dimension. The method includes forming a glass-based part to provide an initial formed part having an initial three-dimensional shape that is different from the target shape for at least the target edge-to-opposite edge dimension. Applying a coating to the initial formed part to form the glass-based article having a coating, the coating imparting a stress to the initial molded part that causes a calculated, warp-induced change to the initial shape.

Oleophobic Coatings for Glass Structures in Electronic Devices
An electronic device includes electrical components in a housing. The components may include optical components such as a display. Protective structures may be used to protect the optical components. The protective structures may include one or more protective transparent layers such as layers of glass or crystalline material such as sapphire. The protective transparent layers may be coated with an oleophobic coating. To enhance coating durability, catalyst may be used to help bond the oleophobic coating. An adhesion promotion layer such as a silicon oxide layer may be deposited on the transparent protective layer. A catalyst layer such as a layer of sodium fluoride may be deposited on the adhesion promotion layer. The oleophobic material may be evaporated or otherwise deposited on the catalyst layer. Heat and moisture may help the oleophobic material form chemical bonds with the adhesion promotion layer, thereby forming a durable oleophobic coating.
Broadband and Omnidirectional Polymer Antireflection Coatings
A method for generating antireflective coatings for polymeric substrates using a deposition process and/or a dissolving process can provide a coating onto the outer surface of the substrate. Some embodiments can include a GLAD generated fluoropolymer coating or a co-evaporated fluoropolymer coating on a substrate that may achieve ultralow refractive index as well as improved adhesion and durability properties on polymeric substrates. In some embodiments, the deposition process is performed such that a fluoropolymer can be evaporated to form chain fragments of the fluoropolymer. The chain fragments diffused into the substrate can subsequently re-polymerize, interlocking with the polymer chains of the substrate. In some embodiments, the co-evaporation process can form a nanoporous polymer chain scaffold of the fluoropolymer, from which a sacrificial material can be dissolved out. The formed coating can be a multilayer or continuously-graded antireflective coating that has strong adhesion with the substrate.
Interchangable center section for glass coating hood
An apparatus for coating glass articles includes a housing structure defining a chamber for receiving air or other fluid from a source of pressurized air that is in fluid communication with the chamber. The housing structure has an open end and a surface defined along at least a portion of the open end. A hot-swappable insert is removably positioned on the surface. The hot-swappable insert has a series of apertures for distributing the air or other fluid from the chamber and onto a surface of the glass articles that are positioned adjacent the insert. The insert can be replaced with another insert to adjust the flow path of the air or other fluid onto the glass articles.
