  • Patent number: 9862639
    Abstract: A method of manufacturing curved touch window glass for a portable terminal, includes a plane glass processing process for processing plane glass to have a size capable of being changed to a predetermined size of completed curved glass, a printing process for printing a specific pattern on a back surface of the plane glass using ceramic ink, and a curved glass forming process for forming the curved glass in a high temperature atmosphere in such a manner that a curved surface is formed in at least one part of the plane glass having the printed pattern using an upper mold and a lower mold. The size of the plane glass on a plane which is processed in the plane glass processing process is shorter than a size measured along the curved surface of the completed curved glass, and the ceramic ink includes heat-resistant ink capable of withstanding a high temperature in the curved glass forming process.
