  • Patent number: 11981597
    Abstract: A display module includes a display panel and a window. The window includes a base substrate and a plurality of functional layers. A central portion of the base substrate is flat, and an edge portion of the base substrate has a rounded shape. An upper portion of the edge portion of the window has the rounded shape and thus protrudes from a lower portion of the edge portion toward the outside. A first functional layer of the plurality of functional layers includes an acrylic-based material and/or an epoxy-based material, and a second functional layer of the plurality of functional layers includes a fluorine-based material.

  • Publication number: 20240076224
    Abstract: A molding method for a cover window includes: locally heating a peripheral portion of a glass substrate around a central portion of the glass substrate to a temperature of about 610° C. to about 670° C., forming a cover window by pressing the glass substrate, and annealing and cooling the cover window. Accordingly, a cover window in which each of edges has an outwardly convex curved surface through a glass substrate may be formed. In addition, the surface roughness of a cover window formed through a glass substrate may be improved.
