Abstract: Systems and methods are provided for manufacturing a window from a transparent member. Forming the window may include forming of a groove by irradiating first laser light and removing a portion of a transparent member by irradiating second laser light focused at a depth of the groove. The first laser light may be emitted from a first laser generator and may be irradiated along an edge of a first area defined in a second surface of the transparent member. A second laser light may be focused to the depth of the groove, and thus a portion of the transparent member may be cut. The second laser light may be emitted by a second laser generator, and a focus of the second laser light may be located within the transparent member.

Abstract: Provided is a method of thermoforming a molding material to have a bent portion and a flat portion extending from the bent portion. The method includes: placing the molding material on a bending mold, the bending mold having a curved surface; and forming the bent portion of the molding material by heating a portion of the molding material at least to a fluidization temperature such that the portion of the molding material bends due to the weight of the flat portion of the molding material to form the bent portion according to a shape of the bending mold.
