  • Publication number: 20220161369
    Abstract: A method of processing a glass laminate substrate includes carrying a glass laminate substrate including a glass substrate on a metal substrate to a processing location; radiating a laser onto the metal substrate through the glass substrate; and cooling a portion of the glass substrate, through which the laser is radiated, such that the glass substrate is cut at the portion through which the laser is radiated. When methods of processing and cutting a glass laminate substrate and an apparatus for processing a glass laminate substrate, according to embodiments, are used, a glass laminate substrate having high edge strength after cutting may be produced.

  • Publication number: 20100053761
    Abstract: A hybrid optical film, a display device having the same, and a method of manufacturing the same are provided. The hybrid optical film is provided in front of a display module of a display device to serve as a display filter. The hybrid optical film is in the form of a single-film. The hybrid optical film includes a film substrate; a first optical pattern directly formed on one side of the film substrate; and a second optical pattern directly formed on the other side of the film substrate. The hybrid optical film can reduce manufacturing costs due to a simplified structure and improve productivity due to a simplified manufacturing process.
