  • Patent number: 11667106
    Abstract: A method of manufacturing a display device includes: preparing a cover window including a bent part on a side surface thereof, and a guide film including a surface on which a display panel and an adhesive layer are arranged; arranging the cover window and the guide film in a face-to-face manner such that the adhesive layer faces the cover window; seating the guide film onto a seating pad of a first jig; pre-forming the display panel by bringing opposite ends of the guide film into close contact with opposite side surfaces of the seating pad using a pair of push members; and joining the display panel with the cover window by bringing the adhesive layer into contact with the cover window.

  • Patent number: 10348209
    Abstract: Provided is a DC/DC converter which has a full bridge configured in a switching unit and uses a half bridge, which is subordinate to the full bridge in view of circuit configuration, to automatically select such one of the multi-topologies. More particularly, the DC/DC converter uses multi-topologies, which receives, in real time, feedback of an output voltage charged to a battery, operates using the half bridge when the output voltage charged to the battery is lower than a reference voltage, and operates using the full bridge when the output voltage charged to the battery is equal to or higher than the reference voltage, so as to output a wider range of voltage.

  • Patent number: 9731492
    Abstract: A substrate peeling apparatus includes a support member and absorption pads. The support member, having a quadrangular shape, includes first and second vertexes diagonally facing each other in a first direction, and third and fourth vertexes diagonally facing each other in a second direction crossing the first direction. The absorption pads is disposed on the support member. The absorption pads are arranged in rows in a direction parallel to the first direction and at least one absorption pad of each row is arranged in a direction parallel to the second direction. An absorption pad of each row includes a hole having an increasing internal diameter as a distance in the first direction between the each row and the first vertex increases. An internal diameter of an absorption pad in a row positioned halfway between the first and second vertexes has a maximum internal diameter.

  • Publication number: 20120148739
    Abstract: A method for manufacturing metal nanostructure which can manufacture a metal nanostructure which has the structure and properties different from the structure and properties of a conventional material and can be properly used in various applications is provided. The method for manufacturing metal nanostructure includes the steps of: preparing metal-coated organic nanofibers in which surfaces of the organic nanofibers are coated with metal; and preparing a metal nanostructure having the structure where the organic nanofibers are used as a template by removing organic components from the metal-coated organic nanofibers by heating the metal-coated organic nanofibers at a temperature ranging from 250° C. to 600° C.
