  "abstract": "A system for disassembling a display device includes a supporting part facing a window and supporting at least a portion of the window. A window fixing part is disposed on the supporting part and is configured to fix a position of the window with respect to the supporting part. A display panel stopper is positioned above the supporting part and is spaced apart from the supporting part by a predetermined distance. A window pressurizing part is configured to apply pressure to the second region of the window along a first orthogonal to an upper surface of the supporting part. A separating stick is movable along a second direction which intersects the first direction. The separating stick is configured to be inserted between the window and a display panel adhered to the window.",
  "claims": [

A system for disassembling a display device, the system comprising: a supporting part facing a window and supporting at least a portion of the window, wherein the window comprises a first region and a second region; a window fixing part comprising a first fixing plate and a second fixing plate disposed on the supporting part and configured to fix a position of the window with respect to the supporting part; a display panel stopper positioned above the supporting part and spaced apart from the supporting part by a predetermined distance; a window pressurizing part comprising a pressurizing plate including at least one pressurizing protrusion extending from the pressurizing plate, wherein the at least one pressurizing protrusion is configured to apply pressure to the second region of the window along a first direction orthogonal to an upper surface of the supporting part; and a separating stick movable along a second direction, wherein the second direction intersects the first direction, and wherein the separating stick is configured to be inserted between the window and a display panel adhered to the window.",
    "2. The system of claim 1, wherein the supporting part includes at least one receiving groove configured to receive the window when pressure is applied to the window by the window pressurizing part.",
    "3. The system of claim 2, wherein the at least one receiving groove is configured such that the second region of the window is downwardly moved along the first direction by the window pressurizing part by from about 3 mm to about 8 mm.",
    "4. The system of claim 1, wherein the window fixing part includes contact bars in direct contact with opposite end portions of the first region of the window facing along a third direction intersecting the first direction and the second direction.",
    "5. The system of claim 4, wherein the opposite end portions of the window are upwardly bent along the first direction.",
    "6. The system of claim 4, wherein the contact bars are movable along the first direction and the third direction.",
    "7. The system of claim 1, wherein the display panel stopper is disposed on the display panel along the first direction.",
    "8. The system of claim 7, wherein the display panel stopper is positioned to be substantially in parallel with the display panel.",
    "9. The system of claim 1, wherein the display panel stopper includes: a first plate positioned to be substantially in parallel with the display panel; and at least one impact absorbing part coupled to the first plate, and including a contact plate facing the display panel and an elastic member coupled to the contact plate.",
    "10. The system of claim 9, wherein the contact plate adsorbs and fixes the display panel.",
    "11. The system of claim 1, wherein the at least one pressurizing protrusion is in direct contact with the second region and is configured to provide downward pressure to the second region of the window along the first direction.",
    "12. The system of claim 11, wherein a first pressurizing protrusion and a second pressurizing protrusion extend from the pressurizing plate, and wherein the first and second pressurizing protrusions are arranged along a third direction intersecting the first direction and the second direction.",
    "13. The system of claim 11, wherein the at least one pressurizing protrusion includes a bar-shaped member extended along the first direction; and a pressurizing tip coupled to the bar-shaped member and including a flexible material.",
    "14. The system of claim 13, wherein: the at least one pressurizing protrusion is configured to apply a force of from about 8 kgf to 12 kgf to the second region of the window.",
    "15. The system of claim 1, wherein the separating stick includes a first inclined surface at one end portion thereof.",
    "16. The system of claim 15, wherein the first inclined surface of the separating stick is directed toward the display panel.",
    "17. The system of claim 1, further comprising: a cooling part comprising a heat conductor in direct contact with the supporting part, wherein the heat conductor is configured to cool the supporting part.",
    "18. The system of claim 17, wherein: the cooling part cools the supporting part to from about −70° C. to about −100° C.",
    "19. The system of claim 17, wherein: the supporting part includes at least one metal including cooper (Cu) or aluminum (Al).",
    "20. A method for disassembling a display device, the method comprising: providing a display device including a window, wherein the window includes a first region and a second region positioned around the first region, and wherein a display panel is disposed on the first region of the window; cooling the display device; fixing, by a window fixing part, a position of the window to a supporting part supporting at least a portion of the window; applying pressure, by a window pressurizing part, to the second region of the window along a first direction orthogonal to an upper surface of the window and intersecting the second region of the window; and inserting a separating stick between the window and the display panel along a second direction intersecting the first direction at the second region of the window.",
    "21. The method of claim 20, wherein the cooling of the display device is performed before the display device is disposed on the supporting part.",
    "22. The method of claim 20, wherein the cooling of the display device is performed after the display device is disposed on the supporting part.",
    "23. The method of claim 20, wherein the window fixing part includes contact bars in direct contact with opposite end portions of the first region of the window facing along a third direction intersecting the first direction and the second direction.",
    "24. The method of claim 23, wherein the opposite end portions of the window are upwardly bent along the first direction.",
    "25. The method of claim 20, wherein the window pressurizing part includes at least one first pressurizing member in direct contact with the second region and configured to downwardly press the second region along the first direction."

  "description_excerpt": "An exemplary embodiment of the present invention provides a system for disassembling a display device and a method for disassembling a display device using the same in which damage occurring during separating a display panel and a window is reduced or eliminated. An exemplary embodiment of the present invention provides a system for disassembling a display device including a supporting part facing a window and supporting at least a portion of the window. A window fixing part is disposed on the supporting part and is configured to fix a position of the window with respect to the supporting part. A display panel stopper is positioned above the supporting part and is spaced apart from the supporting part by a predetermined distance. A window pressurizing part is configured to apply pressure to the second region of the window along a first orthogonal to an upper surface of the supporting part. A separating stick is movable along a second direction which intersects the first direction. The separating stick is configured to be inserted between the window and a display panel adhered to the window.\n\nThe supporting part may include at least one receiving groove having a shape corresponding to a shape of the window. The at least one receiving groove may be configured to receive the window when pressure is applied to the window by the window pressuring part. The window fixing part may include contact bars in direct contact with opposite end portions of the first region of the window facing along a third direction intersecting the first direction and the second direction.",
