  • Substrate processing apparatus and display device using the same
    Patent number: 10825837
    Abstract: Various embodiments provide a substrate processing apparatus for grinding a substrate, and a display device including a substrate in which a hole is formed in an edge of the substrate using the substrate processing apparatus. The substrate processing apparatus for processing a display substrate includes a body which, in operation, rotates, a cylindrical grinding part connected to the body, and a lateral groove formed in a surface of the cylindrical grinding part. The lateral groove is configured to accommodate the display substrate. Thus, it is possible to form a hole by grinding an edge of the display substrate so as to be matched with a designed value.

  • Apparatus for processing a substrate and display device by using the same
    Patent number: 10748771
    Abstract: Disclosed herein is an apparatus for processing a substrate that forms a hole in a substrate while reducing a burr in the hole so that a module device can be inserted into the hole to reduce the thickness of a display device, and the display device using the apparatus. The apparatus for processing the substrate comprises a body configured to operably be rotatable, and a cylindrical cutting tip at an end of the body. The bottom surface of the cutting tip is in an acute angle with respect to a contact surface of the substrate to allow formation of a groove at the substrate.
