Abstract: A method of manufacturing a display apparatus includes separating a mother substrate that includes a plurality of connected unit display apparatuses into a plurality of separated unit display apparatuses. Each separated unit display apparatus includes a display panel and at least one supporting unit attached below the display panel. The display panel includes a display substrate that has a pad area on which are disposed a plurality of pads and a thin film encapsulation layer on the display substrate. The method further includes consecutively cutting the display panel and the at least one supporting unit of each separated unit display apparatus along cutting lines in the pad area, where a first cut surface of the pad area of the display substrate and a second cut surface of the at least one supporting unit are respectively cut at different angles.

Abstract: A laser cutting apparatus and a laser cutting method are provided. A laser cutting method includes: preparing an object on a stage; cutting the object into a set shape by relatively moving and irradiating a laser beam along the set shape with respect to the object; and performing uniform heating compensation to reduce accumulation of thermal energy of the laser beam resulting from a change of speed at a shift point where a travelling direction of the laser beam with respect to the object changes.

Abstract: An apparatus for laser machining is provided including a stage for supporting a substrate and a controller for generating an error compensation table, a motor driver for moving the stage, and an error compensation unit for generating a table to compensate for an error. The error compensation unit includes a grid plate disposed on the stage and an imaging unit for imaging the grid plate. The motor driver outputs a position synchronization signal to the imaging unit according to a position of the stage. The imaging unit receives the position synchronization signal from the motor driver and images the grid plate while moving the stage.
