Abstract: A method of manufacturing an organic light emitting display apparatus is presented. The method includes providing a device substrate on which a first electrode and a pixel definition layer covering a portion of the first electrode are formed, forming a master substrate on which a transfer mask is patterned to mirror positions of the pixel definition layer, coupling the transfer mask to the pixel definition layer, forming an organic material layer on the exposed portion of the first electrode using the transfer mask as a protection layer, and removing the transfer mask. The transfer mask may replace a deposition metal mask.

Abstract: A tray assembly configured to stretch an object film includes a main frame on which the object film is placed and a fixing unit at sides of the main frame and configured to couple the object film to the main frame. The fixing unit includes an adhesive film coupled to the object film thereby coupling the object film to the main frame.

Abstract: In an evaporation source, a separable heater is used when an organic thin film is formed on a substrate in order to realize full-colors so that it is possible to correspond to crucibles of various capacities. The evaporation source comprises a crucible in which an organic material which is an organic thin film material is accommodated, and the crucible includes a heating unit and at least one spray nozzle for spraying the organic material onto a substrate. In the heating unit, a heater divided into at least two parts is provided on the external surface of the crucible at uniform intervals, and the heaters are separately disposed with respect to each other, but are connected to each other by connecting members. Therefore, it is not necessary to perform an additional design whenever the capacity of the crucible is changed, it is not necessary to exchange the evaporation source, and it is possible to reduce cost and to improve repairing ability.

Abstract: A vacuum evaporator including a vacuum chamber and a source arranged in the vacuum chamber to supply a deposition material to a substrate on which a layer is formed. A crystal sensor measures a deposition speed of the deposition material. The crystal sensor includes an insert having a hole, and the insert is arranged in front of the crystal sensor.
