Abstract: A donor film that is easily handled in a process without adding a separate member (such as a tray) when an organic thin film is formed on a substrate by using a thermal transfer method is disclosed. In addition, a method of manufacturing the donor film and a method of manufacturing an organic light-emitting device using the donor film are disclosed. The donor film includes: a base film; a light-to-heat conversion (LTHC) layer on the base film; an interlayer on the LTHC layer and that includes a transfer region and a first protrusion corresponding to at least one edge of the LTHC layer; and a transfer layer on the interlayer and including an organic light-emitting material. A rigidity of the first protrusion is higher than a rigidity of the transfer region.

Abstract: A frame assembly to stretch a donor film used in laser induced thermal imaging (LITI), a method of manufacturing the donor film, and a method of manufacturing an organic light emitting device. The frame assembly to stretch a donor film includes: a main body including a center opening; a first support portion including a film mounting guide portion on which the donor film is mounted; a second support portion that including a film pressing portion that presses a donor film in a direction perpendicular to a coupling direction of the frame main body and the first support portion; and an elastic member disposed between the first support portion and the main body, wherein the first support portion is coupled to an inner portion of the main body by a first coupling member, and wherein the second support portion is coupled to an inner portion of the first support portion in a direction perpendicular to the coupling direction of the main body and the first support portion by a second coupling member.

Abstract: An apparatus for manufacturing an organic light-emitting display device, and a manufacturing method using the apparatus. An apparatus includes a roll drum unit configured to removably adhere a flexible substrate and a transfer film thereon such that the transfer film overlaps the flexible substrate, and a laser irradiation unit configured to irradiate a laser in a pattern toward the transfer film adhered on the roll drum unit and transfer a transfer layer of the transfer film onto the flexible substrate to form an emission layer.
