Abstract:
1. A method of fabricating an organic light emitting display panel, the method comprising: preparing a first roll around which a film is wound; substantially continuously drawing the film from the first roll so as to allow the film to pass through a plurality of chambers during which laser induced thermal imaging (LITI) is performed to transfer a transfer layer formed on the film to a substrate; maintaining a substantially vacuum state in each of the chambers while the film passes through the chambers through a gate unit installed at at least one of the chambers and disposed at at least one of a film inlet and a film outlet of each of the chambers that are installed; and substantially continuously winding the film which passes through the chambers around a second roll that is arranged corresponding to the first roll, wherein the chambers comprises a first chamber configured to receive the film released from the first roll, wherein the transfer layer is formed on a first surface of the film in the first chamber, wherein the chambers comprise a second chamber arranged close to the first chamber and configured to perform i) receiving the film output from the first chamber and ii) making the film and the substrate closely contact each other in the second chamber such that the transfer layer of the film faces the substrate, wherein the making of the film and the substrate closely contact each other comprises: contacting the substrate input into the second chamber and the film via a substrate input device; and supporting the film and substrate from upper and lower sides via a plurality of upper and lower combination rolls, respectively, and wherein at least one of the upper and lower combination rolls has an indented central portion.
