Manufacturing method for donor film with improved surface roughness
A manufacturing method using an additional heat-treatment process for a donor film with improved surface roughness. The improved donor film, used in a laser induced thermal imaging method, is capable of enhancing the lifetime of products and reducing the defect rates thereof. A manufacturing method for a donor film according to the invention, includes: providing a donor film comprising a base film, a light-to-heat conversion layer and an organic film; heating the donor film to provide a heat-treated donor film; and cooling the heat-treated donor film. The surface roughness of a donor film can be improved, and the non-uniform distribution of a laser on a region subjected to the LITI process can be minimized to prevent the over- or under-transfer of an transferred organic film, etc., and the non-uniform adhesion of the transferred organic film with an acceptor substrate.
