  • Patent number: 9614192
    Abstract: A method for forming a thin film for fabricating an organic light-emitting diode (OLED) display is disclosed. In one aspect, the method includes forming a plurality of shadow masks on a substrate. The substrate is then bent to form a predetermined curvature in the substrate. A deposition source is placed at a position having an equal angle with respect to central and peripheral portions of the substrate. The method also includes depositing a deposition material from the deposition source on the substrate and the shadow masks to form a thin film.
