  • Patent number: 9129922
    Abstract: An organic light-emitting display device and a method of manufacturing the same. The organic light-emitting display device has a structure including an organic layer between a pixel electrode and an opposite electrode, the organic layer including a emissive layer and an insulating layer defining a light emission area. Accordingly, the insulating layer included in the organic layer functions as a pixel-defining layer, and thus, “edge open”, which is generated when forming an emissive layer on a thick pixel-defining layer according to the comparable art, may be reduced or prevented.

  • Patent number: 8613989
    Abstract: A laser induced thermal imaging (LITI) apparatus and a method of making an electronic device using the same are disclosed. The LITI apparatus includes a chamber, a substrate support, a contact frame, and a laser source or oscillator. The LITI apparatus transfers a transferable layer from a film donor device onto a surface of an intermediate electronic device. The LITI apparatus uses a magnetic force to provide a close contact between the transferable layer and the surface of the intermediate device. The magnetic force is generated by magnetic materials formed in two components of the LITI apparatus that are spaced apart interposing transferable layer and the surface of the intermediate device. Magnets or magnetic materials are formed in the two following components of the LITI apparatus: 1) the intermediate device and the film donor device; 2) the intermediate device and the contact frame; 3) the substrate support and the film donor device; or 4) the substrate support and the contact frame.
