  • Encapsulation for organic devices
    Patent number: 7193364
    Abstract: A method of encapsulating devices including providing a getter layer in the penetration path of atmospheric elements. The getter layer serves as a barrier to potentially deleterious atmospheric components, such as moisture and gases, that penetrate the device. In one embodiment, the getter layer surrounds an active region where active component or components are formed.

  • Uniform deposition of organic layer
    Patent number: 7148624
    Abstract: A method to ensure uniform deposition of organic layer is disclosed. Since the organic layer is very thin, any deviation from the target thickness will result in visible optical defects. A homogenous layer which exhibits good coating behaviour with organic materials is provided beneath the organic layer. By covering the metal interconnects, the adverse effect on the uniformity of the polymer layer is reduced or prevented.

  • Electrode patterning in OLED devices
    Patent number: 7049630
    Abstract: An OLED device having pillars with a cross section that is wider on the top. The pillars structure a conductive layer during deposition into distinct portions located between the pillars and on the top of the pillars. In one embodiment, the grooves between the pillars extend outside the electrode region to prevent shorting of adjacent electrodes.

  • Interconnection for organic devices
    Patent number: 7026660
    Abstract: A device having bond pads within a bond pad region, the bond pads comprising a conductive material that is stable when exposed to atmospheric constituents. The bond pads can be formed from conductive oxide materials such as indium tin oxide. A contact layer is provided to enhance the conductivity between the bond pads and the active component of the device.

  • Method of fabricating electronic devices
    Patent number: 6887733
    Abstract: A method of encapsulating an organic device including flash evaporating a getter layer on the substrate is disclosed. The getter layer comprises an alkaline earth metal, such as barium. The getter layer serves to protect the active components by absorbing surrounding moisture and gases.
