Disclosed is an organic electroluminescent display, comprising a first active electrode region and a first dummy electrode region, the first dummy electrode region electrically isolated from the first active electrode region. Further disclosed is an organic electroluminescent display, comprising a first active electrode region, a first dummy electrode region, and a blocking layer extending on said dummy electrode region preventing light emission.

Electroluminescent device with a blocking layer and a dummy electrode region

An electroluminescent device having a protection layer in the cap bonding region to which the cap is bonded. The protection layer can be formed from photosensitive or non-photosensitive materials. The protection layer protects the layers below from being damage during removal of polymer materials.

Encapsulation for electroluminescent devices

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.

Encapsulation for organic devices

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.

Uniform deposition of organic layer

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.

Electrode patterning in OLED devices

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.

Interconnection for organic devices

An OLED device having a conductive layer patterned by pillars to form electrodes in the device is disclosed, wherein portions of the pillars have at least 2 sub-rows to prevent shorting of adjacent electrodes. In one embodiment, the ends of the pillars are split into at least 2 sub-rows.
