TECHNOLOGY OVERVIEW
OLED technology has already penetrated the handheld market, and its advantages -‐ stunning contrast, high power efficiency, wider viewing angles, better response time and easy "printing" onto flexible materials -‐ mean it will inevitably seep upwards into larger or more innovative devices. 1
A typical OLED is composed of an emissive layer, a conductive layer, a substrate, and both anode and cathode terminals. The layers are made of organic molecules that conduct electricity. A voltage is applied across the OLED such that the anode is positive with respect to the cathode. This causes a current of electrons to flow through the device from cathode to anode. Thus, the cathode gives electrons to the emissive layer and the anode withdraws electrons from the conductive layer.

The emissive layer then becomes negatively charged, while the conductive layer becomes rich in positively charged holes. Electrostatic forces bring the electrons and the holes towards each other and they recombine. This recombination causes a drop in the energy levels of electrons, accompanied by an emission of radiation whose frequency is in the visible region. A clear, crisp bright image then follows.
OLEDs can be categorized into two main display types: Passive-‐Matrix and Active-‐Matrix. Passive-‐matrix OLED (PMOLED) displays have cathode strips, organic layers and anode strips. The anode strips are arranged perpendicular to the cathode strips. The intersections of the cathode and anode make up the pixels where light is emitted. External circuitry applies current to selected anode and cathode strips, determining which pixels get turned on and which pixels remain off. The brightness of each pixel is proportional to the amount of applied current.
In Active-‐matrix OLED (AMOLED) displays, full layers of cathode, organic molecules and anode are present, but the anode layer overlays a thin film transistor (TFT) array that forms a matrix. The TFT array itself is the circuitry that determines which pixels get turned on to form an image.

PORTFOLIO OVERVIEW
This Patent Sale Offering contains over 50 (including 24 US patents) worldwide assets grouped into three categories: OLED Manufacture, OLED Patterning, Flexible OLEDs and Other Devices. A brief summary of the technology areas covered by the patents in this Portfolio follows below.
• Manufacture: The OLED manufacturing process is continuously evolving with an eye toward producing thinner and lighter displays, improving display brightness and illumination, and new sealing techniques to decrease permeability of water and oxygen.
• Patterning: In the construction of a pixilated OLED, the transparent electrode is usually patterned in strips running in a single direction. After placement of the organic layers, the final electrode is patterned in strips in the orthogonal direction. More advanced techniques of patterning are necessary to prevent the exposition of water and hydrogen to the cathode in order to prevent degradation. The market is also focused on methods to improve the quality of multi-‐color displays, expand the choice of films used to create the pattern, and reduce the cost of fabrication.
• Flexible and Other Devices: OLEDs may be fabricated on flexible plastic substrates as opposed to glass substrates leading to OLED roll-‐up display fabrications to be used in electronics and other devices. The substrate used can be flexible, such as polyethylene terephthalate (PET), and thus the displays can be produced inexpensively. Another advantage is the flexible display does not break as easily, an important attribute for mobile and automobile applications.

with a second transparent substrate that provides a moisture-proof seal. Since the active layers are protected from permeability of water and oxygen without the need for a seal on the edge of the emission region, a greater intensity in the radiation region is available. Thus, the brightness of the source can be reduced without losing surface illumination, and in turn the life of the lighting source is lengthened.
US Patents 6,137,221
Title: Organic Electroluminescent Device with Full Color Characteristics
U.S. Patent 6,137,221, “Organic Electroluminescent Device with Full Color Characteristics,” was filed on July 8, 1998 and focuses on improving organic light emitting diodes for use in matrix-‐addressed displays.
The ‘221 patent discloses a method for printing color conversion layers on thin, flexible polyethylene terephtalate (PET) substrates on opposite sides to an indium tin oxide (ITO) anode film. The result is lower production costs and improved wide angle color purity in flexible thin displays.
US Patent 6,146,225
Title: Transparent, Flexible Permeability Barrier for Organic Electroluminescent Devices
U.S. Patent 6,146,225, “Transparent, Flexible Permeability Barrier for Organic Electroluminescent Devices,” was filed on July 30, 1998 and is directed to an enhanced method for sealing an organic light emitting display in order to improve the lifetime of the display.

Display devices need to be properly sealed to avoid water and oxygen from reaching the cathode and polymer layers. However, polymers with low permeability to water and oxygen are not available. Therefore, a sealant coating needs to be applied to the polymer and cathode layers in order to prevent destruction by water and oxygen. One method to achieve the desired permeability is the Polymer Multilayer (PML) technique. In this method, a layer of polymer and a layer of aluminum oxide are applied to the flexible PET substrate for sealing. This improves resistance in permeation to water and oxygen by three to four times. However, the films are not resistant enough to permeability and thus lifetime of the OLED is still insufficient.
The ‘225 patent discloses a method to prevent device water and oxygen permeation. The method includes placing a barrier between the device and source, placing an inorganic layer of the first polymer layer by plasma enhanced chemical vapor deposition using an electron cyclotron resonance source (ECR-‐PECVD), and a second polymer layer on the inorganic layer. Furthermore, a second barrier layer can be placed between the inorganic layer and the device to further prevent the passage of oxygen and water. The method is sought to be 40 more times effective than PET.
US Patent 6,366,017
Title: Organic Light Emitting Diodes with Distributed Bragg Reflector
U.S. Patent 6,366,017, “Organic Light Emitting Diodes with Distributed Bragg Reflector,” was filed on July 14, 1999 and discloses a method for fabrication of novel structures for organic light emitting diodes.

A typical organic light emitting device (OLED) is produced on a transparent substrate and radiated through the substrate to create light and consists of a glass substrate, a transparent anode layer, a hole transport layer, an electron transport layer, and a metallic cathode layer. In most cases, the electron transport layer is also the emission layer. As light passes through the transparent substrate, a substantial portion of light is wave-‐guided laterally and “lost” through the glass substrate. This decreases the perceived brightness of the OLED in the forward direction.
The ‘017 patent discloses an OLED that avoids the light guiding losses in the out-‐coupling of OLED emitted light within the glass substrates by using an opaque substrate such as silicon. The patent discloses a reflective electrode, an organic active layer providing electroluminescence, a transparent organic electrode and a distributed Bragg reflector (DBR). Initially, light from the active layer is directed backward and then reflected by the reflective layer increasing the brightness of the diode in the forward direction.
US Patent 6,710,542
Title: Organic Light Emitting Device with Improved Moisture Seal
U.S. Patent 6,710,542, “Organic Light Emitting Device with Improved Moisture Seal,” was filed on August 3, 2002 and discloses an improved method for sealing an organic light emitting display to enhance display lifespan.
The ‘542 patent discloses a device comprised of a substrate that is impermeable to water and oxygen and contains a first electrode in contact with an electroluminescent layer. A second electrode is also in contact with the electroluminescent layer and is protected from permeation of water and oxygen by a seal comprised of silicon nitride and a layer of epoxy.
