摘要： A barrier for preventing water or oxygen from a source thereof from reaching a device that is sensitive to water or oxygen. The barrier is constructed by depositing a first polymer layer between the device and the source. An inorganic layer is deposited on the first polymer layer of the device by plasma enhanced chemical vapor deposition utilizing an electron cyclotron resonance source ECR-PECVD. A second polymer layer is then deposited on the inorganic layer. The inorganic layer is preferably an oxide or nitride. A second barrier layer having a compound that absorbs oxygen or water can be placed between the inorganic layer and the device to further retard the passage of oxygen or water. The present invention is particularly useful in encapsulating electroluminescent displays.

摘要： An organic light emitting device having a process compatible current self-limiting (CSL) structure applied in the vicinity of an electrode of the device prevents the occurrence of high current flow in the vicinity of a short within the device. Should a short occur, the CSL structure becomes resistive, or non-conducting in the vicinity of the short, thus preventing the occurrence of “runaway” current in the vicinity of the short. By limiting the current flow between conductors in the device, the non-emissive areas of the device can be minimized, thus improving the overall reliability of the device.

摘要： An organic polymer based display and method for making the same. The display is constructed on a flexible sheet having first and second surfaces, the first and second surfaces being parallel to one another. The flexible sheet is transparent to light of a first wavelength. A first electrode, which includes a first electrode layer in contact with the first surface, is deposited on the flexible sheet. The first electrode layer is also transparent to light of the first wavelength. A light-emitting layer that includes an organic polymer is deposited on the electrode layer. A second electrode that includes a second electrode layer in contact with the light emitting layer is deposited on the light-emitting layer. The light emitting layer generates light of the first wavelength when a potential difference is applied across the first and second electrodes. A light conversion layer is deposited in contact with the second surface of the flexible sheet. The light conversion layer absorbs light of the first wavelength and emitting light of a second wavelength. In an addressable pixelated display, the light conversion layer and one of the first or second electrodes are patterned as parallel strips overlying one another.

摘要： A PPV based electroluminescent device and method for constructing the same. The electroluminescent device is constructed on a substrate by depositing a layer of material having a PPV precursor and photoacid generator on the substrate. The substrate typically includes the anode for the device. The PPV precursor is converted to PPV in the presence of an acid. The photoacid generator produces an acid when exposed to electromagnetic radiation. Those portions of the layer that are not to contain electroluminescent elements are masked. The unmasked portion is then illuminated with electromagnetic radiation; and any unreacted PPV precursor is removed to provide a plurality of isolated PPV regions on the substrate. An electron transport layer is then deposited over the PPV regions and the cathode is deposited on top of the electron transport layer. By properly choosing the thickness of the electron transport layer, the electron transport layer also provides electrical isolation between the anode and cathode in the regions of the device that do not include PPV elements.

The base layer is impermeable to oxygen and water. The substrate includes a plurality of wells defined by a barrier layer, each well having an electrode layer connected electrically with the conducting surface. A removable protective layer covering the wells protects the electrode layer from attack by oxygen and water prior to being utilized to make the display. In one embodiment, each of the wells also contains an electron transfer layer in contact with the electrode layer. The electron transfer layer includes a material that improves the efficiency of the injection of electrons from the electrode layer into the electroluminescent layer of the display. This display is fabricated by moving a first dispenser relative to the substrate so as to quantitatively deposit a first electroluminescent material on the substrate, different amounts of the first electroluminescent material being deposited at different locations on the substrate in response to signals defining an illumination pattern to be generated by the display. A conducting material is deposited on the first electroluminescent material. In color displays, a second electroluminescent material is also deposited, the second electroluminescent material emitting light at a different wavelength than the first electroluminescent material. A non-luminescent material, which is preferably an electrical insulator, can be deposited in wells at locations on the display that are not to emit light prior to depositing the conductive material.

摘要： A display having a plurality of addressable pixels and a method for constructing the same. The display includes a substrate having a first conducting layer thereon. The conducting layer includes a plurality of parallel row electrodes having edges separated by insulating material. A first polymer layer constructed from one or more thin films overlies the parallel row electrodes. An insulating layer overlies the polymer layer, the insulating layer having windows therein defining pixels for the display. The insulating layer overlies the edges of the row electrodes while providing access to the first polymer layer in the area of the pixels. A second conducting layer overlies the insulating layer and includes a plurality of separated column electrodes. Each column electrode crosses a plurality of the row electrodes and is located over the windows in the insulating layer at points defining the pixels. The second conducting layer is preferably constructed by depositing a layer of photoresist over the insulating layer and patterning the layer of photoresist to provide openings extending therethrough. The openings are wider in the portion of the layer nearest to the insulating layer. This layer acts as a shadow mask for depositing a layer of conducting material. In one embodiment of the invention, a second polymer layer is located between the insulating layer and the second conducting layer. The insulating layer is preferably constructed from a layer of photoresist that is baked to cross-link the photoresist. The polymer layers include an electroluminescent material, which is preferably based on a polyfluorene.
