Description
Background of invention
Many organic electronic devices, for example organic luminescent device (OLED), integrated plastic circuit or organic radiation transducer (as organic phototransistor) are made up of some elements, they often are subjected to the influence of oxidant and moisture, thereby produce the deterioration of performance when this device is exposed in moisture or the oxygen.
The OLED device for example, comprises the function lamination that is positioned on the substrate.This function lamination comprises at least one or a plurality ofly is clipped in two organic function layers between the conductive layer.Conductive layer plays the effect (negative electrode and anode) of electrode.When voltage was applied to these electrodes, electric charge carrier injected these functional layers by these electrodes, and after these electric charge carriers are compound, just launched visible radiation (electroluminescence).Majority in the element of this function lamination, for example, organic function layer and cathode layer generally include alkali metal such as calcium or magnesium, and be very responsive to moisture or oxidant such as oxygen.Usually with the cover encapsulation, cover can comprise for example glass or pottery to this organic functions lamination on the substrate.
U.S. Patent Application Publication US2003/0038590A1 has described a kind of OLED device architecture, and wherein active OLED pixel is arranged on the substrate and with lid and encapsulates.The structuring getter layer that is made of IIA family metal or IIA family metal oxide such as calcium, barium, barium monoxide or calcium oxide is arranged in the packaging area, to absorb lastingly.Main shortcoming of this conventional device is often to cover as the cathode layer of top electrode layer getter material of no use.Therefore cathode layer may be still easily with the moisture or the oxygen reaction that infiltrate this device inside, and no matter there is this fact of getter layer (referring to Fig. 1).
In addition, in the current investigation that is at organic electronic device of the cover of thin-film package form.Organic electronic device often comprises the active region that comprises activeleg with band different-shape step.OLED for example can comprise the bar (bar) with extension, is used for conformation function layer and/or structure cathode layer, outstanding from the active region (referring to Fig. 2 to Fig. 4).These topographical steps produce the height irregular surface, are difficult to the deposit film encapsulation on it.
Summary of the invention
Therefore,, need have reliable encapsulation, be diffused into active organic zone to prevent moisture or oxidant for organic electronic device.In addition, for organic electronic device, have such needs, make by this way in its organic functions zone, makes the cover of thin-film package form easily to produce on the top in organic functions zone.
The present invention satisfies these needs by the organic electronic device as fundamental right requirement 1 is provided.Advantageous embodiments of the present invention is the theme of dependent claims.
According to the fundamental right requirement, theme of the present invention is a kind of organic electronic device, and it is responsive to moisture or oxidant, and comprises:
-substrate;
Organic functions zone on-this substrate comprises activeleg and has topographical steps,
Active polymeric barrier layer on-this organic functions zone,
-this active polymeric barrier layer can be in conjunction with moisture and oxidant, and the topographical steps in this organic functions zone of planarization and
The cover of this organic functions zone of-encapsulation and this active polymer.
Compare with the organic electronic device of the routine that comprises inorganic getter material, organic electronic device of the present invention provides an active polymeric barrier layer, its can be on one's own initiative in conjunction with and therefore in and penetrant such as moisture and oxidant.This combination can take place by for example chemistry or the Physical Absorption to penetrant.
Because the character of its polymer, active polymeric barrier layer manufactures much easier than conventional inorganic getter material, and can for example be deposited on the top electrodes of function lamination of this organic electronic device as liquid or paste, thereby make the topographical steps planarization that is present in usually in the organic functions zone.
This topographical steps is usually owing to the different elements of functional area.For the OLED device, these elements of this functional area can for example be the hollow layers that has the parting bead of the extension that is used to separate cathode strip or have the active pixel region that limits the OLED device.The OLED device that has the parting bead that has extension and have a hollow layer that limits active pixel has description in publication number is the unsettled German patent application of DE 10133686 A1, here it is introduced in full.
Topographical steps, for example parting bead can have the height of about 3 μ m.Therefore, can cover and the therefore topographical steps in planarization organic functions zone with active polymeric barrier layer, adjacent this compartment thickness that records with this topographical steps is bigger than the height of topographical steps.This planarization active polymeric barrier layer provides a plane for the generation of thin-film package then.
This active polymeric barrier layer preferably from polymeric matrix, the cyclenes copolymer of the cyclodextrine that has dispersion and have the polymeric matrix of acid anhydride and their mixture in produce.
Cyclodextrine is the cyclic oligomer of alpha-D-glucose, by for example effect generation of cyclodextrin glycosyltransferase (cyclodextrin glucotransferases) of certain enzyme.Cyclodextrine comprises six, seven or eight α-1, and 4-connects glucose monomer, known as α-, β-, cyclooctaamylose.This cyclodextrine molecule is orientated in special mode each other, makes to form continuous passage in the crystal lattice of this cyclodextrine.Therefore these passages have the big hollow inside of certain volume, and can be in conjunction with penetrant gas molecule for example.Penetrant even can combine with the cyclodextrine molecule with covalent manner, for example, by former hydroxyl glucose half six-carbon location and secondary hydroxyl (secondary hydroxyl group) at two of molecule-and three-carbon location.For dissolubility, compatibility and the thermostability that changes cyclodextrine, these hydroxyls also can replace by enough other groups.Also can be with the substituting group of hydroxyl with adjust to the right place a value between the bond strength of cyclodextrine and potential penetrant of bond strength.Therefore, cyclodextrine can neutralize enduringly, for example moisture or oxidant.Cyclodextrine preferably is dispersed in polymeric matrix such as the polypropylene.
Cyclenes copolymer can, for example, comprise two kinds of compositions that mix by extruding.A kind of composition is passable, for example, is oxidable polymer, as poly-(ethylene-methyl acrylate/cyclohexenyl group-methacrylate) (EMCM).Second kind of composition can for example comprise light trigger and catalyst, for example transition-metal catalyst.Two kinds of compositions can form so-called oxidation, purification system, and it can activate when for example being exposed to the UV radiation.The cyclene group of these polymer can pass through ring-opening reaction or aromatization and for example oxygen molecule generation chemical reaction then.
