The technical field to which the invention relates.

The present invention relates to an organic EL display which uses an organic electroluminescent (hereinafter referred to as "organic EL") device.

Description of the prior art

As organic EL displays can be produced at relatively low cost and, in addition, the size of the EL display can easily be expanded, in recent years is promising to use these screens for products such as watches with digital display, phones, laptops, pagers, cell phones, calculators, etc. Generally speaking, the organic EL device forming organic EL display comprises a transparent electrode as an anode, an organic functional layer and a metal electrode as a cathode, which are sequentially deposited on the surface of the transparent substrate. Light can be emitted from the basics so that the pathogens, which are formed when electrons and holes, injected two electrodes placed so that the organic functional layer is between the anode and the cathode, recombine, return from the excited state to the ground state and generate light.

In this case, the organic functional layer is, for example, only swietoslawski the layer, a three-layer structure of the organic layer with transfer holes, a light-emitting layer and the organic elektroprenos layer or two-layer structure of the organic layer with transfer holes and the light-emitting layer, and, in addition, a multilayer body provided with a layer with the injection of electrons or holes and bearing layer located between the respective layers in these structures.

In this regard, the problem of organic EL devices is that when it is open to the atmosphere, it is very likely to deteriorate due to the influence of moisture, gases such as oxygen and the like, and other molecules of a certain type are present in the environment in which it is located. In particular, the lack of organic EL devices is that its performance is noticeably worse at the interface between the electrodes and an organic functional layer, and thus, degradation of light emission, such as brightness, color, etc.

In order to solve the above problems, an organic EL device, which has first and second display electrodes and at least one organic functional layer sandwiched between the respective electrodes of the display and consists of organic compounds, known to consistently cause on the surface the th framework such as glass and the like, a film of high-molecular compounds, which covers the organic EL device and the surface of the base along the perimeter of the organic EL device, and an inorganic barrier film that covers the film of high-molecular compounds and its edges, and also covers the surface of the base around the perimeter of the film of high-molecular compounds. In this case, the film quality high-molecular compound film is used aromatic polyurea formed from Monomeric materials by the method of polymerization by evaporation, and as the inorganic barrier film using the film of silicon nitride or film oxynitride silicon (Patent document 1).

Patent document 1: Japanese laid patent application publication No. 2004-281247 (see, e.g., paragraphs 0012, 0013 description).

Description of the invention

The problems facing invention

However, when using the film of high-molecular compounds, which is a film of aromatic polyurea, a problem arises in that the film-molecular compound is yellow in color, since the film of aromatic polyurea absorbs light in the wavelength range of 350-400 nm region of the visible light (350-830 nm), as shown in figure 2. Further, when the inorganic barrier film when aneesa film of silicon nitride or oxynitride silicon, since the film of silicon nitride or oxynitride silicon is brittle, when the application for any reason, the external force to the organic EL display outside there is a possibility that the inorganic barrier film will crack and sealing properties will deteriorate.

The essence of the invention

Given the above, the present invention is to provide an organic EL display, which will not be painted, even if it takes light in a specific wavelength range, and in addition, is shock resistant.

Tools to solve problems

To solve this problem, in the organic electroluminescent display according to the present invention, which contains: an organic electroluminescent device having first and second display electrodes and at least one organic functional layer, placed between the display electrodes and consisting of organic compounds; the basis for support organic electroluminescent device; a film of high-molecular compounds, which covers the organic electroluminescent device and the surface of the base along the perimeter of the organic electroluminescent device; and an inorganic barrier film that covers the film of high-molecular compounds, the edges of the film Vysokomolekulyarnye the connection and the surface of the base around the perimeter of the film of high-molecular compounds as a film-molecular compound film is used aliphatic polyurea.

According to the present invention, since the film quality of the high-molecular compound film is used aliphatic polyurea, even if the film of high-molecular compounds accepts light in the wavelength range, in particular, 350-400 nm, its coloration is suppressed, and it can maintain its colorless and transparent state.

In this case, when the film aliphatic polyurea formed from Monomeric materials by the method of polymerization by evaporation, it is possible preferably to obtain a high-purity film of high-molecular compounds, as solvent is not used.

Monomeric raw material preferably contains, for example, Monomeric aliphatic diamine and a Monomeric aliphatic diisocyanate.

Further, as the inorganic barrier film is used any substance, preferably selected from Al2O3, ZrO2, MgF2and ITO. Since a thin film formed of Al2O3, ZrO2, MgF2and ITO, has a low internal tension and bending (flexibility), even if for any reason, to the organic EL display externally applied external force, a thin film compensates for the external force and manifests high udarn the Yu strength. This reduces the likelihood that the inorganic barrier film will crack and sealing characteristics will deteriorate. Because these thin films is not fully absorb light in the wavelength range from 350 to 400 nm when they are printed on foil-molecular compound, which is the film aliphatic polyurea, they shall not be painted, even if you accept the light in the wavelength range, in particular, 350-400 nm, so that they can keep their colorless transparent state.

In this case, when the inorganic barrier film is formed by a method of electron beam evaporation, it preferably can be formed into a thin film in a state in which it has a low internal stress.

Further, when in turn caused several films of high molecular weight compounds and inorganic barrier film can preferably be obtained particularly high moisture-proof characteristics.

The effects of inventions

As described above, the EL display of the present invention has advantages in that it is not painted, even if it takes the light in a certain wavelength range and, in addition, that it has impact strength.

Description of the preferred embodiments

Preferred embodiments of the inventions

The agreement is but figures 1-2 position 1 means the organic EL display according to the present invention. Organic EL display includes a base 11, selected from inorganic substances such as glass and the like, and organic substances, such as high-molecular compound and the like, and the organic EL device 2 formed on the substrate surface 11. The organic EL device 2 is composed of the first electrode 21 of the display, which forms the anode, at least one organic functional layer 22, which consists of organic compounds, and the second electrode 23 of the display, which forms the cathode, and these display electrodes 21, 23 and the organic functional layer 22 deposited successively, and the organic functional layer 22 is located between the anode and cathode.

The first electrode 21 of the display is, for example, of ITO film and is formed by a known method such as a method of electron beam evaporation, sputtering method and the like, and is executed with a predetermined shape by the photolithography method. Organic functional layer 22 has a known structure and is constructed by successively applying a layer of injection holes, consisting of phthalocyanine copper layer with transfer holes, consisting of TPD (derived triphenylamine), light-emitting layer comprising Alq3(aluminum chelate complex) layer and injection of electrons formed of Li2O (lithium oxide), for example, by way of evaporation. Vtoro the electrode 23 of the display is formed, for example, the Al film formed by a known method such as a method of electron beam evaporation, sputtering method and the like, and is executed with a predetermined shape by the photolithography method.

Incidentally, when the organic EL device 2 open atmospheric conditions, it can deteriorate due to the influence of moisture, gases such as oxygen and the like, and a certain kind of other molecules present in the environment in which it is used. In particular, the characteristics of the organic EL device 2 is noticeably worse at the interface between the display electrodes 21 and 23 and the organic functional layer 22 of the organic EL device, resulting in worsening of the light-emitting characteristics, such as brightness, color, etc.

To cope with this problem, it is preferable to successively apply the film 3 high-molecular compounds, which covers the organic EL device 2 and the surface of the base 11 along the perimeter of the organic EL device 2 and the inorganic barrier film 4 that covers the film 3 high-molecular compounds, the edges of the film 3 high-molecular compound and the surface of the base 11 around the perimeter of the film 3 high-molecular compounds, in this organic EL device 2 must be guaranteed from painting, even if it takes light in a particular band, DL is n waves, and besides, to have impact strength.

In the implementation in the quality of the film 3 high-molecular compound film is used aliphatic polyurea. Film 3 aliphatic polyurea formed from Monomeric materials containing Monomeric aliphatic diamine and a Monomeric aliphatic diisocyanate, a method of polymerization by evaporation in a wider range than the display area including pixels, and an organic EL device using a mask in which is formed a given hole.

So, after the inner volume of the vacuum chamber is exhausted to a predetermined pressure corresponding to the monomers of aliphatic diamine and aliphatic diisocyanate is heated to the appropriate predetermined temperature, so that they were vaporized and passed into the gas phase. Then the corresponding monomers in contact on the base 11 and the organic EL device 2 react and precipitate, so that the organic molecules are polymerized. The result is a film 3 aliphatic polyurea given thickness to close the organic EL device 2 and the surface of the base 11 along its perimeter, as shown below. In this case, although the thickness of the film 3 aliphatic polyurea not particularly limited, it is preferable to set the thickness in the range from 300 nm to 1000 nm, so that olabilenleren inorganic barrier film 4.

[Formula 1]

[Formula 2]

As examples of Monomeric aliphatic diamine can be called 1,12-diaminododecane, 10-diaminododecane, 1,8-diaminooctane, 1,6-diaminohexane, 1,3-bis(aminomethyl)cyclohexane and the like, Hereinafter, as examples of Monomeric aliphatic diisocyanate can be called 1,3-bis(isocyanatomethyl)cyclohexane, hexamethylenediisocyanate etc.

Inorganic barrier film 4 formed on the film 3 aliphatic polyurea selected from Al2O3, ZrO2, MgF2and ITO and is formed by a method of electron beam evaporation. So, it is electron beam evaporation with a known structure, and after the internal volume of the vacuum chamber razreshaetsja to a specified pressure, a metal such as Al, Zr and the like, is heated by an electron beam and evaporates, and chemically active gas, such as oxygen, fluorine and the like, is introduced into the chamber, reacts and is deposited on the film 3 aliphatic polyurea, resulting in the formation of the desired thin film covering film 3 aliphatic polyurea film edge 3 aliphatic polyurea and the surface of the base 11 around the perimeter of the film 3 aliphatic polyurea. In this case, although the thickness of the inorganic barrier film 4 is not particularly limited, given the bending resistance and barrier properties, pre is respectfully set this thickness in the range from 50 nm to 200 nm. According to the above method, the evaporation rate can be set for each component, the composition of the thin film can be easily controlled and it is possible to prevent deterioration in characteristics of a thin film, as it is not damaged, in contrast to plasma, and in addition, it is possible to reduce the internal stress of the thin film.

In this case, it is possible to use a multilayer structure, causing in turn the film 3 high-molecular compounds and inorganic barrier film 4, so that it is possible to obtain a high resistance. Next, the film 3 aliphatic polyurea organic EL device 2 can be subjected to annealing in vacuum or in inert gas, such as N2and so, at a given temperature at which the organic functional layer 22 is not damaged by the discharge gases in the film, while inorganic barrier film 4 is not formed.

As described above, when the film 3 aliphatic polyurea and inorganic barrier film 4 is formed, because their coloration is suppressed, even if they accept the light in the wavelength range, in particular, 350-400 nm, they can keep their colorless transparent state. Further, since a thin film consisting of Al2O3, ZrO2, MgF2and ITO, has a low internal voltage and low resistance to bending,even if for any reason, to the organic EL display 1 externally applied external force, thin film absorbs the external force and exhibits high impact strength. This reduces the likelihood that the inorganic barrier film 4 will crack, and its sealing characteristics will deteriorate. Because these thin films is not fully absorb light in the wavelength range from 350 to 400 nm when they are printed on foil-molecular compound constituting a film 3 aliphatic polyurea, they shall not be painted, even if you accept the light in the wavelength range, in particular, 350-400 nm, so that they can keep their colorless transparent state.

Example 1

As the base used polyester film (PET) with a thickness of 50 μm, and a film-based method of polymerization by evaporation was formed first film aliphatic polyurea thickness of 1 μm using 1,12-diaminododecane and 1,3-bis(isocyanatomethyl)cyclohexane as monomer raw materials. On film aliphatic polyurea method of electron-beam evaporation was applied inorganic barrier film thickness of 0.1 μm consisting of Al2O3. Then on the first inorganic barrier film according to the same procedure, which is described above, were deposited second film aliphatic polyurea and a second inorganic barrier film having the same thickness as the above plank is, and in addition, the second inorganic barrier film was applied a third film aliphatic polyurea that has the same thickness as the above film (5-layer structure), thus was obtained A sample of example 1.

In addition, as the base was used polyester film (PET) with a thickness of 50 μm, as for the basics above, and on film-based method of polymerization by evaporation was formed film aliphatic polyurea thickness of 1 μm using 1,12-diaminododecane and 1,3-bis(isocyanatomethyl) cyclohexane as monomer raw materials. Next, on the film aliphatic polyurea method of electron-beam evaporation was caused by a layer of Al2O3a thickness of 0.1 μm (two-layer structure), thus was obtained a sample of the B variant of implementation 1.

Comparative example 1

As the base used polyester film (PET) with a thickness of 50 μm, and a film-based method of polymerization by evaporation was formed film of aromatic polyurea with a thickness of 1 μm using 4,4'-difenilmetana diisocyanate and 4,4'-diaminophenylmethane as monomer raw materials. Then the film is an aromatic polyurea way of reactive sputtering was deposited film of silicon nitride with a thickness of 0.1 μm (two-layer structure), thus was obtained the sample of comparative example 1.

The method then is m, the pressure increase was measured blagopoluchnye respective samples ("Vacuum" Volume 35, No.3, P 317 (1992)). Table 1 shows the transmission of moisture simultaneously with blagopoluchiem polyester (PET) film base. According to the results of the measurements can be seen that sample B has blagopoluchnye 0.1 g/(m2·day), and A sample made as a multilayer structure, can reach moisture resistance in excess of the limit measure blagopolutchna. Note that when blagopoluchnye samples option exercise 1 was measured again by re-winding them around a cylinder with a radius of 30 mm, 20 times, their permeability did not change, and therefore it can be concluded that the inorganic barrier film has a high resistance to bending and reduces the likelihood of deterioration of the sealing performance.

According to the results of measurement of the transmittance of the sample of comparative example 1 was reduced by approximately 10% after irradiation with ultraviolet light, and the sample turned yellow. On the contrary, it is possible to establish that the transmittance of the samples A and B did not change, even if they were irradiated with ultraviolet rays, and they remained colorless transparent state.

The invention discloses macromolecular compounds with a nucleus-shell structure, whereby the nucleus has a macromolecular dendritic and hyperbranched structure based on carbon or based on silicon and carbon is bonded to at least three, in particular at least six external atoms through a carbon-based coupling chain (V) which is selected from a group consisting of straight and branched alkylene chains with 2-20 carbon atoms, straight or branched polyoxyalkylene chains, straight or branched siloxane chains or straight or branched carbosilane chains, with straight chains based on carbon oligomeric chains (L) with conjugated double bonds on the entire length. Conjugated chains (L) in each separate case are bonded at the end opposite the coupling chain (V) to one more, specifically, aliphatic, arylaliphatic or oxyaliphatic chain (R) without conjugated double bonds. The chains (V), (L) and (R) form the shell. The invention also discloses a method for synthesis of the said compounds.

EFFECT: novel organic compounds which can be synthesised using conventional solvents and have good semiconductor properties.
