[Prior Art] Electroluminescent organic screens are characterized by a very small thickness and are currently being developed for use in audio equipment (especially audio on automobiles) or mobile phones, and their use on televisions is currently Studying. These screens are widely known in the art as "OLED (from organic light-emitting diodes)" and will be used in the description herein. 0 LED is made of a first transparent, mainly planar support and is typically made of a glass or plastic polymer; the first row of transparent electrodes (usually made of ITO, a mixed tin and indium oxide) , which are deposited linearly and parallel to each other on the first support; two different electroluminescent organic substances of the double layer 'the first layer is the conductor of the electron and the second layer has no electrons, which is deposited in the first series On the electrode; a second series of electrodes (usually made of A1-Li or Al-Mg alloy or with a composite bilayer such as Al-LiF or Al-Li2〇) which are aligned and parallel and opposite each other The electrodes in the first row are orthogonal and contact the upper portion of the bilayer of the organic material such that it is contained between the two rows of electrodes; and a second support member that is not necessarily transparent, which may be glass Made of metal or plastic and substantially planar and parallel to the first support. The two supports are secured together along their perimeter by a bonding means such that the structure (electrode and electroluminescent organic 1267317 (2)) acts in a closed space. The first transparent support member is the portion from which the image can be seen' and the second support member has substantially the function of covering and supporting the device to provide a sufficient mechanical resistance. The main problem with these devices is that they quickly lose their luminescent properties after absorbing moisture. The lifespan of these devices has been reduced from thousands or tens of thousands of hours without moisture to hours of exposure to the atmosphere. Even the fading mechanism of OLED function is not completely digested', but this phenomenon is likely to be attributable to the additional role of the unsaturated bond of water molecules and organic mixtures on the one hand, and water and The reaction of the electrode, especially the metal due to the pole. The main route for water to enter the OLED is the perimeter seal of the two supports, which is typically carried out using a glue with a water permeable epoxy; the support is made of a polymer material (which is always water permeable, Even when there is a difference in water permeability between different materials, water can additionally penetrate the supports or be released from the organic material of the electroluminescent double layer. The solution to the problems caused by water entering an OLED is the subject of many patent publications, and the literature proposes different solutions. U.S. Patent Nos. 5,693,956 and 5,8,74,8,04 disclose OLEDs made of impervious inorganic materials such as quartz or metal. In any case, these systems do not solve the problem of water being released by the OLED-forming material. International Application No. WO99/03 1 22 discloses the introduction of a gas such as decane, trimethylaluminum or triethylaluminum into the interior space of a ruthenium LED, which 1267317 (3) gases react rapidly with water. And it is harmless to the function of the device. However, this system is detrimental to industrial applicability. U.S. Patent Nos. 5,8,04,9,7, and 5,8,82,76, and the disclosure of WO 99/3, 568, the disclosure of which is incorporated herein by reference in its entire entire entire entire disclosure The second support member is used, and there is no clear explanation of the nature of the material of the getter or the exact construction method of the OLED containing the getter material. International Application No. W098/5 9356 by way of example adds the type of getter material used in the aforementioned documents, such as helium, lithium or calcium, or yttrium oxide, even in this case, it does not explain how to Stable materials are deposited on the second support or how the process of the OLEDs of these layers is compatible. In fact, the materials listed above are highly reactive with water and air and must be added to the point where they are deposited. These layers can be deposited on the support "on the production line", which is one of the process steps of the OLED, but this is not favored by the screen manufacturer because it complicates the process and requires special equipment to handle extreme activity. element. The preferred preference for OLEDs would be to accept from a foreign supplier that a moisture absorbing device is provided in the form of deposits on the second support and that the first support of the existing electroluminescent structure is present immediately Combination of pieces. In this case, there is a problem of how to prevent deposits from coming into contact with the entire period from the generation of the deposit to the use in the OLED; it is also necessary to consider the transport between different manufacturing sites, which means The need to use the reactants to maintain the passive atmosphere, but the very getter provides the package request for the object. However, this deposition and atmospheric protection are directly in the second energy and need to be added. It is best to have a gas-tight atmosphere of -6 - 1267317 (4), which will be significant. Increase the cost of the final screen. SUMMARY OF THE INVENTION It is an object of the present invention to provide a deposit of getter material that can be used immediately on an organic electroluminescent screen that overcomes the aforementioned problems associated with warehousing and shipping. This object is achieved according to the invention by a component which is formed by at least one glass or metal support, the edges of which are fixed to an atmospheric gas-tight member, and the support member facing the gas-impermeable member The central portion of the side has an alkali metal or alkaline earth metal or a deposit of oxides of these metals. Preferably, the gas impermeable member is a second support member having a metal or an oxide on a side facing the first support member. [Embodiment] As shown in Fig. 1, the assembly 10 according to the present invention is constituted by two rigid members which are substantially planar, gas-tight and fixed to each other in the peripheral region. At least one of the two members forms a support having a getter material deposit to be used as a second support for the OLED. In this figure, this support is designated by the numeral 11. A deposit of getter material is provided at a central position of the support member, the getter material being selected from an alkali metal or an alkaline earth metal or an oxide thereof; and hydrazine is preferred. After the deposit 13 is made on the support 11 , the support is fixed to the member 14 by a fixing mechanism 16 along a peripheral zone (shown in phantom in the figure and labeled 15). In the example of the metal member, the fixing machine 1267317 (5) is welded and in the case of the glass member is a low-melting glass paste. After the formation of this structure, the deposit 13 is wrapped in a sealed space without contact with the outside, and in this state it can be stored indefinitely or without a special container. When used by a 0 LED manufacturer, it is only necessary to cut along the line between 12 and 15 (one of these lines is shown in the figure) to remove the protective member 14 and obtain The support 11 with the deposit 13 can be used as a second support for the OLED at any time. In a preferred embodiment, members 1 1 and 14 in the previous figure are support members having a getter material deposit to be used as a second support for an OLED. This structure is shown in the form of a sectional view in Fig. 2. The assembly 20 is formed by two support members 21, 21', each of which is centrally located on the side thereof facing the other support member. A deposit carrying one of the getter materials described above. The two support members 2 1, 2 1 ' are fixed to each other by the same fixing mechanism 23 as the assembly 10 . In this example, the OLED support having the getter deposit is along the line between the fixed mechanism 23 and the deposit 2 2, 2 2 ', as in the line 11 - 1 in the figure 111-111', cut and obtained from component 20. Component 20 is preferred with respect to component 1 , because in this example two supports of the OLED are available from each support, so the throughput of the system can be multiplied. Figure 3 shows the basis The structural details of the inventive components are made simpler to use; the figure is exemplified by component type 20. The figure shows an enlarged view of the periphery of the assembly 30, which is supported by two support members 3 1 and 3 1 ' which are fixed to each other by a fixing mechanism -8-1267317 (6) 3 2, 3 2 ', And a deposit of getter material 3 3, 3 3 ' is provided on each support member. The two support members 31 and 31' are provided with grooves 34, 34' which are located on a line which cuts the two support members apart to separate them (i.e., the turns Γ-Γ and II- in Figures 1 and 2)这些); these grooves make it easier to separate the two support members, and if they are deep enough, they can be broken by bending along the line (especially on the glass support 3丨, 3丨's example), without the need for a cutting operation. In the assembly according to the invention, the deposit of getter material (13; 22'22'; 33, 33') can be obtained by evaporation in the case of metal deposits, and the metal deposit can be exposed by exposure It is converted into an oxide in an atmosphere of oxygen in pure oxygen or in an inert gas. Alternatively, a technique known as "physical vapor deposition" can be used, which is more commonly referred to as "sputtering", or a modified reactive sputtering technique, ie, the deposition step is an argon containing a small percentage of oxygen. The occurrence of these deposits is generally in the range of a fraction of a micron to a maximum of 10-20 micrometers. [Brief Description of the Drawings] The present invention will be described hereinafter with reference to the accompanying drawings. Wherein: Figure 1 shows a partially cut away component in accordance with the present invention; Figure 2 shows a cross-sectional view of the assembly in accordance with a preferred embodiment of the present invention; and Figure 3 shows a component of the components in Figures 1 and 2 Details of possible variations. -9- 1267317 (7) Main components comparison table 10 Assembly 11 Support 12 Central portion 13 Sediment 14 Member 15 Peripheral area 16 Fixing mechanism 20 Assembly 21 Support 2 1 5 Support 22 Sediment 225 Sediment 23 Fixing mechanism 30 Assembly 3 1 Support 3 1' Support 32 Fixing mechanism 33 Sediment 33?
