Description of the invention: [Technical field to which the invention belongs] = is related to-a kind of organic electroluminescence display panel package junction plate seal = structure 1 single, easy-to-manufacture electric light return display surface [prior technology] = The technical point of the excitation light includes: self-luminous, DC low voltage (below ㈣⑽), high luminous efficiency, = to achieve color lions, work orders, low cost, temperature, and the first performance is less affected by temperature. Compared with liquid crystal displays, the advantages of organic electroluminescent display panels are: 在于 there is no viewing angle problem; (2) the thickness is thinner than that of liquid crystal displays; (3) the cost can be reduced during mass production, and the crystal display is less beautiful; ( 4) Response time is better than LCD; (5) Yes, it can display at low temperature, and the response speed of LCD is low at low temperature. Even though organic electro-excitation light is a current emerging technology, it is [very difficult] including: the difficulty of maintaining t 疋! And the luminous efficiency brought by large panels, and the problem of water encapsulation and service life caused by organic materials. 2. The unevenness of organic materials leads to the unevenness of luminescence, degree and color. Organic electro-excitation light is formed on a glass substrate with an indium tin oxide (ITG) film by vacuum thermal evaporation to form a variety of materials, and then a metal film is formed on top of the organic. Next, in order to prevent the life of organic electro-excitation light elements from being deteriorated by external water vapor, __material light (uv) is followed by ultraviolet light ^ and then dried__ Is the cover tightly combined with the surface substrate to block water vapor? Into. The average lifetime of the existing organic electroluminescent materials can reach more than 5 1245583 15, 000 small inches, which can already be applied to actual mass-produced goods. = Can completely stop water vapor and oxygen. 3 Please refer to US Pat. No. 6,717,052 for the structure and composition of the organic electroluminescence light-emitting panel, which is configured to cover the different configurations and combinations of curable adhesive material (^ 『沾” ⑼ 与 ^) and the barrier rib (rib), and glass. The substrate is tightly attached, which has the effect of slowing down the invasion of water vapor. The towel, the curable rubber material that prevents the invasion of water vapor is thick m-generally to meet the mass production of low temperature, short time hardening = conditions, need to go through UV light Or heat-cured solid to achieve the purpose of blocking the second ^. However, when the sealant is laminated, the curable rubber material needs to be carefully and quantitatively controlled in the coating measurement and coating position, the coating dose is too small. The package life of electromechanical excitation light components, but too much coating dose easily spills to the inside of the 7L pieces, the back-end module fits outside, J is abnormal, or the display area displays the daytime surface abnormality, which affects the problem of external waste; and the curable Overflow of glue In the glue state, the overflow area can not be controlled. In response to the above problems, most of the 70-piece structure design is more complicated to avoid the occurrence of overflow. Defines the height of the sealant. The quality of 7 refers to the sealant structure with a plate in Taiwan Patent Application No. 93120922. The cover can pass through the curable ^ wall (-use _ up and down; cover fruit: = resistance 2 = and the stop Glue groove (accommodate excess material and the working glue is to avoid the overflow of glue to the external guide of the component when the sealant is pressed. 6 1245583 Avoid the electrical properties of the external wires inside the component; however, this method is still difficult to avoid overflow The glue problem is caused only by the mastering of the overflow area. What's more, although the seal is made of a metal material, the ultraviolet light needs to be provided from the other side of the glass substrate 1, and the The wire will cause the solidification, the adhesive material will cause a shielding effect and cannot be completely cured, and it will also cause moisture or oxygen to enter and cause deliquescent or aging of the internal organic materials. In addition, the complicated process of the dispensing process is self-evident. Dispenser It is necessary to precisely control the difference between the position of the ejection pin ^ and the height of the substrate (Gap), so that the glue that is dispensed is maintained at the same π degree. However, in addition to the high-precision machine, the above-mentioned control parameters are also necessary. The error value of the machine and the gap between the upper and lower sealing substrates may be different after the alignment is pressed. The current error is to overcome: the time and cost consumed will greatly reduce the packaging structure of the organic electroluminescent display panel. In addition, in addition to the use of curable glue, it is difficult to solve the problem of glue overflow. The coating of ΓΙ 固 1 glue material is used to enclose the cover or the glass-based enclosure by dispensing. After the 'sealing of the organic electroluminescent display panel's hollow state' is easy to be broken due to external forces: structure, fa, etc. solve the problem of overflowing glue. Improper packaging in this hollow state or other factors cause fragmentation and yield. 'The inventor felt the above-mentioned shortcomings, researched and matched the use of & sub-principle, and made it easy to choose a bad plan and the right test, and finally came up with an invention that effectively improved the above-mentioned shortcomings.[Summary of the Invention] In July, the organic electro-excitation light with a simple structure and simple manufacture 7 1245583 m. Panel package structure: Loss = light == installation: W breaks the sibling and it affects the electrical properties of the external wires inside the component: Condition and yield compensation etc. The present invention provides a method which can be completely omitted to avoid overflow and process improvement, and the efficiency and productivity caused by it: Electrically excited light display panel packaging structure.铖 mint—The structure of the financial display panel of the financial and electrical machinery, including the glass-filled glass substrate with the organic electro-excitation light display unit formed thereon, and the cover and the glass substrate: , Adhesive film; Among them, the film is a conductive material with low hygroscopicity (1GW with Sture absQrptiQn) and high miscellaneous (_ of conductive materials, and the sheet is fully bonded to the glass, The cover film may be an adhesive film that requires ultraviolet or thermal curing or can be directly pasted without curing.…, The present invention provides an organic electroluminescent display panel packaging structure, and I 3 has organic electroluminescent The glass substrate on which the display unit is formed, a cover sealed with the glass substrate, and a double-sided adhesive film adhered between the cover of the glass substrate tray and the cover; wherein the glass substrate further includes The passivation layer on the organic electroluminescent display unit 'completely covers the optical and electrical return light unit; the adhesive film has low moisture absorption (Uww moisture absorption) and high plasticity. ) Of Electroconductive! 245,583 material, and a sheet to form a comprehensive bonding the glass substrate and the cover, the film can be no turning of the adhesive film can be directly or oil is needed or ultraviolet.

Alternatively, the adhesive film 30 may be an epoxy resin with high adhesion. As shown in FIG. 1A, the adhesive film 30 is a fully-closed design for bonding the broken glass substrate 10 and the cover 20. Or, as shown in FIG. 1B, the adhesive film 30 includes at least one fine opening 31 and is spread on it in a non-closed design to adhere the glass substrate 10 and the cover 20; It is a principle to increase the mechanical strength of the packaging structure of the organic electroluminescent display panel. In addition, the light emitting surface of the packaging structure of the organic electroluminescent display panel can be transmitted through the cover 20 or the glass substrate 10, and when transmitted through the glass substrate 10, the cover 20 can be a glass material, a metal material, or a ceramic Made of materials, and the transparency of the adhesive film 30 is not required; when the cover 2011 1245583 is made of glass material, the adhesive film 30 needs to have (hlgh Hght transmission), so that the organic electricity pm, #t ± 11 emitted light will not be shielded; when the cover n # +, > day inch, if made of this genus or ceramic material, the win film 30 It can relatively control its required light transmittance.
