Abstract
The utility model relates to an organic film electroluminescence screen, which belongs to the technical field of the film electroluminescence of a lighting device. The utility model comprises ITO conductive glass (1), a high vacuum vapor deposition hole injection layer (3), a hole transfer layer (4), an electronic transfer and lighting layer (5), an electronic injection layer (6), a rear electrode (7) and a metal sealing cover (8), wherein the side edge of the metal sealing cover (8) is stamped with a groove hole (9); the metal sealing cover (8) and the groove hole are respectively filled with different kinds of dry agents. The utility model is sealed by solidifying sealing glue of ultraviolet which is mixed with nanometer grade insulation powder under the environment of dry protection. Thus, the organic film electroluminescence screen can avoid deterioration and aging of functional organic materials brought by water content. Besides, the service life of the utility model can be largely improved.
Description
The utility model relates to a kind of organic thin film electroluminescent screen, and it belongs to the field of luminescent device, thin film electroluminescence, particularly a kind of organic thin film electroluminescent screen that has metallic sealed cover.This luminescent screen technology is simple, cost of manufacture is lower, owing to introduced the peripheral metallic sealed cover that has the groove cave, has nano level insulating powder with interior having sneaked into of crown cap in the groove cave with different drier and fluid sealant, can prevent effectively that the luminescent screen that causes because of moisture is aging, thereby had greatly improved the useful life of device.
Electroluminescence screen particularly organic thin film electroluminescent shields employed functional material, all be to adopt the different types of organic material of Vacuum Coating method evaporation, add that coatings is very thin, very easily be subjected to moisture effects and go bad, cause the accelerated ageing of organic thin film electroluminescent screen, the useful life of reducing device.Use metallic sealed cover, can completely cut off the good organic thin film layer of evaporation and contact, prevent airborne moisture effects with air; And evaporation good organic film absorbed, and the drier that air moisture that may be residual in the when encapsulation lid is filled in then can tegmentum absorbs, the another kind of drier of in the groove cave, filling, add to sneak in the fluid sealant and have the nanoscale insulating powder and have and stop atmosphere to enter function in the seal cover, thereby the rotten of functional organic material that makes the organic thin film electroluminescent screen can avoid causing because of moisture wears out, and the life-span of device is had greatly improved.
The metallic sealed cover that the utility model provides, be to be stamped to form with very thin sheet metal such as tinplate, anodised alloy aluminium flake or stainless steel substrates etc., the metallic sealed cover that material is very thin can enlarge the capacity in the lid, the loading of lid internal desiccant also can increase thereupon, and fluid sealant has been sneaked into to have the nanoscale insulating powder and can prevent further that the airborne moisture in sealing back from invading.
The purpose of this utility model provides a kind of organic thin film electroluminescent screen of metallic sealed cover, its seal cover that has enlarged capacity can be desiccant-filled morely, make the organic thin film electroluminescent screen have practical useful life, thereby can be widely used in various indicator lights, sign and character display screen.
The purpose of this utility model realizes by following manner:
The basic structure of organic thin film electroluminescent screen be on the transparent conductive surface of ITO electro-conductive glass with Vacuum Coating method different functional organic material layer on the evaporation according to this, form hole injection layer, hole transmission layer, electric transmission and luminescent layer respectively, electron injecting layer, Mg on the evaporation: Ag (10: 1) or Al etc. are as back electrode again.The metallic sealed cover periphery has the groove cave, fills different drier in the lid with in the groove cave.Handling affairs in the sealing of crown cap scribbles insulating barrier earlier, is in the same place with the ITO conductive glass seal with the ultraviolet light polymerization fluid sealant of sneaking into the nanoscale insulating powder, becomes spendable device.
Effect of the present utility model is because sheet metal is very thin, metallic sealed cover and crown cap periphery have the groove cave, different drier can absorb air moisture, fluid sealant has been sneaked into the nanoscale insulating powder, prolonged the road warp that air is invaded, can effectively prevent airborne moisture intrusion, improve the aging of organic thin film electroluminescent screen, increase the life-span of device.
The utility model is described in further detail below in conjunction with accompanying drawing, and wherein accompanying drawing is a structural representation of the present utility model.
Embodiment
Adopting commercially available thickness is the ITO electro-conductive glass (1) of 1.1mm, its sheet resistance is 10～20 Ω/mouths, after fully cleaning, on the transparent conductive surface (2) of ITO electro-conductive glass (1), with hole injection layer (3), hole transmission layer (4), electric transmission and luminescent layer (5), electron injecting layer (6) on Vacuum Coating method evaporation successively, vacuum degree is 10
-4The Pa magnitude, Mg on the evaporation: Ag (10: 1) is as back electrode (7) again, is tinplate about 0.1mm with the mechanical stamping method with thickness, anodic oxidation alloy aluminium flake or stainless steel substrates strike out metallic sealed cover (8), the periphery of lid has groove cave (9), and the outer ledge of groove cave (9) scribbles a layer insulating and drying in advance.Metallic sealed cover (8) is interior fills I type drier, and fills II type drier in groove cave (9), in protective atmosphere metallic sealed cover (8) and ITO electro-conductive glass (1) is sealed with sneaking into the ultraviolet light polymerization fluid sealant (10) with nanoscale insulating powder at last.
Claims (1)
1, a kind of organic thin film electroluminescent screen, the metallic sealed cover (8) that it comprises ITO electro-conductive glass (1), hole injection layer (3), hole transmission layer (4), electric transmission and luminescent layer (5), electron injecting layer (6), back electrode (7) and is filled with drier is formed, the contact position of ITO electro-conductive glass (1) and metallic sealed cover (8) seals with fluid sealant (10), it is characterized in that:
The periphery of 1. said metallic sealed cover (8) has groove cave (9), is stamped to form with the sheet metal about thick 0.1mm, and sheet metal comprises tinplate, anodised alloy aluminium flake and stainless steel substrates;
2. the drier that fill said metallic sealed cover (8) and groove cave (9) is respectively I type drier and II type drier;
3. said fluid sealant (10) is to sneak into the ultraviolet light polymerization fluid sealant with nanoscale insulating powder.
