Description
Technical field
The utility model relates to a kind of organic electro-luminescent display component structure, and particularly relevant for a kind of organic electro-luminescent display component structure that on cover plate, forms irrigation canals and ditches with the glue of avoiding overflowing.
Background technology
Along with the raising of organic electro-luminescent display element brightness to reach the demand of use; the stability of element operation and persistence are to reach the required problem that faces of volume production; airborne aqueous vapor and oxygen can cause the photodestruciton reaction of metallic film deterioration and organic luminous layer; because the existence of oxygen provides the path that free radical (radical) forms in the organic luminous layer; except meeting and organic luminous layer form the phosphinylidyne group (carbonyl) with the two keys of carbon oxygen; the generation of phosphinylidyne group not only can reduce the luminescence efficiency of organic luminous layer, also can make molecular scission cause component life to shorten phenomenon simultaneously.Therefore, many companies and researcher are devoted to the improvement of three directions such as membrane structure, material, packaging technology in the encapsulation development of organic electro-luminescent display element.And focus at element internal in the research direction of packaging technology and to insert hygroscopic agent or on component structure, to plate one or more layers diaphragm.
Insert the hygroscopic agent aspect in element internal, Idemitsu Kosan proposes a kind of method for packing patent (No. the 5962962nd, United States Patent (USP)) in nineteen ninety-five, in the process of encapsulation, inertia, the grease that dewaters is poured into element internal, and sneak into hygroscopic agent in grease.Pioneer company then proposed another kind of method for packing patent (No. the 5882761st, United States Patent (USP)) in 1996, in the process of encapsulation, use has the metal cover board of groove, and at cover plate groove stickup hygroscopic agent, the aqueous vapor that enters element internal by the hygroscopic agent adsorption and permeation is to promote the life-span of element.
In addition, and on component structure, plate a purpose to several layers of diaphragm, penetrate into element internal in order to the aqueous vapor that blocks external environment fully.In this regard; the diaphragm coating of organic material and inorganic material was all once inquired into; for example motorola inc proposes a kind of protective seam patent (No. the 5811177th, United States Patent (USP)) in nineteen ninety-five, plates inert metal, inorganic protective film and resin capping on component structure.
Please refer to Fig. 1, it is the structural representation of known organic electro-luminescent display component package.The volume production method for packing of known organic electro-luminescent display element, mainly under inert gas environment, one organic electro-luminescent display panel 100 is provided, have an organic electro-luminescent display element 102 on it, then ultraviolet sclerotic type glue is coated organic electro-luminescent display element 102 panel 100 surfaces all around and go up to form frame glue 104 with syringe.One cover plate 106 is provided afterwards again; cover plate 106 and panel 100 are carried out contraposition pressing and ultraviolet action of shining; by 104 sclerosis of the frame glue between cover plate 106 and the panel 100 cover plate 106 and substrate 100 are pasted, be not subjected to the erosion of water in air gas or oxygen with protection organic electro-luminescent display element 102 inside.
Yet because frame glue is macromolecular material, and can't block the infiltration of external environment aqueous vapor fully, so that the life-span of organic electro-luminescent display element can't reach commercial demand.
In addition, when frame glue was coated with, the control of its width and shape was difficult for, and it is wide too slightly or too thin glue usually can to occur.If glue is wide too thick, regular meeting causes the phenomenon of the glue that overflows, the difficulty when causing the subsequent module sliver.If glue is wide too thin, then can cause adhesion deficiency or water-resisting property variation between cover plate and the panel.
The utility model content
The purpose of this utility model is to propose a kind of organic electro-luminescent display component structure, and the scope by the coating of the irrigation canals and ditches structural limitations frame glue on the cover plate is wide too slightly or too thin problem to improve glue, promotes the water-resisting property of adhesion and frame glue between cover plate and the panel.
For reaching above-mentioned purpose of the present utility model, a kind of organic electro-luminescent display component structure is proposed, comprise a panel, an organic electro-luminescent display element, a frame glue and a cover plate.The organic electro-luminescent display arrangements of components is on panel, and cover plate is disposed on the organic electro-luminescent display element and by frame glue and panel stickup, and frame glue is disposed between panel and the cover plate, and be distributed in the organic electro-luminescent display element around.Wherein, have at least one irrigation canals and ditches structure on the edge of cover plate, in order to limit the scope of frame glue coating, it is wide too slightly or too thin problem to improve glue, promotes the water-resisting property of adhesion and frame glue between cover plate and the panel.
Among the utility model first embodiment, the irrigation canals and ditches that have a continuous frame shape structure on the edge of cover plate can limit the scope of frame glue coating, and the multi-level groove structure on the cover plate can avoid weighing wounded organic electro-luminescent display element and the demand that reaches the configuration hygroscopic agent.And among the utility model second embodiment, the irrigation canals and ditches that have the frame shape structure of an interior ring and an outer shroud on the edge of cover plate, can limit the scope of frame glue coating, and the multi-level groove structure on the cover plate can avoid weighing wounded organic electro-luminescent display element and the demand that disposes hygroscopic agent.Irrigation canals and ditches on the cover plate and the collocation of groove structure at many levels can be so that the reliability of organic electro-luminescent display component package greatly improve.
