Abstract
The utility model relates to an organic electroluminescent display device which comprises a glass base plate, a rear cover, sealing agent as well as an organic luminescent layer and drying agent that are encapsulated between the glass base plate and the rear cover, wherein the sealing agent is used for bonding the glass base plate and the rear cover; and the rear cover is provided with a slot used for containing the sealing agent. As the rear cover is provided with the slot used for containing the sealing agent, the contact area between the sealing agent and the air can be effectively reduced, the risk that the device is corroded by humidity and oxygen can be effectively reduced, the service life of the organic display device is prolonged, and the whole thickness of the device is effectively reduced.
Description
Technical field
The utility model relates to a kind of organic elctroluminescent device, particularly a kind of organic elctroluminescent device that improves sealing.
Background technology
The Organic Light Emitting Diode of self-luminous form in recent years, (OLED) causes that as flat-panel display device people pay close attention to widely.The life-span of OLED device is depended on selected organic material on the one hand, also depends on the method for packing of device on the other hand; For organic electronic device, especially OLED wants strict stopping to enter organic substance and the electrode that device inside touches sensitivity from the moisture and the oxygen of surrounding environment.Because in organic light emitting apparatus inside, the existence of moisture or oxygen causes the degeneration or the inefficacy of its characteristic easily, though the moisture of trace also can the organifying compound layer and electrode layer peel off, cause producing blackspot.Thereby, being inhibited for making the degeneration and the inefficacy of OLED in the long-term work process, steady operation reaches enough life-spans, the barrier of encapsulating material is proposed the requirement of strictness.Nowadays commonly used is to adopt etching glass cover or metal shell to cover organic luminous component, around the organic light emission part, apply sealant, and moisture absorbent is placed on wherein, with moisture-barrier and oxygen, perhaps before arriving organic substance, intercept by gettering material at least, thus the life-span of prolongation organic light emitting apparatus.The shortcoming of common this method is that the width of sealant is wayward after the pressing; The relative area that sealant is exposed in the atmosphere is bigger, makes moisture penetrate device and the possibility that weathers increases; The device integral thickness is thicker.
Therefore, need a kind of organic elctroluminescent device of design effectively to overcome above-mentioned technical problem.
The utility model content
The purpose of this utility model provides a kind of organic elctroluminescent device that improves sealing, and it can effectively reduce sealant and air contact area, reduces the intrusion of environment moisture, effectively reduces the device integral thickness.
To achieve these goals, the utility model adopts following technical scheme:
A kind of organic elctroluminescent device, comprise glass substrate, bonnet, sealant and be packaged in glass substrate and bonnet between organic luminous layer, bonding glass substrate of described sealant and bonnet, described bonnet is provided with the wire casing of accommodating sealant.
Described organic elctroluminescent device also comprises the drier that is packaged between glass substrate and the bonnet.
Compared with prior art, the utlity model has following advantage: accommodate sealant by on bonnet, offering wire casing, can effectively reduce sealant and air contact area like this, can effectively reduce the risk that device is corroded by moisture, oxygen, effectively improve the life-span of organic display spare, simultaneously, effectively reduce the device integral thickness.
Description of drawings
Fig. 1 is the structural representation of prior art organic elctroluminescent device;
Fig. 2 improves the structural representation of the organic elctroluminescent device of sealing for the utility model;
Fig. 3 improves the bonnet schematic diagram of the organic elctroluminescent device of sealing for the utility model;
Wherein: 1 is glass substrate; 2 is organic luminous layer; 3 is drier; 4 is bonnet; 40 is wire casing; 5 is sealant.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
See also shown in Figure 1, organic elctroluminescent device mainly comprises glass substrate 1, is arranged at organic luminous layer 2, bonnet 4, drier 3 and sealant 5 on the glass substrate 1 in the prior art, and glass substrate 1 and bonnet 4 are sealed in organic luminous layer 2 and drier 3 in it.
See also Fig. 2 and shown in Figure 3, the organic elctroluminescent device that the utility model improves sealing is offered wire casing 40 in bonnet 4 and sealant 5 bonding places on the basis of existing technology, wire casing 40 can be accommodated some or all of sealant 5, make sealant 5 and air contact area reduce, can effectively reduce the risk that device is corroded by moisture, oxygen, the life-span of organic display spare can be effectively improved like this, simultaneously, the device integral thickness can also be effectively reduced.
The utility model improves the organic elctroluminescent device of sealing after encapsulation pressing, sealant cures, can reach the sealant thickness of minimum ingress of air, and the sealant of stable and consistent encapsulation track and shape, and don't influence the required sealant adhesive strength of device.Finally reach raising device lifetime and the device effect of slimming more.
