Abstract
The utility model relates to an organic electroluminescent device with a radiating device. The organic electroluminescent device comprises a glass substrate and an organic luminescent layer located above the glass substrate; and a radiating device is attached below the glass substrate. The utility model has the advantages that: as the radiating device is arranged on the lower part of the organic electroluminescent device, the heat generated by the organic electroluminescent device in the working process can be quickly guided and radiated, thereby reducing the working temperature of the organic electroluminescent device, prolonging the service life and improving the performance.
Description
Technical field
The utility model belongs to OLED (organic electroluminescent LED) technical field, relates in particular to a kind of organic electroluminescence device.
Background technology
Along with the OLED technical development, OLED is the direction of development in the large scaleization of display application and illumination application, but along with organic electroluminescence device (comprises display device and illuminating device, down with) size becomes greatly driving or light and has big calorimetric in the process and take place, the organic electroluminescence device temperature is raise, especially at lighting field, become the problem that commercial applications must overcome.Because organic electroluminescence device mainly is made up of organic material, if the temperature of organic electroluminescence device raises, can make the organic material sex change, influence the performance of life-span and performance.Therefore, if can reduce working temperature, will have very great help to prolonging its life-span and improving the performance performance with organic electroluminescence device driving or light the heat derivation of sending in the process.
The utility model content
The purpose of this utility model is in order to reduce existing deficiency as heat radiation difficulty in the organic electroluminescence device course of work of display device or illuminating device, to have proposed a kind of organic electroluminescence device that has heat abstractor.
To achieve these goals, the technical solution of the utility model is: a kind of organic electroluminescence device that has heat abstractor, comprise glass substrate and the organic luminous layer that is positioned at the glass substrate top, it is characterized in that the attached below of described glass substrate has heat abstractor.
Above-mentioned heat abstractor is a metal fin.
Above-mentioned heat abstractor is a radiating tube.
The beneficial effects of the utility model are: because the below of organic electroluminescence device has heat abstractor, therefore can fast the heat guiding that produces in the organic electroluminescence device course of work be distributed, therefore reduced the working temperature of organic electroluminescence device, can prolong its life-span and improve its performance.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1: as shown in Figure 1, a kind of organic electroluminescence device that has heat abstractor adopts the conventional package structure among the figure, glass substrate 1 and encapsulation cover plate 4 form a confined space by encapsulation UV (ultraviolet) resin 3 encapsulation backs, organic luminous layer 2 is positioned at confined space and is in the top of glass substrate 1, understand the utility model for the ease of those of ordinary skill in the art, omitted the anode layer supporting among the figure with organic luminous layer 2, other constitutes the concrete structure of this luminescent device cathode layer and resilient coating etc., because these concrete structures can adopt various structure of the prior art, can not influence those of ordinary skill in the art to understanding of the present utility model, encapsulation drier 5 is positioned at confined space and is close to the below of encapsulation cover plate 4.Many group heat radiation heat pipes 6 are close to the below of glass substrate 1 as the heat abstractor of present embodiment.
The concrete structure of heat radiation heat pipe 6 as shown in Figure 5, heat radiation heat pipe 6 comprises evaporation ends 61, condensation end 62, capillary brass pipe 63 and shell 64, solid arrow represents to dispel the heat liquid in the heat pipe 6 under the capillarity effect among the figure, flow to evaporation ends 61 from condensation end 62, dotted arrow represents that evaporation ends 61 evaporation of liquid heat absorption back is to condensation end 62 diffusions.Heat radiation heat pipe 6 is to rely on the hydraulic fluid phase change of self inside to realize the heat conduction original paper of heat conduction.The heat radiation heat pipe 6 an end be evaporation ends 61, the other end is a condensation end 62, the heat radiation heat pipe 6 form by highly purified oxygen-free copper pipe and copper mesh, in fill an amount of liquid as hydraulic fluid.Evaporation ends 61 flashes to gas phase with hydraulic fluid, air-flow flows to condensation end 62 through the capillary brass pipe 63 in the hollow pipeline, after the cooling working fluid is condensed into liquid phase, the capillary structure that evaporation ends 61 relends capillary brass pipe 63 formation sucks back evaporation ends 61 with liquid, so finish to inhale and put circulation, promptly pass through the liquid phase and the vapour phase variation of liquid substance and circulate more than, carry out fast, can be under certain temperature difference the heat that produces in the organic electroluminescence device course of work be conducted endlessly and come, play cooling heat dissipation effect organic electroluminescence devices.
Embodiment 2: as shown in Figure 2, a kind of organic electroluminescence device that has heat abstractor adopts thin-film packing structure among the figure, organic luminous layer 2 is positioned at the top of glass substrate 1, thin-film encapsulation layer 7 is positioned at the top of organic luminous layer 2, and its edge is close on the glass substrate 1 organic luminous layer 2 encapsulation.Understand the utility model for the ease of those of ordinary skill in the art, omitted equally among this figure that other constitutes the concrete structure of this luminescent device with supporting anode layer, cathode layer and the resilient coating etc. of organic luminous layer 2, because these concrete structures can adopt various structure of the prior art, can not influence those of ordinary skill in the art to understanding of the present utility model.Heat radiation heat pipe 6 is close to the below of glass substrate 1 as the heat abstractor of present embodiment.
Because the structure of the heat radiation heat pipe 6 in the present embodiment and principle with embodiment 1, therefore no longer describe in detail.
Embodiment 3: as shown in Figure 3, the difference of present embodiment and embodiment 1 is that the heat abstractor of present embodiment adopts metal fin 8, these metal fins 8 can be the metal of good heat dispersion performance such as aluminium, silver, copper, gold, generally make lattice-shaped to increase area of dissipation, therefore other parts are not described in detail in identical with embodiment 1.
Embodiment 4: as shown in Figure 4, the difference of present embodiment and embodiment 2 is that the heat abstractor of present embodiment adopts metal fin 8, these metal fins 8 can be the metal of good heat dispersion performance such as aluminium, silver, copper, gold, generally make lattice-shaped to increase area of dissipation, therefore other parts are not described in detail in identical with embodiment 2.
