The structure comprises an anode layer and a cathode layer, wherein both an illumination layer and an auxiliary electrode are positioned between the anode layer and the cathode layer; the anode layer consists of transparent anodes; the cathode layer consists of metal cathodes; the auxiliary electrode is communicated with the transparent anodes and consists of independent auxiliary electrode monomers; and each auxiliary electrode monomer is communicated with the transparent anodes. The auxiliary electrode monomers have the same shape or different shapes. The auxiliary electrode consists of a plurality of auxiliary electrode monomers; the auxiliary electrode arranged on the transparent anodes is changed into a macroscopic structure; by utilizing the characteristic of opaqueness of the auxiliary electrode, star-speckled patterns are formed, so that the OLED illumination panel becomes more attractive; and the size and the density of the auxiliary electrode are determined according to the potential drops of different parts on the illumination panel, so that the impedance of the anodes can be further reduced and then the brightness uniformity of the panel is improved.
Description
Technical field
The present invention relates to a kind of OLED illumination panel, belong to illumination panel manufacturing technology field.
Background technology
Existing OLED illumination panel is by the transparent anode layer, and luminescent layer and metallic cathode layer are formed, and said anode layer is made up of transparent anode; Said cathode layer is made up of metallic cathode; Because the resistance of transparent anode side is bigger, is about 10 Ω/, voltage drop is serious; General OLED face is luminous to be obvious more from the place voltage drop phenomenon far away of power supply supply, causes illumination panel that tangible brightness irregularities phenomenon is arranged.For improving the inhomogeneities of illumination panel brightness, people have proposed a lot of schemes, and all being basically increases to be communicated with said transparent anode on the transparent anode layer; And the auxiliary electrode that is interconnected between self because side's resistance of auxiliary electrode is less, is about 1 Ω/; Current voltage drop reduces; During energising, the impedance and the current voltage drop of the transparent anode of panel are reduced, brightness uniformity is improved.
In the prior art; The arrangement of the auxiliary electrode that increases is generally criss-cross and arranges; Be that auxiliary electrode is the network structure that is interconnected on the transparent anode layer, its underpart is communicated with said transparent anode, and top is positioned at luminescent layer; So whole auxiliary electrode is less along the thickness of thickness of illuminated direction, the effect of improving of counter plate brightness uniformity receives than limitations; In addition, because auxiliary electrode is opaque, light can't pass, therefore increase auxiliary electrode after, be positioned at the light that the luminescent layer of auxiliary electrode top sends and can't get into the transparent anode layer, the auxiliary electrode aesthetics that the criss-cross of original dullness is arranged is relatively poor.
Summary of the invention
In order to overcome existing OLED illumination panel brightness uniformity effect and the relatively poor deficiency of aesthetics, technical problem to be solved by this invention provides a kind of brightness uniformity and OLED illumination panel attractive in appearance taken into account.
The technical solution adopted for the present invention to solve the technical problems is: the OLED illumination panel; Comprise anode layer, cathode layer, all between anode layer and cathode layer, said anode layer is made up of transparent anode for luminescent layer and auxiliary electrode; Said cathode layer is made up of metallic cathode; Said auxiliary electrode is communicated with described transparent anode, said auxiliary electrode by each separately independently the auxiliary electrode monomer form, each auxiliary electrode monomer is communicated with described transparent anode; And, according to the size and the density of the voltage drop of different parts on illumination panel decision auxiliary electrode monomer.
Said auxiliary electrode monomer is of similar shape.
Said auxiliary electrode monomer has two or more shapes.
The invention has the beneficial effects as follows: auxiliary electrode of the present invention is made up of several auxiliary electrode monomers, and the lateral dimension of auxiliary electrode monomer generally can be greater than existing arrangement mode, can reduce anode impedance and improves the panel luminance uniformity; And; Can the auxiliary electrode of on transparent anode, arranging be become macroscopic structure, and be the structure that disperses, more be imbued with design; Utilize the opaque characteristic of auxiliary electrode to make pattern fragmentarily; Make the OLED illumination panel more attractive in appearance, also be convenient to size and density, with the further panel luminance uniformity of improving according to the voltage drop decision auxiliary electrode monomer of different parts on the illumination panel.

Embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
Like Fig. 1, Fig. 3 and shown in Figure 4; OLED illumination panel of the present invention comprises anode layer 4, cathode layer 1, and luminescent layer 2 and auxiliary electrode 3 are all between anode layer 4 and cathode layer 1, and said anode layer 4 is made up of transparent anode; Said cathode layer 1 is made up of metallic cathode; Said auxiliary electrode 3 is communicated with described transparent anode, said auxiliary electrode 3 by each separately independently auxiliary electrode monomer 5 form, each auxiliary electrode monomer 5 is communicated with described transparent anode.The auxiliary electrode that on transparent anode, arrange becomes macroscopic structure; And be the structure that disperses, more be imbued with design, the lateral dimension of auxiliary electrode monomer generally can be greater than existing arrangement mode; Can reduce anode impedance and improve the panel luminance uniformity; Utilizing the opaque characteristic people of auxiliary electrode is the pattern that produces fragmentarily, makes the OLED illumination panel more attractive in appearance, and; Can determine the size and the density of auxiliary electrode monomer according to the voltage drop of different parts on the illumination panel, with the further panel luminance uniformity of improving.
If will conveniently make, said auxiliary electrode monomer 5 can be of similar shape, and said shape can be ornamental stronger shapes such as heart, star, falcate.
If will further improve the uniformity of brightness, like Fig. 3 and shown in Figure 4, can be the size variation of single auxiliary electrode monomer 5, also can be change of shape, also can be variable density, the perhaps above combination that changes.
