Abstract
The utility model discloses an OLED lighting panel capable of emitting light on two sides, including an anode layer and a cathode layer, a light-emitting layer and an auxiliary electrode are all arranged between the anode layer and the cathode layer, the anode layer is composed of transparent anodes, the cathode layer is composed of metal cathodes, the auxiliary electrode is communicated with the transparent anodes, and the cathode layer is made of transparent metallic material. Because the cathode layer is made of transparent material, the light emitted by the light-emitting layer can be simultaneously penetrated through the transparent anode layer and the transparent cathode layer so as to implement lighting on two sides. The OLED lighting panel is mainly used for situations of indoor illumination or other special lighting requirement.
Description
Technical field
The utility model relates to a kind of OLED illumination panel, belongs to illumination panel manufacturing technology field.
Background technology
Existing OLED illumination panel, by the transparent anode layer, luminescent layer and metallic cathode layer are formed, described anode layer is made of transparent anode, and described cathode layer is made of metallic cathode, because the resistance of transparent anode side is bigger, be about 10 Ω/, voltage drop is serious, and general OLED face is luminous to be obvious more from the place voltage drop phenomenon far away more 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, basically all be on the transparent anode layer, to increase to be communicated with described transparent anode, 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, cathode layer is opaque, and light can't pass, so the light that luminescent layer sends can only appear from anode layer, and promptly single face is luminous.
The utility model content
In order to overcome the existing luminous deficiency of OLED illumination panel single face, technical problem to be solved in the utility model provides a kind of OLED illumination panel of energy double-side.
The technical scheme that its technical problem that solves the utility model adopts is: the OLED illumination panel, comprise anode layer, cathode layer, luminescent layer and auxiliary electrode are all between anode layer and cathode layer, described anode layer is made of transparent anode, described cathode layer is made of metallic cathode, described auxiliary electrode is communicated with described transparent anode, and described cathode layer is made of transparent metal material.
Described anode layer periphery conduction is connected with the metal ring layer.
The beneficial effects of the utility model are: cathode layer is also made of transparent material, therefore the light that is sent by luminescent layer can appear by transparent anode layer and transparent cathode layer simultaneously, realize double-side, the utility model is mainly used in room lighting has the occasion of special lighting needs with OLED illumination panel or other.
Description of drawings
Fig. 1 is the structural representation of existing OLED illumination panel.
Fig. 2 is the structural representation of the utility model OLED illumination panel.
Fig. 3 is the structural representation of the transparent anode of the utility model OLED illumination panel.
Be labeled as 1-cathode layer, 2-luminescent layer, 3-auxiliary electrode, 4-anode layer, 5-metal ring layer among the figure.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As depicted in figs. 1 and 2, OLED illumination panel existing and of the present utility model includes anode layer 4, cathode layer 1, luminescent layer 2 and auxiliary electrode 3 are all between anode layer 4 and cathode layer 1, described anode layer 4 is made of transparent anode, described cathode layer 1 is made of metallic cathode, described auxiliary electrode 3 is communicated with described transparent anode, but existing its cathode layer 1 of OLED illumination panel is lighttight, and OLED illumination panel of the present invention its cathode layer 1 be printing opacity, that is it uses transparent metal material to make.
As shown in Figure 3, because the making of transparent anode has been a prior art, therefore, make transparent cathode and do not have technical difficulty, just when needs reduce impedance with increase brightness, can be connected with metal ring layer 5 in described anode layer 4 periphery conductions, metal ring layer 5 material that general employing is opaque, impedance is lower, this metal ring layer 5 also can be used as the decoration of whole oled panel simultaneously.
