Technical field
The present invention relates to a kind of oled panel, the auxiliary electrode arrangement of especially this oled panel its transparent anode on microcosmic.
Background technology
Existing OLED illumination panel is usually by anode layer, luminescent layer and cathode layer are formed, described anode layer is made of transparent anode, described cathode layer is made 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 more of power supply supply, causes illumination panel that tangible brightness irregularities phenomenon is arranged.
For improving the unevenness 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, auxiliary electrode is made by conducting metal, side's resistance is less, be about 1 Ω/, current voltage drop reduces, during energising, the impedance and the current voltage drop of the transparent anode of panel are reduced, and brightness uniformity is improved.The OLED illumination panel mostly is rectangle, anode layer also is a rectangle, in the prior art, the auxiliary electrode arrangement that it adopts is generally grid square shape and arranges, be that described auxiliary electrode is vertical bar shaped, evenly the compartment of terrain is arranged on the rectangle anode layer of transparent anode formation, and auxiliary electrode is communicated with transparent anode, and each bar auxiliary electrode is parallel to wherein limit of rectangle anode layer.
But 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 enter the transparent anode layer, the light-emitting area of counter plate has adverse influence.
Summary of the invention
Unreasonable in order to overcome existing OLED illumination panel auxiliary electrode arrangement, the deficiency that light-emitting area is less, technical matters to be solved by this invention provide a kind of OLED illumination panel auxiliary electrode arrangement that can increase light-emitting area at assurance whole front panel brightness uniformity simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: OLED illumination panel auxiliary electrode arrangement, the OLED illumination panel comprises the auxiliary electrode on the rectangle anode layer, auxiliary electrode is communicated with the transparent anode that constitutes the rectangle anode layer, auxiliary electrode is made up of the auxiliary electrode bar of vertical bar shaped, each auxiliary electrode bar is arranged on the rectangle anode layer equably, size according to the acute angle angle α between the long limit of each bar auxiliary electrode bar and this rectangle anode layer, all the auxiliary electrode bar is divided into one group or two groups, acute angle angle α equates this angle α=30 °～60 ° in described each group.
Further be described angle α=40 °～50 °.
Further be described angle α=45 °.
Described whole auxiliary electrode bar can be divided into two groups, wherein one group and another group square crossing layout.
The invention has the beneficial effects as follows: simply change the arragement direction of auxiliary electrode on the rectangle anode layer, on the rectangle OLED illumination panel that just can make in identical size, under the suitable situation of brightness uniformity, bigger light-emitting area is arranged, thereby improved luminescence efficiency.
