Background technology
OLED (Organic Light Emitting Diode Organic Light Emitting Diode) is the illumination and the display unit of a new generation, it is by being clipped in luminous organic material between transparent anode and the metallic reflection negative electrode, organic film is applied voltage to carry out luminous, one is that single face is luminous for OLED, if can obtain better effect by lighting at two sides at some particular application display, the OLED display of one double-side or by the metallic reflection cathode material is replaced with the ITO transparent material, other luminescence units of stack are realized on the OLED luminescent layer, these two kinds of methods all can be brought a lot of difficulties to OLED making or OLED driving, can significantly increase cost, one comprises luminescent layer existing OLED display unit, transparent anode, organic function layer and metallic cathode reflector, described transparent anode covers the one side of luminescent layer, organic function layer covers the another side of luminescent layer, the metallic cathode reflector covers on the organic function layer, and the metallic cathode reflector need be connected with auxiliary electrode.
The utility model content
The purpose of this utility model is the OLED display that the overcomes present lighting at two sides higher relatively shortcoming of cost when making, and a kind of OLED display unit of double-side is provided.
The utility model solves its technical problem, the technical scheme that adopts is, the OLED display unit of double-side, comprise luminescent layer, organic function layer and transparent anode, described transparent anode covers the one side of luminescent layer, and organic function layer covers the another side of luminescent layer, it is characterized in that, also comprise thin metallic cathode and bar palisade metallic cathode, described thin metallic cathode covers on the organic function layer, and bar palisade metallic cathode is arranged on the thin metallic cathode.
Concrete, described thin metallic cathode and/or bar palisade metallic cathode adopt aluminum cathode or magnesium silver alloy negative electrode.
Further, the thickness of described thin metallic cathode is 10 * 10
-10～100 * 10
-10M; The thickness of described palisade metallic cathode is 1000 * 10
-10～2000 * 10
-10M.
Concrete, described palisade metallic cathode is connected with auxiliary electrode.
The beneficial effects of the utility model are, OLED display unit by above-mentioned double-side, adopt the metallic cathode identical with the prior art material, its manufacture craft does not almost change, only one deck in the prior art is replaced with the thin metallic cathode of one deck and one deck bar palisade metallic cathode in thicker metallic cathode reflector relatively, save cost, because thin metallic cathode is very thin and intimate transparent, therefore can printing opacity, and bar palisade metallic cathode is arranged on the thin metallic cathode, can be when being connected with auxiliary electrode, reduce impedance and guarantee bonding strength, in addition because bar palisade metallic cathode is the bar palisade, can printing opacity between two bar grid, reached the effect of double-side, if be the front of the OLED display unit of double-side with the transparent anode, then it can change the luminous intensity at the back side of the OLED display unit of double-side by the coverage rate of bar grid on thin metallic cathode of adjusting bar palisade metallic cathode.
Description of drawings
Fig. 1 is the example structure schematic diagram;
Wherein, 1 is transparent anode, and 2 is luminescent layer, and 3 is organic function layer, and 4 are thin metallic cathode, and 5 is bar palisade metallic cathode.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail.
The OLED display unit of double-side described in the utility model is covered the one side of luminescent layer 2 by transparent anode 1, organic function layer 3 covers the another side of luminescent layer 2, thin metallic cathode 4 covers on the organic function layer 3, bar palisade metallic cathode 5 is arranged on the thin metallic cathode 4 to be formed, because it only replaces with the thin metallic cathode 4 of one deck and one deck bar palisade metallic cathode 5 in thicker metallic cathode reflector relatively with one deck in the prior art, saves cost.
Embodiment
