It provides an OLED module 800 comprising a.

Here, the OLED panel 100 may be formed of the substrate layer 10, the anode layer 20, the organic material layer 30, the cathode layer 40, and the encapsulation layer 50.

In general, in the OLED panel 100, when the polymer organic material is used, the organic material layer 30 generally has a two-layer structure of a light emitting layer and a hole injection layer. In contrast, when the low molecular organic material is used, the organic material layer 30 is used. Silver generally has a multilayer structure such as a five-layer structure of a hole injection layer, a hole transport layer, a light emitting layer, a hole block layer, and an electron transport layer.

In addition, it is preferable that the substrate layer 10 is generally made of glass, and the grid on the substrate is additionally formed to contact the anode layer 20 so that the anode layer 20 is wired to the driving device for illumination. When connected to the negative electrode may serve to lower the electrical resistance value of the anode layer (20). The grid is usually a metal having a smaller resistance value than the anode layer 20, and includes chromium (Cr), copper (Cu), molybdenum (Mo), nickel (Ni), aluminum (Al), silver (Ag), or gold (Au). Can be The grid may be formed by a process such as deposition on the substrate layer 10, application of photosensitive photoresist, development, etching, or the like.

The anode layer 20 is an anode electrode corresponding to the anode of the OLED panel 100, and the material is indium tin oxide (ITO) and indium zinc oxide having low surface resistance and good permeability. IZO) or a transparent conductive material such as aluminum zinc oxide (AZO). By forming the anode layer 20 on the grid, the resistance of the anode layer 20 is lowered, and then the power consumption and driving voltage are lowered when driving the OLED panel by connecting with an external driving circuit, thereby improving the electrical characteristics of the device. have. Typically, the anode layer 20 may be formed by a chemical vapor or atomic layer deposition method or using a deposition process such as sputtering.

If necessary, the patterning is carried out by laser cutting, and by selective chemical vapor deposition, for example through-mask deposition, integral shadow masking, as described in US Pat. Nos. 5,276,380 and 6,221,563 and EP 0 732 868. It may be achieved through a number of known methods, including but not limited to integral shadow masking.

The magnetic material used for the magnetic layer 200 of the present invention is preferably a ferromagnetic material such as Fe. When the ferromagnetic material, Fe, is laminated in a multilayer of thin films, it serves to magnetically block external magnetic fields. In other words, the magnetic flux from the outside can not enter the ferromagnetic material, it is magnetically insulated from the external magnetic field.

On the other hand, the magnetic layer 200 is preferably a magnetic film printed on the OLED panel 100, or a magnetic film bonded on the OLED panel. The magnetic layer 200 may be any material as long as it can generate a magnetic force to be coupled to the base panel 900 to be described later by a magnetic force. For example, it is also possible to use a rubber-like magnet used for attaching advertisements to refrigerators at home.

In addition, the first anode electrodes 310 and 330 and the first cathode electrode 320 may be formed by depositing or printing the magnetic layer 200 or by attaching an electrode tape.
