| titleOfInvention | Organic light emission diode and preparation method thereof |
| abstract | The invention relates to an organic light emission diode and a preparation method thereof. The diode is provided with a plurality of organic light emission units, wherein an electric charge generation layer is contained between two adjacent organic light emission units and comprises an N-type layer and a P-type layer; the P-type layer also comprises a first semiconductor oxide layer and a second semiconductor oxide layer, wherein the first semiconductor oxide layer and the second semiconductor oxide layer are successively laminated; the material of the N-type layer is obtained in a way that organic dopant is doped in electronic transmission materials so as to avoid a problem of dopant diffusion; the P-type layer is made of two types of semiconductor oxide materials which are laminated and arranged so as to be favorable for the transmission and the injection of electrons and holes. According to the above arrangement, electric charge separation efficiency and electron transmission efficiency are improved, the drive current of the whole organic light emission diode is lowered, light emission efficiency is improved, and light emission efficiency is higher even under the action of equivalent drive current. In addition, organic materials which are convenient for vacuum evaporation are selected to further lower the complexity of preparation technology. |
