| 发明名称 | Patterning method for OLEDS | ||
| 摘要 | Methods of fabricating a device having laterally patterned first and second sub-devices, such as subpixels of an OLED, are provided. Exemplary methods may include depositing via organic vapor jet printing (OVJP) a first organic layer of the first sub-device and a first organic layer of the second sub-device. The first organic layer of the first sub-device and the first organic layer of the second sub-device are both the same type of layer, but have different thicknesses. The type of layer is selected from an ETL, an HTL, an HIL, a spacer and a capping layer. | ||

| 主权项 | 1. A method of fabricating a device having at least laterally patterned first and second sub-devices, the method comprising: depositing via organic vapor jet printing (OVJP) a first organic layer of the first sub-device and a first organic layer of the second sub-device; wherein the first organic layer of the first sub-device and the first organic layer of the second sub-device have different thicknesses; wherein the first organic layer of the first sub-device and the first organic layer of the second sub-device have the same material composition; and wherein the first organic layer of the first sub-device and the first organic layer of the second sub-device are both the same type of layer, and wherein the type of layer is selected from an ETL, an HTL, an HIL, a spacer and a capping layer. | ||
