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 space and a capping layer. |

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 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. |
