Abstract:
1. A method of encapsulating an organic light-emitting diode (OLED) device, comprising: positioning a first mask over a substrate, the first mask having a first size; depositing a first encapsulating layer on an OLED device disposed on the substrate with the first mask, wherein the positioning the first mask over the substrate is performed in a first process chamber and the depositing the first encapsulating layer on an OLED device disposed on the substrate is performed in the first process chamber; positioning a second mask over the substrate, the second mask having a second size; depositing a buffer layer on the first encapsulating layer and the OLED device with the second mask; positioning a third mask over the substrate, the third mask having a size equal to the first size; and depositing a second encapsulating layer on the buffer layer, the first encapsulating layer, and the OLED device with the first mask.
