METHOD AND APPARATUS FOR ENCAPSULATION OF AN ORGANIC LIGHT EMITTING DIODE

A substrate includes a plurality of OLED, each having a conductor layer. A coating is formed over the OLEDs, the coating comprises a first inorganic layer formed over the OLED structures and at least partially over each of the contact layers, a buffer layer over the first inorganic layer, a second inorganic layer over the buffer layer, wherein the buffer layer comprises a first inorganic interface layer in contact with the first inorganic layer, a second inorganic interface layer in contact with the second inorganic layer, and an organic layer sandwiched between the first and second inorganic interface layers. 一种基材，包括多个OLED，每个OLED具有导体层。在OLED上形成涂层，该涂层包括在OLED结构上和至少部分在每个接触层上形成的第一无机层、在第一无机层上的缓冲层、在缓冲层上的第二无机层，其中缓冲层包括与第一无机层接触的第一无机界面层、与第二无机层接触的第二无机界面层、以及夹在第一和第二无机界面层之间的有机层。
