摘要:
Organic light emitting devices are disclosed that use a micro electromechanical system (MEMS) structure to enable a pixel and pixel array wherein each pixel contains a MEMS and an OLED element. A MEMS structure is used for switching the OLED element. These OLED/MEMS pixels can be fabricated on flex circuit, silicon, as well as other inorganic materials. They can be fabricated in a large array for developing a 2-dimensional display application and each pixel can be addressed through conventional matrix scanning addressing scheme. The ability of fabricating these OLED/MEMS pixels on flexible organic substrates as well as other rigid substrates enables wider selection of substrate materials for use with different applications.

A method of processing a multilayer film is provided. The method includes providing a substrate film having a substrate film first surface and a substrate film second surface. The method also includes providing a barrier layer adjacent to the substrate film second surface. The barrier layer has at least one opening allowing fluid communication between the substrate film and an outer surface of the barrier layer. Further, the method includes contacting the substrate film first surface with a first reactant and finally contacting the outer surface of the barrier layer with a second reactant, said second reactant being reactive with said first reactant. The method of contacting the substrate film first surface to the first reactant and contacting the outer surface of the barrier layer to the second reactant is carried out under conditions under which reaction between said first reactant and the second reactant results in a formation of a reaction layer.
