“…Another approach based on conventional lithographic patterning takes advantage of the orthogonality between highly fluorinated LEPs and standard photoresists. [15,16,17] However, the choice of materials for these traditional lithography approaches is limited, thus restricting the flexibility and performance of available OLED architectures.…”

Together with "back plane" electronic components and highly efficient "front plane" light-emitting devices, the successful implementation of pixel patterning is a key requirement for the success of organic light-emitting diode (OLED) displays. Prerequisites for patterning techniques include cost-efficiency, scalability to large area substrates (≥Gen 8), registration between multiple layers, and compatibility with state-of-the-art OLED technology. At present, state-of-the-art OLEDs are predominantly based on multilayered thin films of thermally evaporated small molecules and frequently contain phosphorescent emitters. This approach enables internal quantum efficiencies reaching unity [1] and operational lifetimes suitable for commercial display applications. [2,3,4,5,6] A common technique to fabricate multicolor pixelated OLED devices is shadow mask patterning. However, there are severe limitations

“…As can be seen in Figure 4 and Table 1, the mobility of the transistors that have been exposed to the stripper solution drop to almost half the value seen for the unwashed sample. While the stripper solution, a hydrofluoroether solvent base [5], is nominally orthogonal to the FlexOS TM OSC layer, there is likely a subtle interaction between the two materials which causes a degradation of the performance of the transistor ( Figure 5). …”

Organic light-emitting diodes (OLEDs) have become a promising candidate for lighting and display applications. High efficiency OLEDs require a multilayer device architecture to provide exciton confinement and balance charge transport. Conventional OLEDs are made by vacuum process, and the manufacturing cost can be reduced by solution processing. However, unlike vacuum-deposited OLEDs, solution-processed multilayer OLEDs are more challenging to make. The key for multilayer solution processing is to have the layer structure which can withstand solvents used in subsequent processing. We review the materials' strategies to make multilayer solution-processed OLEDs. Specifically, we will discuss the use of cross-linkable organic materials, metal oxides, and orthogonal solvent systems to deposit various functional layers in an OLED.
