Organic light emitting diodes (OLEDs) are as an electronic device that emit light in response to electric current. Typically, the structure of OLEDs includes a transparent conductive indium tin oxide (ITO) as an anode, a hole transporting layer (HTL), an emissive layer (EML), an electron transporting (ETL), and a metallic cathode. OLEDs can be potentially produced by low cost solution process, which is suitable for large size flexible displays. In recent years, many efforts have been done to produce the OLEDS by solution processable materials that resulted a way to achieve printable roll-to-roll organic optoelectronic devices. In order to have fully solution process, the used materials should be compatible with each other and not to damage or mix with each other. Therefore, the materials in a layer should be soluble in orthogonal solvents or cross-linkable that not mixes with other layers. The first part of this article described the hole transporting, electron transporting and active layers (HTL, EML, ETL) that able to coat by solution processing technologies such as ink- jet printing and spin coating. In the second part, this article talks over the materials, which used as anode and cathode in OLEDs by solution processe.
