Organic Light Emitting Diodes: Materials; Fabrications and Applications

Anju Singh ^[2] | H. L. Vishwakarma ^[2]

Abstract: In this paper I have discussed many points like fabrication materials; methods and applications of OLEDs. OLEDs with its diverse properties like low cost; ease of fabrication; brightness; speed; wide viewing angle; low power consumption; and contrast; plays an important role in replacing Liquid Crystal Displays (LCDs) and other lighting devices. A number of materials have been generated and improved in order to satisfy the requirements of these applications. Optoelectronic devices using organic materials are becoming widely desirable for diverse reasons [1]- [4]. Organic devices have the potential for cost advantages over inorganic devices. The inherent properties of organic materials such as their flexibility make them well suited for particular applications such as fabrication on a flexible substrate. The materials differ from one another not only by their structure but also by the mechanism involved in the electroluminescence produced (fluorescence versus phosphorescence). Owing to the advantages of solid-state; self-emission; full colour capability and flexibility; OLEDs have been recognized as one of the most promising flat panel display technology and has stepped into commercialization.
