Organic Light Emitting Diode (OLED) Technology and its Applications: Literature Review

 

Abstract

An Organic Light Emitting Diode (OLED) was one of the growing leading semiconductor device technologies. This technology has several advantages over other technology such as eco-friendly lighting sources with superior color quality, wide viewing angle, mercury-free manufacture, fascinating flexibility etc. In an OLED a conducting an emissive layer was sandwiched between two electrodes to emits light in response to an electrical current. A various device structure, materials as well as deposition techniques have been investigated to achieve the better and improved performance of OLED. In this review we summarized the device architectures, materials and advantage and disadvantages of Organic Light Emitting Diode (OLED) has been discussed.

Keywords: Organic light emitting diode; Display; Liquid crystal display and organic LED; Hole transport layer; Hole block layer; Electron transport layer
