Organic Light Emitting Diodes: Innovative Lighting and Display Solution

Abstract

OLEDs (Organic Light Emitting Diodes) are a breakthrough innovation in lighting and display technology for a wide array of reasons. OLEDs can be implemented in various applications from home lighting, to TV screens or GPSs. OLEDs have a 30% higher efficiency than inorganic Light Emitting Diodes (LEDs) [1]. In this review, we will delve into the pros and cons of OLEDs, as compared to other current lighting/display technologies [2]. OLEDs utilize various combinations of organic substrates to suit many specific lighting applications. A wide array of applications will be brought up and analyzed in this review. For most OLEDs, the anode is transparent, while the cathode is made of metal. The organic layer in the OLED generally has a thickness between 100 and 150 nm [3]. The specific substrates used in these applications, and their benefits will be thoroughly investigated. OLEDs are a new-age solution to hazardous forms of lighting such as CFLs (Compact Fluorescent Lamps), which contain the pollutant, Mercury (Hg). [4] More information on their environmentally friendliness and social benefits will be explored in this review as well.
