Importance of Eco-Friendly OLED Lighting

Abstract

The importance of artificial light has long been recognized as it extends the day. Copious corporations and academic institutions are investing cosmic treasures in tracking down the advanced artificial lighting applications with a vision towards energy efficient and eco-friendly solid state lighting. In this regard, organic light-emitting diodes (OLEDs) are going to change the human lifestyle, by offering a promising avenue to develop future energy saving solid-state lighting sources because of their intrinsic characteristics such as low driving voltage, high resolution, high brightness, large viewing angle, large color gamut, high contrast, less weight and size, efficiency etc., there by dictating their ability to reach the pinnacle in the field of flat panel displays and solid state lighting sources. With the goal towards future application, many design strategies like synthesis of novel materials, well judged anatomy of device configuration, development of refined and low cost fabrication techniques have been put forward to achieve high efficiency, good color stability and quality lighting. Practical applications, which enrich the ideas of the specialists in this field to develop new routes for future research development of OLEDs are enumerated and illustrated by specific examples. This chapter also integrates the novel approaches for energy efficient and eco-friendly solid state lighting as well as the limitations and global haphazards of currently used lighting systems. The current state of the art, ongoing challenges and future perspectives of this research frontier to reduce the driving voltage, minimization of degradation issues, enhance their life time are illustrated. Review on the status and future outlook of these OLEDs strongly reveals their emergence in the next few years.

Expressed Willingness and Awareness of Students towards Climate Change in Lahore, Pakistan

“…Energy-efficient fluorescent bulbs not only bring down your energy bills but are also beneficial for the environment. They consume fewer energy units of light emitted and so fewer greenhouse gases are emitted from the power plants as less fuel is burnt (Thejokalyani et al, 2014). It will be good if the families of the respondents are also willing to replace all the bulbs of their houses with energy-efficient fluorescent bulbs just like them.…”

Simple-Structured OLEDs Incorporating Undoped Phosphorescent Emitters Within Non-Exciplex Forming Interfaces: Towards Ultraslow Efficiency Roll-Off and Low Driving Voltage for Indoor R/G/B Illumination

“…Aggregation-induced emission (AIE), color tunable, efficient undoped OLEDs and good mechanochromic properties were confirmed ( Ruan et al, 2016 ). On the other hand, a deeper understanding of device physics, photophysics (e.g., exciplex ( Park et al, 2013 ; Seino et al, 2014 ; Shin et al, 2014 ), electroplax ( Wang et al, 2004 ; Yang et al, 2009 ; Luo et al, 2017 ), excimer ( Chen et al, 2016 ), or TADF ( Lin et al, 2018 ) property), and novel device structure with efficient exciton harvesting ( Schwartz et al, 2007 ; Wang et al, 2009 ; Cui et al, 2016 ) also play a key role in the development of OLEDs with UEML. The Cao group fabricated a novel white OLED with a doping-free process ( Liu et al, 2014b ; Liu et al, 2016b ).…”

“…Over the last few decades, OLEDs have achieved far fetched academic and industrial attention due to their important applications in high-quality full-color displays and solidstate lighting [1][2]. OLEDs have exceptional features such as high color purity, high luminance, a wide viewing angle, high contrast, high response speed, low power consumption, a simple fabrication process, ultra-thin structure, lightweight, flexibility, and low cost [3]. OLED devices can be fabricated via dry or wet process.…”
