“…The operational theory is the same as for the CCFL and the electrodes can be both internal and external. It has better light uniformity when it is applied as the light source for LCD panels [3,[27][28][29].…”

“…White light emitting devices are currently in high demand because of the fast growing electronic display industry. Unlike old-type cathode ray tubes, liquid crystals do not emit light themselves, so they need a light source called a backlight unit in order to function as display devices [3,4]. Due to the enormously increasing demand for large and small displays, there are huge needs for better quality backlight units.…”

“…Although it has been more than 100 years since fluorescent lamps (FL) were initially utilized for lighting applications, the growth of information technology and the related display technologies has brought new demands for quality white lights and better lighting devices. At the time when thin film transistor (TFT) LCD display devices first became commercially available in the late 1980s, there were not many choices for backlights and compared to incandescent lamps, FLs were the better choice due to their better energy efficiencies and more suitable emission spectra [3,7].…”

This review provides a comprehensive account of energy efficient lighting devices, their working principles and the advancement of these materials as an underpinning to the development of technology. Particular attention has been given to solid state lighting devices and their applications since they have attracted the most interest and are the most promising. Solid state lighting devices including white light emitting diodes (LEDs), organic LEDs (OLEDs), quantum-dot LEDs (QLEDs) and carbon-dot LEDs (CLEDs) are promising energy efficient lighting sources for displays and general lighting. However there is no universal solution that will give better performance and efficiency for all types of applications. LEDs are replacing traditional lamps for both general lighting and display applications, whereas OLEDs are finding their own special applications in various areas. QLEDs and CLEDs have advantages such as high quantum yields, narrow emission spectra, tunable emission spectra and good stability over OLEDs, so applications for these devices are being extended to new types of lighting sources. There is a great deal of research on these materials and their processing technologies and the commercial viability of these technologies appears strong.
