Acerca deste livro eletrónico
Organic LEDs (OLEDs) in mobile displays have been in large-scale production for over a decade, and OLED-based televisions are rapidly gaining traction in the marketplace. OLEDs are on the verge of entering the solid-state lighting market in a big way. The OLED technology gives higher color purity and is more efficient than any of the competing technologies. When produced at scale, OLEDs are also economical. A key limitation in the development of OLEDs was the efficient conversion of all of the electrical energy put into the device into light. Until the late 1990s, the maximum efficiency of OLEDs was limited to 25% (photons/electrons), but this limitation was removed and OLEDs with 100% efficiency were reported in the early 2000s. This advance in OLED technology was driven by the author of this book. He and his collaborators developed electrophosphorescence, which is essential in reaching the 100% efficiency that is now commonplace in commercial devices.
Acerca do autor
Mark E. Thompson received his BS in chemistry in 1980 from the University of California, Berkeley, and his PhD in chemistry in 1985 from the California Institute of Technology. He was a postdoctoral fellow at Oxford University and is currently the Ray R. Irani Chair of Chemistry at the University of Southern California. His research involves the study of materials and devices for electroluminescence, photovoltaics and solar cells, chemical/biological sensing, and catalysis. Prof. Thompson is the author of approximately 400 papers in refereed professional journals and holds more than 250 patents primarily in the areas of optoelectronic applications, such as light-emitting devices and solar cells.
