Displays and Lighting: OLED, e-paper, electroluminescent and beyond

A revolution is in the making. Electronics will never be the same as new applications are spawned. Invisible, origami, edible electronics, low cost materials and manufacturing will lead to the use of electronics in spaces traditionally bare of their functionality.

The research and growth of new technologies, along with new materials and processing methods, is resulting in the increasing penetration of innovative electronics and the emergence of new products in the competitive fields of displays and lighting. Eye-catching, animated billboards; large-area, thin, flexible displays with amazing colour contrasts; windows that are converted into surface lighting elements at night.

IDTechEx has been following this market closely and has compiled a new comprehensive report on the technologies that are promising to be a "visual feast", a challenge to the senses.

IDTechEx Associate Dr Bruce Kahn and Technology Analyst Dr Harry Zervos are offering insight in the markets for innovation in displays and lighting in the next decade. The report is divided into four main parts.
