White LEDs that can be printed and manufactured directly on paper have been developed by researcher Gul Amin from Linköping University.
With the development of this new technology, applications as diverse as luminous curtains, bright wallpaper that functions as lighting, self-lit books, etc., are possible.
Gul Amin, in his doctoral thesis at the Physical Electronics and Nanotechnology group, Campus Norrköping, demonstrated how it's possible for white LEDs to be grown directly on paper. And also, as an example, how to print them on wallpaper - the method for this is currently patent pending.
The LEDs, which are made from zinc oxide and a conducting polymer, can be manufactured directly on paper. The active components of the technology "are nanorods of zinc oxide on a thin layer of polydiethylflourene (PFO), a conducting polymer. But the paper has first been coated with a thin, water-repellent, protective and levelling layer of cyclotene, a resin."

Free webinars for LED lighting controller design
A series of free webinars co-hosted by MSC Gleichmann UK and Renesas Electronics are intended to provide engineering insight in use of digital control techniques in LED-based lighting products.
The online sessions will demonstrate how microcontroller-based techniques can be used to reduce system cost, increase energy efficiency and make used of various forms of connectivity.
Aimed at experienced designers and MCU novices alike, the webinars will provide specific examples of how to implement basic and advanced functions such as constant-current LED control, power factor correction (PFC), colour mixing, flashing and dimming sequencing, and sensor interfacing. Delegates will also learn the principles of DALI and DMX512 communications.
The first of these registration-only events will take place on July 5 at 11am. To register, visit https://www1.gotomeeting.com/register/690615569
Further events will take place on September 13 and November 22. To pre-register for these events, email lighting-uk@msc-ge.com
