The approach prevents light from being trapped in the light-emitting part of an OLED, enabling OLEDs to maintain brightness while using less power
Keely Portway looks at how optical software is being used to design light sources
3D technology is just one of the innovations emerging in the large display market, as Andy Extance assesses the prospects for LCD, OLED and microLEDs in the fight for a share of this competitive space
In this whitepaper PhOLED are investigated using an FS5 Spectrofluorometer with electroluminescence accessory. Spectrum and chromaticity coordinates of the PhOLED emission are measured and triplet lifetime determined using time-resolved spectroscopy.
Apple supplier Ams has developed a light and infrared proximity sensor that can sit behind a smartphone’s screen, reducing the area required to house such sensors to allow for a larger screen size
Fraunhofer FEP scientists have developed a new micropatterning approach for OLEDs on silicon substrates, which could potentially eliminate the use of colour filters and shadow masks and allow full-colour displays to be developed by means of a new process
Televisions are receiving a major overhaul, Matthew Dale finds, with quantum dot and OLED technologies competing to give displays a wider gamut of colours
Advances in optical metrology equipment are helping the semiconductor industry increase productivity and reduce downtime, finds Keely Portway
Andy Extance finds the pains and gains of laser light’s different behaviour in water for oceanographers using lidar
Carlos Lee, Epic’s director general, talks to Martina Mueller, CEO of 3D AG, a Swiss company specialising in micro and nanotechnology and holographic structures
David Giltner, founder of TurningScience, discusses whether these two seemingly different career paths can successfully overlap
Matthew Dale reports on the association’s yearly event, where the importance of diversity, photonics funding and investment were to the fore
Géraldine Andrieux, at Blumorpho, shares her top tips on getting investors’ attention as a startup
Scientists have developed a lensless, infrared spectral-imaging system for medical diagnostics
