New electrode could make OLEDs 20% brighter

The approach prevents light from being trapped in the light-emitting part of an OLED, enabling OLEDs to maintain brightness while using less power

Model behaviour

Keely Portway looks at how optical software is being used to design light sources

Resolution evolution

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

Electroluminescence and Photoluminescence Spectroscopy of a Phosphorescent Organic Light Emitting Diode (PhOLED)

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.

A new era of colour

Televisions are receiving a major overhaul, Matthew Dale finds, with quantum dot and OLED technologies competing to give displays a wider gamut of colours
