Royal Philips Electronics is one of the world's biggest electronics companies and Europe's largest.
Philips used to develop both OLED displays and OLED lighting. The company withdrew from the display industry in 2007 (it's Philips brand TVs are now developed and marketed by TP Vision) and in 2015 Philips sold its OLED lighting business unit to US-based OLEDWorks (which will continue to offer OLED panels under the Lumiblade brand).
Here's our 2009 review of Philips' OLED lighting panels, and here's a second review we did in the same year of another panel. In December 2010 we posted an interview with Philip's OLED unit business chief.
In 2016 Philips introduced its first OLED TV, the 55" 901F, which is now shipping in Europe.
