Nokia was once the world's leading mobile phone company. They were late to the smartphone revolution, and the company's mobile phone arm was sold in 2013 to Microsoft.

Nokia's first OLED phone

Back in 2006, Nokia introduced the 6215i phone that was actually a re-branded clamshell Pantech PN-315 handset, for the Verizon network in the US. The phone had a 65K, 97x64 PMOLED subdisplay.

Nokia AMOLED phones

Nokia has released several AMOLED phones to the market. In the pre-smartphone days the company released models such as the N85 and the N86, the N8 and the E7, C6-01 and the C7. In most of their AMOLED phones, Nokia used their ClearBlack Display technology (CBD) - which adds a polarized filter to the AMOLED and is said to deliver better outdoor visibility.

When Nokia abandoned Symbian in favor of Microsoft's Windows Phone OS, they continued to use OLED displays in most of their phones. The most recent one is the Lumia 930, the flagship Windows Phone 8.1 smartphone for 2014. The 930 has a 5" Full-HD Super AMOLED ClearBlack display, a 2.2 Ghz quad core CPU, 20 MP PureView camera (with optical image stabilization), Qi wireless charging and NFC.
