IHS DisplaySearch says that while the global smartphone display market is contracting, AMOLED shipments are growing. The main reason for that is Samsung Electronics' use of AMOLED displays in low-cost phones, and the adoption of AMOLEDs by several Chinese phone makers.
DisplaySearch estimates that AMOLED sales reached $2.4 billion in Q2 2015, up from $2.3 billion in Q1, $1.7 billion in Q4 2014 and $1.5 billion in Q3 2014.
