IHS DisplayBank say that AMOLED shipments grew 8% in the second quarter of 2012, after decreasing slightly (2.5%) in the first quarter. Total shipments in Q2 were a little over 35 million units. Average size and price increased by about 1% of Q1.
DisplayBank says that Samsung is still the main supplier with over 90% of shipments, and this is not really news. They say that LG Display faced low demand from their main customers (LGE and Nokia).
