iSupply says that AMOLED display shipments were up 14% in the first quarter of 2012 compared to Q4 2011 - even though this is a traditionally slow season. Shipments are up 80% compared to Q1 2011. iSupply sees AMOLEDs gaining further traction as they are being adopted by tablets.
AMOLED average panel price actually increased 0.9% to $54 - but this is due to the introduction of higher specification displays. AMOLED still carry a price premium of 15 to 25 percent compared to LTPS LCDs. A 4.3" qHD (960x54) Super-AMOLED costs $51. A comparable LCD costs $42.
iSupply says that AMOLED tablet displays cost about $100. The only AMOLED tablet display is Samsung's 7.7" Super AMOLED Plus display (used in Samsung's own Galaxy Tab 7.7 and in Toshiba's upcoming Excite 7.7), so $100 is probably the price of that panel.
