Samsung have recently added one 3.5G (730x460mm) AMOLED vapor-deposition machine to its 3rd production line in Cheon-an. The new monthly capability is now 24K panels (when all 3 lines are combined). They also plan to buy two new 3.5G machines (which will double the production rate).
In related news, Samsung Electronics say they will sell around 10 million phones this year with AMOLEDs (that's around 5% of the total phones they plan to ship in 2009). SMD says that other mobile-phone makers are also increasing their orders for AMOLED panels.
