Jennifer Colegrove, director of display technologies at DisplaySearch, is optimistic about AMOLED production capacity: ""I expect in the next three years for at least 20 new AMOLED production lines to open up... This is the future of the display technology on smartphones and you'll see a lot of companies investing money to enter".
We already know of a few production lines that are expected in the coming years: Samsung has begun working on their 5.5-Gen Plant (that'll have 3 lines, a $2.2 billion investment), LG is also investing heavily in new lines, TPO is expected to launch products soon, AUO will soon start building their AMOLED line and Visionox has a pilot line ready.
