Samsung is aiming to improve their AMOLEDs in the near future. They claim they will double the efficiency (from 20cd/A to 40cd/A), the lifetime (from 50,000 to 100,000 hours) and the power consumption (from 62W to less than 30W). Samsung will use advanced color pattern methods to overcome the current FMM method large-size limitation. They will also move from glass encapsulation to thin-film, and apply Oxide substrate. They will also use only triplet OLED emitters instead of using both singlets and triplets.
Samsung has recently began to construct their new 5.5-Gen AMOLED plant, which will start production in July 2011. Samsung plans to invest $2.2 billion on that plant that will have 3 production lines (1300X1500mm). Having a larger wafer size results in better efficiencies for both small and large panels (such as 30" or 40" OLED TV panels). Samsung did not say whether the new methods will apply in the new plant only, or also in the current one.
It's good to see that Samsung is able to improve their AMOLEDs so drastically. OLEDs are still in very early stages, and we're likely to keep seeing big improvements in the coming years.
