Earlier this year, reports suggested that Samsung Display is considering a new flexible OLED plant, its largest OLED fab yet. The so called A5 fab was reportedly to have a monthly capacity of between 180,000 to 270,000 6-Gen substrates (it's current largest OLED fab, the A3, will have a monthly capacity of 135,000 substrates when the current expansion phase ends later this year).
A new report from Business Korea suggests that Samsung has confirmed the new fab, and is now debating whether the first phase in the A5 fab will have a capacity of 30,000 or 60,000 monthly substrates. Samsung will start constructing the fab in December 2017. The new fab building alone is estimated at $1.75 billion.
