In April Korean press ran stories that Samsung has started construction of its A4 flexible OLED fab, which was later denied by Samsung. The Korea Economic Daily now states that Samsung is now ready to start construction, which was confirmed apparently by the Asan city government which is expected to approve the plans by July.
Samsung's A4 line will be, according to the report, another 6-Gen fab, similar to its A3 fab which is already in mass production. The A4 will have a monthly capacity of 60,000 substrates (other reports suggest that full capacity will be 135,000 substrates - similar to the A3 line). The A4 is expected to start mass producing panels in 2019. Total cost for this fab is estimated at $7 billion to $11.5 billion.
