Korean media reports that due to a fire at Samsung's A3 OLED production fab in Asan, the company had to shut down the production at some of the lines. Luckily, there were no casualties.
Samsung Displays says that this won't effect the supply of OLED panels, but the extent of the damage is not yet determined.
The A3 line produces flexible AMOLED displays and has a monthly capacity of 130,000 substrates. It is not clear whether all lines were disrupted or only some of the lines.
