Han Sang-beom, CEO of LG Display, has spoken to the Wall Street Journal about the firm’s plans for OLED investment. LGD will ramp up its second OLED fab by the end of the year, which will produce up to 26,400 substrates per month. A third plant is also being considered. The company is trying to diversify its client base for small screens, away from being reliant on a single customer (Apple).
