South Korea's LG Display swung to an operating profit of 250.6 billion won ($189.3 million) in the third quarter, reversing a 107.7 billion won loss in the previous quarter, driven by stronger seasonal demand for OLED panels. However, earnings fell 42 percent from a year earlier, as a weaker dollar and rising component costs weighed on profitability. Revenue rose 12 percent from the second quarter to 6.28 trillion won.
