The company chalked up a net profit of $9.8 million in the July-September period, shifting from a loss of 442.2 billion won a year earlier.
It also logged an operating profit of 164.4 billion won in the third quarter, swinging from an operating loss of 436.7 billion won a year ago. Sales rose 15.7 percent to 6.73 trillion won over the cited period.
This is the first time since the fourth quarter of 2018 that the company posted an operating profit.
LG Display attributed the turnaround to increased supply of displays for IT products and plastic OLED panels for mobile devices, reports Yonhap news agency.
Panels for IT products accounted for 43 percent of its revenue in the third quarter. TV panels accounted for 28 percent of its revenue, while mobile display products made up 29 percent of its sales.
LG Display said it plans to double the shipment of large-size OLED panels in the second half of the year compared to the first half as operation of its Guangzhou plant is in full swing.
The company aims to supply more than 7 million units of large-size OLED display panels next year.
To cope with rising demand for panels for IT products, driven by the work-from-home trend and remote learning, the company said it will convert more of its LCD TV panel production lines to IT display manufacturing lines.
LG Display said it expects the strong demand for IT panels to continue through the first half of 2021.
