SEOUL, Oct 27 (Reuters) - South Korea's LG Display Co Ltd posted on Wednesday a more than three-fold jump in third quarter operating profit from a year earlier, as pandemic-driven demand for television sets boosted prices for large-screen flat-screen panels.

The Apple Inc supplier posted an operating profit of 529 billion won ($449.36 million) for the July-September period, versus 164 billion won a year earlier.

It missed an average analyst forecast of 600 billion won compiled by Refinitiv SmartEstimate. ($1 = 1,177.2300 won) (Reporting by Heekyong Yang and Joyce Lee; Editing by Himani Sarkar)
