An oversupply of LCD panels from China has pushed the world’s largest supplier, LG Display, into a rare Q3 loss.

The South Korean company announced a 437 billion won (A$545 million) operating loss for the July-September period after sales shrank 4.6 percent from a year earlier.

This is LG Display’s first Q3 operating loss in eight years, with the three months through September usually seen as a bright spot for the manufacturer.

This is because the period coincides with increased panel supplies to Apple ahead of the release of new iPhones.
