Apple’s much anticipated iWatch launch date might be postponed to 4Q14, as the company runs into AMOLED manufacturing issues, according to Chinese-language China Times report.

Korean electronics manufacturer LG Display is rumored to become one of Apple iWatch’s OLED suppliers, according to a report by the Korean Herald. The report noted Apple has a tendency of diversifying its supply chain, and Taiwan’s RiTDisplay is a strong OLED candidate. The OLED supply chain is likely to be led by RiTDisplay with LG Display as the secondary Apple OLED supplier.
