Japan Display Inc. said Friday it will extend the closure of its plant in Ishikawa Prefecture due partly to Apple Inc.'s weak iPhone sales as it considers a plan to make new organic light-emitting diode displays there instead.

The struggling panel maker said in June it would close its Hakusan plant in Ishikawa Prefecture from July to September because of weak demand for displays from Apple and fierce competition with Chinese panel makers.

However, Japan Display said in a statement that it has started talks with China's Harvest Tech Investment Management Co. about a plan to produce next-generation OLED panels for smartphones at the closed plant.
