Apple has plans to invest in a Sharp Corp factory in order to secure a supply of LCD screens for iPhones and iPads, according to a new report. Citing sources familiar with the matter, Reuters reports that the move has spurred speculation that Apple may move to diversify its range of suppliers in light of its ongoing legal dispute with Samsung. “If the situation escalates into a state of war, this could mean a huge shift in orders,” said one of the sources. The report notes that Sharp has already secured a contract with Apple to supply “power-efficient” screens for the sixth-generation iPhone, due in 2012. According to the report, Japanese media have said Apple’s investment may be as large as $1.3 billion; Sharp officials could not be reached for comment.
