Taiwan's DigiTimes is reporting this morning that Apple will use a four inch display in their upcoming iPhone 5 so as to compete with Google's android phones. The displays are now in a production testing phase, according to DigiTimes. In this same report, DigiTimes adds that OLED is another important development on the horizon. In July 2010, DigiTimes reported that rumors were swirling around the iPad adopting OLED in 2011. Finally, in a second report this morning, DigiTimes is reporting that Apple is shifting their "enhanced A4" processor for the iPad 2 and possible A5 based iPhone orders away from Samsung and outsourcing them to TSMC (Taiwan Semiconductor Manufacturing Company). DigiTimes speculates Samsung's aggressive moves against Apple's products may have prompted the shift.
