Back in January it was reported that HTC decided to use AUO's 4.65" OLED panels in their upcoming code-named M7 flagship phone. Yet other reports suggested that AUO still faces production issues and HTC decided to use Sharp-made LCD panels instead. Today HTC unveiled the HTC One phone, and sadly it is indeed using an LCD (4.7" 1080p Super LCD 3, 468 PPI).
So it appears that AUO still hasn't started to mass produce AMOLED displays. Digitimes says that it's likely that they wouldn't be able to start real mass production until 2014, which is a real shame.
