AUO's president Paul Peng says that large-size OLED panel will not challenge LCD panels in the next few years due to low yields and high costs. In fact, he says that OLED TVs may end up like SED and FED TVs which never really entered the market.
As far as we know AUO is still struggling with small-size OLED panel production, but Peng claims that the company already produces those panels. In the past few months AUO demonstrated several small OLED panels - a 4.4" 1900x600 (413 PPI) panel, a 5" Full-HD (443 PPI) AMOLED panel and their newest 5" HD720 AMOLED panels which seem to be closer to production. If Peng is right and the company indeed started production this will be great news. Earlier reports suggested that HTC and Sony are both waiting to integrate AUO's AMOLEDs in the mobile devices.
Peng also remarked that AUO has the ability to produce large OLED TV panels. In May 2013, AUO unveiled a 65" Oxide-TFT direct-emission OLED panel. This was the largest OLED panel ever made for a few months until LG unveiled their 77" curved UHD OLED. AUO's 65" panel features Full-HD resolution and was produced at the company's Gen-6 fab which uses the world's largest Fine Metal Mask (FMM). This same fab also produced 56" AMOLED substrates used by Sony and Panasonic in their OLED TV prototypes unveiled at CES 2013.
