AU Optronics has been developing OLED ink-jet technologies for many years, according to reports, and has setup a 3.5-Gen pilot ink-jet OLED printing line. Today AUO announced that the company is going to showcase its first ink-jet printed OLED panel at Touch Taiwan 2019.
AUO will demonstrate a 17.3" 4K (225 PPI) OLED display that was produced using an ink-jet printing process. AUO says that the display features a 120Hz refresh rate, a wide color gamut and high brightness (that AUO did not yet specify). AUO will also showcase 5.6" foldable OLEDs that can be folded inwards or outwards for customized design according to client requirements. The display's folding radius is 4 mm and it can be folded over 200,000 times. AUO will also demonstrate a 12.1" LTPS Micro-LED prototype, which seems to be the same one shown in 2018.
