AUO presents 32-inch inkjet printed AMOLED panel and 5.6-inch rollable dual-sided AMOLED screen
LG’s monopoly on the large OLED panel market might be nearing its end as new producers are stepping in with technologies that could finally fix all of the OLED inherent downsides and eventually bring down the costs closer to LCD prices. Among the new producers we see Samsung with its QD-OLED tech combining quantum dot films with conventional OLEDs, and there is also AU Optronics from Taiwan promoting the inkjet printed large AMOLED panels. While Samsung is apparently experiencing some production problems with the QD-OLEDs, AUO seems to be progressing nicely on the inkjet printed AMOLEDs, as well as bringing some more improvements to the smaller rollable AMOLED screens designed for smartphones.
The latest advancements from AUO are presented in a recent video where the company’s Senior Associate VIce President Jennifer Lin highlights the importance of “eco-friendly” OLED panel manufacturing, claiming that the inkjet printing process adapted to AMOLEDs can use far fewer materials compared to LCD panel production and even conventional OLED panel production techniques. This aspect also leads to reduced production costs that can translate to up to 25% lower retail prices compared to same size LG OLED displays.
For now, AUO can only produce inkjet printed AMOLED screens of up to 32 inches in diagonal, but the technology is advancing fast and larger sizes are expected to be launched in a few years. The particular model presented in the video has a 4K resolution with 144 Hz refresh rate and is said to have increased brightness plus wider color gamut, which makes it ideal for medical and gaming applications.
AUO is also presenting the 5.6-inch rollable dual-sided AMOLED displays designed for smartphones. One of the uses for the dual-side technology enables gamers to enjoy multiplayer games on the same device. AUO managed to reduce the thickness of the superimposed displays by 50% to minimize the mechanical stress when rolling, while maintaining the same brightness. Additionally, it improved the durability of the dual-sided screens to withstand more than 100,000 rolls at 9 mm curvature.
