AUO Optronics will demonstrate several new MicroLED display prototypes at Touch Taiwan 2021. AUO now brands its microLED displays as ALED displays.
The first display, which you see above, is a 1.39-inch 472x472 (338 PPI) full-circle microLED display. AUO says that this is the highest-density MicroLED display ever developed. AUO did not disclose more about this display (which was developed together with PlayNitride) but the company says that it offers ultra-wide viewing angles and high brightness.
AUO also says it will "showcase micro LED display developed with global consumer electronics giants". This is seemingly a modular (tiled) microLED display based on an LTPS backplane.
