Touch Taiwan 2021 Focuses on progress in Mini and Micro LEDs
Touch Taiwan 2021 showcased LED chips used in backlighting, industrial and physiological sensing and fine-pitch RGB MiniLED displays at the tradeshow from Epistar, under EnnoStar. Lextar, also under EnnoStar, is exhibiting a 147-inch RGB fine-pitch MiniLED display with a pitch of 0.46mm, 12.3- to 65-inch COB (chip on board) and DOB (driver on board) MiniLED-backlit LCD panels for automotive and marine displays, notebooks, desktop monitors and TVs. Lextar also showcased micro LED displays developed in collaboration with US-based X Display, with such displays featuring over 70% transparency and contrast of 1,000,000:1. EnnoStar has a capex budget of NT$6.5-7.5 billion (US$229-264 million) for Epistar and Lextar's capacity expansions and R&D in 2021. Epistar currently has annual MiniLED chip production capacity equivalent to one million 4-inch wafers.
AUO Optronics demonstrated several new MicroLED display prototypes at Touch Taiwan 2021. AUO now brands its MicroLED displays as ALED displays.

Figure 1: AUO’s 1.39” Micro LED Display
The first display is a 1.39-inch full-circle MicroLED display that offers a 338 PPI. 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 will also show its 12.1-inch 169PPI MicroLED display it first demonstrated in SID 2020, and the 9.4-inch 228 PIP flexible MicroLED prototype it developed together with PlayNitride. 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.
PlayNitride showcased an 89-inch 32:9 aspect ratio 5K curve MicroLED display based on its own PixeLED Matrix technology. The display consists of 168 MicroLED panels in mosaic and features a curvature radius of 2,500mm and brightness of 2,000nits. PlayNitride is also exhibiting SenMirror, a PixeLED Matrix-based MicroLED display integrated with gesture sensors and a mirror that can be used as an interactive display and a mirror; a 1.39-inch circle-shaped MicroLED display with 338PPI, developed jointly with AUO, and a 0.39-inch MicroLED micro-display for AR/MR devices.
