OLED display technology initially gained momentum by pushing the boundaries of liquid crystal technology, thanks to its key advantages like no backlight, flexibility, and thinness. It has become increasingly popular in smartphones, large-screen TVs, VR, wearables, and other fields. However, this year, Micro LED has stolen the spotlight with its impressive rise in attention, showcasing capabilities that could transform OLED screens into mere transitional technology.
The reason Micro LED is seen as the next-generation display technology is rooted in its derivation from LED, yet it offers similar self-emissive benefits as OLED, combined with superior performance. Micro LED boasts lower power consumption, higher brightness, greater resolution, enhanced color saturation, faster response times, longer lifespan, and improved efficiency. Its power usage is approximately 10% of LCD and 50% of OLED, with brightness levels 30 times higher than OLED and a potential pixel density of up to 1500 PPI.
Several major players in the display industry have shown strong support for Micro LED through practical initiatives. Sony, the pioneer in Micro LED, focuses on developing large-screen solutions, whereas Apple is concentrating on smaller and mid-sized Micro LED applications for wearables. Samsung also made headlines earlier this year by acquiring PlayNitride, a leading Micro LED technology firm in Taiwan, to advance related display products.
Despite the excitement around Micro LED, its commercialization is still several years away. Apple has been forward-thinking in display tech and acquired LuxVue in 2014, gaining multiple patents along the way. They plan to begin small-scale production of Micro LED products by the end of this year, likely appearing on the new Apple Watch in 2018 and potentially on iPhones by 2020.
Clearly, Apple's enthusiasm for Micro LED isn't just about reducing reliance on Samsung OLED screens but also reflects the inherent advantages of Micro LED over OLED. Samsung, despite its dominant position in the OLED market, remains vigilant about future possibilities. International giants aren't alone in their pursuits—Taiwanese and mainland panel manufacturers are aggressively securing patents and investing in Micro LED research. Taiwanese firms lead the pack with numerous patents, R&D centers, and factories, and many of the companies acquired by global leaders like Apple and Samsung are based in Taiwan.
According to Taiwanese media and industry experts, Micro LED might see initial adoption in smart wearables, VR, or AR within 1 to 2 years, but larger displays may take 3 to 5 years to emerge. Once Micro LED overcomes technical challenges and achieves full-scale commercial production, it could mark the moment when OLED screens are relegated to a transitional role in the display world.
