Japanese Nobel Laureate Shuji Nakamura, known for his invention of blue LED manufacturing technology and several subsequent LED innovations, disclose the history of blue LED and shared with the public his insights concerning the future of the LED industry on 8th Feb. at Academia Sinica. As general lighting has lately come to the stage of maturity, which hindered the LED industry, LED manufacturers are now seeking potential markets where they could recuperate and thrive. In his speech, Nakamura 'illuminated the industry’ by unveiling three future LED applications: Micro-LED, laser lighting, and the Li-fi technology.

Micro-LED became a hot keyword in 2016, despite being years away from commercialization. Most in the industry agree this exciting next generation display technology will not be realized for another 3-5 years, HSBC projects the earliest date of commercialization will be around 2019 earliest.

Color conversion is a challenge for micro-LEDs where pixels can approach sizes smaller than 5 microns, particularly in micro-displayapplications for mobile devices where overall size, as well as efficiency are all important. Traditional phosphors and even quantum dots (QDs) are not applicable to the micron sized LEDs, principally because of the thickness of material needed.

Founded three years ago, Idaho-based Rohinni is eyeing different segments in the micro-LED application sector with a LED die based manufacturing process: the first industries they have targeted will be keyboard backlight, logo and the automotive lighting sector.

The slowdown in LED backlight market including smartphone displays continued to trend on into 2016 that even top player in the industry Nichia is looking beyond this particular market sector in its 2017 roadmap.

Apple’s developments in the market are a hot topic in the technology industry, market rumors that next generation iPhones would be using OLED displays ushered in a large wave of investments in the sector in China. OLED, which was a niche market product, became a hot commodity this year because of Apple’s interest in adapting the technology in next-generation iPhones.

Global LED manufacturers are starting to develop micro-LED but there are still many bottlenecks to overcome before it can enter mass production, and most industry experts agree it might take another five to 10 years before it can be commercialized.

Oculus, the virtual reality headgear developer owned by Facebook, has newly acquired an Irish micro-LED company InfiniLED, reported Venture Beat.

X-Celeprint, a XTRION owned company, is working with potential partners to adopt its elastomer stamp micro-assembly technology for commercialization, the company CTO Christopher Bower told LEDinside during LEDforum 2016, which took place in late September in Taiwan.

LEDinside, a division of the global market research firm TrendForce, held LEDforum 2016 at National Taiwan University Hospital (NTUH) International Convention Center on September 30. This conference, which focused on micro-LED as the next-generation display technology, featured presentations by industry and research heavyweights including Epistar, Trillion Science, hTC, PlayNitrides, OSRAM Opto, Macroblock, Industrial Technology Research Institute (ITRI), X-Celeprint and CEA-Leti.

Micro-LED is regarded as a promising next-generation display technology that is being quietly developed by major brand companies in various industries. According to LEDinside, a division of TrendForce, displays for wearable devices and large indoor public displays are two applications that offer micro-LED the quickest paths to commercialization.   

Just as LED manufacturers are struggling in face of the declining profit in the lighting sector and the contraction of the backlight market, OLED emerges as the latest threat to their survival. Elevated by its potential to become one of Apple’s core technologies, OLED has expanded rapidly into various display and niche applications. While the LED industry expects even more challenging times ahead, new opportunities also appear on the horizon. Micro LED, which has been incorporated into Apple and Sony’s product roadmaps, are poised to become a commercially viable display technology that can be mass produced for everyday applications.
