Three competing lighting technologies
Market rumors that iPhone will be fully converting to OLED displays by 2018 propelled the OLED industry during first half of 2016. OLED has been coined the next generation display technology, and its market share has rose among smartphone displays. According to market research organizations estimations, China’s smartphone AMOLED panel market penetration rates will reach 30% by fourth quarter of 2016, much higher than the global average of 20%.
Yet, OLED have short lifetimes, and there are still many challenges to mass producing large OLED displays. However, injection of capital and more comprehensive technologies will allow it to replace certain LED applications. Especially, once lighting developments reach a certain stage, consumers are looking for more than just a simple luminaire, paying more attention to its aesthetics. OLED can help designers achieve diverse possibilities.
Micro-LEDs are currently the most anticipated LED technology for 2016, especially after price wars disrupted LED industry supplies. Once OLED panels are fully adopted in monitors, micro-LEDs will become an innov
ative technology. The emergence of micro-LED is viewed by the LED industry as a chance to overturn LCD market conditions.
Micro LED’s future potential still largely rests on Apple. Apple acquired LuxVue in 2014 to manufacture micro-LED displays, bounding the emerging display technology future developments to it. Based on latest news, Apple Watch will be using micro-LEDs in 2017, and there are even rumors the Cupertino-based company has started testing micro-LEDs.
Once it is confirmed that Apple will adapt micro-LEDs in its next generation devices, it will no doubt stimulate the market, and create new opportunities for the LED industry.
The types of lasers LEDinside addresses here are GaN based laser diodes combined with advanced phosphor powder technology to emit white light. Lasers are focused onto a tiny spot on the phosphor, which is converted into white light. The laser is able to emit a direct white light that is safe, accurate, and directional. Additionally, micro optical lenses and reflectors can optimize light control to achieve better lighting effects.
Compared to blue LEDs, lasers do not have lumen depreciation issue. Lasers are highly efficient light sources. Nobel Prize Laureate Shuji Nakamura projected lasers would eventually replace LED lighting, and mentioned numerous times during talks in 2016 that lasers would be the future for lighting. He even claimed lasers would replace LED lights within 10 years.
Two LED products market position readjusted
Filament LED bulbs market position rises
The year 2016 turned around LED filament bulbs market situation, despite initial misgivings from the industry it succeeded against all odds. Filament bulbs have attracted Philips, Osram, GE and other global manufacturers to invest in the technology, while Chinese companies including Yankong Lighting, Foshan Lighting, INESA, Oppel Lighting, Honglizhihui, MLS, Runlite and other LED manufacturers that have pitched in production expansions.
According to an industry source, LED filament bulb market had grown exponentially from second half of 2015 till first half of 2016. The products are very popular in international markets mainly in North America, Europe, South America and other regions. It has also became a highlighted product in the Asia’s LED lighting supply chain.
Small pitch LED displays centered in battlefield
Small pitch LED displays are a conceptual product that was first proposed in 2008, flourished and grew exponentially in 2014. After 2014, though its growth had slowed significantly and failed to deliver. The industry even questioned if small pitch LED displays stellar performance would never return again.
By first half of 2016, small pitch LED displays market volume increased, presenting a lot more business opportunities for LED display manufacturers, especially with VR and AR trends. As a basic hardware infrastructure, LED displays also entered a phase of explosive growth, where HD displays and seamlessly connected small pitch LED displays greatly improved VR products and user experiences.
In the face of this new blue ocean, VR and AR have been integrating small pitch LED displays, to develop new commercial applications through new business models and profitability patterns. A lot of LED display manufacturers are ready to try out the new technology, including listed company Leyard, Liantronics, and Absen Opto.
One new LED chip term
FEMC is a new term presented by Refond Opto in 2016, when it was showcasing its new product portfolio. It is a brand new terminology in the LED industry, and stems from flip-chip +EMC concept, which means placing a flip chip LED package onto an EMC. The EMC is a type of flip chip product.
The emergence of FEMC has also kicked-off many flip-chip concepts, where there are many different types of flip chip models, which is not restricted to Chip Scale Package (CSP) models. There are many different types of FEMC including FC and PCT package structures, although flip chip lead frames are not a revolutionary technology, whether it will spread in the industry requires longer observation period.
Despite all the challenges and issues in the LED industry, there has been many changes during first half of 2016. The LED industry may be declining but it has also presented many new opportunities, whether from a technology or market development stand point. The LED industry delivered good performance during first half of 2016, and will maintain strong growth in second half of the year.
