LED Phosphors And Quantum Dots: The Industry Is Rationalising


Yole forecasts that tier two and three companies without any elements of differentiation will exit the business

"Volume saturation, price pressure and a shifting intellectual property landscape are forcing the LED phosphor and quantum dot (QD) industry into a rationalisation phase," says Eric Virey, senior technology & market analyst, Yole Développement (Yole).

In this environment, Yole is expecting further rationalisation of the industry landscape with tier two and three companies exiting the business.

Most of those companies do not have any elements of differentiation, be it on performance or manufacturing cost that could allow them to survive in the mid and long term. For most phosphor suppliers, the name of the game is to keep decreasing costs as volume increase and revenue remain essentially flat, according to Yole's latest Phosphors & QDs report.

But despite increasing commoditisation, the LED phosphor & QDs industry still offers opportunities for innovative companies to strive, says Yole. While price ranges for established composition will narrow, a significant gap between low end and top performers will persist. This will enable some suppliers to keep capturing significant added value. The LED industry still has unmet needs in terms of phosphors. Companies able to develop and commercialise new narrow-band red and, to a lesser extend, green materials might still hit the jackpot"¦

Saturating volume and continuous price pressure creates a challenging environment for phosphor suppliers. Indeed, after five years of cut-throat competition that has driven prices to levels that nobody would have believed sustainable just a few years back, phosphor prices slowed their free fall in 2016.

After experiencing a proliferation of new entrants in China in the 2012-2015 period, the phosphor & QDs market has entered in a new phase: with increasing demand for quality, consistency and customisations, the weakest players are exiting the market. Surviving companies have sizeable R&D effort and long term expertise in researching, developing and manufacturing phosphors. Leading suppliers have also developed closer relationships with LED packaging companies, enabling a virtuous circle of co-development and feedback loops enabling further performance improvement.

The competition remains strong. Price, performance and ability to customise products for a specific need are strong element of differentiation.

The analysts from Yole say that a market can often be lost for a 1 percent difference in performance. Phosphors need to be optimised and customised for each product: a phosphor delivering top performance for one package at one customer might underperform in another package.The final performance of a phosphor in a LED package can vary based on parameters that are out of the control of the supplier: binder type, viscosity, mixing and dispensing method, procedures etc. To ensure optimum performance, close collaboration between the phosphor maker and the LED packager is required.

Regarding the current leading suppliers such as MCC, Intematix, Denka and other, Yole confirms their good market position. All of them remain on the top but strong companies are emerging in the Chinese market. While still focused on the domestic market, the consulting company is expecting some to become credible global players within the next three years. For example: Grirem, Yuji, Shield"¦

In parallel, Yole highlights the IP status of this industry. Key patents held by Nichia and Osram have started expiring in 2017 and will continue to do so in 2018. While both companies have since built on those patents and created broad families of intellectual property (IP), it will become much more difficult for them to prevent competitors from using garnet phosphors in their LED packages.
