Digitimes hints that South Korean OLED producers bringing OLED materials in house
Taiwan based Digitimes indicated in an article that Samsung Display (pvt) and LG Display (LPL) are decreasing their reliance on outside sources for organic materials used to produce flexible OLED displays. While this is ultimately true, that South Korean firms would ideally like to have ultimate control over the materials used in the production of flexible (and other) OLEDs, the article did little to specify any changes that have not been mentioned previously, generally citing mergers and investments by both producers that would help them gain the necessary IP to bring production of flexible OLED materials to Samsung SDI (006400.KS) and LG Chem (051910.KS) respectively.
The article specified that both producers obtained polyamide varnish from Japanese supplier Ube Industries (4208.JP) and a number of other TFT backplane production materials from South Korean suppliers ENF Technology (102710.KS), Dongjin Semichem (005290.KS) and Dongwoo Fine-Chem (pvt), a division of Sumitomo (8053.JP), none of whom struck us as different than would have been expected. Further, deposition materials, a far more important component of the OLED production process, were specified coming from Idemitsu Kosan (5029.JP), Universal Display (OLED), Dow Chemical (DOW), and Merck (MRK), but hinted that the Samsung purchase of Novaled and an investment in Sun Fine Chem, a division of Hodogaya Chemical (4112.JP) were leading to the acquisition of IP that would allow these organics to be made internally, and finally that flexible substrates and cover glass were sourced from 3M (MMM) and Corning (GLW) respectively.
While there are a great number of materials and suppliers used in the OLED production process, this article did little to shed any light on current or potential changes that have been implemented by South Korean producers. Samsung purchased Germany based Novaled for $347m back in August 2013, a company known for its ‘PIN OLED’ material that is used to enhance the electron mobility of certain OLED stack layers. It doesn’t replace other stack components, but works with other stack materials to give better overall stack results, and an investment by Samsung in SFC (Sun Fine-Chem) a division of Hodogaya Chemical, goes back to 2011.
We believe that the only thing relating to OLED materials that has changed recently, other than the usual vying for a position in the OLED stack of these South Korean producers, is the change in backplane made by Samsung Display earlier this year. This change, to the M8 backplane did make some changes in OLED material suppliers, with red host material moving from Dow to Duksan Neolux (213420.KS) and green host moving from Samsung SDI to Nippon Steel (5401.JP), while other emitter and host materials suppliers remained the same. While on a long-term basis, OLED producers are always looking to reduce costs, using their leverage to pit one supplier against the other, that doesn’t always lead to using home country or in-house suppliers, as is seen in the change above where green host moved from an in-house South Korean supplier to a Japanese supplier, and both producers evaluate many materials from suppliers to find the right combination of performance and cost. If a local or in-house supplier can meet those needs, everyone is satisfied, if not, there is no hesitation on the part of Samsung Display and LG Display to use outside suppliers, and that has not changed over the last few years.
