UDC (Universal Display) that is dominating the global OLED emitting materials market, recorded 11% reduced OLED emitting materials revenue in 2015 compared to 2014. Despite the decreased revenue, it maintained its top place in the market.

According to 2016 OLED Emitting Material Annual Report, published by UBI Research, UDC recorded approximately $ 113 million in 2015 OLED emitting materials revenue. In 2014, this company’s OLED emitting materials revenue recorded $ 127 million and led the global market, and maintained its position in 2015.

In particular, this company is a dominating presence in dopant materials sector. In 2015, UDC occupied 82% of the dopant materials sector, and the rest of the companies share the remaining 18%. Based on the phosphorescent patents, it is supplying phosphorescent red and green dopant to Samsung Display and LG Display.

Following UDC’s top place in 2015 global OLED emitting materials market in terms of revenue, Idemitsu Kosan ranked 2nd, and this was followed by Novaled, Dow Chem., and Samsung SDI. In 2013, Dow Chem. was at the top of the market, but since 2014 UDC overtook the leadership. In 2016, LG Display’s OLED TV mass production line operation rate, materials structure of Galaxy Note series to be mass produced in H2, and other factors are expected to affect the OLED emitting materials market.

UDC is scheduled to announce 2016 Q1 performance on 5 May (local time).

In the midst of UDC`s domination of 2015 global materials market, with Japanese Idemitsu Kosan`s rapid growth and slump of emitting materials companied, there has been changes to the enviroment.

According to [2016 OLED Emitting Materials Annual Report] to be published by UBI Research in mid-April, the 2015 global emitting materials market recorded approximately a 17% growth compared to 2014

 

 

UDC’s revenue decreased from previous year, but remained at the top, the same as 2014. UDC was closely followed by Idemitsu Kosan despite its fourth place in 2014.

Such growth of Idemitsu Kosan is mainly due to its supply expansion in regards to Korean companies such as Samsung Display and LG Display. In 2015, Idemitsu Kosan began actively supplying Samsung Display with blue materials. Together with the increase in Idemitsu Kosan’s client LG Display’s OLED panel for TV mass production line’s operation rate, Idemitsu Kosan’s supply increased.

◆ Samsung Display to Determine Up and Down of Companies

On the other hand, some OLED emitting materials companies that ranked high until 2014 showed poor performance. Dow Chem., that reached the second place in 2014 after UDC in revenue, fell to the fourth place in 2015 due to a big sales decrease. The third and fifth companies in 2014, LG Chem and Duksan Neolux respectively, fell below fifth place in 2015 due to the same reason.

Dow Chem. and Duksan Neolux are analyzed have recorded sales decrease in comparison to 2014 due to the supply chain changes of Samsung Display. In the case of LG Chem, the sales fell as the Samsung Display’s supply volume decreased.

However, Samsung SDI recorded sales increase, and entered within the top 5 in 2015. This company’s performance improved as it supplied Samsung Display with green host.

The company that recorded greatest growth is a Germany company Novaled that Samsung SDI, then Cheil Industries, took over. This company recorded approximately 150% revenue increase compared to previous year, and reached the third place in 2015 following UDC and Idemitsu Kosan. With the increase in OLED panel for TV mass production line’s operation rate, Novaled’s revenue greatly increased.

UBI Research estimated that in 2016, LG Display’s OLED TV mass production line operation rate and Galaxy Note series’ material structure, to be mass produced in the second half, will greatly affect revenue of OLED emitting materials companies.

[IMID 2015] UDC Develops OLED Patterning Technology with Less Masks

/0 コメント/カテゴリ: , /作成者:

At present, FMM (Fine Metal Mask) is considered the main method for large area RGB OLED panel production. However, due to shadow effect, mask total pitch fluctuations, and mask slit tolerance issues, there is a yield limitation to this technology. This limitation increases as the resolution becomes higher; minimizing the number of FMM during the OLED panel production has been a key issue in RGB OLED production.

 

In SID 2014, through a paper titled “Novel Two Mask AMOLED Display Architecture”, UDC revealed a technology that can reduce the number of masks used in RGB-FMM method to 2 from previous 3.

As shown above, this technology coats yellow and blue subpixels using 1 mask each. Following this process, green and red color filters are applied above the subpixels. Pixels are formed as illustrated below.

UDC explained that this technology improves lifetime of the display overall and reduces energy consumption as blue voltage can be lowered. Additionally, tact time can be reduced through this technology, and increase the yield.

 

In IMID 2015, UDC presented research of the same title. However, the content of the presentation unveiled more developed research compared to 2014. First of all, in 2014, UDC announced that the panel’s lifetime could be improved by 2 times compared to the RGB method. In IMID 2015, UDC’s announcement changed the figure to 3.3 times increased lifetime.

 

UDC also revealed that the technology can be actualized through printing method, and has the advantage of being able to print 2 rows of pixels at once. UDC announced that this is most suitable when OVJP (Organic Vapor Jet Printing) applies the printing method.

 

A new technology called SPR (Sub-Pixel Rendering) was also announced by UDC in this paper. The 2014 SID paper included a method that did not uses SPR. As shown below in figure 1, 4 subpixels of RGY and B are used per pixel.

UDC announced that because APR technology allows the number of subpixels per pixel to be reduced to 3 or less, the number of data lines and TFT per pixel can also be reduced together.

 

UDC explained that this technology can be applied regardless of the display area or resolution, and will be able to be applied to different types of panels.

UDC presented a paper on a new technology that reduces power consumption and increases lifespan than the existing RGB-FMM method at SID 2014.

Under the title of “Novel Two Mask AMOLED Display Architecture,’ the paper describes the new technology to reduce to 2 mask from the existing RGB-FMM using 3 mask. In details, each pixel is divided into 2 regions; yellow and blue, and evaporation is performed with the yellow and blue masks. This technology is to form a pixel structure of YRGB by developing a color filter of red and green on the yellow region

UDC describes that the technology reduces the resolution by 33% compare to RGB FMM, but the increase of the blue region will increase the overall lifespan and decrease the power consumption of the display. It also announced that it could lower the production cost by reducing tact time and improving yield rate.

Like UDC, the industry develops various technologies to reduce the yield rate and cost of the AMOLED, and further continuous development of the AMOLED is expected.
