Foxconn, which became a focus of global attention with the Sharp takeover, bought Nokia ’s mobile phone business.

It is reported that FIH Mobile Ltd, a subsidiary of Foxconn, bought Nokia’s feature phone business from Microsoft for USD 350 million. Accordingly, Foxconn now controls Nokia feature phone’s manufacturing, sales, and distribution. Foxconn also signed strategic partnership with HMD global that oversees product development and sales. HMD global is expected to invest USD 500 million for the development of Android-based smartphone, tablet, and feature phone for the next 5 years.

Foxconn took over Sharp in March, earlier this year. With this takeover, Foxconn is estimated to acquire LCD mass production line and also gradually be equipped with OLED mass production line for mobile device and TV. DigiTimes research estimates that Foxconn will mass produce OLED panel for smartphone from 2018 and begin OLED panel mass production for TV from 2021.

Some sections of securities industry have suggested that Foxconn’s takeover of Sharp allows for vertical integration of Sharp panels, and business expansion to include set such as smartphone and TV will be possible.

That Foxconn purchased Nokia’s mobile phone business after strengthening display mass production area reinforces this idea. It could be understood as a resolve to renew itself as a set company with their own brand surpassing their main business OEM.

Some are anticipating Nokia’s return as the mobile phone leader of the past with the Foxconn’s purchase of Nokia’s mobile phone business. However, the business still struggled even after Microsoft’s takeover move in 2014 worth EUR 5,400 million. As such, many believe that it will not be easy for Nokia to reclaim their former success.

OLED market is heating up again. Rigid OLED market growth was temporarily stalled but with Samsung Electronics and LG Electronics’ new flexible (plastic) OLED products, Galaxy S6 Edge and G Flex 2 respectively, the smart phone market’s temperature is rising. In order to maintain the storm that iPhone brought, Apple is preparing to release smart watch equipped with LG Display’s plastic OLED. Additionally, LG Elec. is targeting the premium TV market with their 55 inch and 65 inch UHD OLED TV.

OLED panel leading company Samsung Display decided on Gen 6 line’s additional investment for flexible OLED production expansion. LG Display also decided on supplemental extension of Gen 4 line in Paju responding to the shortage of plastic OLED supply. Furthermore, JDI is joining in and expected to begin Gen 6 flexible OLED line establishment soon.

Recently announced Samsung Display’s decision to invest in large OLED line is the most encouraging news. Frontline leader in OLED display, Samsung Display mass produced 55 inch OLED panel using RGB OLED and LTPS TFT technology. However, halting the production, Samsung Display explored for technology with better business value and recently selected to produce large OLED panel using WRGB OLED technology.

OLED panel production technology can be largely separated into 3 parts: TFT, OLED, and encapsulation. Large OLED panel production technology is very difficult to obtain yield compared to small panel. Therefore, while the above 3 technologies are important in producing good panel, technology that can acquire good yield for mass production can guarantee business value. Particularly, as encapsulation is the last process, the final yield depends on the encapsulation method.

In that case, what encapsulation technology is most suitable for large area OLED panel production? As OLEDNET article published on January 12 mentions, from the technology trend perspective the answer is hybrid encapsulation technology. This technology is completed with device’s passivation film, moisture proof top plate that can cover the top, and organic material that adhere the top and passivation film. From the design trend perspective, the technology must be able to bend. Recently, the TV market is moving toward curved design, and to respond to rollable display as well the top plate has to be metal rather than glass. (Reference, 2015 OLED Encapsulation Report, UBI Research)

Hybrid encapsulation technology can be further divided into film method and dam & fill method depending on the adhesive structure between top plate and passivation film. Film method is being applied to mass production by LG Display, and dam & fill method was developed led by Sony. This method dispenses adhesive polymer liquid after organic dam installation on the panel border. This can only be used when the top plate is glass. LG Display completes the process by sealing the metal plate laminated with adhesive film to the device. A best suited technology for curved TV and rollable TV production.

The OLED panel for TV production technology decided by Samsung Display was initially known to select WRGB OLED structure similar to LG Display, but TFT and encapsulation technology have not yet been revealed. However, TFT technology is highly likely to be oxide TFT. (Reference February 27 OLEDNET article) LTPS TFT has high investment cost compared to oxide TFT and has low business value at similar performance.

What is left is encapsulation technology. For this technology also a method already commercialized by LG Display, film lamination method, is most suitable since metal plate is favorable for curved design. Metal plates is strong against external shocks and favorable for heat sink. Glass has lower heat conductivity compared to metal and requires additional protection against heat; this means that production cost can only increase. Considering design, protection against external shocks, and reduced heat sink cost, LG Display’s hybrid encapsulation technology that uses metal plate is the most ideal. Therefore, the direction that Samsung Display should also head toward is metal plate and film using method.

Although small OLED for mobile technology developed by Samsung Display became the norm, it is estimated that LG Display’s technology will become standard for large OLED panel production.

[Analyst Column] AMOLED equipped smartphone promotes enlargement of the display on mobile device

According to the “2015 OLED Display Annual Report” published by UBI Research, it was researched that the 5-inch AMOLED display is the main product for a smartphone.

The report shows almost no fluctuation in the number of AMOLED equipped smartphone manufacturers for the last three years from 2012 to 2014 – 13 (2012), 11 (2013) and 14 (2014) – but the major smartphone display size that these companies sold was set in-between 4-inch and 5-inch.

Among 31 AMOLED equipped products, there was only one 5-inch smartphone accounting for 3 percent in 2012, but it has increased to 21 percent with 5 products among 21 in 2013, and 19 products in total of 27 forming 70 percent in 2014.

Samsung Electronics strategized the two elements which are not available in iPhone as points of differentiation to compete with the biggest smartphone rival company Apple. The first plan is targeting the color gamut of LCD. The existing LCD can only reproduce approximately 80% of NTSC which is the broadcasting standard. Although it became possible to enjoy TV and movies through a smartphone with the development of communication technologies, there is a difficulty in reproducing the 500nit of TV quality on a smartphone with the brightness of 200nit. The limit in increasing the brightness of a smartphone is in that the power consumption needs to be minimized to use the smartphone for a long time with the battery. In view of that, Samsung Electronics chose the AMOLED panel as a key strategic part meeting the NTSC standard in low power consumption as an alternative for the LCD panel for the consumers to identify more precise colors. It is expected that the demand for AMOLED panel capable of accurately realizing colors of a product will increase further given the latest growth in shopping clothes with smartphones.

The second plan is in the display size. While iPhone focused on a 3-inch small sized smartphone for a better sense of grip to enhance portability, Samsung Electronics was more focused on “a product of better visibility” rather than “a product of better hand grip”. Obviously the early AMOLED panel has low resolution. Therefore, the bigger display was needed to realize high-resolution as it is hard to fix the opening ratio of shadow mask which is used in manufacturing the pixel for AMOLED panel.

Samsung Electronics succeeded in catching up with Apple, the inventer of smartphone, in terms of the color gamut and size of AMOLED display. Now Apple finally abandoned the matter of grip and expanded the display size to 5-inch.

Although Samsung Electronics was a latecomer compared to Apple in the smartphone market, the choice of AMOLED by Samsung Electronics made the Samsung Electronics of today and also prepared the base for the AMOLED to thrive. In addition, the Samsung Electronics’ strategy enabled the smartphone display in the world to develop into a 5-inch “device to see”.
