Phone when Folded, Tablet when Opened… President of UBI Research ‘Flexible OLED Opens New Digital Convergence’

Combining smartphone and tablet PC, flexible OLED is expected to be a key player in opening the new digital convergence era.

During the Industrial Forum IMID 2016, held on 23 August in Jeju ICC in South Korea, the president of UBI Research Choong Hoon Yi gave a keynote speech and suggested the changes to the industry that flexible OLED will bring.

Yi discussed diverse applications for flexible OLED and emphasized that digital convergence where tablet PC is absorbed into smartphone will occur. He explained that flexible OLED will open the foldable phone era where the screen can be completely folded, and innovative product which will become a 5 inch smartphone when folded and a tablet PC when opened will be developed.

Yi explained that using the flexible OLED’s characteristics of thinness, lightness, flexibility, and spatial efficiency, it will be widely used. He estimated that not only will flexible OLED be used in automotive screen, lighting, flexible signage, and foldable game device, it will be utilized in diverse areas from wearable products such as smart helmet to smart fashion.

Referencing UBI Research’s analysis, Yi forecast that in 2020, 60% of the total smartphone will be OLED smartphone, and in 2021, 70% of OLED smartphone will be equipped with flexible OLED.

With diverse merits, OLED application is increasing to include notebook, tablet, monitor, etc. Accordingly, Samsung Display’s OLED panel is being actively expanding to this market.

HP recently began shipping Spectre 360, a notebook equipped with Samsung Display’s 13.3 inch OLED with resolution of 2560 x 1600. Previously, in CES 2016 (6-9 Jan) Samsung Electronics revealed Samsung Display’s 12 inch OLED equipped Galaxy Tab Pro S, and HP and Dell also presented Samsung Display’s 13 inch mark OLED equipped labtop.

In SID 2016 (22-27 May), Samsung Display presented 2560 x 1440 resolution 13.3 inch and 14 inch OLED for notebook and actively targeted the notebook market. Following this, a Korean press reported that Samsung Display will stop production of TN panel, low resolution LCD panel for notebook and monitor. That Samsung Display is actively targeting the notebook market is analyzed to be a strategy to create premium market advocating diverse advantages of OLED.

Due to superior contrast ratio, OLED’s picture quality is clearer in comparison to LCD, and easy to create premium market as the weight can be lighter than LCD. Burn in effect, considered one of OLED’s drawbacks, is also known to have been much improved.

As the price of OLED is higher than LCD at present, specialist market, such as medical, should be targeted first. However, when the price competitiveness improves in future, popularization of OLED is anticipated. Accordingly, Samsung Display is actively taking action in notebook and tablet OLED market expansion. UBI Research reported that 2016 Q1 OLED panel shipment for tablet increased by more than 10 times compared to the same period in 2015.

According to UBI Research’s 2016 OLED Display Annual Report, the 11 inch – 13 inch, notebook and monitor use, OLED panel shipment is expected to record 100,000 units this year, and this is expected to increase by 10 times in 2020.
