[Finetech Japan 2015] Mobile Display up to 700 ppi. How about OLED?

At Finetech Japan 2015 (April 6-8), vice president of LG Display, Yoon Sooyoung, forecast the display resolution would evolve to 700ppi UHD for differentiation in technology. Japan Display’s CBO Yoshiyuki Tsukizaki also disclosed that a person can perceive up to 700ppi and estimated that mobile display resolution would therefore develop up to 700ppi.

 

Currently mobile display is being mass produced at QHD (approx. 500ppi), and UHD resolution is known to being actively developed for LCD. It is analyzed that UHD mobile OLED panel development will be a necessity in order to adapt to the trend toward high resolution. OLED is being mass produced in RGB pixel structure where FMM (fine metal mask) is applied. However, as FMM production technology is difficult, QHD AMOLED panel is being mass produced via pentile pixel structure rather than real RBG pixel structure. Therefore, technology for realization of mobile UHD resolution is expected to be a key issue in future.

 

For the mobile UHD AMOLED panel realization, securing shadow mask technology that allows for UHD resolution is important. In Finetech Japan 2015, V-Technology exhibited FHM (fine hybrid mask) technology that can produce 700ppi or higher resolution. V-Technology further revealed that “resolution of up to 738ppi can be produced using laser patterning technology after the formation of polyimide film on top of Ni mask”.

 

Additionally, another method is where white OLED + color filter is applied which uses color filter patterning technology. This is a comparatively easier method for producing high resolution, and JDI is aiming for mass production using WRGB structure. Chinese latecomers are also examining application of white OLED + color filter structure for high resolution AMOLED panel production.

 

The attention of the industry is now focused on how OLED will react and what solution will be generated facing LCD sector that is evolving toward UHD mobile display.

[FPD China 2015] Tianma, Reveals China’s First FHD OLED Panel’

[FPD China 2015]Tianma, FHD OLED panelA display company Tianma succeeded in developing China’s first OLED panel with FHD resolution. There are several companies that mass produces or is developing AMOLED panel for smart phones. Samsung Display and LG Display are in Korea, JDI in Japan, and AUO in Taiwan. In China, the companies include Tianma, Visionox, Truly, and EveryDisplay, as well as BOE. The 4 companies that are mass producing the AMOLED panel are Samsung Display, LG Display, AUO, and EverDisplay. Of these, only Samsung and LG are pass producing FHD AMOLED panel.

 

With LCD panel for mobile, products with resolution of FHD or higher are already being mass produced. However, due to the manufacturing process, it is difficult to produce OLED panel with FHD resolution or higher. As emitting materials are evaporated via fine metal mask (FMM), obtaining high resolution of high precision FMM is a priority. In order to manufacture high precision FMM, metal plate of 40um or less is needed, and also requires technology that allows for highly accurate process. Only 2 companies, Japan’s DNP and Toppan, can produce high precision FMM, and since they have exclusive contracts with Samsung and LG respectively, they cannot provide FMM. Therefore, JDI employs WOLED structure that does not require FMM for AMOLED development and commercialization.

 

To develop high resolution AMOLED panel, Tianma has been independently developing dual FMM. Although it has not been confirmed what type of FMM was used for the FHD AMOLED revealed in FPD China 2015, they exhibited 5.5inch FHD OLED product with 400ppi resolution.

 

Resolution of FHD or higher can be realized by manufacturing OLED panel itself purely by process, or by another method with pentile technology. Currently it is difficult to produce FHD with the first method and even Samsung and LG are utilizing the pentile technology. As such, it is likely that Tianma’s AMOLED is pentile driven. Pixel structure needs to be analyzed once the product is available on the market.

[MWC2015] Smart Watch Market, Struggle Expected in Google OS Sector

In MWC2015, various companies, including Samsung Electronics, LG Electronics, Huawei, and Asus, exhibited smart watch. Since 2014, Samsung Elec. and LG Elec. began to sell smart watch, Asus and Huawei are shipping smart watch equipped with rigid AMOLED panel. Apple, a latecomer but also strongest rival, is planning to actively sell smart watch, with LG Display’s plastic OLED, from April.

From the outside, all 5 companies have smart watch with AMOLED, but other than Apple which uses iOS, and Samsung Elec. that uses Tizen, the insides of the other 3 companies are the same. This is because they use Google OS. Hence the software of these 3 companies’ products are similar, and without the smart watch exterior the functions are almost identical. The only differentiations are due to smart watch design. Huawei’s smart watch face design is similar to LG Elec.’s, and the back design practically cannot be distinguished from LG Elec.’s products. 150305_[MWC2015] smart watch 시장, 구글 OS 진영 혼전 예상1150305_[MWC2015] smart watch 시장, 구글 OS 진영 혼전 예상

In MWC2015, Google sector showed how difficult it would be for any company to conquer the market.

[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.

150216_[Analyst Column] AMOLED 탑재 스마트폰이 모바일용 디스플레이 대형화 주도_eng

 

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”.

Samsung Display, to break through crisis with diversification of OLED customer!

Samsung Display is speeding up to be post-Samsung Electronics. The world’s sole OLED panel that Samsung Display manufactures is applied to most of the products by Samsung Electronics’ IM Division. Samsung Display expected to expand the OLED panel market as building the A2 line additionally in 2013 but the Smartphone Galaxy S5 did not measure up to the expectations resulting gradual decrease of factory operation rate a long with the sales.

The diversification of customers is required at this moment in the Samsung Display’s AMOLED panel industry which heavily relies on Samsung Electronics. And the result of those efforts begins to appear in the tablet PC area. In the last month, Dell revealed the tablet PC Venue 8 7000 using the Samsung Display’s 8-inch AMOLED panel (refer to the OLEDNET article posted on November 4), and now Fujitu released the tablet PC ARROW Tab F-03G with 10.5-inch AMOLED panel. (http://www.fmworld.net/product/phone/f-03g/info.html#heading02). Fujitsu is emphasizing the excellent picture quality of the tablet PC with AMOLED panel compared to the product made of LCD.

It has been only half a year since the OLED was applied to the tablet PC and yet, it is anticipated to be applied by a wide range of industries from next year given that global set companies begin to use OLED.
