Declining Japan’s Display Industry

The downtrend of Japanese display industry became obvious once again at the Display Innovation. Originally titled as the FPD International, the Display innovation 2014 was renewed with a different name to evoke a fresh wind in the display industry of Japan, only to find that it had failed to draw attention from the interested parties of the FPD industry.

At the FPD International 2013 held last year, about 200 FPD related companies participated whereas only 80 companies exhibited at the Display Innovation of this year, and the scale of the conference was also reduced drastically as implementing the event not in the existing convention center but in a section of the exhibition hall.

It was evident that the Japanese display industry is in the downturn as only Japan Display was joined as a panel company exclusive of the major Japanese panel makers like Sony, Sharp, Toshiba, Panasonic, etc.

However, it presented that the Japanese Display Industry is still alive as Japan Display reveals flexible AMOLED and technical skills to improve response rate of the LCD and color reproduction and real black, etc. of the LCD. And SEL shows AMOLED related new technologies.

EverDisplay, to become the first Chinese company to mass produce AMOLED


EverDisplay (EDO) began the pilot production of 5.6 inch FHD AMOLED panel in October. The FHD AMOLED (1920 x 1080) panel that EverDisplay began to trial produce is a model for the 4G flagship phone using LTPS TFT with the resolution of 394ppi. The thickness and weight is 0.66mm and 12.9g respectively.

Already in the second quarter of 2014, EverDisplay was seeking customers as they succeeded in producing the 5 inch, 5.5 inch, and 6 inch HD panels. At the conference held at Shenzhen in September, they announced the success of producing the 5.6 inch FHD AMOLED panel for the first time and unveiled the panel at the same time. In addition, the 5.6 inch and 1.63 inch AMOLED panels for the wearable device were presented simultaneously.

The 1.63 inch AMOLED panel is 31.28mm x 34.78mm with the resolution of 320 x 320, 277ppi. The feature of the AMOLED panel for the wearable device that the EverDisplay revealed is that it has the same size and resolution with the Galaxy Gear 2 released by Samsung Electronics early in 2014.

EverDisplay aims to succeed in mass-producing the HD AMOLED panel in the fourth quarter of 2014 and the FHD AMOLED panel in February of 2015. If EverDisplay starts to mass produce in the fourth quarter of 2014, they will be the first Chinese Display company to implement the business. And this first step of the Chinese company is not insignificant in the OLED industry which is led primarily by the Korean companies.

Established in Shanghai on October 2012, EverDisplay focuses on the production of small and medium sized AMOLED and it holds 4.5G LTPS TFT line at present.

LG Display, OLED will continue next year

LG Display is focused on the OLED business to take the lead in current market. At the Performance Presentation for 3Q held on October 22, 2014, LGD demonstrated its confidence on the OLED as the future industry-leading business.

Don Kim, CFO of LGD said, “LG Display is developing the OLED business bearing losses for the time being as we are convinced that OLED will be the industry of the future, and anticipate profits to improve next year in terms of OLED.”

Currently LGD is forming a market by exclusively supplying panels for OLED TV. Providing panels for OLED TV to Korea and China, LGD stated that it will expand the market, for instance, securing the Japanese customers in the future.

The technology developed to countermeasure the OLED TV is the QD LCD TV. The strategy in respond to OLED is one of main issues as Chinese companies have unveiled the QD TV and Samsung is expected to release it next year. Regarding this, LGD’s executive director of strategic marketing, Youngkwon Song said that the strategies for the OLED TV will not change by reason of the release of QD TV, and LGD will continue its fundamental competitiveness of OLED which are competitive price and design differentiation attained by constant strategy of removing BLU.

For the investment plan for 4Q, it is anticipated to reduce the investment cost compared to the amount of 3.5 trillion won of last year. Don Kim, CFO said that the investment on LCD will be limited while the investment on the distinguished products like OLED will be about conversion of existing fab.

Despite LGD is taking a favorable turn with small and medium size LCD panels at present, it is expected to continue the preparation strategy through OLED. But it is analyzed that the future plan using LCD is not stable due to the rapid increase of Chinese companies’ capacities and lowering of price.

LGD’s revenues in the third quarter of 2014 is KRW 6,547 billion, increased by 10% compared to the previous quarter, and the operating profit is KRW 474 billion, a quarter-on-quarter increase of 191%. The outlook is that it is due to the increase of the shipments in time with the release of the Apple IPhone 6.

‘The shipment for the third quarter was 9,654Km2 as expected and it was measured against the expected preparation for considering the tight demand-supply status’, said Don Kim, CFO of LGD. Furthermore, as per product, the sales percentage of mobile devices and tablets applying the small and medium panels were accounted for 19% and 12% respectively, a quarter-on-quarter increases of 3% for each.

Samsung VS. LG, to take different OLED strategies

The separate OLED strategies of Samsung Electronics and LG Electronics drew much attention at the Korea Electronics Show 2014 held at Ilsan KINTEX from 14th October.


Samsung Electronics promoted the 105-inch bendable UHD TV with a curvature of 4000R as a major product and implied concentration on LED TV as not exhibiting OLED TV. Meanwhile, the Galaxy Note Edge and 4, and gear S were displayed intensely in the mobile section, suggesting that the mobile is taking the OLED oriented strategy.


On the other hand, LG Electronics received fervent response from the audience as exhibiting the five 77-inch Curved UHD OLED TV and advertised OLED TV providing customers to experience merits of OLED TV at the OLED TV zone set inside the booth. For mobile, only the G Watch R applying OLED was showed without any comment on the following product of G-flex.


This tendency of pursuing disparate strategies began from CES 2014 of this year. Starting from excluding OLED TV from the booth under the theme of World first curved UHD TV, Samsung has stated at IFA 2014 that the concentration is more on the LED not OLED in terms of TV for a while. With regard to mobile, active strategy was devised releasing the Galaxy 5, Galaxy note4, and Galaxy tap S with QHD AMOLED panel and Galaxy Edge with flexible display. LG lowered the price of the 55-inch Curved FHD OLED TV down to $4,000 and implemented dynamic promotion, announcing the release of 55-inch, 65-inch, and 77-inch curved OLED TV. And publicly mentioning the focus on the OLED TV business, LG has highlighted that it will lead the OLED TV market in the future.

LED TV emits three times more harmful blue light than OLED TV

141015_LED TV, 몸에 나쁜 청색 빛 OLED TV의 3뱁


The LCD emits 3.1 times more blue light than OLED, said Choi Dong-won, senior vice president of LG Display at the IMID Display Business Forum held at Ilsan Kintex.

Recently, the harmful aspect of the blue light is suggested in Japan including Europe and U.S. The blue light emits the high-energy light of 380~550nm wavelength. In May of 2012, the Harvard Medical School has announced that the exposure to the blue light at night may keep people up late as well as cause cancer, diabetes, or heart disease, and there was a research regarding the influence of blue light from LED on retina at Japan.

LG Display said that OLED TV emitted 1/3 of blue light than LCD TV, measured under the general household environment.

Mr. Choi also said that the blue light issue will be resolved as the blue light is proportional to the luminance and area, and LG Display manufactures OLED panel for the use of TV changes from 55-inch to 65-inch. He also added that OLED TV is appropriate for Curved TV as it is, unlike LCD, free of light leakage phenomenon.

Samsung Display, OLED is the best for mobile devices

Samsung Display proved that the OLED is the optimum display for a mobile device as launching the new function which is only available in the OLED at the IMID 2014 held at Ilsan, KINTEX.

Samsung Display introduced the ultra-power saving, color weakness, and super dimming which are the functions maximizing the merits of AMOLED.

Ultra power saving mode is a function structuring the screen with black and white as a grayscale display by activating only the parts expressed in white using the OLED feature of operating pixels separately. This function is not offered by LCD which requires to run entire BLU for only one pixel and it is useful in emergency situation as it is possible to use the smartphone up to 8 days with the 63% of battery.

Color weakness mode is a function enabling people with color vision deficiency to distinguish R and G clearly through the display by applying the technology of increasing or reducing the brightness of R and G pixel among the R,G,B sub pixels of OLED and it is also not available in the LCD which uses color filter.

Lastly, super dimming mode is a function providing a comfortable viewing experience without any distortion or dazzle in very dark environments. In the bed room environment, 1~2 nit is reported to be the best nit without dazzle, and while there is a dazzle effect for LCD even in the lowest 8 nit in the bed room environment, there is glaring for OLED that 2 nit is possible, allowing people to watch comfortably.

In addition, announcing the 14-inch AMOLED panel for tablet PC with the resolution of WQUXG, Samsung Display drew a great interests from the audience, attesting Samsung Display’s exceptional technology in mobile AMOLED.

Life of OLED lighting panel, to reach LED

The life of OLED lighting panel is improving equal to the level of LED (more than 50,000 hours).

According to the NIKKEI report, Kaneka developed the OLED lighting panel with a lifetime of 50,000 hours. The panel is 8×8 cm in size and 1 mm thick, and samples are shipped to some lighting companies. Applying enhanced Blue material, the color change due to thermalization has dropped under 40% and the price is about the same.

KANEKA is producing OLED lighting panel with an annual capacity of about 20,000 panels. In the Lighting fair 2013, the company exhibited OLED lighting panels of 50x50mm and 80x80mm sizes in diverse colors of white, yellow, red, green, and blue which are currently sold at about 4,000 yen for the 50x50mm panel and 6,000 yen for the 80x80mm panel.

The OLED lighting panel with the longest lifetime on sale is LG Chem.’s 100x100mm panel with 80lm/W and 50,000 hours.

The UBI Research issued “2014 OLED lighting Report” prospecting the OLED lighting panel market to be open actively from 2015 and reach about US $ 4,700 million by 2020.

Flexible AMOLED battle, Who are going to win?

In 2013, the flexible AMOLED panel was mass produced in Korea for the first time in the world and the smart phone applying this technology was released. With the announcement of smart phones like Galaxy Gear and G watch R this year, the interest in flexible AMOLED industry is rising, developing actively in Korea, Japan, China and Taiwan.

As a front-runner, LG Display of Korea is mass producing the round type flexible AMOLED panel for G watch R along with the groundwork for the 5.5-inch flexible AMOLED panel to be employed on the G flex 2. In addition, the 18-inch flexible AMOLED panel was developed as a part of the national project. Samsung Display supplied 2-side 5.6-inch flexible AMOLED panel for Galaxy Note Edge and 2-inch flexible AMOLED panel for Gear S, and it is planning to mass produce foldable flexible AMOLED panel upon successful development.

The SEL’s research activities are most active in Japan. SEL drew a huge attention at SID 2014 as introducing the tri-foldable, book type, and 13.5-inch 4K flexible AMOLED panels using CAAS-OS backplane.

The Chinese companies BOE and New Vision Optoelectronics launched the flexible AMOLED panel at SID 2014, and as AUO showing the 5-inch flexible AMOLED panel and ITRI presenting the 6-inch foldable AMOLED panel at Touch Taiwan 2014, the companies of Taiwan also joined the development competition.

Accordingly, key companies are in the course of developing the flexible AMOLED panel but the TFT technology exclusively for the plastic substrate (high-resolution/Bezel, power consumption) must be developed intensively for the fabrication on the flexible device in bendable/foldable/rollable form. Furthermore, the technology to lower curvature and encapsulation technologies must be developed along with the miscellaneous flexible components and equipment design technologies.
