SEL unveiled the 81inch 8K OLED multidisplay at Finetech JAPAN 2017 held in Tokyo, Japan from April 5th to 7th. The SEL 81inch 8K OLED multidisplay is implemented with 36 (6×6) panels of 13.5 inch wide display.

A SEL manager said, “When multiple displays are attached to one another, it is hard to look a single layer screen due to difference between layers and brightness of the joint parts.”

“For resolving the problem and implementing the seamless image, transparent treatment around the edge and deep learning technology are applied to the 81inch 8K OLED multi display. Deep learning technology compensates for grayscale curves by comparing the brightness of joint parts and partial images excluding the joint parts. ” Additionally SEL unveiled a curved OLED multidisplay that is transparent around edges equal to the 81inch 8K OLED multidisplay.

“A curved OLED panel is as thin as 100 μm, so it has excellent resistance to bending (inward and outward bending) even at 100,000 bends in the curvature radius of the 5R.” The curved OLED multidisplay design can offer a variety of applications to use displays such as car-mounted and digital signage. “said the SEL manager.

In this Finetech Japan 2017, SEL presented curved OLED multidisplay in the form of car-mounted (CID + cluster). The car-mounted display has three –layer 13.5-inch panels and HD (720 x 1028) resolution.

SEL also showed full-spec 8K OLED display and hybrid display with improved visibility to gain positive response from the audience.

Ink-jet printing OLED, Next-generation large-area display

Ink-jet printing OLED is attracting public attention once again as a next-generation large-area display.

At the keynote session of Finetech Japan 2017 held at Tokyo Big Sight as from May 5, CSOT in China prospected that next-generation large-area display would be ink-jet printing. York Zhao, the CTO of CSOT said that when the price of a new product is 1.2 to 1.3 times that of an existing product, it is the right time for the existing product to be replaced with new one. This principle has been applied when the CRT and PDP market was replaced by LCD. He added, “The price of large-area OLEDs should drop 1.2 to 1.3 times lower than LCDs to lead to a full-fledged OLED era, and ink-jet printing technology is the best way to assist the drop in price of OLED.”

In 2016, CSOT established the printing display alliance called “Guangdong Juhua printing display technology” together with Tianma, and has been participated by kateeva, DuPont, ULVAC, Merck and Jusung Engeering.

Following the announcement of CSOT, JOLED introduced various OLED panels in direct application of ink-jet printing. One of the most interesting devices was the ink-jet printing 21.6 inch 4K (3840 x 2160, 204 ppi) AMOLED panel produced in Gen 4.5 line. Yoneharu Takubo, the CTO of JDI said, “Since the establishment of JOLED, we have been improving ppi, and developed a technology to stably produce up to 204 ppi resolution. We are targeting 350 ppi and expand its product range from small and medium to large area to secure a variety of applications with ink-jet printing AMOLED. ”

Ink-jet printing process is a technology under continuous development of major panel makers as AMOLED panel of RGB structure can be manufactured without dividing the ledger in the mass production line higher than Gen8. Also, material utilization efficiency is theoretically close to 100% to save the OLED unit cost. However, some issues arise that mass production has yet to be fully verified, and the efficiency and life span of soluble light emitting materials are inferior to those of deposition materials; hence, there has been undergoing active development in the manufacturers of light emitting materials, equipment and panels.

Ink-jet printing OLED becomes the center of public attention as a next-generation display technology, and when it will be commercialized is a matter of a question.

[Finetech Japan 2017] LG Display OLED, more than 50% of the total revenue in 2020

At the keynote session of Finetech Japan 2017 held in Tokyo Big Sight as from May 5, LG Display’s CTO, Kang, In Byeong said, “LG Display OLED accounted for 10% of the total sales revenue in 2016, but is expected to increase more than 50% in 2020.”

<LG Display, Kang In Byeong CTO>

Currently, large OLED accounts for the majority of LG Display OLED sales. OLED TVs in application of LG Display’s large OLED are positioning as in the premium TV market leader, with approx 80% market share of the 65-inch large TVs priced higher than$ 3,000, and nearly 100% of the 55 inch large TVs higher than $ 2,000.

He said, “While 10 years taken for LCD to achieve more than 80% of market share, two years for large OLED, whose price is falling much faster than LCD. On top of it, OLED attempts to generate a premium markets with high-value-added products such as wall paper, crystal sound OLED, roll-able, transparency and signage. Also OLED for mobile device has been equipped with high competitiveness in application of a flexible design, and market demand has been significantly increased. Consequently LG Display is undergoing active development and investment.” He emphasized that the ongoing challenges will bring the LG Display’s OLED sales result in 2020 up to more than 50% of the total.

LG Display is investing in both the Gen8 large OLED mass production line and the Gen6 plastic OLED mass production line to meet the growing demand for large OLED and plastic OLED (flexible OLED). Regarding future mass production capacity, CTO, Kang said, “In 2020, large OLED production line capacity will be 6 times as big as that of 2016, and for plastic OLED 14 times.”

CTO Kang lastly addressed that the future OLED strategy of LG display is to produce large OLED wider than 77 inches, implement 8K and develop application for high-value-added product market. As for mobile device OLED, UHD resolution, DHK power consumption improvement and distinctive design are the key elements as well as flexibility that can increase the OLED performance and investment efficiency to differentiate from LCD and domineer the next generation display market.

Through the Finetech Japan 2017 keynote, LG Display once again emphasized that OLED is the key instrument to lead the display market in the future. Based on the large OLED technology, LG Display will continue to lead the display market by expanding its scope to mobile device OLED.
