/in /by

UBI Research recently published “2Q18 AMOLED Display Market Tracks”, which includes market updates of the second quarter of 2018. The report covers OLED display panel makers’ investment status, OLED display market forecasts from 2018 to 2022, OLED demand and supply trends, and competitiveness analysis of OLED Smartphone business for Samsung Display and other OLED display panel makers.

The market update, published with the Excel spreadsheet, describes the production line status and the added line status through future investments of the 15 OLED display panel makers worldwide. Also, it describes not only the major OLED application market such as smart phones and TVs, but also the market forecast by country.

The demand for OLED mobile sets (including smart phones and smart watches) in the first quarter of 2018 dropped to 98 million units from 130 million units in the fourth quarter of last year, due to the lower-than-expected performance of the premium smartphone market, where Samsung Electronics’ Galaxy S series and Apple’s iPhone occupy most of the market. OLED mobile set market is to recover gradually until 3Q, when Apple’s new smartphone model is launched, and by the end of 2018, the demand is expected to recover as to the similar level of the same period of last year. In addition, Samsung Display is anticipated to have a positive impact on the recovery of the Smartphone market in the second half of the year by securing competitiveness by lowering the sales price of rigid OLED panel for mobile phone to about US$ 25 to compete with LCD in China.

Consumers' smartphone replacement cycle is getting longer due to the reason that there is no revolutionary change in the new model compared to the past, and the Smartphone penetration in most of the countries except for India, South America and Africa is reaching the limit. Accordingly, the outlook for the downturn is mostly forecasted in the recent smartphone market. There is a growing interest in technology and design to apply a different form factor to revive the market. In this regard, Samsung Electronics' foldable OLED smartphone, which is scheduled to be released later this year or early next year, is expected to create a new momentum. Attention is focused on whether a folding- type flexible display (Dynamic Flexible Display) will be succeeded as a new type of smartphone from the existing edge-type flexible display (Static Flexible Display).

 

UBI Research predicts that the OLED Smartphone market will grow from 430 million units in 2018 to 900 million units in 2022, and the market for foldable OLED Smartphone is to be from about 1million units in 2019 to 18million units in 2022. This reflects the expansion of OLED panel production lines by panel makers such as LG Display and BOE, besides Samsung Display. It will be updated as new applications are developed in future and the Smartphone market moves forward.

In OLED panel market, OLED panel for Smartphone still occupies 91% of the whole market. Samsung Display has accounted for 90% of total OLED panel market performance and LG Display is followed with about 7.8% share.

OLED TVs, which are continuously increasing in demand worldwide compared to the Smartphone market, are expected to be in short supply this year. LG Display, the only OLED TV panel supplier, will continue to invest in production for the next five years. With the recent approval of new production facility for OLED TV panel in Guangzhou, the full-scale equipment move-in is expected this year. In Paju P10 investment plan, it was confirmed that LG Display will invest in OLED TV panel production line instead of LCD line investment which was examined before. Thus, the OLED TV market is projected to grow to US $ 5.6 billion.

Researchers from Korea’s ETRI Institute developed a graphene transparent electrode for OLED display. Especially, they developed the process of patterning a graphene transparent electrode in exact size and shape on a large-sized substrate. Its application to smart watch requiring flexibility will be available.

ETRI(Electronics and Telecommunications Research Institute) has succeeded in developing a display with the electrode using graphene, a dream new-material, rather than using ITO(Indium Tin Oxide) that has been often used as existing electrodes for OLED display.

The successful display substrate is the current world’s largest one of 370mm x 470mm, a 19-inch monitor in size. The thickness of graphene electrodes is less than 5nm.

ETRI expects that if the graphene is deposited on flexible substrate, thin and flexible display will be feasible. Furthermore, it will become the source technology that can be used for manufacturing wearable devices applicable to clothing or skin.

In general, OLED is stacked with substrate, ITO transparent electrode, light-emitting organic layer, and anodized aluminum. The researches replaced typical ITO with grapheme.

In particular, ITO that has been used as existing electrode has a disadvantage of being made of fragile glass. Therefore, the display manufactured with this technology will clear up the problem of fragile transparent electrode.

ETRI developed graphene growth technology and oxide technology to be applied as an OLED transparent electrode by making a large-scale substrate in collaboration with Hanwha Techwin Co.,Ltd, and secured the grapheme transparent electrode fabricating and process technology with the sheet resistance of 60Ω/m² and the transmittance of 85% applicable to OLED. Especially, ETRI developed the world’s first micro-patterning process that is absolutely required for the display process.

Using this technology, ETRI successfully lighted the world’s largest grapheme electrode OLED panel of 370mm x 470mm. The finding of this study, which was published and demonstrated at 『Graphene 2017』, the world’s largest graphene conference held in Barcelona, Spain in early April, 2016, was highly acclaimed.

The researchers started to research grapheme transparent electrodes for OLED, based on the 4-year support of the Ministry of Trade, Industry and Energy(MOTIE) and Korea Evaluation Institute of Industrial Technology(KEIT) from 2012. They successfully developed a 100mm x 100mm OLED panel last year through the recent world’s largest demonstration, starting with a 7mm x 10mm coin-sized one, at the end of 2015, leading to the higher applicability of a grapheme-based display.

They said they will develop the display with a plastic substrate instead of a glass substrate. It is possible to manufacture a wearable OLED device if grapene is attached to plastic substrate, ETRI added.

ETRI’s Flexible Device Research Head Cho, Nam-sung said “The realization of a general expectation that grapheme would be applied to OLED display is very significant. We expect it will be successfully deployed on an commercial scale through large-scale grapheme film, OLED panel technology, and flexible OLED panel technology.”

This technology is expected to edge ahead from the later competitors including China as the core technology that can further increase the level of flexible OLED displays.

After Ministry of Land, Infrastructure and Transport did pre-announcement of legislation about partial revised plan of ‘Regulations on the performance and standards of automobiles and auto parts’ on the 7th, interests in ‘mirror-less automobiles’ having not side mirror (rearview mirror) are getting hot. This is a method of securing eyesight through display screen in the car after installing subminiature camera to car front and rear and also front doors of both sides, and solving blind zone problem which was the defect of existing side mirror and improving fuel efficiency and designs are expected, even though there are problems on functional errors and design development.

Thus, display for mirror-less automobiles is getting attentions as a drive of new market in display market for automobiles. Display fields for automobiles belongs to the industry to which creating high added value is expected because further customization is required compared to mobile and TV. So LGD or SDC panel enterprises are developing products for market penetration, and two companies are known as setting up policy of progressing differentiating strategies differently from Taiwan, Japanese companies by focusing on Flexible OLED especially.

Flexible OLED has thin, light characteristics and a nature to be able to bend, so it is favorable to mirror-less automobiles requiring new designs from free installing aspects. Also, mirror-less is being evaluated to be suitable to the display for automobiles because it can implement high visibility with very fast speed, contrast range, and wide viewing angle. On July 1st last year, Continental Corporation, auto parts supplier, revealed the possibility of better eyesight provision even in dark situations or the rain while introducing several merits of mirror-less automobiles to which 2 OLEDs were applied through its homepage. In addition, Alfred Eckert, Director of the Advanced Engineering department in Continental’s Chassis & Safety Division mentioned “The effects of unwanted optical phenomena such as glare and weak light can also be compensated”

It is expected that we may be able to meet flights with OLED technology soon.

In existing OLED market, display is applied in mobile field and lighting is applied in indoor lighting field, and it was known several companies seem to be proceeding projects to apply it at either rear lamp or dash board area of the automobile.

However, in IFA 2016 held in Berlin Germany, LG vice president of HE Bongseok Kwon had reporter meeting where he said “we are currently in negotiation with two global airlines to install OLED display at front monitor and window, and the period of application must be discussed for not only seats but also including all parts such as windows.

Especially, several companies including Lumiotech, OSRAM, and LG Inotech already introduced technologies for applying OLED in indoor purposes as well as other fields, and third panel companies are known to be developing technologies for engrafting airline industry, so there is much attention of the outcome of new application.

OLED is designed with thin and light characteristics as well as flexibility where it is good at utilizing space without taking up large volume. Due to its characteristics, the installation is easy without location or space restrictions. So if OLED is applied in window then the flight crew can control the light penetration without having to check the window, and also people will be able to check the flight information they desire through display, and diversify the size and shape of the main display and dashboard.

Aside from these visual effect, it is expected to lower the fuel usage by decreasing the total weight of the flight. According to the contents presented in UK governmental emerging institution CPI (Centre for Process Innovation) in 2014, the fixed fuel usage is expected to decrease by applying OLED due to decreased weight of the flight fuselage and fuel, and the fuel consumed by air-conditioning can also be reduced due to low power consumption and heat, as well as the exhaustion of greenhouse gas is expected to be minimized.
