RGB ink-jet printing, also applied to small and medium-sized OLED?

/in /by

At the “Year End Seminar of OLED/Display” held at COEX in Seoul, Korea, on December 7, Kim, Seok-Soon, CEO of Unijet said that ink-jet printing technology can implement over 550 RGB ppi and ink-jet printing can be applied to small and medium-sized OLED process as well.

The currently mass-produced QHD resolution of 5.5-inch mobile device is 550 ppi but it is actually 400 ppi with pentile structure. Moreover the ink-jet printing technology for RGB pixels is currently in the range of 150 to 200 ppi which can achieve 8K resolution on over 55inch OLED, yet inapplicable to the small and medium-sized OLED process. As Kim announced, if the ink-jet printing technology is applicable, implementing 550 ppi in the small and medium-sized OLED process, beyond QHD resolution in 5.5 inches, it is possible to implement UHD resolution in pentile structure.

<ppi by size and resolution>

Kim said, “In 2012, single droplet measurement technology showed 2.5% or less of volume accuracy, which was, however, insufficient for RGB printing.  In 2017, the laser droplet measurement technology enabled the discharge volume control less than 0.1 μm and the real-time internal pressure control reduced the volume accuracy by less than 0.1%.” Kim added that it is possible to form over 550 RGB ppi regardless of the pixel structure.

Lastly, Kim noted that the solvent purity for OLED RGB pixel is very important; “Inkjet printer can be commercialized only if ink materials are fully developed first to satisfy panel makers. He expected that it will be applied to the mass production line in earnest since 2020. ”

Based on the unique technology of set makers, it is worth noting that OLED TVs with what kind of characteristics and advantages will be produced.

Solution Process OLED, Max. 40% Decrease in Component Material Cost Possible Compared to WRGB

/in /by

According to 2017 Solution Process OLED Annual Report published by UBI Research, when solution process (ink-jet printing) is applied to large area OLED, it could reduce up to 40% of component material cost, and approximately more than 18% of production cost compared to WRGB process that uses evaporation method.

 

Solution process is a technology that can manufacture RGB pixel structure of large size OLED panel without cutting mother glass using Gen8 manufacturing equipment or larger.

 

UBI Research analyst Hyunjun Jang explained that the solution process applied OLED has a simpler panel structure with 5 layers compared to 20 layers of WRGB OLED. WRGB OLED process material usage efficiency is only at 40% but solution process application could increase this to over 90%. Jang added that the lack of color filter is a factor that could decrease panel production price by reducing development cost. Particularly, this can greatly reduce emitting materials usage which occupies much of materials cost and contribute considerably to the fall in production cost. Furthermore, he added that cost setting of soluble emitting material per gram will be an important factor in production cost decrease and emphasized that organic material usage greatly decreases when soluble emitting materials are used but must consider price increase due to solvent cost, production cost, and development cost.

 

Solution process technology continues to receive attention as a key technology that can lead popularization of large area OLED, and key AMOLED panel companies are carrying out development.

 

In terms of technology, solution process OLED has lower emitting efficiency and short lifetime as diverse solvent is added to existing evaporation materials to transform into ink leading to low purity. This has been an important issue for panel and material companies for past several years. To improve this, DuPont, Merck, Sumitomo Chemical and others have been actively developing soluble OLED emitting materials. Much like evaporation materials, blue materials showed particular difficulty in performance improvement. However, at present significant portion of technology development has been carried out and investigation shows approximately 80% of lifetime and efficacy of has been achieved compared to evaporation materials.

 

2017 Solution Process OLED Annual Report compared and analysed WRGB OLED and solution process OLED’s competitiveness in terms of process, materials, and cost. Key issues, soluble OLED emitting materials development status, key companies’ trend, and solution process OLED market are analysed from various perspectives.

Is there possibility of High resolution(UHD) OLED Smart-phone generation?

/in /by

Recently VR contents experience through smart-phone device has been increased, therefore high resolution of smart phone is becoming necessary. However, OLED smart-phone resolution still remains at QHD level for 3 years since QHD OLED is applied to Galaxy Note 4 for the first time in 2014.

The core point that decides resolution of OLED smart-phone is evaporation process for emission layer. Bottom-up type evaporation method, which is applied to the recent devices is that substrate and FMM (fine metal mask) are horizontally arranged on the upper side of evaporator and vaporize the organic material from the lower linear source in order to form RGB layer.

Thin FMM measures less than 15um thick is necessary for making high resolution OLED like UHD level, however, as FMM gets thinner, it would be difficult to make mass production because technical problems will be occurred such as patterning, sealing and welding.

In order to solve these problems, various metal mask patterning technologies are being developed such as vertical type evaporation and plane source evaporation.

Vertical type evaporator that arranges board and FMM vertical is developed by Hitachi of Japan for the first time. And Canon Tokki exhibited Gen6 vertical type evaporator at Finetech Japan 2013, however it is not being used for mass production at the moment.

<Canon Tokki’s Gen6 vertical type evaporator which is exhibited at Finetech Japan 2013>

According to the recent ETNEWS, Applied Materials developed Gen6 flexible OLED vertical type evaporator and it is being tested in Japan Display.

Plane source evaporator is being tested but also the linear source type. Plane source evaporator method is that an organic material is first evaporated on the metal surface to produce plane source, then re-evaporated in order to form an organic thin film on the substrate.

In the past iMiD 2017, representative of OLEDON, Chang Hoon Hwang mentioned that 2250 ppi resolution OLED can be implemented through plane source evaporator.

For metal mask patterning technology, electro forming and laser patterning technology is highlighted. Electro forming method is developed by Wave Electronics, TGO Technology, Athene and so on. Laser patterning technology is being developed by AP Systems.

As such, development for high resolution OLED is receiving great attention whether it can solve the current problems and contribute to UHD resolution implementation for OLED smart-phone.

Cynora, TADF will contribute to high-resolution implementation of OLED devices and panel cost reduction

/in /by

At the Global Materials Tech Fair 2017 held on September 22 in COEX, CEO Ko Chang-hoon of EM Index, Cynora’s Korean partner, announced the development of the thermally activated delayed fluorescence, blue TADF, which is currently under development at Cynora.

<CEO Ko Chang-hoon of EM Index>

Generally, the blue light emitting material is insufficient in life and efficiency compared to red and green. For this reason, OLED panels for mobile devices are manufactured relatively large in blue pixel size compared to other pixels, in the OLED panel for TV, blue light emitting layers are laminated twice. The blue TADF is the material that is being developed to overcome the limitations of this blue light emitting material.

CEO Ko Chang-hoon mentioned “Applying blue TADF increases lifetime and efficiency, so it does not need to increase pixel size and it is advantageous for high resolution implementation” and emphasized “In mobile devices, it will be advantageous to reduce power consumption as well as realize high resolution and in case of TV, it will be advantageous to reduce the panel cost because only one layer of blue light emitting layer needs to be formed.”

He referred to the recent investments of € 25 million from Samsung Venture Investment and LG Display and explained that it was a proof that blue TADF is attracting a lot of attention.

It is also close to the efficiency, lifetime and color purity of the blue TADF required by major OLED panel makers and is expected to meet these requirements by the end of 2017.

<Cynora’s blue TADF development progress>

Finally, the company announced the development roadmap for the green TADF by the end of 2018 and the red TADF by the end of 2019, and concluded by emphasizing that TADF would contribute to high-resolution implementation of OLED products and panel cost reduction.

Fraunhofer Institute will introduce automotive flexible OLED lighting at ISAL 2017

/in /by

Specialized in development and manufacturing OLED module, Fraunhofer Institute will introduce Automotive flexible OLED lighting with adjusted color at ISAL 2017 which will be held in Darmstadt, Germany from 25th to 27th September. Fraunhofer Institute had released previously OLED which the color can be adjusted by rigid substrate in 2015.

Fraunhofer Institute has continued to develop flexible OLED lighting since then. Flexible OLED lighting which will be shown at ISAL 2017 is known to be changed to yellow and blue color. It can be shown as white light by making of yellow and blue color at the same time.

Fraunhofer Institute predicts that flexible OLED lighting will be replaced for car interior lights and it could also be used on the ceiling or winding parts where lights cannot be built easily. Commercial lighting is required to have heatsink and unfortunately it can not be easily built with lack of flexibility in design. However flexible OLED lighting is very light and thin which means it is expected to be widely used for Automotives interior with its flexible design. Fraunhofer Institute also made a comment that they may produce flexible OLED substrate glass, metal and plastic film as well.

OLED lighting has been recently used for Automotives interior and it is expected to be used more in the next generation. Customized Automotive service company, Changscustom showed OLED lighting built in the car at Seoul Auto 2016. Furthermore lighting companies including LG Display and Osram supplied OLED tail light with Mercedes-Benz and BMW.

Meanwhile, according to 2017 OLED Lighting Annual Report which was recently published by UBi Research, using of Automotive OLED Lighting will be increased to $2.11 billion in 2025 from $6.4 million in 2017 with 107% of growth rate. Especially flexible OLED Lighting is expected to capture a higher market share more than 95% and flexible OLED Lighting will be widely used instead of rigid OLED lighting.

Starting to have mass production process in Gen5 OLED of LG Display from end of September, lighting market is expected to reach full growth. The growth of OLED lighting market is being watched with keen interest to compare with strong growth of OLED display market.

UBI research publishes 2017 OLED lighting report : LG Display, ready to mass-produce OLED light panel, expecting OLED lighting market to grow fast

/in , /by

LG Display starts mass production of 5G OLED panel for lighting from the end of September

■ OLED lighting panel market is projected to grow from US$ 1.9billion in 2021 to US$ 5.8billion by 2025

 

LG Display will start mass production of 5G OLED light panels from the end of September, therefore attention is focused on whether the OLED lighting market is growing rapidly. According to LG Display, monthly production capacity is 15K, and it is to be increased to 90K later.

 

According to the ‘2017 OLED Lighting Annual Report’ published by UBI Research on August 8, the global OLED lighting panel market is expected to grow to about US$ 1.9 billion by 2021. Furthermore, it is projected to have a CAGR of 85% for the period 2017-2025, and form a market of US$ 5.8 billion in 2025.

Because OLED lighting is thin, light and flexible, it does not limit the installation space and has excellent design autonomy. In addition, OLED lighting is used for automotive, exhibition, and medical as well as general indoor lighting because it can create a comfortable atmosphere with little heat and flicker.

 

However, the market for OLED lighting has been slower than that of OLED display, which is widely applied to mobile devices and TVs. Osram focuses primarily on automotive OLED lighting, and Philips sold its OLED lighting division to OLEDWorks. Also, Japanese panel makers such as Sumitomo Chemical and Konica Minolta have developed OLED lighting for industrial and medical applications. Nevertheless, it seems to take time for OLED lighting to become eventually a large market.

With LG Display’s mass production of Gen5 OLED line, the price of OLED light panel is estimated to drop below US $ 10 (100 x 100 mm). The significant price competiveness might enable OLED panels to be applied to various areas such as automobile and display lighting as well as indoor lighting. Owing to this expectation, attention is focused on whether the OLED lighting market, showing signs of slow growth, can be materialized.

UBI Research predicted that LG Display would account for about 70% of the world’s lighting OLED panel market in 2017, and will continue to lead the OLED lighting panel market with a 50% market share in 2020.

 

Meanwhile, ‘2017 OLED Lighting Annual Report’ describes trends of next-generation lighting market, promising applications, cost analysis upon the investment of LG Display and forecast of OLED lighting market. Since it analyses particularly OLED lighting market, materials market, and equipment market forecasts for OLED lighting from various perspectives, it is expected to help the related companies identify the OLED lighting market.

Material Science to develop blue dopant for OLED … OLED Efficiency ⋅ Lifetime Up↑

/in /by

A Korean venture company has succeeded in developing blue dopant for Organic Light Emitting Diodes (OLED) that a Japanese company has had its exclusive patent for. The dopant is an element that improves efficiency and life time by mixing with host that actually colors within the OLED.

In the meantime, many domestic material companies have developed OLED host, but it is the first case that a venture company has independently developed dopant on a commercial scale without receiving any support of large corporations.

 

Material Science (CEO Lee Soon-chang), an organic material developer for OLED has developed a technology that can replace Japanese I Company’s patent for blue dopant. Established in 2014, Material Science is supplying HTL( Hole Transporting Layer) and ETL (Electron Transfer Layer) to OLED panel makers.
Half of the 50 employees are R&D personnel. Last year, its sales were 6.6 billion won, and it is expected to exceed 10 billion won this year.

This time, due to the development of blue dopant by Material Science, OLED panel companies have an alternative to supply blue host and dopant besides I Company.

Japanese I Company has been developing blue dopant since 1995. At present, the company has more than 30 patents related to blue dopant (based on Japanese application for a patent), and its major 8 patents are valid until 2034. In particular, it has an exclusive patent for the combination method of blue dopant that includes blue host and pyrene with an anthracene structure (a compound in which three benzene rings are sequentially bonded). For this reason, the panel makers which purchase dopant from I Company must buy its host. If they mix I Company’s blue dopant with another company’s host, it is inevitable to infringe the patent in the case a host material has an anthracene skeleton.

Both Samsung Display and LG Display have been using I Company’s blue dopant and host.

The blue dopant developed by Material Science is designed to make molecules that are completely out of I Company’s compound patent. Conventionally, the method of applying an electron acceptor to a molecule has been used to improve the efficiency and lifetime of OLED and have a blue color.
On the other hand, Material Science introduces electron donor into molecules to improve the efficiency and lifetime while generating dark blue color. This dopant greatly reduces the solvent-dependent color development (solvatochromism) where emission wavelength changes due to the polarity of the surroundings. Therefore, the change of emission wavelength is also greatly reduced.

Jung Jae-ho, a researcher at Material Science said, “We have developed a new structure and a synthesis method, which makes it possible to produce its differentiated dopant.” “Panel companies are now able to utilize various types of blue hosts”. In addition, Material Sciences has been recently developing TADF(Thermally Activated Delayed Fluorescence) that OLED panel makers are struggling to introduce for the longer life of blue-emitting phosphors.

<OLED emitting material market forecast, UBi Research>

According to UBi Research, the OLED organic market is expected to reach $ 3.36 billion by 2021 (about 3.8 trillion won). And blue materials account for 11.5% of total sales.

[iMiD 2017] LG Display, Spur Development of 77 inch transparent flexible OLED

/in /by

LG Display’s Kwon Se-Yeol senior researcher introduced the 77-inch transparent flexible OLED which had been introduced in June at IMID 2017 held in BEXCO, Busan on Aug. 30, and announced the applied technologies to realize this.

Kwon Se-Yeol senior researcher mentioned, “OLED is self-luminous, so it can be manufactured with a thin thickness because it does not need a back light unit. The thinner the thickness, the more flexible the OLED can be so that it is easy to implement flexible displays with OLEDs.” and forecasted. “It can be used in various fields such as signage and smart desk.”

The 77-inch transparent flexible OLED which is released this time is a top emission type for improved luminance. The transparent thin film encapsulation layer is applied, different from the conventional OLED TV or large flexible OLED, and two polyimide substrates are used.

Kwon Se-Yeol senior researcher said “We applied a transparent thin-film encapsulation layer instead of the existing metal encapsulation layer for the top emission method ” and explained “A white OLED light emitting layer and a color filter layer were formed on two polyimide substrates and cemented together. A barrier film and a multi-barrier were applied to the top and bottom of the polyimide substrates to prevent moisture and oxygen penetration.”

The Kwon Se-Yeol senior researcher then states that “flexural rigidity of the panel is mainly affected by the thickness of the polarizer and the encapsulant layer, so it is necessary to reduce the thickness in order to improve the flexibility”, and emphasized “By reducing the thickness of the encapsulant layer from 100 μm to 20 μm, we can reduce the strain on the OLED module from 0.36% to 0.21%, along with improved flexibility”.

In addition, he mentioned that surface reflection due to polyimide birefringence phenomenon, laser wavelength selection according to polyimide properties in LLO (laser lift off) process, and use of flexible OLED module are all covered, and technical development is continuing.

Meanwhile, LG Display has developed the world’s first 77-inch transparent flexible OLED with UHD (3840 × 2160) resolution, transmittance of 40%, and radius of curvature of 80R as part of the national project.

[iMiD 2017] OLEDON, Disclose plane source FMM deposition principle for 2250ppi OLED manufacturing

/in , /by

Prof. Hwang Chang-Hoon, CEO of OLEDON, a venture laboratory of Dankook University, presented a plane source FMM deposition technology capable of implementing 2250 ppi at iMiD 2017 held on the 28th.

According to Prof. Hwang Chang-Hoon’s presentation, the plane source deposition technology developed by OLEDON differs from the existing organic material deposition method. The plane source FMM deposition technique is that the organic material is first deposited on the metal surface to form a donor film and then re-evaporate it to form an organic thin film on the substrate. Applying this technique, organic matter forms a vertical gas beam due to plane evaporation. (Source patent: 1012061620000 Republic of Korea)

The shadow distance when organics are deposited with a plane source developed by OLEDON is 0.38 μm – 0.59 μm. This is a level at which a 2250ppi device having a pattern size of 4 um can be manufactured.

Prof. Hwang Chang-Hoon explained ‘applying the plane source deposition technique reduces the incidence angle of the organic material and dramatically reduces the shadow caused by the mask’. In addition, ‘using a plane source, the perpendicular organic gas beam can form a completely zero incident angle, so theoretically, the shadow distance can be zero um’.

<Principle of plane source deposition technology developed by OLEDON>

In addition, Prof. Hwang Chang-Hoon emphasized that ‘plane source deposition technology is essential for high-resolution shadow masks’.

For linear source FMMs currently in production, the shadow mask opening distance is 80 μm. As a result, the incidence angle of the organic material gas is inevitably large, making it difficult to produce a shadow mask having a high density pattern.

Prof. Hwang Chang-Hoon explained, ‘Using plane source deposition technology, shadow mask taping angle is 80 ° level’, and the distance between openings can be reduced to less than 20 μm so that plane source deposition techniques can solve the mask pattern density problems of linear sources’.

OLEDON is challenging fully shadow-free patterning conditions with plane source deposition technology, and plan to develop and install a plane source FMM evaporator capable of manufacturing 11K class micro OLED devices in cooperation with Prof. Jin Byung-Doo in Dankook University. (Reference: Homepage of OLEDON www.oledon.co.kr)

<The opening density change of the shadow mask when the plane source FMM deposition technique is used>

Meanwhile, OLEDON has 13 registered patents for plane source FMM deposition for mass production. Based on recent research results, they filed 7 new patents for mass production equipment in Korea and 3 applications are filed for PCT international application.

[iMiD 2017] AP Systems, Find FMM answers through USPL

/in /by

At iMiD 2017 in BEXCO, Busan on 28th, AP Systems announced that it succeeded in developing 1000ppi FMM with USPL (ultra-short pulse laser).

Since FMM plays a role of depositing pixels and RGB organic materials, FMM serves as a factor that determines resolution and yield of OLED. At present, FMM is mainly manufactured by etching method. This method has a problem that a shadow phenomenon due to the precision, thickness, and weight of the fine pattern occurs, in order to solve this problem, various FMM manufacturing processes such as laser processing and electro-forming have been developed.

Among these, laser processing method has an issue of forming burrs around pin-holes due to the thermal effect caused by laser irradiation. These burrs increase the shadow interval of the FMM, which causes overlapping of patterns during RGB organic deposition, thereby degrading the resolution of the OLED.

AP Systems has developed a burr-free laser process that does not have burr phenomenon and further controls the taper angle.

The Burr-free laser process is a short-time irradiation of unidirectional pulses at a constant number of times, since the laser is not continuously irradiated, it minimizes accumulated heat energy and prevents burr formation. In addition, by controlling energy of the laser, it accumulates energy and forms taper.

In this way, AP Systems explained ‘they produced FMM with various shapes of fine pin-holes such as square, diamond, and polygonal shapes, as well as 1170ppi FMM’, and ‘’We also developed large-area FMM manufacturing equipment with USPL method’.

AP Systems also added ‘multi-beam and USPL is equipped for FMM manufacturing equipment so that it can improve productivity and realize UHD’.

Since the launch of the Galaxy Note4 in 2014, the OLED resolution has remained at the QHD level yet. In order to manufacture an OLED having a high resolution (UHD level or higher), it is necessary to solve various technical problems faced by FMM. Accordingly, it is noteworthy how USPL technology of AP Systems will affect the future OLED market.

TCL’s Xiaolin Yan CTO addressed solution process OLED TV and self-emitting QLED TV as premium TV after white OLED TV at iMiD 2017 keynote address in BEXCO, Busan on 29th.

Yan CTO noted that white OLED TV, which is currently leading the premium TV market, meets all the requirements of premium TV due to its superior image quality, design differentiation, high resolution realization and nature-friendly characteristics compared to QD LCD TV.

In addition, the price that is higher than the current QD LCD TV is expected to be overcome by applying the solution process, and mass production is also expected in 2019.

Yan CTO predicted that the “solution process would be easy to produce 75-inch panels at Gen 10.5 because the process can be performed without splitting the ledger,” and “it is also possible to produce full-emission RGB OLED TVs.” However, he emphasized that the compatibility of materials and equipment and the development of ink forming process technology should be done.

Following to that, “QLED structure is very similar to OLED structure, so it is easy to apply the technology because of the low entry barriers,” he said. “The lifetime and efficiency of the blue light emitting layer compared to the current OLED is very low, and performance must be ensured without the use of cadmium.”

Lastly, He mentioned the establishment of printing technology in Guangdong JUHUA to promote the commercialization of solution process OLED TV and self-luminous QLED TV, and emphasized the cooperation of material, equipment and panel makers to develop next-generation premium TV.

What is the future of OLED?

/in /by

Choong Hoon Yi, president of UBI Research made a keynote speech with a theme “The Future of OLED” at ‘The 3rd OLED Korea Conference’ hosted by UBI Research for two days from March 8 to 9.

Choong Hoon Yi, president of UBI Research stated “100-inch rollable wall TV is the future of OLED”. “human eyes have a wide viewing angle so even if display covers the whole wall, there is no discomfort. Glass substrate OLED may be difficult to carry, and accordingly rollable display can be rolled up and delivered like a carpet.” he added.

He also predicted “plastic substrates and printing process for price cut will be suitable for rollable display. TFT and pixel production techniques made by Solution process will be a key to future technology”. If a speaker is built in rollable display, and a correspondence between the person and sound on the screen will represent a perfect display.

Choong Hoon Yi said the reasons for the success of OLED can be found out in the mobile market.
Firstly, 4K contents to be used for future TVs will be used in smartphones, and smartphones will also use 4K resolution.

Second, Apple will release the OLED iPhone this year, and there will be an Apple effect because Samsung Display is building the A3 line for Apple to produce 200 million 5.5-inch OLED displays.

Third, Chinese market accounts for 40% of the global smartphone market, and Chinese set companies have been rapidly increasing the release of smartphones.

Lastly, a flexible OLED to cover the full screen smartphone will have no home button and feature wide screen to satisfy visual functions, and its strengthened security system that reads fingerprint and pattern can be applied.

For the four reasons above, he expected OLED will be key in the future mobile market.

Meanwhile, he expected the shipments of OLED panel will be 1.7 billion in 2021, and the sales will amount to US$ 75 billion. Korean display companies will represent more than 80% of the total market in 2021, and China will take up 10~15%. In addition, he forecast that display panel companies will make a new investment in flexible OLED which will account for 70% of the total OLED market.

<Lee Woo-keun, a senior researcher at LG Economic Research Institute>

Lee Woo-keun, a senior researcher at LG Economic Research Institute, predicted that the year 2017 will be an important year to be able to emphasize the innovation of OLED to consumers, in the seminar for the 2016 OLED evaluation held at the Yeouido Small & Medium Business Center in Seoul, hosted by UbI Research on last December 2.

He added “LG is leading the OLED TV market in the premium TV market ahead of next year’s CES, but we will have to keep an eye on the impact of Sony’s joining” as one of the notable issues in large-sized OLED panels, and he continued “as there is still a fundamental expectation for Sony’s image quality among existing consumers, we will have to pay attention to what innovative appearance Sony’ OLED TVs will show and how they can appeal to consumers.

Referring to the adoption of OLED panels in Apple’s iPhone8 (tentative name) in the mobile phone market, as a small and medium issue, he said “it is important how to realize OLED display on Apple iphone 8, and how much impact it will have on consumers through this”. He said “if we could not show the innovation distinguishing it from existing LCDs despite adopting OLEDs, consumers’ expectations for OLEDs may be diminished,” emphasizing that it should draw meaningful responses to OLEDs from consumers’ perspective .

It is expected that Apple will launch iPhone applying flexible AMOLED panels in 2017, and Sony is also being confirmed to continuously review its entry into the OLED TV business. In 2017, it is expected that the number of set-makers launching OLED-applied products will increase more. In the situation that consumers are expecting a ‘completely new thing owned only by OLED products’, which is entirely different from existing LCD products, through various media reports and rumors, the year 2017 seems to be an important year to emphasize the innovation of OLED and to promote its merchantability.

LG Electronics, OLED TV volume of sales 2 times in the 3rd quarter

/in /by

LG Electronics revealed that OLED TV volume of sales was enlarged two times than last year through the conference on the third quarter performance having been progressed on the 27th, and currently OLED TV occupied over 10% among total TV sales. Also they expect that volume of the fourth quarter will be increased two times vs. the third quarter.

Regarding countermeasures on quantum dot TV of Samsung Electronics, they have no notion of competing prices with OLED TV, and emphasizes that they will strengthen recognition such like best TV is OLED TV by thoroughly sustaining premium strategies. They explains that market position of OLED in the market of over USD 200, or USD 300 has been actually increasing rapidly

HE Business Division achieved operating incomes (381.5 billion won) and sales profits of top levels (9.2%) in the third quarter. Sales amount was 4 trillion and 141.5 billion won, and there was not large change with previous quarter (4 trillion and 157.2 billion won).
LG Electronics forecasts that TV demands will be increased due to entering high-demand season in the fourth quarter, and needs on premium products such as OLED TV and UHD TV will be expanded further vs. previous quarter centering on the advanced market especially. Though profitability is expected to be decreased vs. previous quarter owing to effects from increases of panel price and expanded marketing expenses, they reveals their willingness such like responding to seasonal demands on large-size premium products including OLED TV and UHD TV etc. will be made successfully.

Meanwhile, according to UBi RESEARCH, they forecasts that OLED TV in premium TV market will achieve high-speed growth while forming the market of 69.1% in 2012 from 16.7% in 2016.

WOLED will lead premium TV market after 2020

/in /by

UBi RESEARCH held ‘An Analytical Seminar on OLED Market Entry Feasibility of QLED and Solution Process’ on the 14th at Seoul Small& Medium Business Center.

CEO Lee Chung-hoon of UBi REARCH said “OLEd TV will show 16.7% market share in 2016 at the world premium TV market, and lead premium TV market with 68.1% share in 2020.” and analyzed such like “LCD TV could not follow OLED TV performance excluding low price and high solution.”

China is threating domestic LCD market in current wide TV market while displaying material superiority to LCD industry, and cost-effective rate of the wide TV is losing ground to Chinese products too. Thus, LG Display and LG Electronics did successful market entry after having equipped with competiveness in the premium market through OLED TV, and they are expediting mass-production investment and technical development aiming at dominating and popularizing premium TV market.

The most important factor in popularizing OLED TV is price. ASP (average sales price) of UHD OLED panel based on second quarter of 2016 is USD 720, and FHD OLED panel is approximately USD 450. It was expected that UHD OLED panel could lead TV market if it secured about USD 500.

Development to adopt solution process methods has been progressed in order to lower price of wide OLED panel in the industry, and QLED technology as an alternative of OLED TV is becoming an issue nowadays.

In relation with this, CEO Lee Chung-hoon forecasted like “As much as being closed to commercialization due to development of solution process OLED or QLED technology, WOLED technology becomes to be developed one step more, so market entry of solution process OLED and QLED will not be achieved easily. Specially, there are many technical issues in QLED which is considered as next OLED by Samsung Electronics, and 10 years of research will be required further.”

Also, he emphasized that the technology of being able to reduce cost vs. WOLED such as lessening layer numbers dramatically etc. should be developed in order to enter solution process OLED and market successfully, and the entry shall be made by targeting low-end market. In particular, he analyzed that WOLED would lead premium TV, and solution process QLED and QLED occupy the low-end market after 2020.
