Also, Toshiaki Arai, chief technologist of JOLED announced that they would target the middle-sized OLED market with solution process OLED, at the 2018 OLED Korea conference hosted by UBI Research in March.

 

TCL announced “Establishing large-area OLED panel production plant”, is solution processed RGB OLED mass production accelerated?

China TCL will invest RMB 42.8 billion (US$ 6.71 billion) in Shenzhen to establish a factory for large-area OLED panel production. According to South China Morning Post, TCL recently announced that it will produce 90,000 units on the basis of 70-inch panel in the new production line of Gen 11 (3370 mm x 2940 mm) with the goal of mass production in March 2021 in the data submitted to the Shenzhen Stock Exchange. The main products are to be known as 65-inch and 75-inch OLED panels, and 65-inch, 70-inch and 75-inch display panels with 8K resolution.

TCL will form a partnership with the China Development Fund for the necessary financing and will set up a new production line at TCL’s semiconductor subsidiary with RMB 20.3 billion.

Large-area OLED to be produced by TCL is expected to adopt solution process RGB. At the ‘4th OLED Korea conference’ hosted by UBI Research in March, James Lee, deputy chief engineer of TCL mentioned about the development of next-generation premium TV with the screen size of 70-inch or more and 8K resolution, based on the solution process.

Lee said, “The price difference between OLED TV and premium LCD TV is estimated to be reduced to 1.4 times when the price of large-area OLED panel is lowered by the operation of LG Display’s Gen 10.5 plant in 2020. We are developing solution process technology for large area OLED and it will be applicable to Gen11 factory. ”

Gen 11 production line is capable of producing six sheets of 75-inch OLED panels, being able to achieve a yield three times higher than Gen 8.5 production line and a cutting efficiency of over 95%. In addition, it is possible to produce large-area OLED panels with a real RGB structure instead of the WRGB structure when solution process is applied. Based on this, TCL emphasized that the construction of the Gen 11 solution process OLED mass production line is essential. Meanwhile, TCL has jointly established JUHUA Printing Display Technology with Tianma, a Chinese company, in 2016 through CSOT, which is a subsidiary of TCL, and is continuously developing the inkjet printing process by a Gen 4.5 R&D pilot plant.

 

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

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.

What is the future of OLED?

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.

UDC Introduced Organic Vapor Jet Printing That Keeps the Life time and Efficiency of OLED Emitting Material

Mike Hack, vice president of UDC introduced solution process technology, OVJP (Organic Vapor Jet Printing) technology during the COLOR IS UNIVERSAL Session of “The 3rd OLED KOREA CONFERENCE” hosted by UBI Research.

Mike Hack emphasized “OVJP technology can still use OLED materials used for the deposition process unlike the existing ink-jet solution process, and FMM and solvent are unnecessary”.

Besides, he introduced UDC’s Novel BY Display Architecture. According to his announcement, this structure has increased the mask opening size for one-time 2 pixel deposition. Also, Novel BY Display Architecture features the alternate deposition of blue and yellow sub pixels instead of existing RGB, and red and green CF in half of yellow sub pixel is arranged in a vertical symmetrical fashion.

Mike Hack said “This structure maximized not only the fill factor of blue and yellow sub pixel but also the color reproduction rate, efficiency and life time of OLED panel”. He also mentioned it can reduce manufacturing costs due to the use of less than 3data per pixel and 2-step EML deposition(FMM).
Lastly, UDC closed its announcement adding that they aim at the development and commercialization of PH emitter and host.

Meanwhile, according to “Market Entry Analysis for Solution Process OLED” by UBI Research, the emitting material used for the ink-jet solution process employs a method of mixing various solvents in an emitting material used for the deposition process. It lowered the purity of a materials, thereby reducing emitting efficiency and life time. Despite this advantage, solution process can increase the usage efficiency of emitting materials without using color filter and manufacture large-screen OLED panels via RGB pixel structure without panel split through over Gen8 equipment. Due to this advantage, major panel companies are actively developing it and trying to achieve the preoccupancy of commercialization.

Solution Process OLED TV is prospected to be launched on the market in 2019, targeting the Mid-end TV Market

According to “Market Entry Analysis for Solution Process OLED -The Possibilities and Opportunities” issued on November 14 by Ubiresearch, OLED TV, produced in solution process method, is prospected to be launched on the market in 2019.

Solution process is a technology which enables producing OLED panel in RGB pixel structure without any panel division on a device higher than G8, which major AMOLED panel producers has actively engaged in developing.

However, lamp efficiency and life cycle have no option to decrease because luminescent materials have lower purity than that of evaporation materials as luminescent materials applied to solution process should be mixed with various solvents in order to make the existing evaporation materials ink. Nevertheless, why major panel producers has actively engaged in developing solution process is that production cost can be declined as the usage efficiency of luminescent materials is high without using color filters and its structure is simpler than that of OLED panel using WRGB method.

According to the report, it is said that although developing luminescent materials for solution process OLED has been fully engaged, it should be more efficient than that of WRGB methods so as to enter the premium market. However, it seems substantially difficult that the capacity of solution process OLED surpasses that of WRGB as WRGB has been developed in top emission structure to improve its efficiency by over 20% and evaporation materials have also constantly been developed. Rather, based on proper level of life cycle and efficiency, it would be competitive to replace LCD targeting the mid-end TV market, according to the report.

Issues on OLED, QLED, hybrid QD, which can be applied to solution process and possibilities to enter the market, comparative analysis on the capacity of present solution process OLED, supply chain of QD industries, and major soluble OLED material producers are included in this “Market Entry Analysis for Solution Process OLED -The Possibilities and Opportunities” and it is expected to help the relevant producers understand the solution process industry.

Meanwhile, it is predicted that the market of large-scaled solution process OLED panel over 55 inch will begin in earnest being mass-produced as of 2019 and have accounted for the entire wide OLED panel market by approximately 15% growing by approximately US$ 1,000 million by 2021.

When 55inch OLED TV below US$ 1,000 will be realized?

At an analytical seminar on market entry potential of OLED and Solution Process OLED having been held in Small& Medium Business Center on October 14th, Manager Jeong Seong-jin of DuPont had time of introducing tendency regarding soluble OLED material and contents of the latest development.
Manager Jeong said that soluble OLED material and processing technology were on the verge of completion, but problems about how to complete Solution Process by combining it was still remained as issues, and also stated that Material performance (T95>9k hr, CE>25 cd/A) and Uniform printing (SRU>0.95), Contain (performance 90% of flood print), Conformal Drying (luminance aperture>95%) would be key elements.

<4 key elements to make commercialization of Solution Process>

Dupont progressed R&D on Solution Process previously by utilizing Nozzle Printing method that used Surface Energy Modification. This method had merits such like controlling quantity was easy and the nozzle was not clogged up due to constant supply of solution, there were limitations according to panel material together with a lot of raw material consumption.
Dupont lighted up a fact that R&D has been progressed to the direction of deposing organic materials after forming Bank with Ink Jet Printing method owing to such problems and Ink Jet market having been enlarged recently, and then opened Ink Jet Material performance.
When comparing with datum pronounced in 2016 2nd OLED Korea Conference by Dupont, the life seems to be developed for Red and Green in priority, and efficiency for Blue. Approximately 6% of Red life and two times of Green were improved, and about 10% of Blue efficiency was turned out to be increased.
Manager Jeong Seong-jin put emphasis by saying “In order to expand market to OLED from display market having been enlarged gradually, adoption of Solution Process is essential, and concentration for developing soluble OLED luminescence material will be made so that 55inch OLED TV below US$ 1,000 could be produced massively until 2020 by using Solution Process in set makers.”

WOLED will lead premium TV market after 2020

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.

[Lighting Japan 2016] What is the Key Issue of Solution OLED Materials?

In Lighting Japan 2016 (January 13-16) conference, Sumitomo Chemical and Merck revealed recently developed soluble OLED materials performance results.

 

The soluble OLED materials efficiency published in this conference reached ≥ 65% of UDC’s evaporation materials; particularly, Sumitomo Chemical’s red achieved ≥ 85%, and green reached ≥ 88% of UDC’s evaporation materials efficiency. Lifetime (LT 95) results were not as good as efficiency with red’s 25% and green’s approximately 40% (average).

 

Sumitomo Chemical and Merck both revealed that although in terms of efficiency the soluble materials almost caught up to evaporation materials, but lifetime requires further development.

 

Solution process is a method that allows for large area OLED panel production in RGB method using ≥ Gen8 manufacturing equipment. Key panel companies are actively carrying out research development, and the performance of soluble OLED material is considered the biggest issue. According to Solution Process OLED Report 2015, published by UBI Research, when solution process is applied the material cost can be approximately 40% reduced compared to the current evaporation process using large area OLED panel. The timing for the solution process application to mass production is expected to be decided depending on the development speed of soluble OLED materials.
