/in , , , /by

At the 28th FINETECH JAPAN held in Tokyo, Japan from December 5 to 7, 2018, JDI and JOLED announced that they would intensify their cooperation in order to target the middle-sized OLED market.

JDI announced that it will actively promote JOLED’s solution process OLED to medium-sized OLED markets such as industrial display markets or automotive display markets through its own design know-how, production infrastructure, and sales channels,.

In particular, JDI announced that it will provide new value to next-generation automotive fields along with JOLED such as support for safety such as electronic mirrors and displays for A/B pillars, new interface functions, movie appreciation using 4-8K displays, and the displays that are harmonized with interior design such as curved surfaces and big screens.

JDI and JOLED also shared booths for exhibition. JOLED introduced 21.6-inch FHD OLED monitors for e-sports and medical applications. In addition, it introduced a number of medium-sized OLEDs such as 12.3-inch HD OLED for automobiles, 12.2-inch FHD flexible OLED, 27-inch 4K OLED for home interior, and 21.6-inch 4K flexible OLED with cylindrical form. It also showcased large OLEDs such as 54.6 inch 4K OLED.

On the other hand, JOLED announced in July, 2018 that it would open its Nomi office for mass production of solution process OLED. Based on 5.5 generation glass substrates, Nomi has production capacity of 20,000 glass substrates per month and plans to mass-produce in 2020.

머크, SID 2017에서 디스플레이를 위한 미래지향적인 소재 공개

/in /by

머크는 21일 개최되는 SID Display Week 2017에서 새로운 디스플레이 기술과 향후 진행될 프로젝트를 공개할 예정이라 밝혔다.

이와 더불어 머크는 ‘The Perfect Pixel – Advanced materials for display and beyond’를 주제로 광범위한 제품 및 서비스 포트폴리오를 전시할 예정이다.

머크의 디스플레이 재료사업부 총괄 책임자인 Michael Heckmeier는 “우리는 고객과의 긴밀한 관계를 통해, 디스플레이의 기술뿐만 아니라 품질과 신뢰성, 서비스를 점차 향상시키고 있다”고 말했다.

또한, Michael Heckmeier 총괄 책임자는 “지속적인 개발을 통해 선도업체로의 입지를 더욱 확고히 할 것”이며, “환경 친화적이고 보다 더 효율적인 생산 프로세스를 개발함으로써 최종 소비자에게 보다 나은 경험을 제공 할 것”이라며 앞으로의 계획을 밝혔다.
이를 위해 머크는 “디자인의 제약이 없거나, 유연함, 또는 색재현성, 명암비, 에너지 효율이 높은 디스플레이 외에도 액정 윈도우(liquid crystal window, LCW) 모듈과 같은 혁신 제품에 초점을 맞출 수 있다”고 덧붙였다.

머크는 SID 컨퍼런스에서 ink-jet printing용 soluble 재료 개발 현황에 대해 발표할 예정이다.

머크에 따르면 ink-jet printing으로 만든 red와 green 층은 진공 증착 기술로 만든 것과 유사한 효율을 보이고 있다. Ink-jet printing 방식은 Gen8이상 원장에서 RGB pixel 구조의 대면적 OLED panel 구현이 가능하고, 재료사용효율이 높고 단순한 layer로 개발되고 있어 양산 성공 시 원가절감이 가능하다는 장점이 있기 때문에 이에 대한 귀추가 주목된다.

한편, 머크는 지난 OLED Korea Conference에서 soluble 재료에 대해, “Red는 16.4%의 발광효율과 LT95 2,000h의 수명을, green은 18.7%의 발광효율과 LT95 8,000h의 수명을, blue는 7.5%의 발광효율과 LT95 500h의 수명(1,000cd/m2 기준)을 보이고 있다” 며, “11% 이상의 발광 효율을 갖는 형광 blue dopant와 밝기가 20cd/A 수준으로 향상 된 인광 deep red dopant, 밝기가 80cd/A 수준으로 향상 되고 roll off를 갖는 인광 green dopant를 개발하는 것”이 목표라 말한 바 있다.

 

Merck, introducing future-oriented material for the display in SID 2017

Merck said new display technologies and upcoming projects will be presented at SID Display Week 2017

In addition, Merck will exhibit a broad portfolio of products and services under the theme of ‘The Perfect Pixel – Advanced materials for display and beyond’.

“We are gradually improving not only display technologies but also quality, reliability and service through our close relationship with our clients,” said Michael Heckmeier, General Manager of Display Materials Business at Merck.

He also revealed the future plan, saying “continuous development will further solidify our market position as a leading company. We will provide a better product experience for end-user by developing eco-friendly and efficient production processes. ”

To this end, Merck added, “apart from unrestricted designing, flexibility, or color gamut, contrast and energy efficiency, we can focus on innovative products such as liquid crystal window (LCW) module.”

At the SID conference, Merck will present the development status of soluble materials for ink-jet printing.

According to Merck, red and green layers made with ink-jet printing have shown efficiency similar to those made with vacuum deposition technology.
Ink-jet printing approach can realize a large-sized OLED panel bigger than Gen8 with RGB pixel structure; it is developed as a simple layer with high material utilization efficiency, which is cost effective in mass production.

At the OLED Korea Conference, Merck said, “Red shows a 16.4% luminescence efficiency and LT95 2,000h long life expectancy; for green 18.7% and LT95 8,000h; blue 7.5% LT95 500h (based on 1,000cd/m2). He once said that the corporate goal is to develop a fluorescent blue dopant with  luminous efficiency higher than 11%, a phosphorescent deep red dopant improving from 20 cd/A brightness to 80 cd/A and phosphorescent green dopant with improved roll off.”

[Analyst Column] Solution Process OLED to be released from 2016

/in , /by

The possibility to mass produce AMOLED panel in RGB structure by solution process was confirmed after the appearance of the solution process 4K OLED TV by Panasonic in 2013 and as AUO unveils the 65-inch FHD AMOLED panel at SID 2104 which uses hybrid process of employing inkjet printing method and deposition method simultaneously.

According to the Solution Process OLED Report 2014 issued by the UBI Research on the 26th, it is expected to release AMOLED panel by solution process by 2016 considering the stages of the process equipment and materials developments up to now.

The solution process is producing OLED by printing the material of liquid condition. The efficiency of the material usage in case of the existing RGB deposition method is as low as about 10%, requiring complicated processes and it is difficult to apply to the large area substrate.

The efficiency is theoretically 100% for the solution process, resulting cost saving and even the process of RGB method without cutting the substrate at the 8thgeneration line is possible.

However, there are remaining issues to be resolved as the material property is low compared to the deposition material and it is unavailable to produce high resolution panel.

The personnel from the UBI Research reported that the analysis shows the probability to produce from 8.4-inch FHD panel to 8K high resolution panel over 30 inches in RGB method for it is possible to print up to 300ppi as the printing error reduces. The present OLED panel for tablet PC has a resolution of about 262ppi because it was produced in PenTile method. Now, the large area panel as well as the RGB OLED panel for tablet PC are mass produces as a result of the solution process allowing up to 300ppi.

Also the property of emitting material was improved. Assumed from the analysis of properties announced so far, the efficiencies of red and green among other emitting materials for the solution process are developed close to the deposition material. Especially for the green, the small molecular material for the solution process appears to be more efficient than the polymer material for the deposition.

“Considering the development level of the material and process equipment for the solution process, the AMOLED panel produced in the solution process will be released actively from 2016, and in view of the current line conditions of panel companies, the investment ability, and technical situations, it is expected to produce the AMOLED panel for the tablet PC at first” said the personnel from the UBI Research.

In addition, the AMOLED panel market for the solution process will be the size of $380 million with the average annual growth rate of 141% by 2017 as the material for the solution process is anticipated to have the full competitiveness by the same year.
