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.

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.”

10월 14일 여의도 중소기업회관에서 개최된 ‘QLED와 Solution Process OLED 시장 진입 가능성 분석 세미나’에서 듀폰의 정성진 부장은 soluble OLED material에 대한 동향과 최신 개발 내용을 소개하는 시간을 가졌다.

정성진 부장은 현재 soluble OLED material과 공정기술은 완성 단계에 있으나 이를 결합하여 Solution Process를 어떻게 완성하는가에 대한 문제는 여전히 이슈로 남아 있으며, 이에 대해서 Material performance (T95>9k hr, CE>25 cd/A)와 Uniform printing (SRU>0.95), Contain (performance 90% of flood print), Conformal Drying(luminance aperture>95%)가 핵심 요소임을 언급하였다.

기존에 듀폰은 Surface Energy Modification을 이용하는 Nozzle Printing 방식으로 Solution process 연구개발을 진행했었다. 이 방식은 용액을 지속적으로 공급하기 양 조절이 쉽고 노즐이 막히지 않는 장점이 있었으나, 재료소모가 많고 panel 소재에 따른 제약이 있었다.

이러한 문제와 최근 커져가는 Ink Jet 시장으로 인해 듀폰은 Ink Jet Printing 방식으로 Bank를 형성한 후 유기물을 증착하는 방향으로 연구개발이 진행되고 있음을 밝히며, Ink Jet Material Performance를 공개하였다.

듀폰이 2016년 제 2회 OLED Korea Conference에서 발표한 자료와 비교해 볼 때, Red와 Green은 수명을 Blue는 효율을 중점적으로 개발한 것으로 보인다. Red의 수명은 약 6%, Green의 수명은 2배 향상되었으며, Blue의 효율은 약 10% 증가한 것으로 나타났다.

정성진 부장은 “점차 대형화 되는 display 시장에서 OLED로 시장 확대를 하기 위해서는 Solution Process를 채용이 필수적이며, 세트 업체에서 solution process로 2020년까지 US$ 1,000 이하의 55inch OLED TV를 양산할 수 있도록 soluble OLED 발광재료 개발에 집중할 것.” 이라 강조하였다.
