Various solutions for high resolution OLED implementation were released at iMiD 2017 held in COEX from October 18th to 19th. As the resolution of small and mid-sized OLEDs, which are currently being commercialized, is staying at the QHD level, the solutions released at this time have attracted a great deal of attention from display members.
지난 10월 18일부터 19일까지 코엑스에서 열린 iMiD 2017에서 고해상도 OLED 구현을 위한 다양한 solution들이 공개 됐다. 현재 상용화 되고 있는 중소형 OLED의 해상도가 QHD급에서 머물고 있는 만큼 이번에 공개 된 solution들은 디스플레이 관계자들에게 큰 주목을 받았다.
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 […]
28일 부산 BEXCO에서 개최된 iMiD 2017에서 AP Systems는 USPL(ultra-short pulse laser)로 1000ppi FMM개발에 성공했다고 발표하였다.
FMM은 화소와 RGB 유기물을 증착하는 역할을 하기 때문에 FMM은 OLED의 해상도와 수율을 결정짓는 요소로서 작용된다. 현재 FMM은 주로 전주(etching) 방식으로 제작되고 있다. 이 방식은 미세 패턴의 정밀도와 두께, 무게에 의한 섀도우 현상이 발생하는 문제가 있어, 이를 해결하기 위해 laser 가공, 전해주조(electro-forming)등 다양한 FMM 제조 공정이 개발되고 있다.
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.
