Japan and the mainland in order to reduce the size of organic light emitting diode (OLED) production cost, accelerate the development pace of recent, a South Korean panel factory quickly launched samples, which is for the production of 10.5 generation liquid crystal display (LCD) of large size OLED more price competitive strategy by using.
According to the Korean media reported ET News, JOLED TCL, held in Japan and South Korea in Seoul 2018 OLED Korea forum, open inkjet printing technology development status, to attack the next generation of manufacturing technology of large size OLED to enter the market, although the technology has not yet reached the formal production stage, but the performance of ink-jet printing equipment and materials have been upgraded to to some extent, the estimated 1~2 years to ensure production technology.
JOLED revealed that it has recently developed the inkjet printing process display that can display 300ppi above resolution on the 8 generation of substrates. In 2017, the 21.6 inch 4K OLED monitor sample was developed on inkjet printing process on the 4.5 generation substrate, and samples were supplied to ASUS. JOLED expects to display 300ppi resolution on the 8 generation of substrates, producing inkjet printing process and OLED panel for high quality tablet computers. The 21.6 inch 4K OLED monitor panel previously launched can achieve 204ppi resolution.
JOLED originally decided to mass production of 21.6 inch monitor, for investment in equipment, but nearly due to funding problems, looking for foreign investment, the production situation is still uncertain. The 200ppi resolution is suitable for the 20 inch level monitor or larger size TV panel. If JOLED achieves 300ppi resolution, it can also achieve high quality in the 10 inch panel. JOLED has a low possibility of investing in measuring production equipment at present, but it has its own technology. If it begins to produce, it will have impact.
TCL, the establishment of R & D open platform inkjet printing Guangdong Juhua printing and display technology, the day before the inkjet printing technology developed 31 inch 4K OLED panel, the panel subsidiary Huaxing power is also involved in research and development, and in the 4.5 generation substrate is half the size of production line production. The goal of TCL is to ensure the 11 generation of substrate inkjet printing technology before 2019. In April, we will open the international specification technology (ICDT) specification in Guangzhou, China, together with Huaxing photoelectric, Tianma, China Electric panda and university institutions.
Panel (BOE), the leading BOE also perform large-scale investment in this field, reportedly considering BOE LG display WOLED (White OLED) technology or inkjet printing technology, the production of large size OLED cross market.
Korean panel factory is also developing ink-jet printing technology, LG display (LG Display) and Samsung (Samsung Display) are on display inside the construction of experimental production line production samples, but never revealed to the outside world or public information related to sample. LG display by Japan's Tokyo electric power generation 8 inkjet printing equipment construction experimental production line, Samsung display using inkjet printing equipment research and development technology of American Kateeva and Semes.
The Korean industry is worried that South Korea is going beyond the competitive market in the inkjet printing market. The mainland is a large-size OLED market, which is very likely to span WOLED technology and directly use inkjet printing technology. Samsung said earlier development of large size OLED business, Samsung restart large size display technology development, LG display also consider the introduction of inkjet printing technology in the 10.5 generation of the production process, however, the first to enter the market probably will.
