Inkjet Printing Display Technology Report

Report Summary

Inkjet printing (IJP) technology is seen as an alternative choice to WOLED in large-size premium TV applications as well as potentially a primary option for medium sized displays. In recent years, panel makers, like Samsung Display, LG Display, AUO, BOE, China Star and JOLED, have put a lot of energy and investment into this technology. This technology is maturing every day, and it is likely to move into actual production in the near future. In 2021, China Star not only invested in and began collaborating with JOLED, but also revealed its T8 Gen 8.5 inkjet OLED mass production line plan in Guangzhou, Guangdong, China. Although the timing of T8 remains unclear at the moment, it can still be seen as an essential step for inkjet technology entering actual production. With this report, DSCC provides a comprehensive analysis of this technology and discusses machine setup, technology details, the current supply chain, panel makers’ plans and product cost in each of the different types of products. Potentials, bottlenecks and feasible solutions of this technology are also reviewed in detail.
