OLED technology has changed the display landscape remarkably. Now the next generation, QD‐OLED, is reaching the consumer TV market. At its heart, the quantum dot pixelized color convert (QD‐PCC) represents a fundamentally new component with materials and processes yet to be developed and scaled to reach the performance and reliability criteria for a commercially viable mass production. This communication will review critical hurdles encountered during the fabrication of such a color converter with a particular focus on the use of ink‐jet printing to deposit the optically active components. Smart material solutions will be reviewed explaining how they can help to overcome technical challenges and facilitate processing in an industrially viable environment ultimately enabling the cost‐effective commercialization of this promising new display technology
With the strong increase of mobile data‐communication needs, mobile devices become more important than ever. To be able to provide the users the best experience, display sizes will need to increase while portability needs to be maintained. Flexible, foldable and rollable displays are serving these emerging user needs. This challenges every layer in the display, requiring the display panel to become thinner and thinner while maintaining robustness and reliability. This paper will talk about highly reliable photo patternable interlayers in TFT stacks and touch sensor layers based on inorganic‐organic hybrid polymers. A novel solution, that improves process‐ability for flexible display devices. In addition, hybrid polymer‐based films provide good process durability, higher transparency, and higher environmental durability. Therefore, these new formulations are a key enabler for foldable and rollable OLED and e‐paper displays.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
