Transparent display is currently an interesting topic in the display technologies for mobile device, monitor, shopping window or smart window application. This paper described the large area (14 inch) transparent electrowetting display (EWD) by using twolayer hydrophilic rib structure and manufacturing process is proposed as well. This work included two parts: structure and process development of large area transparent electrowetting display and the implementation of two-layer hydrophilic rib structure and plasma treatment in the manufacturing process for electrowetting display. The two-layer structure material and plasma treatment is implemented to modify the manufacturing process and improve the panel performance. The development of this study realized the concept of transparent electrowetting display with large size display area.
Transparent Electrowetting display (EWD) has been considered as one of the promising technologies for transparent display application. The performance and reliability of transparentEWD were studied and improved in this research. The surface modified of rib structure was implemented to inhibit oil overflow and patternable hydrophobic layer was also developed to deal with oil non-recovery issue.
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.
