Abstract

This paper presents a plasma display device (PDD) based on laser-induced graphene nanoribbons (LIGNs), which were directly fabricated on polyimide sheets. Superior field electron emission (FEE) characteristics, viz. a low turn-on field of 0.44 V/μm and a large field enhancement factor of 4578, were achieved for the LIGNs. Utilizing LIGNs as a cathode in a PDD showed excellent plasma illumination characteristics with a prolonged plasma lifetime stability. Moreover, the LIGN cathodes were directly laser-patternable. Such superior plasma illumination performance of LIGN-based PDDs has the potential to make a significant impact on display technology.

Summary

Introduction

Displays are an essential interface in machine-based communication. There have been major developments in display technology, with the potential to enable television, handheld computers, and mobile phones to be more functional and user-friendly [1–4]. This confirms that LIGNs have a high FEE current stability, which is a beneficial characteristic for device applications.
