A nanotube-based field-emission flat panel display

TLDR

Further improvement of this technology may lead to easy‑to‑make and inexpensive flat panel displays. A matrix addressable diode flat panel display has been fabricated using a carbon nanotube–epoxy composite as the electron emission source. The prototype shows uniform field‑emission across pixels, well‑lit operation at ±150 V, and reliable on/off control via a half‑voltage off‑pixel method.

Abstract

A matrix addressable diode flat panel display has been fabricated using a carbon nanotube–epoxy composite as the electron emission source. Field-emission uniformity has been confirmed by measuring the I–V curves of pixels across the panel. This prototype display demonstrates well-lit pixels under ±150 V biasing signals. The “on” and “off” of the pixels are well controlled by the half voltage “off-pixel” method. Further improvement of this technology may lead to easy-to-make and inexpensive flat panel displays.
