Abstract
Carbon nanotube emitters, prepared by screen printing, have demonstrated a great potential towards low‐cost, large‐area field emission displays. Carbon nanotube paste, essential to the screen printing technology, was formulated to exhibit low threshold electric fields as well as an emission uniformity over a large area. Two different types of triode structures, normal gate and undergate, have been investigated, leading us to the optimal structure designing. These carbon nanotube FEDs demonstrated color separation and high brightness over 300 cd/m2 at a video‐speed operation of moving images. Our recent developments are discussed in details.
