Active-matrix and flexible liquid-crystal displays with carbon-nanotube pixel electrodes

The necessary processes to use random carbon-nanotube networks as transparent conductors in twisted-nematic liquid-crystal displays have been developed, replacing indium tin oxide. Because the nanotubes are deposited vacuum-free from suspension, the potential advantages are lower costs for material, equipment, and production. Nanotube networks are also much better suited for flexible displays than the commonly used metal oxides. With the developed processes, the world's first full-color active-matrix LCDs as well as directly addressed flexible displays on plastic substrates with carbon-nanotube pixel electrodes, have been realized.
