Abstract Submitted to the ; NANOTUBE'05 Conference:

The field emission display (FED) using carbon nanotube (CNT) array as emitters is expected as high quality display with low energy consumption. The difference of luminance between the neighboring pixels should be less than 5% to realize uniform emission all over the panel. In this paper, we clarified the required number of emission site for each pixel by using the statistical method. The distribution profile of emission current density from each multi-wall carbon nanotube is evaluated by emission profiler scanning Faraday cup with a 10 µm hole. The distribution is assumed to be Gaussian and the estimated average value divided by the estimated standard deviation is approximately 0.5. The required emission site number for each pixel is calculated to be approximately 3000. To reduce the required number of emission site, the standard deviation should be reduced by utilizing carbon nanotubes with more uniform diameter and length. This work was partially funded by the New Energy and Industrial Technology Development Organization.
