Abstract:
1. A light-emitting cell, comprising: a light-emitting material which can emit light in response to a collision of an electron beam; an electron-emitting unit having a carbon nanotube as an electron source for releasing said electron beam and emitting said electron beam to ram against said light-emitting material; and a gate disposed above said carbon nanotube for controlling said electron beam emitting from said carbon nanotube whether to pass through said gate to ram against said light-emitting material at a specific address; wherein said gate comprises a network conductor including a first metal layer of longitudinal conductors for determining an x-coordinate of said address, a second metal layer of latitudinal conductors for determining a y-coordinate of said address, and an extracting electrode placed between said carbon nanotube and said first metal layer for extracting said electron beam from said carbon nanotube, and wherein said gate further comprises a second insulating layer placed between said second metal layer and said first metal layer.
