Abstract
The electron emission characteristics, current emission stability, and uniformity of screen-printed carbon nanotube were enhanced by introducing a novel dual-particle-containing multicomponent-blending carbon nanotube cathode via the comprehensive combination of baking in the air and sintering in the inert gas atmosphere. The dual-particle-containing multicomponent-blending carbon nanotube cathode’s design and manufacturing improvements ensured its steeper emission curve variation amplitude, larger maximum emission current, better electron emission current of 806.7 μA was only 2.56 V/μm. When it was increased from 2.78 to 2.91 V/μm, the enhancing current emission amplitude of the proposed cathode was increased by 600.7 μA versus 324.1 μA of the conventional non-blending carbon nanotube cathode. The maximum emission current of the proposed cathode was 3762.5 μA. After the vacant static state of 72 h, the measured emission current had no obvious attenuation, and the fluctuation rate of emission current did not exceed 5%. The backlight unit with dual-particle-containing multicomponent-blending carbon nanotube cathode was sealed, and the obtained emission image had high luminescence brightness and uniformity.
