| 摘要 |
<p>The present invention relates to a symmetric quadrupole structured field emission display without spacer whose center of symmetry is the bus electrode, comprising the upper and under substrates, wherein comb-like dielectric layer with lateral connection belts and a number of longitudinal working belts and longitudinal anodes are arranged on the upper substrate, bus electrodes are arranged longitudinally along the center on each anode, where on top, there are longitudinal alternating phosphor layer and dielectric layer for isolation on anode, gate electrodes are arranged on both sides of each longitudinal work belts, with the bus electrode as symmetry center, forming interdigital gate electrodes, there are horizontal cathode electrodes and longitudinal auxiliary electrodes on the under substrate, resistor layer for current limiting and dielectric layer for cathode protection are arranged alternating horizontally on each cathode electrode, each intersect of the auxiliary electrode and cathode is isolated by the dielectric layer for cathode protection, dielectric layer is also arranged between the upper and under substrates. The field emission display presented in this invention is novel, but also simple in fabrication, moreover, it having image uniformity, low modulation voltage, the electron emission is stable and reliable.</p> |
