The field emission device includes: an anode substrate including an anode electrode formed on a surface thereof and a fluorescent layer formed on the anode electrode; a cathode substrate disposed opposite to and spaced apart from the anode substrate, and including at least one cathode electrode formed toward the anode substrate and a field emitter formed on each cathode electrode; and a gate substrate having one surface in contact with the cathode substrate, wherein the gate substrate include gate insulators surrounding the field emitters and having a plurality of openings exposing the field emitters, and a plurality of gate electrodes formed on the gate insulators around the openings and electrically isolated from one another. Thus, when the trajectories of the electron beams emitted from the emitters are rapidly changed over time by a voltage difference between the gate electrodes, an electron beam-scanned area can be expanded due to residual images and the electron beam can be more uniformly emitted due to an electron beam scattering effect and a linear beam spreading effect, resulting in improved emission uniformity of the fluorescent layer.

摘要： A discretely addressable large-area X-ray system is provided. The large-area X-ray system can output a uniform flux of X-rays over a large area using discrete addressing operation of transistors connected to cathodes of electron emitters. Thus, when applied to a medical device, the system can minimize damage inflicted upon the human body because it enables effective imaging of only a desired specific portion of the body. Furthermore, the large-area X-ray system can be simply implemented by current switching using transistors. Thus, the system can be very easily applied to other applications.

摘要： Provided is a field emission device (FED) capable of fine local dimming. In the FED, a cathode substrate is comprised of a plurality of cathode layers, and a plurality of interconnections are disposed on each of the cathode layers, so that fine local dimming is enabled using a plurality of cathode blocks without limiting the number of the cathode blocks. Also, since RC delays of the respective cathode blocks can be synchronized according to the design of the interconnections, current control signals can be simultaneously transmitted to the respective cathode blocks, thereby improving the characteristics of the FED.

摘要： Provided are methods of manufacturing carbon nanotube (CNT) paste, to which a nano-sized particle is added, and a CNT emitter with high reliability for a field emission display (FED). The method includes the steps of: (i) dispersing CNT powder in a solvent; (ii) adding an organic binder to the solution in which the CNT powder is dispersed; and (iii) performing a milling process to adjust viscosity of the dispersion solution to which the organic binder is added, wherein a nano-sized metal particle is added in step (i) or (iii). Accordingly, the nano-sized metal particle is added as a metal filler of the CNT paste, and thus a metal may be melted at a low temperature at which CNTs do not deteriorate. Thus, adhesion between the CNT paste and a cathode may be improved, and resistance between the cathode and the CNT or between CNTs may be reduced. Further, the CNT paste manufactured by the above method is employed in manufacturing the CNT emitter to thereby obtain uniform emission of electrons from the CNT emitter and increase electron emission sites, and thus the reliability of the CNT emitter may be further improved.
