초록
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.
