THE FIELD EMISSION DEVICE WITH FINE LOCAL DIMMING

摘要

A field emission device is provided to perform the minute local dimming according to a plurality of cathode blocks without the limit of number of the cathode blocks. A field emission device comprises the anode electrode and the fluorescent substance formed on the one side of the anode substrate(100); the cathode electrodes and the field emission emitter formed on the one side of the cathode substrate(200) facing the anode substrate; the field emission device which is possible for the minute local dimming including the gate electrode formed between the cathode substrate and the anode substrate. A plurality of cathode electrodes is blocked according to the sub pixel or the given area and comprises a plurality of cathode blocks. The cathode substrate is formed with multilayer.
