- Abstract
- A field emission device having a simple structure and capable of readily changing emission colors of light by adjusting emission intensity of red, green and blue light is provided. In the field emission device, current that flows into each cathode electrode block is adjusted according to a very low control pulse signal of 0 to 5 V with a predetermined voltage applied to an anode electrode and a gate electrode over time, so that emission intensities of red, green and blue are individually adjusted. Therefore, the current that flows into each cathode electrode block is adjusted in a simple manner using a control pulse signal of a low level without a separate pulse driving high-voltage power supply, so that emission intensities of red, green and blue can be arbitrarily adjusted and emission colors of the field emission device can be readily changed.
