    • 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.
    • 提供了具有简单结构并且能够通过调节红,绿和蓝光的发射强度来容易地改变发光颜色的场发射器件。 在场发射装置中,流过各阴极电极块的电流根据非常低的0〜5V的控制脉冲信号进行调整,并且随着时间推移施加到阳极电极和栅电极的规定电压,发光强度 红色,绿色和蓝色分别进行调整。 因此,流入各阴极电极块的电流使用低电平的控制脉冲信号以单独的脉冲驱动高压电源的方式进行调整,从而红色,绿色和蓝色的发光强度可以任意调整 可以容易地改变场致发射装置的调整和发射颜色。
