  • Display device
    Publication number: 20060132050
    Abstract: A display device uses electron accelerating layers in conjunction with electrodes at different voltages to emit electron beams with energy levels sufficient to excite a gas, which emits ultraviolet rays that in turn excite a light emitting layer to emit visible light. The use of electron accelerating layers makes it possible to excite the gas using a lower driving voltage and achieve improved luminous efficiency.
