Abstract
A super high resolution cold cathode fluorescent display (CFD) utilizes an anode with cathodoluminescent means, a cathode with field emission cathode group array, a glass like spacer plate structure providing an array of funnel-shaped channels. Each channel has a narrow aperture which serves as a pin hole for passage of electrons between the cathodes and anode. The display uses a circuit for generating a strong electric field between the anode and cathode in the array of channels to take advantage of the pin hole imaging effect to produce high resolution, full color images for the display.
