Paper Abstract

A 2.3-inch, 150 X 90 pixels, high brightness, high luminance efficiency, and long life of field emission display (FED) with very low power consumption was reported. The spacing between the anode plate and the field emitter plate was 3 mm. The anode plate, coated with Y2O2S:Tb phosphor, was processed by a screen printer. A high voltage, varied from 1KV to 9KV, was applied to the anode. It was observed that the luminance efficiency increased as a function of the applied voltage to anode. Moreover, the aluminum film was coated on phosphors, which made the luminance efficiency increase more than 1.7 times, compared to no Al film,when the anode was applied to 7KV. It was demonstrated that the luminance efficiency of phosphor plate is more than 15 lm/W in our FED panel. As well, the low parasitic capacitance design of the field-emitter plate makes the field emission display very power-efficient and with very low power consumption.
