Abstract:
The purpose of this paper is to investigate the applicability of field emission (FE) cathode arrays for a cathodoluminescent display device. We proposed a tetrode structure which has a grid inserted between the Mo emitter FE cathode arrays and the anode. The focusing properties of electron beams were measured using the Y 2 SiO 5 :Tb phosphor, and a green emission of about 66,700 cd/m 2 was achieved at the anode current of about 90 mA/cm 2 and the anode voltage of 8 kV in a vacuum chamber kept at 1×10 -9 Torr, in which 14,700 Spindt-type cathode tips were used. The experimental results showed that the dispersion of electron beams can be controlled to a considerable extent by the shape, distance and voltage of the grid. An effect of SO 2 gas on the emission property of FE cathode arrays was measured, too.
