MATRIX VACUUM FLUORESCENT CHARACTER DISPLAY DEVICE

n this paper, the working principle and the structure of an X-Y cross matrix fluorescent character display panel is introduced. A close study of the property of this display panel is made. The relationship between its brightness and its operating voltages of each electrode and the modulation characteristics of the panel are discussed. On the basis of these characteristics, the driving scheme and the ways of designing driving circuits are presented. Moreover, an HBM-201 high brightness display device made up of this kind of display panel with brightness over 5000 cd/m2 is introduced. Under a filter the displayed characters can be clearly read in the sun-light.
