Multiplex anode matrix vacuum fluorescent display and the driving device therefor

A multiplex anode matrix fluorescent display including a plurality of anode electrodes and a multiple number of grid electrodes arranged in a form of a matrix, the grid electrodes being arranged in such a way that k column of the anode electrodes corresponds to each grid electrode, k being an even positive integer, and the anode electrodes and the grid electrodes being divided into a number of regions in the direction of row, and the plurality of anode wirings in a form of the multiplex anode matrix is formed on each of the regions,

• characterized in that the display comprises a grid driver and an anode driver, wherein the grid driver simultaneously applies a driving voltage to two columns of adjacent grid electrodes in each of the regions by scanning grid electrode by grid electrode in the direction of row, the anode driver displays a plurality columns of the anode electrodes located at the two adjacent grid electrodes, to which the driving voltage is applied, in response to a displaying data, and, at the border line between each of the regions, when an end of a region of the grid electrode and an end of a region of the anode electrode are simultaneously driven, the grid driver and the anode driver make the scan cycles of the grid driving pulse in each region synchronous to simultaneously drive other end of the region of the grid electrode and other end of the anode electrode.
