Abstract
In a Q-tuple anode matrix vacuum fluorescent display (VFD), a plurality of selected pixels are turned on one by one to sequentially emit lights in accordance with a display signal. Each selected pixel is selected from Q anode segments to be turned on to emit lights by turning on a first and a second grid electrode positioned adjacent to each other. Each selected pixel is formed of Q/2 anode segments in total including R anode segments sequentially disposed from a position closest to the first grid electrode and facing the second grid electrode and (Q/2−R) anode segments sequentially disposed from a position closest to the second grid electrode and facing the first grid electrode, R being an integer ranging from 1 to (Q/2−1).
