PURPOSE: To freely design anode patterns without being restricted by the shape of grids. ;CONSTITUTION: Multiple rectangular grids 1G-6G having the same shape are arranged at a fine interval. Single-anode patterns S1-S4 face each pair of adjacent grids of 2-6 grids respectively. Other single-anode patterns Dig1-Dig6 face individual grids respectively. The anodes Dig1-Dig6 are driven for individual grids, pairs of grids facing the anodes S1-S4 are selected respectively, and the display signal is applied to the anode facing the pair at this time. Grid parts can be used in common, and the grids can cope with any anode pattern.;COPYRIGHT: (C)1994,JPO
