<p>PROBLEM TO BE SOLVED: To provide a method of driving a matrix electron-source, capable of obtaining an image, in which there is little blur, when driving the matrix electron-source used in an image display device. SOLUTION: A driving circuit driving a matrix electron-source controls potentials of row selection electrodes X1, X2, X3, and X4, and potentials of column selection electrodes Y1, Y2, Y3, and Y4 as shown in Fig. 1 (a) to (h). Assuming that the potential of a surface electrode (row selection electrode) is VXH when it is selected, but VXL when it is not selected, and the potential of a lower electrode (column selection electrode) is VYH when it is not selected, but VYL when it is selected, the potentials VXH, VXL, VYH, and VYL are set so that VXH>VXL and VYH>VYL. The driving circuit controls potentials of the column selection electrodes Y1 to Y4 so that they become VYL for a certain time in order of line, and controls potentials of the row selection electrodes X1 to X4 so that potentials of only row selection electrodes corresponding to sub-pixels to be lit become VXH.</p> |
