Abstract
A method of driving a display apparatus with which unevenness of image is precluded and the time for display is shortened. A display apparatus for displaying an image by impressing a voltage on pixels by row electrodes and column electrodes disposed in a matrix, for example, a metal deposition type electrochemical display apparatus. A voltage not less than a threshold voltage Vis selectively impressed on predetermined pixels by superposing an address pulse voltage Vfor the row electrodes and an address voltage Vfor the column electrodes on each other to thereby perform address driving, and a data sustaining pulse voltage Vis impressed on the row electrodes immediately after the address pulse voltage V. The data sustaining pulse voltage Vsatisfies the condition of the following formula:V+V<V  (1).
