Abstract:
1. A method of driving a display apparatus for displaying an image by deposition and dissolution of a metal, the deposition and dissolution being controlled at each pixel by impressing a voltage on the pixels by row electrodes and column electrodes which are disposed in a matrix, wherein a voltage equal to or more than a threshold voltage Vth is selectively impressed on predetermined pixels by superposing an address pulse voltage Vaddress-row, for said row electrodes and an address voltage Vaddress-col, for said column electrodes on each other in order to cause deposition of the metal to begin, the voltage equal to or more than the threshold being only momentarily applied to selected pixels to ensure that deposition of the metal begins only at certain selected pixels without exhausting an available amount of metal for deposition during application of the voltage equal to or more than the threshold, and a data sustaining pulse voltage Vsus satisfying the relationship of the following formula (1): is thereafter impressed on said row electrodes immediately after said address pulse voltage Vaddress-row, in order to cause additional deposition of the metal to continue.
