Abstract:
A method for driving a display apparatus with capacitive light-emitting devices including a plurality of capacitive light-emitting devices located at a plurality of intersections of drive lines and scan lines and respectively electrically connected between said scan lines and said drive lines, scan switches for connecting said scan lines to one of a first potential and a second potential different from each other when activated, drive switches for connecting said drive lines to either one of said first or second potential or a drive source when activated, and emission control means for controlling said drive switches and said scan switches, whereby said drive switches are activated so as to selectively connect said drive lines to said drive source to allow selected capacitive light-emitting devices to emit light in synchronism with scan timings at which said scan switches connect said scan lines to a lower one of said first and said second potentials, comprising the steps of:inserting a reset period between each of scan periods;selecting unconnected drive lines among all of said drive lines which are not connected to said drive source in a present scan period; andconnecting all of said scan lines to the same reset potential, connecting the selected unconnected drive lines to the ground potential and connecting the other drive lines to said reset potential in said reset period.
