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; and drive switches for selectively connecting said drive lines to at least one of said first and second potentials, for selectively connecting said drive lines to a drive source, and for selectively placing said drive lines in a floating state, wherein 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 of said scan switcheswherein the method comprises:inserting a reset period between scan periods during which said scan lines are scanned; selecting selected drive lines, from among all of said drive lines, that are not connected to said drive source in a previous scan period and a present scan period; connecting all of said scan lines to a reset potential during said reset period; opening said selected drive lines to place said selected drive lines in said floating state during said reset period; and connecting said drive lines other than said selected drive lines to said reset potential during said reset period.
