Abstract:
A method of driving a luminous display in a simple matrix drive system in which luminous elements are connected at the intersections of a plurality of anode lines and a plurality of cathode lines which are arranged in matrix form, the cathode lines or the anode lines are employed as scanning lines, while the other are employed as drive lines, and while the scanning lines are scanned with a predetermined period, in synchronization with the scanning operation drive sources are connected to desired lines to cause luminous elements to emit lights which are connected at the intersections of the scanning lines and the drive lines, said method comprising:scanning one scanning line; and during a period between the scanning of the one scanning line and the scanning of a succeeding scanning line, applying a first offset voltage to a first drive line of the drive lines to charge a first luminous element of the luminous elements and applying a second offset voltage to a second drive line of the drive lines to charge a second luminous element of the luminous elements, wherein the first offset voltage is different than the second offset voltage.
