ABSTRACT:
A driving system and driving unit for driving luminous elements has a fast build-up speed from the application of voltage to the point of light emission, thereby allowing fast scanning, as well as the capacity for miniaturization of driving sources. The driving system for driving luminous elements includes a plurality of intersecting anode and cathode lines arranged in a matrix, the anode lines being one of scan lines and drive lines, and the cathode lines being the other of scan lines and drive lines; a plurality of luminous elements, each of the luminous elements being coupled to one of the scan lines and one of the drive lines at a point where the scan and drive lines intersect; and control circuitry for causing at least one of the luminous elements to emit light by executing scanning of at least one of the scan lines and, during a predetermined period of the scanning, by coupling a driving source to at least one of the drive lines in synchronism with the scanning, the control circuitry resetting the scan lines before switching to a subsequent scan line by coupling each of the scan lines to a same reset voltage potential.
