A display panel driving device that can obviate the need for constant current
driving
circuits in an anode driver circuit, in which a light emission column electrode
lines is opened in a light emission period during scanning of each line of a display
panel, and parasitic capacitors of light emitting elements are used to allow leak
current from the combined parasitic capacitors of the non-scanned elements to the
scanned elements to serve as the light emission current of the scanned elements.
