ABSTRACT:
In a display device arranging anode wires and cathode wires in a matrix shape, disposing light emitting elements at the intersections, scanning and driving the cathodes at specific time intervals, and driving the anode of a desired light emitting element in synchronism therewith, thereby selectively emitting the light emitting element, the display controller includes a setting unit for setting the discharge time for discharging the accumulated charge of the light emitting elements before light emitting of the light emitting elements, and operates and controls the anode controller and cathode controller for discharging the accumulated charge of the light emitting elements within the set discharge time, and also operates and controls the anode controller and cathode controller for emitting the light emitting elements after discharge control of the accumulated charge. In the display device having such configuration, supposing the luminance of the light emitting element when emitting light in no-charge or almost no-charge accumulated state to be Le, and the luminance by actual light emission to be Lp, they are in the relation of Lp≧0.9×Le, and further supposing the discharge time to satisfy this relation to be Tx, the discharge time Rt of actual discharge is determined to satisfy the relation of Tx≦Rt.
