The present disclosure relates to a drive control device, a drive control method, an information processing system, and an information processing method for an information processing system capable of suppressing generation of an abnormal sound in a passive-matrix driven LED display device. A blanking interval between frames is made shorter than a time set according to a display standard, and the blanking interval ends before a ripple voltage rises. Accordingly, suppressing a rise in the ripple voltage caused by a reduction in current flow through LEDs during the blanking interval lowers a voltage applied to an MLCC, and suppressing distortion of a substrate resulting from expansion or contraction of the MLCC caused by the voltage application suppresses generation of an abnormal sound. This disclosure is applicable to a passive-matrix driven LED display device.
