Zusammenfassung:The present disclosure relates to a driving controlling device and a driving controlling method as well as an information processing system by which a display (backlight) with a high luminance and a high gradation can be implemented inexpensively and easily.Light emission of an LED is controlled by control of a current value of current for energizing the LED in addition to control of energization time for energizing the LED with current, to control the light emission luminance of the LED. The present disclosure can be applied to a large-sized video wall in which multiple display units having an HDR function are arranged in tile-like arrangement, an LED backlight of an LCD display, and so forth.
