ABSTRACT:
A display control system can implement a gray-scale display of an image composed of a plurality of display dots on a display screen. A plurality of luminance data each representing an intensity level of a corresponding one of the plurality of display dots are first generated. Each luminance data is then converted into a pulse signal whose pulse number corresponds to an intensity level of the corresponding display dot represented by the luminance data. And, each display dot on the display screen is activated in accordance with a corresponding one of the thus produced pulse signals. To eliminate flicker of the display dots, the display dots on the display screen are grouped into a plurality of display sections each composed of a predetermined number of adjacent display dots, and if the display dots in one display section are equal in intensity level, these display dots are activated by the pulse signals which are equal in pulse-number but different in phase.
