Individual data memorized in respective refresh memories contain each a display control bit adapted to determine whether or not the individual data are to be displayed on the screen. The data display control system reads out from the respective refresh memories a data information to be picture-displayed and only when the contents of a display control bit contained in the data information designate a display, it converts this data information into a video signal for a picture display. The contents of the display control bit are changeable for individual data.
