Abstract

PURPOSE: To realize a character display control system where the hardware amount is reduced considerably in the display system which displays characters, etc., on plural display devices simultaneously.
CONSTITUTION: Display memories 5 and 6 are provided correspondingly to display devices and store display data which is displayed on display devices. Character generator 9 is subjected to access by using data read from one of display memories as the address, and stores dot pattern information of displayed characters, etc. Display control signal circuit 3 generates display control signals, and phase difference circuit 21 generates display control signals different in pahse by time t/n in display time t for one character. Then, dot pattern information read out from character generator 9 and the display control signal from phase difference circuit 21 are synthesized and supplied to a corresponding display device, and information is displayed on respective display devices with phase difference t/n.
