Abstract
PURPOSE: To make the continuity of a graphic pattern good by switching the memory read to a character mode and a graphic mode.
CONSTITUTION: In case of a character mode, switches 283 and 289 are connected to the lower side to blanking signal gs of line interval four-scanning components through scanning line counter 28d and inverter 280. Then, blanking signal js is obtained through counter 28f for the number of lines and FF288. In case of a graphic mode, switches 283 and 289 are switched and controlled not to generate inter- line blanking signals. A continuous and smooth pattern can be displayed because no inter-line blanking signal is generated in the graphic mode.
