Abstract
PURPOSE: To reduce the capacity of the refresh memory of a color CRT display device by providing a color designating memory to designate the color of information displayed in each segment when the display screen is divided into plural segments.
CONSTITUTION: As regards refresh memory 1, only one-picture components similar to the refresh memory of a white-and-black CRT are prepared. Color designating memory 2 to designate the color of information (characters, etc.,) displayed in each segment when the display screen is divided into plural segments (for example, 25 lines) is prepared besides this refresh memory 1. When write signal 3, address 4 and color designation signal 5 are sent from a CPU, information to designate colors of respective lines on the display screen divided into plural segments (25 lines) are stored in color designating memory 2. When a read signal is supplied to memory 2, characters, etc., are displayed with the color designated for every line according to memory contents.
