Abstract

PURPOSE: To ensure a color display without lowering the display efficiency of the display screen by providing a color buffer in order to prevent the color information from occupying the display area of the CRT screen as well as to ensure setting of the reading time of the color information between the lines.
CONSTITUTION: Processor 13 changes the supplied character code information to the character dot pattern information through pattern memory 12 and then trasmits the dot pattern information to refresh memory REM11 along with the color information. The color information is memorized in the first scanning line of each line in RFM11, and the dot pattern information is memorized in the second to 32nd scanning lines of each line respectively. Under these conditions, the color information corresponding to all the first scanning regiouns of the first line of RFM are memorized in sequence in color buffer 15 based on the display scan of CRT3. After this, the character dot pattern information of RFM11 is combined via gate 6 to the color information of color buffer 15 corresponding to the dot pattern information to be displayed on CRT3. This action is repeated for the second and subsequent lines
