する合成回路を備えた表示装置。 A microcomputer that uses digital processing to control the display of figures, the fill brightness of the upper and lower background areas, and the border position; a frame memory that holds the brightness signals of the figure display by this microcomputer; A register that holds the brightness of the two background areas and the position of the boundary line, respectively. Based on the values of the above registers, a display deflection signal X and a deflection signal Y are generated in order to fill in the two background areas at the top and bottom of the display screen. A scan signal generation circuit, a comparator that compares the deflection signal Y with the position of the boundary line set in the register by the microcomputer, and a control signal of this comparator to generate the luminance signals of the two upper and lower background areas respectively set in the register. A display device comprising: a selector for selecting and outputting; and a synthesis circuit for synthesizing a luminance signal of a figure output from the frame memory and a luminance signal of a background area output from the selector.
