Claims

[Scope of utility model registration request]

at least two colors, each with a specific display color;
In a display device equipped with an image compositing display function that displays display images of files superimposed on each other, there is provided an overlap detection circuit that detects an overlap of the same color signals of display images in each of the above files, and this overlap detection circuit. a color signal conversion circuit that converts the same color signal detected by the color signal into another color signal specific to the color in which the overlap has occurred; 2. A display color conversion circuit comprising: a gate circuit for selectively outputting a color signal in place of the color signal.
