Claims

[Scope of utility model registration request]

An image is displayed on a display panel section composed of LEDs that emit red and green light based on the red, green, and blue color data of the digital RGB signal input from the display data input means, and characters are displayed on the background image. A display device that inputs the superimposed image as blue data from a display data input means when overlapping images such as the above, and data that converts the blue data input from the display data input means into data that can be distinguished from the background color. A display device comprising a converter.
