Development of CMYK Color Display: Display by Chromogenic Effect to Control Painted Color on Paper

Hiroki Yamada, Kunihiro Nishimura, Tomohiro Tanikawa, Michitaka Hirose


In this paper, we describe our novel image display technology to control painted colors on paper. RGB (Red-Green-Blue), an additive color mixture of light's three primary colors is used to render digital images and images with CMYK (Cyan-Magenta-Yellow-Black), a subtractive color model is specialized to printing or
painting to papers. However, here we propose the system that uses CMYK color model and digitally controls colors of images by a
chromogenic method of external irritation-sensitive inks. Due to the special property of the ink, this technology can
digitally change painted colors of everyday physical objects dynamically.
In order to achieve the color control system with high-resolution, low-power, multi-color, and high update rate, peltier device and
infrared LED (Light Emitting Diode) were used to control thermochromic inks. Through the development of two prototypes, we introduce our vision of “CMYK display”.
