paint color control system with infrared photothermal conversion
In this paper, we describe our novel image display technology to control the paint color of everyday physical objects. RGB (Red-Green-Blue), an additive color mixture of light's three primary colors is used to create images in screens and display while CMYK (Cyan-Magenta-Yellow-Black), a subtractive color model is specialized to printing to papers. However, here we propose the system that uses CMYK color mode and digitally controls images by a chromogenic method of thermochromic inks. Due to the temperature sensitive property of these inks, this technology can digitally change painted colors of physical objects dynamically by changing temperatures. In order to achieve the high resolution and low-power color control system, infrared LED (Light Emitting Diode) was used as the device to control these inks with photothermal conversion. Through the development of the system and its some applications, we introduce our vision of "CM YK display".
