Information Kansei Engineering Lab
Machine-translated · View original
A lab studying displays that control the texture of digital information.
AboutAbout the lab
Creating the world with gentle light.
The Information Kansei Engineering Lab conducts research with the goal of building display technology that controls the texture of digital information.
It clarifies how people feel and receive information, that is, the relationship between human sensibility (kansei) and information.
It aims for a state in which digital information shown on a display looks like a real object.
As the fusion of the real and digital worlds becomes increasingly important, the lab believes that building information systems that place little burden on people and are gentle to them is essential for realizing a sustainable society.
Key terms
- Polarized light
- Light whose direction of vibration is aligned. It is obtained by passing light through a polarizer
- Liquid crystal
- A substance with properties between those of a solid and a liquid. Changing the orientation of its molecules controls how light passes through it
- Electronic holography
- A technology that reproduces the wavefront of light coming from an object to display an image in space

ResearchResearch themes
The lab researches how to create human-friendly displays by finely controlling light with liquid crystals and other materials. Its research overview summarizes results in developing wide-viewing-angle liquid crystal displays, reflective displays, and devices for electronic holography.
*Illustrative imageLarge-screen, wide-viewing-angle displays
The lab built a theory for rigorously analyzing polarized light and developed a wide-viewing-angle polarizer whose polarization axes remain orthogonal for light incident from any direction. This has realized ultra-wide-viewing-angle liquid crystal displays whose appearance does not depend on viewing angle.
*Illustrative imageDeveloping functional light-control films
By biaxially stretching polymer films to control the refractive index in the thickness direction and giving them biaxial optical anisotropy, the lab has established technology to control polarized light three-dimensionally.
*Illustrative imageUltra-low-power reflective displays
The lab devised the basic structure of a reflective full-color liquid crystal display that shows images using ambient light, and demonstrated its effectiveness. It is easy on the eyes like printed paper, and its power consumption is 30 μW, less than one hundredth that of conventional liquid crystal displays that require a backlight.
*Illustrative imageFine molecular alignment and electronic holography
Toward electronic holography, which reproduces the wavefront from an object to display an image in space, the lab developed a liquid crystal spatial phase modulator with a 1 μm pixel pitch. It places partition walls 200 nm wide between pixels to precisely control molecular alignment in tiny regions.
