Single-component white-color photoluminescence from liquid crystal polymers: Color tuning by a combination of luminescence thermo- and mechanochromism

Tuning the correlated color temperature of white LED with a guest-host liquid crystal.

We demonstrate an electro-optic method to tune the correlated color temperature (CCT) of white light-emitting-diode (WLED) with a color conversion film, consisting of fluorescent dichroic dye doped in a liquid crystal host. By controlling the molecular reorientation of dichroic dyes, the power ratio of the transmitted blue and red lights of the white light can be accurately manipulated, resulti...

Color Matching of Blends Prepared From Black and White Fibers by Neural Networks (TECHNICAL NOTE)

The color of the blends of pre-colored fibers depends on the ratio of each fiber in the blends. Some theories have been introduced for color matching of blends of pre-colored fibers. Most however, are restricted in scope and accuracy. Kubelka and Munk presented the most applicable theory, which is still used in industry. In this work, the classical Kubelka-Munk method for color prediction of a ...

A submillisecond-response liquid crystal for color sequential projection displays

Fenglin Peng Abstract — We report Fangwang Gou Haiwei Chen Yuge Huang Shin-Tson Wu a new LC with low viscosity and high clearing point (Tc ~102 °C) for colorsequential projection displays. Using a 1.95-μm mixed-mode twisted nematic cell, the averaged grayto-gray response time is less than 1ms, which is ~3.6× faster than the current state of the art. Such a mixed-mode twisted nematic liquid-crys...
