    The Yenisei project was defined by Color CNTRL Research B.V. to implement the white
    state stability of their electro-osmotic technology. For this project the focus was on smart
    windows and color panels as potential products. This one-year project was performed by
    an external specialist from the Technical University of Eindhoven.
    The white state stability issue was defined as a drop in the perceived transmittance of a
    display when the driving voltage is switched off. It is desired that the display transmittance
    remains the same or decreases gently, achieving a drop in the white state not visible
    for the human eye. Strict specifications for the transmittance drop were defined. The deliverables of the project were set as verified and tested solutions to this technological
    challenge. No chemistry related solutions were taken into consideration.
    During the course of the project, 10 solutions were proposed from which 7 were selected
    for testing.
    One of the tested solutions was ”driving with constant voltage”. The solution suggests
    that a gradual decrease of the driving voltage slows down the drop in transmittance of
    the white state. One key outcome of this solution was the fact that only the half of the
    standard diving voltage is needed to keep the transparent state of a display, which means 5 times less power consumption.
