Microscopic Views

Here are a few videos showing the microscopic behavior of the ink. Click on images to download videos.

This shows the dielectrophoretic method of addressing. Colored droplets are either compressed (clear pixel) or dispersed (featureless on the video, blue pixel). For scale, the cylindrical spacer in the upper right portion of the frame is 10 microns in diameter.

Dielectrophoretic addressing in a TFT. Note that the ink is almost entirely ejected from the active areas, creating highly transmissive pixels in the clear state. Pixel size here is approximately 30 x 100 microns.
