Basic
Electrowetting Droplets.
The droplet on the left shows a basic experiment performed in an oil ambient, the droplet on the right shows clips from a high-speed camera after voltage was applied to the droplet and after it was released.

Electrowetting
Microprisms
The video shown at left is one of our earliest devices, but it the video nicely shows prism operation. See if you can notice between frames where we briefly bias the sidewalls with the same voltages and create lenslets. The video shown at right is for a recently created electrowetting microlens array.

Displays
The left and middle columns are various videos of our electrowetting displays. The video at left column bottom is actually a video of the very first pixels we fabricated. Some of our work from 2007 is shown in the video at far right, where cell-phone resolution pixels are driven by an active matrix backplane on the bottom glass substrate.

Self Assembly and Electrofluidics
Display
We dose liquid into ALL our devices via self-assembly. We do this for microprism arrays, displays, microwell arrays, etc.. These simple techniques all us to create arrayed devices of very small resolution, and still be able to reliably does liquids into the devices even if there are 1,000,000's of devices on a single substrate.

Electrowetting Microwells
Shown at left are oil:dye microwells and right are water:pigment microwells. These devices are also somewhat similar in structure to the retroreflector arrays we have created.
Spinodal Dewetting
NDL reported in 2007 that oil film breakup in electrowetting displays was fundamentally spinodal in nature. In the pixel at right see if you can notice some of the effects of differential Young-Laplace pressure after the oil film is broken up.

Spontaneous Channel Formation
A paper to be published soon, with more information coming at that time.
Light Wave Coupling
Ever wonder what it would look like if flat panel displays could be completely transparent in the off state (like a window)? Here we demonstrate with one of our partner companies this effect. The panel is 12" on a side. Several panels are layered and you are looking through an OFF panel (clear) to see the other panels when they are in the ON state.
