Abstract
In an electrowetting cell or system using the cell, electrode configuration and/or associated control of electrode drive signal(s) compensate for the impact of an external condition such as gravity, vibration or motion, which may otherwise cause distortion or aberration in the optical geometry of the fluid(s) of the electrowetting cell. The compensation technology may allow for larger electrowetting cell designs, whether lenses, prisms or other various electrowetting devices.
