Electrowetting element including a compound comprising a plurality of colorant moieties and a linker. The plurality of colorant moieties includes a first colorant moiety having a first net dipole and a second colorant moiety having a second net dipole. The plurality of colorant moieties are linked by and disposed around the linker so that the first net dipole and the second net dipole at least partially cancel each other.

Electrowetting element

Subject matter disclosed herein relates to arrangements and techniques that provide for improving contact angle measurement of a liquid droplet on an interface. An apparatus for measuring contact angles of a liquid droplet on a substrate comprises a platform configured to support the substrate and a camera configured to capture images of a liquid droplet on the interface. The apparatus further comprises multiple light sources to illuminate the liquid droplet along multiple direction and multiple optical paths to direct light illuminating the liquid droplet to the camera.
