Abstract
The examples herein relate to assembly techniques and structures for sealing and lateral pressure compensation techniques that can be utilized in, for example, an electrowetting cell. The electrowetting cell can include a substrate that supports a well filled with a liquid. The electrowetting cell can include a control channel electrode to control the liquid via an electric field and a circuit connection to drive the control channel electrode. A seal is coupled to a spacer to seal the well between the substrate and the transparent cover. An expansion space, exterior to the well, is formed with the coupling of the seal and the spacer. As the liquid or the gas thermally expands or contracts, the seal compensates laterally by deforming sideways in an empty space of the expansion space.
