Abstract
Embodiments of the invention describe providing image focusing capabilities for a lens unit of an image capture system by disposing a solid state die over the lens unit. The solid state die may include a plurality of electrodes to receive a voltage or electric signal to generate an electric field. The refractive index of the solid state die will change in response to the generated electric field to focus the image or scene captured by the lens unit. The solid state die is mounted to a folded flexible printed circuit board in a housing or a molded housing having electrodes on its inner wall.
