The present invention is an apparatus and method of manufacture for providing image capturing modules which can be embedded into thin displays (e.g., in laptop computers) while providing for improved image quality. In accordance with several embodiments, a webcam module embedded in a display has multiple positions. A first position (or a “rest” or “park” position) is the position of the webcam module when it is not in use. In this first position of the webcam module, it is in its most compact configuration, and lends itself to integration into a very thin display. In other positions, the webcam module has a more expanded configuration, thus leading to better image quality. Such an expanded configuration leads, amongst other things, to a larger depth of focus. In one embodiment, a stepped PCB is used to provide good image quality while maintaining a compact form factor as well as structural rigidity.
