Abstract: A borderless display utilizes a support frame having a bulged periphery (or outer portion), and a flexible electrophoretic display (EPD) structure that is curved at least partly around the support frame. The bulged outer portion of the support frame allows the flexible EPD structure to be wrapped around the outer portion of the support frame without damaging elements of the EPD structure in the process. Meanwhile, the center portion of the support frame can be made thinner, as compared to the thickness of the support frame at the bulged, outer portion. In this manner, the overall profile (in the z-direction) of the electronic device can be made as thin as possible without damaging fragile elements in the EPD structure.
