US Patent 9568800 Thin border displays

A thin border display for an electronic device may comprise an optical assembly that includes a support frame and an electrophoretic display (EPD) structure attached to the support frame in a manner that allows for the display of the electronic device to exhibit a “thin border” or “borderless” look at a periphery of the electronic device. A portion of the EPD structure may at least partly curve around a curved portion of the support frame, the curved portion of the support frame being near the periphery of the support frame. In some embodiments, an electrode may be disposed at a periphery of the display to drive the margin of the display for achieving a thin border/borderless appearance. The EPD structure may include a backplane substrate that is either rigid or flexible.
