Abstract: A display may have one or more bent portions. To increase the magnitude of curvature in a display and/or to allow for compound curvature in the display, a display panel may be partially formed in a planar state. The partial display panel is then bent to have desired curvature. After the partial display panel is bent, additional display components that are susceptible to damage during the bending process may be added to complete the display panel. A flexible printed circuit may be formed directly on the display panel using precise deposition of conductive material. By forming the flexible printed circuit layer-by-layer directly on the display panel, no substantive pressure needs to be applied to the display panel. Electrical connections may therefore be made to the display panel in regions of the display with high levels of curvature and/or with compound curvature without causing front-of-screen artifacts for the display panel.

Abstract: A touch screen (500) can include electrodes (520, 540) (e.g., first and second touch electrodes, reference electrodes) on opposite sides (e.g., top and bottom) of a substrate (510). In some examples, vias (618, 638) can be used to couple the touch electrodes (520, 540) to conductive connections (518, 538) of flex circuits (502, 522) such that the connections (604, 624) to the flex circuits (502, 522) can be on the same side of the substrate (510) even if the touch electrodes (520, 540) are on opposite sides of the substrate (510). The conductive filling material of the via (618) can make direct contact with the conductive connections (604, 624) of the flex circuits (502, 522), for example.

Abstract: Conductive traces may be conformally wrapped around the side of a display panel that includes an array of display pixels. The conductive traces may electrically connect contacts on an upper surface of the display panel to corresponding contacts on a flexible printed circuit that is attached to a lower surface of the display panel. The side-wrapped conductive traces may be interposed between first and second insulating layers. The flexible printed circuit may have a multi-step interface that is electrically connected to the side-wrapped conductive traces. A system-in-package including a display driver integrated circuit may be mounted to the flexible printed circuit. The system-in-package may include a plurality of redistribution layers that electrically connect contacts on the display driver integrated circuit to contacts on the flexible printed circuit.
