  • Publication number: 20230352497
    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.
