    Abstract: An electronic device may have a display overlapped by a display cover layer. Portions of the surface of the display and cover layer may have curved profiles. For example, a display cover layer may have transparent sidewall portions with curved surface profiles. The transparent sidewall portions of the display cover layer may include rounded corners having areas of compound curvature. A flexible display panel may be pressed over a mold to impart desired curvature (such as compound curvature) to the flexible display panel. To mitigate wrinkling in a flexible display panel molded to have compound curvature, a film may be included that absorbs force in the display panel. The film may have a coefficient of thermal expansion that is different than that of the display panel. Instead or in addition, the film may have portions with different Young's modulus magnitudes or different thickness magnitudes.

    IPC: G06F1/16

    Abstract: An electronic device display may have pixels formed from crystalline semiconductor light-emitting diode dies, organic light-emitting diodes, or other pixel structures. The pixels may be formed in a display panel having a single substrate or an array of display panel tiles. The display panel has inwardly facing display panel contacts that mate with corresponding outwardly facing interconnect substrate contacts on an interconnect substrate. The interconnect substrate may have areas with compound curvature that are overlapped by the display panel. To enhance flexibility of the interconnect substrate, the interconnect substrate may have flexibility enhancement openings and/or may be formed from a material with a low elastic modulus such as silicone or other elastomeric material.

    Abstract: An electronic device may have a display overlapped by a display cover layer. Portions of the surface of the display and cover layer may have curved profiles. For example, a display cover layer may have transparent sidewall portions with curved surface profiles. The transparent sidewall portions of the display cover layer may include rounded corners having areas of compound curvature. A flexible display panel may be pressed over a mold to impart desired curvature (such as compound curvature) to the flexible display panel. To mitigate wrinkling in a flexible display panel molded to have compound curvature, a backfilm may be included that absorbs compressive strains in the display panel. The backfilm may have a coefficient of thermal expansion that is higher than that of the display panel. Instead or in addition, the backfilm may have portions with different Young's modulus magnitudes or different thickness magnitudes.
