摘要： Display structures and methods of assembly are described. In an embodiment, a display structure includes a display panel including a pattern of trenches extending at least partially through a backplane of the display panel, without extending past a matrix of LEDs in an overlying emission layer stack. The plurality of trenches can be formed in 2D to facilitate bending of the display panel into a 3D film curvature.

摘要： 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 on a display panel substrate. A display panel may extend continuously across the display or multiple display panels may be tiled in two dimensions to cover a larger display area. Interconnect substrates may have outwardly facing contacts that are electrically shorted to corresponding inwardly facing contacts such as inwardly facing metal pillars associated with the display panels. The interconnect substrates may be supported by glass layers. Integrated circuits may be embedded in the display panels and/or in the interconnect substrates. A display may have an active area with pixels that includes non-spline pixels in a non-spline display portion located above a straight edge of the display and spline pixel in a spline display portion located above a curved edge of the display.

摘要： 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 (24). The display panel has inwardly facing display panel contacts (56') that mate with corresponding outwardly facing interconnect substrate contacts (54) on an interconnect substrate (44). 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.

摘要： 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 comers 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.
