    Abstract: An electronic device may have a flexible display with portions that can be bent. The display may include an array of display pixels in an active area. Contact pads may be formed in an inactive area of the display. Display circuitry in the active area may exhibit a given stack height, whereas display circuitry in the inactive area may exhibit a stack height that is less than the given stack height. In particular, the contact pads may be formed directly on a multi-buffer layer that sits directly on a flexible display substrate. Passivation material may be selectively formed only at the edges of the contact pad on the multi-buffer layer. The multi-buffer layer may be formed at a distance from the edge of the flexible display substrate to minimize cracking in the multi-buffer layer.

    Abstract: Anisotropic conductive film (ACF) structures and manufacturing methods for forming the same are described. The manufacturing methods include preventing clusters of conductive particles from forming between adjacent bonding pads and that are associated with electrical shorting of ACF structures. In some embodiments, the methods involve use of multiple layered ACF materials that include a non-electrically conductive layer that reduces the likelihood of formation of conductive particle clusters between bonding pads. In some embodiment, the methods include the use of ultraviolet sensitive ACF material combined with lithography techniques that eliminate conductive particles from between neighboring bonding pads. In some embodiments, the methods involve the use of insulation spacers that block conductive particles from entering between bonding pads. Any suitable combination of the described methods can be used.

    Abstract: An electronic device may be provided with an organic light-emitting diode display with minimized border regions. The border regions may be minimized by providing the display with bent edge portions having neutral plane adjustment features that facilitate bending of the bent edge portions while minimizing damage to the bent edge portions. The neutral plane adjustment features may include a modified backfilm layer of the display in which portions of the backfilm layer are removed in a bend region. A display device may include a substrate, a display panel on the substrate having display pixels, and peripheral circuitry proximate the display panel and configured to drive the display pixels. A portion of the periphery of the substrate may be bent substantially orthogonal to the display panel to reduce an apparent surface area of the display device. The bent portion may include an electrode for communication with the peripheral circuitry.

    Abstract: An electronic device may be provided with a display such as an organic light-emitting diode display. The display may include an array of display pixels formed on a polymer substrate layer. The polymer substrate layer may include an contiguous layer of polyimide that forms a substrate layer in additional structures such as a polymer film and a flexible printed circuit. A first transition region may be interposed between the display and the polymer film, and a second transition region may be interposed between the polymer film and the flexible printed circuit. Metal traces may be formed on the polymer film and on the flexible printed circuit. A display driver integrated circuit may be mounted to the traces on the polymer film. The polymer film may form a U-shaped bend. The flexible printed circuit may be coupled to a printed circuit board in the device using hot bar solder connections.

    Abstract: Methods for controlling deformation of laminated display assemblies are described. The laminated display assemblies can include flexible layers. In some embodiments, the flexible layers are sensor layers. Methods involving the use of a thermal press and ultra violet (UV) curing procedure are described. In one embodiment, a thermal press method can be performed by placing a laminated display assembly including the flexible substrate, an ink layer, an adhesive, and a cover on a temperature controlled fixture. A mechanical press can apply pressure to the top of the laminated display assembly. The mechanical press can remove any planar deformity of the flexible layer and can redistribute portions of the adhesive. Following the mechanical pressing, the laminated display assembly can be exposed to UV light to cure the adhesive and thereby fix in place the planar state of the laminated display assembly.
