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: A display may have an array of pixels. The array of pixels may have a shape such as a circular shape or other shape with a curved edge. Display driver circuitry may supply data signals to the pixels using folded vertical data lines and bisected horizontal gate lines. Each folded vertical lines may have a first segment in a left half of the array and a second segment in a right half of the display. Curved coupling segments in an inactive area of the display may be used in joining the first and second segments. Display driver circuits may be provided in top and bottom portions of the inactive area to supply data to respective top and bottom portions of the array. Gate driver output buffers may have different strengths in different rows of the array.

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: 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.
