Abstract: Systems for detecting an amount and/or location of a force applied to a device using a piezoelectric film are provided. One example system can include a transparent piezoelectric film for generating an electric charge in response to a deformation of the film. Electrodes positioned on opposite surfaces of the piezoelectric film can be used to detect the generated electric charge and determine an amount and/or location of force applied to the film based on the generated electric charge. In another embodiment, the system can include a capacitive touch sensor for determining a location of a touch event on the device.

Abstract: An electronic device has a foldable display. First and second portions of an electronic device housing for the device may be joined using a hinge. A flexible display may overlap the first housing portion and the second housing portion and may bend along a bend axis as the first and second housing portions are rotated relative to each other using the hinge. The hinge may include toothed members such as gears and a rack member. The rack member may have a surface with curved portions. The gears may include rotating gears that walk along the curved portions of the rack member as the electronic device is folded and unfolded. The hinge may include gears that are fixedly attached to the first and second housing portions and that engage the rotating gears. Linkage members may hold together gears and the rack member.

Abstract: Systems and methods related to piezoelectric based force sensing in touch devices are presented. One embodiment, for example, may take the form of an apparatus including a touch device having a deformable device stack and a piezoelectric element positioned relative to the deformable device stack such that the piezoelectric element deforms with the deformable stack. Deformation of the piezoelectric element generates a signal having a magnitude discernable as representative of an amount of force applied to the touch device.

Abstract: An electronic device may have a touch screen display or other input-output device that includes transparent conductive electrodes. The transparent conductive electrodes may be formed from a material that has a relatively high index of refraction such as indium tin oxide. Surrounding layers of the touch screen display such as a touch sensor substrate and an underlying display layer may have lower index of refraction values. To prevent abrupt index-of-refraction discontinuities that lead to unwanted reflections and visible artifacts on the display, the transparent conductive electrodes may be embedded within a dielectric layer. The dielectric layer may have a graded index of refraction. The graded index of refraction may be varied continuously or in a stepwise fashion by adjusting the composition of materials that are incorporated into the dielectric layer as a function of position within the layer.
