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: A portable electronic device has a device housing, and an electronic camera module in the device housing. The module has a focusing lens to focus light from a scene, an imaging sensor to receive the focused light, and an electro-optic variable aperture to allow different amounts of the light from the scene to reach the imaging sensor. The electro-optic variable aperture may include a first aperture stack placed on a transparent substrate and a second aperture stack placed on the first aperture stack. The first aperture stack defines a first aperture and the second aperture stack defines a second aperture that is larger than the first aperture. Each aperture stack includes a transparent conductive oxide layer that is common with the adjacent aperture stack. Alternatively the electro-optic variable aperture may include an aperture stack that has two transparent conductive oxide layer layers, where one layer is in the form of concentric annuli.

Abstract: An optically-transparent conductive structure is disclosed. The optically-transparent conductive structure can be used within a display stack of an electronic device. The optically-transparent conductive structure may be formed by depositing a metal nanowire layer that on a surface of a polarizing layer within the display stack. An encapsulation layer is disposed over the metal nanowire layer that protects the metal nanowire from corrosion. An electrical coupling is provided through or within the encapsulation layer and electrically couples to the metal nanowire layer. The electrical coupling is connected to an electrical circuit within the electronic device.

Abstract: Sputter deposition systems and methods for depositing film coatings on one or more substrates are disclosed. The systems and methods are used to prevent or reduce an amount of defects within a deposited film. The methods involve removing defect-related particles that are formed during a deposition process from certain regions of the sputter deposition system and preventing the defect-related particles from detrimentally affecting the quality of the deposited film. In particular embodiments, methods involve creating a flow of gas from a deposition region to a particle collection region the sputter deposition system such that the defect-related particles are entrained within the flow of gas and away from the deposition region. In particular embodiments, the sputter deposition system is a meta-mode sputter deposition system.

Abstract: Methods of fabrication of a touch sensor panel using laser ablation are provided. The fabricated touch sensor panel can have touch sensors disposed on a surface of a substrate. A fabrication method can include depositing a first conductive layer onto a substrate in a touch sensor region and a border region, depositing a second conductive layer onto the first conductive layer in the border region, and ablating the second conductive layer at removal locations in the border region to define border traces for providing off-panel connections to touch sensors in the touch sensor region. This fabrication method can advantageously provide touch sensors in a fabrication process with high throughput using low cost material and equipment.

Abstract: Processes for fabricating compact touch sensors for touch sensitive devices are disclosed. A process can include providing a touch sensor structure having a substrate, a first layer disposed on the substrate, and a second layer disposed on the first layer. The second layer can have an ablation fluence value that is lower than an ablation fluence value of the first layer. The process can include patterning the second layer with a laser emitting energy having a fluence value greater than or equal to the ablation fluence value of the second layer and less than the ablation fluence value of the first layer. The process can further include etching at least a portion of the first layer that was exposed during the patterning of the second layer. At least a portion of the second layer can then be removed by etching or laser ablation.
