A capacitive fingerprint sensor is configured to be integrated in a display. The capacitive fingerprint sensor includes a plurality of transmitter electrodes. Each respective transmitter electrode including at least one transmitter conductor formed in a first metal layer of a sensor stack and disposed between pixels of a display. The capacitive fingerprint sensor further includes a plurality of receiver electrodes. Each respective receiver electrode including at least one receiver conductor formed in a second metal layer of a sensor stack and disposed between pixels of the display. The receiver electrodes have an orientation different from the transmitter electrodes.

In-display capacitive fingerprint sensor

A method comprises acquiring measured luminance levels at a measurement point of a display area for a plurality of test images displayed in the display area, and estimating one or more luminance levels at one or more corresponding luminance estimation points of the display area using the measured luminance levels. The method further comprises determining, based on the one or more estimated luminance levels, a correction parameter using the estimated one or more luminance levels.

Device and method for display module calibration

Aspects described herein include a method and associated processing system for a display having a plurality of pixels. The method comprises driving, using display circuitry, a plurality of pixels of a display device to display one or more test patterns. The display device is integrated into a manufactured input device. The method further comprises receiving field-set mura compensation data that is based on one or more images of the plurality of pixels. The one or more images are acquired responsive to displaying the one or more test patterns. The method further comprises writing the field-set mura compensation data to a memory of the input device. The field-set mura compensation data replaces or is stored along with factory-set mura compensation data.

Field recalibration of displays

Methods of encapsulating an environmentally sensitive device. The methods involve temporarily laminating a flexible substrate to a rigid support using a reversible adhesive for processing, reversing the reversible adhesive, and removing the device from the rigid support.

Method of encapsulating an environmentally sensitive device

A tool for depositing multilayer coatings onto a substrate. The tool includes a housing defining a vacuum chamber connected to a vacuum source, deposition stations each configured to deposit a layer of multilayer coating on the substrate, a curing station, and a contamination reduction device. At least one of the deposition stations is configured to deposit an inorganic layer, while at least one other deposition station is configured to deposit an organic layer. In one tool configuration, the substrate may travel back and forth through the tool as many times as needed to achieve the desired number of layers of multilayer coating. In another, the tool may include numerous housings adjacently spaced such that the substrate may make a single unidirectional pass. The contamination reduction device may be configured as one or more migration control chambers about at least one of the deposition stations, and further includes cooling devices, such as chillers, to reduce the presence of vaporous layer precursors. The tool is particularly well-suited to depositing multilayer coatings onto flexible substrates, as well as to encapsulating environmentally-sensitive devices placed on the flexible substrate.

Apparatus for depositing a multilayer coating on discrete sheets

A tool for depositing multilayer coatings onto a substrate. In one configuration, the tool includes a includes an in-line organic material deposition station operating under at least one of a pressure or temperature controlled environment. In another, it further is of a hybrid design that incorporates both in-line and cluster tool features. In this latter configuration, at least one of the deposition stations is configured to deposit an inorganic layer, while at least one other deposition station is configured to deposit an organic layer. The tool is particularly well-suited to depositing multilayer coatings onto discrete substrates, as well as to encapsulating environmentally-sensitive devices placed on the flexible substrate.

An improved barrier stack. The barrier stack is made by the process of depositing the polymeric decoupling layer on a substrate; depositing a first inorganic layer on the decoupling layer under a first set of conditions wherein an ion and neutral energy arriving at the substrate is less than about 20 eV so that the first inorganic layer is not a barrier layer, wherein a temperature of the substrate is less than about 150&#xb0; C.; and depositing a second inorganic layer on the first inorganic layer under a second set of conditions wherein an ion and neutral energy arriving at the substrate is greater than about 50 eV so that the second inorganic layer is a barrier layer. Methods of reducing damage to a polymeric layer in a barrier stack are also described.

Multilayer barrier stacks and methods of making multilayer barrier stacks

A method of making an encapsulated plasma sensitive device. The method comprises: providing a plasma sensitive device adjacent to a substrate; depositing a plasma protective layer on the plasma sensitive device using a process selected from non-plasma based processes, or modified sputtering processes; and depositing at least one barrier stack adjacent to the plasma protective layer, the at least one barrier stack comprising at least one decoupling layer and at least one barrier layer, the plasma sensitive device being encapsulated between the substrate and the at least one barrier stack, wherein the decoupling layer, the barrier layer, or both are deposited using a plasma process, the encapsulated plasma sensitive device having a reduced amount of damage caused by the plasma compared to an encapsulated plasma sensitive device made without the plasma protective layer. An encapsulated plasma sensitive device is also described.

Method of making an encapsulated plasma sensitive device

A method for cleaning the surface of magnetic disks prior to the deposition of a metal layer on the magnetic disk. The method includes the steps of first, placing a magnetic disk into a magnetron assisted DC plasma chamber. The plasma chamber includes a vacuum chamber, one or more targets, one or more magnets, a noble gas source, a target power supply, and a DC bias power supply. Next, a noble gas, for example argon, is introduced into the vacuum chamber via the noble gas source, and a DC glow discharge is generated in the vacuum chamber by supplying power to the one or more targets using the target power supply. Finally, the magnetic disk is etched when a negative voltage is applied to the magnetic disk using the DC bias power supply.
