A display device comprises a sensing subsystem configured to detect one or more conditions associated with touch input to the display device occurring via a contact of an input object at a surface of the display device. The display device further comprises a microphone system configured to receive sound, a logic machine, and a storage machine holding instructions. The instructions are executable by the logic machine to determine, based on the one or more conditions, a time of the contact; determine, based on at least the time of the contact, some characteristics of the contact; and generate an audio output via applying a selective attenuation to process sound received into the microphone system. The selective attenuation is selected based on the sonic characteristics and applied over a time interval beginning at the determined time of contact.

Selective attenuation of sound for display devices

A display device includes an array of display pixels having display pixel apertures that are periodic along two orthogonal directions, x and y, at spatial frequencies fand f, respectively. An array of electrodes is overlaid on the array of display pixel apertures. The array of electrodes is comprised of a metal mesh having openings that are periodic along a first direction u at an angle &#x3b8;relative to x, and along a second direction v at an angle &#x3b8;relative to y, and at spatial frequencies fand f. The array of electrodes is overlaid on the array of display pixels such that the parameter set {&#x3b8;, f, f, &#x3b8;, f, f} satisfies specific geometric criteria in order to minimize perceptible moir&#xe9; patterns.

Different lamination methods may be used to create a touch sensor with a darkened side of metalized film facing the user. One lamination method includes laminating a metalized film to an optically clear adhesive (OCA) layer such that an edge of the metalized film including the termination pads remain un-adhered to the OCA layer. Flex-tails may be bonded to the termination pads at a later time by bending up the un-adhered edge. Anisotropic Conductive Film (ACF) may be placed on the termination pads prior to laminating the metalized films. Flex-tails may be placed onto an OCA layer in a location where the termination pads on the metalized film will be located when laminated to the OCA layer. A strip of ACF may be placed on the flex-tail pads. The flex-tails may be bonded to the termination pads of the metalized film prior to the metalized film being laminated.

Electrode matrices for capacitive touch-sensing are provided. An electrode matrix may include a plurality of electrodes separated by gaps. Each electrode may include a plurality of spaced apart conductors electrically connected at opposed ends by respective tie structures. The conductors of each electrode may be electrically bridged at intervals by a plurality of jumpers. The electrode matrix may further include a plurality of pseudo jumpers positioned within the gaps and configured to be non-conductive across their entire lengths.

Electrode matrices for capacitive touch-sensing are provided. An electrode matrix may include a plurality of column conductors having a first end and a second end formed along a central longitudinal axis. The column conductor may further include a column zigzag structure extending between the first end and the second end. The electrode matrix may further include a plurality of row conductors having a first end and a second end formed along a lateral axis. The row conductor may further include a row zigzag structure extending between the first end and second end. The zigzag structure of each of the plurality of column conductors may cross the zigzag structure of each of the plurality of row conductors in respective crossing regions that are formed at an intersection of the longitudinal axis of each column conductor and lateral axis of each row conductor.

To address the above issues, a display device with a capacitive touch screen display having a touch surface in close proximity to a display stack is provided. The display may include a touch sheet with a top surface, a touch sensor having a matrix of capacitors formed of electrodes positioned below the touch sheet and configured to exhibit a change in capacitance of at least one of the capacitors in response to a touch on the top surface by a digit or stylus of a user, a display stack positioned below the matrix of capacitors and configured to emit light through a top surface of the display stack to travel in a light emitting direction through the matrix of capacitors and the touch sheet. A distance between the top surface of the touch sheet and the top surface of the display stack is between about 225 and 1500 micrometers.
