Abstract: In some examples, a touch and force sensitive device includes integrated circuitry configured to attenuate noise in a first period of operation, and sense force of an object contacting the device in a second period of operation. In some examples, a touch and force sensitive device includes integrated circuitry formed from a same material layer, the material layer configured to detect a force of an object contacting the device in first one or more regions of the material layer, and configured to couple touch detection circuitry in second one or more regions of the material layer.

Abstract: Touch screens with ultra-thin stack-ups can provide for a lower profile device, can improve the optical image on the display by reducing the display to cover glass distance, and can reduce the weight of the device. In some examples, the thickness of the touch screen stack-up can be reduced and/or the border region reduced, by removing the flex circuit connection from the stack-up. A flexible substrate can be used to enable routing of touch electrodes to touch circuitry. In some examples including a shield layer, the thickness of the touch screen stack-up can be reduced by routing the shield layer to a shield electrode on the touch sensor panel. The shield layer can then be routed to touch sensing circuitry via the flexible substrate. In some examples, the touch sensor panel or a portion of thereof can be integrated with the polarizer.
