Abstract: The use of multiple stimulation signals having one or more frequencies and one or more phases to generate an image of touch on a touch sensor panel is disclosed. Each of a plurality of sense channels can be coupled to a column in a touch sensor panel and can have one or more mixers. Each mixer in the sense channel can utilize a circuit capable generating a demodulation frequency of a particular frequency. At each of multiple steps, various phases of one or more selected frequencies can be used to simultaneously stimulate the rows of the touch sensor panel, and the one or more mixers in each sense channel can be configured to demodulate the signal received from the column connected to each sense channel using the one or more selected frequencies. After all steps have been completed, the demodulated signals from the one or more mixers can be used in calculations to determine an image of touch for the touch sensor panel at each of the one or more frequencies.

Abstract: Displays with integrated touch sensing circuitry are provided. An integrated touch screen can include multi-function circuit elements that form part of the display circuitry of the display system that generates an image on the display, and also form part of the touch sensing circuitry of a touch sensing system that senses one or more touches on or near the display. The multi-function circuit elements can be, for example, capacitors in display pixels of an LCD that are configured to operate as display circuitry in the display system, and that may also be configured to operate as touch circuitry of the touch sensing system. For example, one or more circuit elements of the display pixel stackup can form a conductive portion of the touch sensing system, such as a charge collector, which can be operated with switches and conductive lines to sense touch.

Abstract: Capacitive touch panels may include a plurality of positive voltage lines that are driven at a first phase. These positive voltage lines may be used to provide the drive capacitance signal sensed by one or more sense regions. The touch panels may also include a plurality of negative phase voltage lines that are driven at a phase that is different than the first phase. Both the positive and negative voltage lines may cross-under one or more sense regions. The negative phase voltage lines are able to counter act and reduce the static capacitance in the sense regions.

Abstract: A display having data lines that can be configured between a display mode and a touch mode is disclosed. The display can have sense regions for sensing a touch or near touch on the display during the touch mode. These same regions can display graphics or data on the display during the display mode. During display mode, the data lines in the sense regions can be configured to couple to display circuitry in order to receive data signals from the circuitry for displaying. During touch mode, the data lines in the sense regions can be configured to couple to corresponding sense lines in the regions, which in turn can couple to touch circuitry, in order to transmit touch signals to the circuitry for sensing a touch or near touch. Alternatively, during touch mode, the data lines in the sense regions can be configured to couple to ground in order to transmit residual data signals to ground for discarding.

Abstract: Capacitive multi-touch sensor panels in which both row and column traces may be formed on a single conducting surface are disclosed. These stack-ups may be made thinner and more flexible allowing them to be particularly well-suited for curved or other non-flat touch sensor panels, such as those that might be present on a mouse or other device designed to be grasped by a user's hand. Curved sensor panel arrays that may be formed from flat substrates are also disclosed. These sensor panel configurations may include channels around the periphery of the array. These channels allow the flat array to lie flat when applied to a curved surface, such as the inside of the curved surface. The pattern of the touch sensor elements may be adjusted across the array to avoid the channels.
