Abstract: Touch sensitive displays are disclosed that can include circuitry that is segmented into multiple portions that can be independently operated. Touch sensitive display circuitry can be split in half with an upper portion and a lower portion that can each be independently operated. The separate circuitry portions can be used for performing display operations and for performing touch sensing operations. Display operations can be performed in one portion of the display while touch sensing operations are simultaneously performed in another portion of the display. Periodically, the operation being performed in a given portion of the display can be switched so as to alternatingly update that portion of the display and sense touch events in that region.

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.
