Abstract: Displays with touch sensing circuitry integrated into the display pixel stackup are provided Circuit elements, such as touch signal lines, drive lines, sense lines, grounding regions, in the display pixel stackups can be grouped together to form touch sensing circuitly that senses touch on or near the display An integrated touch screen can include multi-function circuit elements that can operate as circuitry of the display system to generate an image on the display, and can also form part of a touch sensing system that senses touch on or near the display The multi-function circuit elements can be capacitors in display pixels that can be configured to operate as storage capacitors/electrodes, common electrodes, conductive wires/pathways, etc of the display circuitry in the display system, and that may also be configured to operate as circuit elements of the touch sensing circuitry

Abstract: Methods and apparatus for switching the voltages supplied to the electrodes of pixels disposed within a liquid crystal display device. By reducing the frequency associated with an alternating voltage supplied to a first set of liquid crystal electrodes, the power required to drive the liquid crystal display device can be reduced. At the same time, a reordered schedule for updating rows of pixels in the liquid crystal display device can provide improved image quality.
