Abstract: Embodiments of the present invention generally provide shield electrodes for shielding one or more conductive routing traces from one or more receiver electrodes in an input device comprising a display device integrated with a sensing device to reduce the capacitive coupling between the conductive routing traces and the receiver electrodes. The shield electrode may be configured to reduce the effect of an input object on the capacitive coupling between the conductive routing traces and the receiver electrodes. In other embodiments, end portions of common electrodes shield the receiver electrodes from the conductive routing traces, thereby reducing the capacitive coupling between the receiver electrodes and the conductive routing traces.

Abstract: A method and apparatus for operating an input device having a touch sensor and associated display device is discussed. While performing touch sensing, inactive transmitter electrodes of the touch sensor are electrically floated, and one or more source lines from the display device are operated to achieve shielding against interference, such as that coming from a backlight underneath the touch sensor.

Abstract: An electrode matrix that is used for capacitive sensing may be integrated into a display panel of an input device. In one embodiment, source drivers may be mounted on the display panel which drive the display signals and capacitive sensing signals into the display panel. In one embodiment, the capacitive sensing signals may be routed on traces or lines that are interleaved on the same layer as the source lines used for setting a voltage on the pixels in the display panel during display updating. Using the interleaved traces, the source drivers may drive the capacitive sensing signals in parallel to a plurality of the electrodes in the matrix in a predefined pattern that spans one or more sensing cycles.

Abstract: Embodiments of the invention generally provide an input device with display screens that periodically update (refresh) the screen by selectively driving common electrodes corresponding to pixels in a display line. In general, the input devices drive each electrode until each display line (and each pixel) of a display frame is updated. In addition to updating the display, the input device may perform capacitive sensing using the display screen as a proximity sensing area. To do this, the input device may interleave periods of capacitive sensing between periods of updating the display based on a display frame. For example, the input device may update the first half of display lines of the display screen, pause display updating, perform capacitive sensing, and finish updating the rest of the display lines. Further still, the input device may use common electrodes for both updating the display and performing capacitive sensing.
