摘要： 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.

摘要： Embodiments described herein include a method for operating an input device by applying a charge voltage to a sense element through a first transistor that is between the sense element and a column output line and a first switch that is between the column output line and a drive voltage. The method also includes storing an electric charge on the sense element, wherein the electric charge comprises a magnitude corresponding to a feature of an input object. The method also includes driving a gate terminal of the first transistor low and disconnecting the charge voltage via the first switch. The method further includes transferring the electric charge to a feedback capacitor.

摘要： 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.
