Abstract
Techniques for simultaneous touch scanning and display updates are described herein. In an example embodiment, a device comprises a display and one or more integrated circuit (IC) controllers. A sensor array is integrated within the display. The display comprises a thin-film transistor (TFT) layer and a top polarizing layer, and the sensor array comprises transmit (TX) electrodes that are disposed between the TFT layer and the top polarizing layer. The one or more IC controllers are configured to simultaneously update a row of pixels in the display and to drive one or more of the TX electrodes to scan the sensor array while the row of pixels is being updated, where the one or more of the TX electrodes are not associated with the row of pixels that is being updated.
