Abstract: A touch sensor panel is disclosed. In some examples, the touch sensor panel comprises a plurality of touch node electrodes. In some examples, the touch sensor panel comprises a touch controller configured to drive and sense the plurality of touch node electrodes in a fully bootstrapped configuration to obtain a fully bootstrapped touch image, drive and sense the plurality of touch node electrodes in a second configuration, different from the fully bootstrapped configuration, to obtain a second touch image, the second touch image including an effect of water on the touch sensor panel, and determine a final touch image based on the fully bootstrapped touch image and the second touch image, the final touch image not including the effect of the water on the touch sensor panel. In some examples, the second configuration comprises a mutual capacitance configuration. In some examples, the second configuration comprises a partially bootstrapped configuration.

Abstract: A touch sensitive device that includes a touch sensor having an opaque passivation layer is disclosed. The opaque passivation layer can be made from an organic or inorganic material, such as acrylic. The opaque passivation layer can be positioned in the touch sensitive device between the cover material of the device and conductive traces located on the touch sensor to hide the conductive traces from the user's view and protect the conductive traces from corrosion. Processes for making the touch sensitive devices that include a touch sensor having an opaque passivation layer are also disclosed.

Abstract: Power consumption of touch sensing operations for touch sensitive devices can be reduced by implementing a coarse scan (e.g., banked common mode scan) to coarsely detect the presence or absence of an object touching or proximate to a touch sensor panel and the results of the coarse scan can be used to dynamically adjust the operation of the touch sensitive device to perform or not perform a fine scan (e.g., targeted active mode scan). In some examples, the results of the coarse scan can be used to program a touch controller for the next touch sensing frame to idle when no touch event is detected or to perform a fine scan when one or more touch events are detected. In some examples, the results of the coarse scan can be used to abort a scheduled fine scan during the current touch sensing frame when no touch event is detected.

Abstract: A touch input device configured to synchronize a stylus acquisition process with both a touch data acquisition process and a display refresh process is provided. The touch input device can include one or more processors that can synchronize the stylus data acquisition process to the touch data acquisition process by coordinating stylus scans to take place in between touch scans. The one or more processors can also virtual data banks to synchronize both the touch data acquisition and the stylus scan acquisition with the display refresh process.

Abstract: The border routing of conductive traces in devices, such as displays, touch sensor panels, and touch screens, to improve border area space usage, thereby reducing device size, and to reduce trace resistance, thereby improving device operation, is disclosed. The conductive traces can form a staggered stair-step configuration in the device border area, in which the average widths of the traces can be different from each other and each trace can have segments with different widths. The conductive traces can be coupled to an active area of the device to transmit signals to and from the active area in accordance with a device operation. The varying widths can help improve the border area space usage, reduce trace resistance, and reduce the differences in resistance between traces.

Abstract: Synchronization of display functions and various touch, stylus and/or force sensing functions for devices including a variable refresh rate (VRR) display is disclosed. In some examples, touch, stylus and/or force sensing functions can be synchronized with display frames and a display refresh rate can be adjusted by extended blanking of the display for one or more display frames. In other examples, touch, stylus and/or force sensing functions can be synchronized with display sub-frames and a display refresh rate can be adjusted by extended blanking of the display for one or more display sub-frames. Pre-warning synchronization signals can be generated to prepare one or more scan controllers to implement the appropriate scan events during and after extended blanking periods. Latency between the scan results and the corresponding image on the display can be corrected in software and/or firmware by time-stamping scan results or by dropping scan results from uncompleted scans.

Abstract: A touch sensitive device capable of detecting signals generated by a stylus and correcting the detected stylus signals for effects due to noise present on the device is disclosed. In one example, signals are taken from one or more electrodes that are a pre-determined distance away from an electrode in which a stylus signal is detected. The pre-determined distance can be empirically determined such that a noise estimate can be generated such that the electrodes have a higher probability of containing only noise that is highly correlated to the noise present on a detected stylus signal. The generated noise estimate is then subtracted from a detected stylus signal to reduce the effect of noise on the stylus signal.

Abstract: An electronic device can include an integrated touch and display chip that can operate in multiple power domains. For example, the integrated touch and display chip can operate in a guarded power domain during the touch operation and can operate in a system power domain during non-guarded display operations. In some examples, two power domains can include a guarded power domain and a system power domain, whose grounds can be differentiated by a guard buffer signal. In some examples, the guard buffer can be disposed between the integrated touch and display chip and a battery of the device. In some examples, the guard buffer can be disposed between the battery of the device and the chassis of the device.

Abstract: A touch sensor panel having column traces that can terminate at a short edge of a substrate is disclosed. A flex circuit can have a wide flex circuit portion extending the full width of the short edge that can bond to the bond pads on the top side of the substrate. It can be undesirable to have column traces (e.g., sense lines) and row traces (e.g., drives lines) cross over each other at the bonding area, and it can also be undesirable to have bond pads formed on directly opposing sides of the substrate because such areas can generate unwanted stray mutual capacitance and coupling of signals. Row traces can be routed to the same short edge of the substrate as column traces using wide conductive traces running along the borders of the substrate.
