Abstract: Electrode configurations for reducing wobble error for a stylus translating on a surface of a touch sensor panel is disclosed. Electrodes associated with a more linear signal profile can correlate to lower wobble error. In some examples, electrodes can be configured such that the signal profile associated with each electrode is spread to be wider, and thus, more linear. In some configurations, electrodes can include two or more bars extending along the length of the electrode with each bar electrically connected to one another at one or both ends. Bars can be of non-uniform width or spacing. Some configurations can include a “split bar,” which can divide a bar lengthwise in order to improve optical uniformity. In some examples, electrodes can include projections which can interleave with corresponding projections in adjacent electrodes.

Abstract: A touch panel configured to compensate for negative pixel effect is disclosed. The panel can be configured to increase a capacitive sense signal, indicative of a touching or hovering object, in order to compensate for an increase in negative capacitance when the object is poorly grounded. To perform the compensation, the panel can be configured to have split sense lines so as to increase the number of electric fringe fields forming the sense signal, thereby providing a sense signal that is substantially stronger than the negative capacitance signal. Each sense line can be split into two or more strips.

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: Combined force and proximity sensing is disclosed. One or more sensors can concurrently sense a force applied by an object on a device surface and a proximity of the object to the surface. In an example, a single sensor can sense both force and proximity via a resistance change and a capacitance change, respectively, at the sensor. In another example, multiple sensors can be used, where one sensor can sense force via either a resistance change or a capacitance change and another sensor can sense proximity via a capacitance change.

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: The formation of metal traces in the border areas of a touch sensor panel to provide improved reliability, better noise rejection, and lower manufacturing costs is disclosed. The metal traces can be coupled to rows on the touch sensor panel in an interleaved manner, so that any two successive rows can be coupled to metal traces in border areas on opposite sides of the touch sensor panel. In addition, by utilizing the full width available in the border areas in some embodiments, the metal traces can be formed from higher resistivity metal, which can reduce manufacturing costs and improve trace reliability. The wider traces can also provide better noise immunity from noise sources such as an LCD by providing a larger fixed-potential surface area and by more effectively coupling the drive lines to the fixed potential.
