摘要： A concurrent touch and negative pixel scan performed at a touch panel is disclosed. The concurrent scan can include sensing an object proximate to the touch panel and sensing a negative pixel effect, based the object's grounding condition, at the touch panel, at the same time. As a result, sense signals indicative of the proximity of the object and coupling signals indicative of the negative pixel effect's magnitude can be captured concurrently. Because the negative pixel effect can cause errors or distortions in the sense signals, the coupling signals can be used to compensate the sense signals for the negative pixel effect.

摘要： A touch sensor panels having segmented electrodes for both the drive and sense lines. The touch sensor panel may include a number of columns of sense electrodes and a number of rows of drive electrodes. Each of the drive and sense electrodes are connected to one of the metal bus lines using a connecting trace. Pixels on the touch sensor panel are formed by the unique pairings of individual drive electrodes and their adjacent sense electrodes. Electrically, the mutual capacitance of one touch-sensing pixel can be distinguished from the mutual capacitance of another touch sensing pixel because the two mutual capacitances are formed with combinations of different drive electrodes and sense electrodes. In one embodiment, the drive electrodes and sense electrodes in adjacent columns are staggered horizontally with respect to each other by half a Y-pitch of the electrodes.

摘要： Determination of phases of multiple stimulation signals to be simultaneously applied to a touch sensor panel is disclosed. A matrix may be determined that is invertible and has a gain greater than one, where each row of the matrix may represent a single step among multiple steps needed to compute values for generating an image of touch, each column of the matrix may represent a drive line of the touch sensor panel to be stimulated, and each element of the matrix may represent the phase of the stimulation signal to be applied to a particular drive line in a particular step. For each step, stimulation signals having phases in accordance with the matrix elements may be simultaneously applied to the drive lines of the touch sensor panel.

摘要： Pre-charging display screen sub-pixels, such as aggressor sub-pixels, prior to the application of a target data voltage to the aggressor sub-pixels is provided. In some examples, a target voltage of a sub-pixel in a previous row in the scanning order of the display can be used to pre-charge sub-pixels. The row of sub-pixels to be pre-charged can be switched on during the updating of another row of sub-pixels. In this way, for example, target voltages applied to data lines while an update row is connected to the data lines, e.g., to update the update row, can be applied to the row to be pre-charged as well.

摘要： Embodiments of the invention relate to correction of erroneous touch data on a touch sensor panel. Erroneous touch data may occur when a user is touching locations on the touch sensor panel but fails to be in good contact with another part of the device including the touch sensor panel. These erroneous readings may be statistically compensated for. A capacitance value that combines various external capacitances that may cause erroneous results can be calculated. Then, if necessary, received touch data can be modified to take into account the external capacitance. Accordingly, improved accuracy is provided for determining touch event(s) on a touch sensor panel.
