摘要： Compensation of pixels included in a touch sensor panel that generate erroneous readings (so called "negative pixels") due to a poor grounding condition of the object touching the touch sensor panel is disclosed herein. To compensate for the erroneous readings, sense lines of the touch sensor panel can include reverse driving circuits to facilitate calculation of an object-to-ground capacitance. If the calculated object-to-ground capacitance indicates the presence of a poor grounding condition, then the object-to-ground capacitance and detected pixel touch output values are used to estimate new pixel touch output values that are used instead of the detected pixel touch output values to determine touch event(s).

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： With respect to liquid crystal display inversion schemes, a large change in voltage on a data line can affect the voltages on adjacent data lines due to capacitive coupling between data lines. The resulting change in voltage on these adjacent data lines can give rise to visual artifacts in the data lines' corresponding sub-pixels. Various embodiments of the present disclosure serve to prevent or reduce these visual artifacts by applying voltage to a data line more than once during the write sequence. Doing so can allow erroneous brightening or darkening caused by large voltage swings to be overwritten without causing additional large voltage swings on the data line.

摘要： A touch sensitive device having circuitry to compensate for crosstalk from the device display to the device touch sensor panel is disclosed. The crosstalk compensation circuitry can include a downsampler and a crosstalk compensator. The downsampler can downsample a display image to a manageable size for transmission and processing and can then send the downsampled image to the crosstalk compensator so as to provide information about the display operation that can be used to estimate the expected amount of crosstalk caused by the display. The crosstalk compensator can estimate the amount of crosstalk based on the downsampled image and can then compensate a touch image captured by the touch sensor panel for the estimated amount, the touch image being indicative of a touch or hover event at the panel.

摘要： Clamping of a circuit element of a touch screen, such as a gate line of the display system of the touch screen, to a fixed voltage is provided. The circuit element can be clamped during a touch phase and undamped during a display phase of the touch screen. A gate line system of a touch screen can include a first transistor with a source or drain connected to a first gate line, a second transistor with a source or drain connected to a second gate line, and a common conductive pathway connecting gates of the first and second transistors. A synchronization system can switch the first and second transistors to connect the first and second gate lines to a fixed voltage during a touch phase, and can switch the first and second transistors to disconnect the first and second gate lines from the fixed voltage during a display phase.

摘要： Capacitive touch panels may include a plurality of positive voltage lines that are driven at a first phase. These positive voltage lines may be used to provide the drive capacitance signal sensed by one or more sense regions. The touch panels may also include a plurality of negative phase voltage lines that are driven at a phase that is different than the first phase. Both the positive and negative voltage lines may cross-under one or more sense regions. The negative phase voltage lines are able to counter act and reduce the static capacitance in the sense regions.
