摘要： Methods and apparatus for normalizing the effects of the changes to the parasitic capacitive coupling that can occur in touch sensor panels so as to reduce or eliminate the appearance of erroneous touch events. In some embodiments, at some time prior to regular device use (e.g. during factory calibration), a conductive sheet is initially positioned so as to entirely cover a touch surface of a touch sensor panel. A set of sensed signals may be determined upon driving the drive lines and sensing the sense lines of the panel. Correctional coefficients may then be calculated based in part upon the difference between a sensed signal and an expected signal. The correctional coefficients may then be stored in the device and used to determine signal corrections for a set of measured signals during normal operation.

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.
摘要翻译：对于液晶显示反转方案，由于数据线之间的电容耦合，数据线上的电压变化很大可能影响相邻数据线上的电压。由此产生的这些相邻数据线上的电压变化可能导致数据线对应子像素中的视觉伪影。本公开的各种实施例用于通过在写入序列期间多次施加电压到数据线来防止或减少这些视觉伪影。这样做可能会导致由于大电压摆幅导致的错误增白或变暗而不会在数据线上造成额外的大电压摆幅。

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： The efficient incorporation of RFID circuitry within touch sensor panel circuitry is disclosed. The RFID antenna can be placed in the touch sensor panel, such that the touch sensor panel can now additionally function as an RFID transponder. No separate space-consuming RFID antenna is necessary. Loops (single or multiple) forming the loop antenna of the RFID circuit (for either reader or tag applications) can be formed from metal on the same layer as metal traces formed in the borders of a substrate. Forming loops from metal on the same layer as the metal traces are advantageous in that the loops can be formed during the same processing step as the metal traces, without requiring a separate metal layer.

摘要： A touch sensor panel having co-planar single-layer touch sensors fabricated on a single side of a substrate is disclosed. The drive and sense lines can be fabricated as column- like patterns in a first orientation and patches in a second orientation, where each column-like pattern in the first orientation is connected to a separate metal trace in the border area of the touch sensor panel, and all patches in each of multiple rows in the second orientation are connected together using a separate metal trace in the border area of the touch sensor panel. The metal traces in the border areas can be formed on the same side of the substrate as the patches and columns, but separated from the patches and column-like patterns by a dielectric layer.

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.

摘要： Devices having one or more sensors located outside a viewing area of a touch screen display are disclosed. The one or more sensors can be located behind an opaque mask area of the device; the opaque mask area extending between the sides of a housing of the device and viewing area of the touch screen display. In addition, the sensors located behind the mask can be separate from a touch sensor panel used to detect objects on or near the touch screen display, and can be used to enhance or provide additional functionality to the device. For example, a device having a sensor located outside the viewing area can be used to detect objects in proximity to a functional component incorporated in the device, such as an ear piece (i.e., speaker for outputting sound). The sensor can also output a signal indicating a level of detection which may be interpreted by a controller of the device as a level of proximity of an object to the functional component. In addition, the controller can initiate a variety of actions related to the functional component based on the output signal, such as adjusting the volume of the earpiece.
