    Abstract: 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.

    Abstract: A touch surface device having improved sensitivity and dynamic range is disclosed. In one embodiment, the touch surface device includes a touch-sensitive panel having at least one sense node for providing an output signal indicative of a touch or no-touch condition on the panel; a compensation circuit, coupled to the at least one sense node, for generating a compensation signal that when summed with the output signal removes an undesired portion of the output signal so as to generated a compensated output signal; and an amplifier having an inverting input coupled to the output of the compensation circuit and a non-inverting input coupled to a known reference voltage.

    Abstract: A touch screen including display pixels with capacitive elements is provided. The touch screen includes first common voltage lines connecting capacitive elements in adjacent display pixels, and a second common voltage line connecting first common voltage lines. The pixels can be formed as electrically separated regions by including breaks in the common voltage lines. The regions can include a drive region that is stimulated by stimulation signals, a sense region that receives sense signals corresponding to the stimulation signals. A grounded region can also be included, for example, between a sense region and a drive region. A shield layer can be formed of a substantially high resistance material and disposed to shield a sense region. A black mask line and conductive line under the black mask line can be included, for example, to provide low-resistance paths between a region of pixels and touch circuitry outside the touch screen borders.

    Abstract: Pre-stored no-touch or no-hover (no-event) sensor output values can initially be used when a sensor panel subsystem is first booted up to establish an initial baseline of sensor output values unaffected by fingers or other objects touching or hovering over the sensor panel during boot-up. This initial baseline can then be normalized so that each sensor generates the same output value for a given amount of touch or hover, providing a uniform response across the sensor panel and enabling subsequent touch or hover events to be more easily detected. After the initial normalization process is complete, the pre-stored baseline can be discarded in favor of a newly captured no-event baseline that may be more accurate than the pre-stored baseline due to temperature or other variations.

    Abstract: The use of multiple stimulation signals having one or more frequencies and one or more phases to generate an image of touch on a touch sensor panel is disclosed. Each of a plurality of sense channels can be coupled to a column in a touch sensor panel and can have one or more mixers. Each mixer in the sense channel can utilize a circuit capable generating a demodulation frequency of a particular frequency. At each of multiple steps, various phases of one or more selected frequencies can be used to simultaneously stimulate the rows of the touch sensor panel, and the one or more mixers in each sense channel can be configured to demodulate the signal received from the column connected to each sense channel using the one or more selected frequencies. After all steps have been completed, the demodulated signals from the one or more mixers can be used in calculations to determine an image of touch for the touch sensor panel at each of the one or more frequencies.

    Abstract translation: 传感器面板子系统首次启动时，最初可以使用预先存储的无触摸或无悬停（无事件）传感器输出值，以建立传感器输出值的初始基线，不受手指或其他触摸或悬停的物体的影响 启动期间的传感器面板。 然后可以对该初始基线进行归一化，使得每个传感器为给定量的触摸或悬停生成相同的输出值，从而在传感器面板上提供均匀的响应，并使得能够更容易地检测到随后的触摸或悬停事件。 在初始归一化过程完成之后，可以丢弃预先存储的基线，以利于新捕获的无事件基线，由于温度或其他变化，可能比预先存储的基线更准确。
