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: Negative pixel compensation in a touch sensitive device is disclosed. The device can compensate for a negative pixel effect in touch signal outputs due to poor grounding of an object touching the device. To do so, the device can switch to a configuration to measure the grounding condition of the touching object and use the measurement to compensate the touch output values from the device accordingly. In the switched configuration, a first set of lines of the device can be switched between a coupling to a stimulation signal input to drive the device, a coupling to a capacitance signal output to output a signal indicative of the object's grounding condition, and a coupling to ground. A second set of lines of the device can be coupled to a touch signal output to output a signal indicative of the object's touch at the device. In addition or alternatively, in the switched configuration, the first set of lines of the device can be switched to function as the second set of lines and vice versa. The grounding signal can be applied to the touch signal to compensate for the negative pixel effect.

Abstract: Ground detection of a touch sensitive device is disclosed. The device can detect its grounded state so that poor grounding can be selectively compensated for in touch signals outputted by the device. The device can include one or more components to monitor certain conditions of the device. The device can analyze the monitored conditions to determine the grounding condition of the device. The device can apply a function to compensate its touch signal outputs if the device determines that it is poorly grounded. Conversely, the device can omit the function if the device determines that it is well grounded.

Abstract: An integrated touch screen display includes multi-function circuit element/s that form part of the display circuitry of the display system that generates an image on the display, and also form part of the touch sensing circuitry of a touch sensing system that senses one or more touches on or near the display. For example, one or more circuit elements of the display pixel stack can form a conductive portion of the touch sensing system, such as a charge collector, which can be operated with switches and conductive lines to sense touch. In an embodiment a common electrode xVcom415 in a fringe field switching LCD can serve as a multifunction circuit element. Using transistors S1, S2 and S3 the common electrodes can operate as a charge collected in a charge transfer capacitive touch sensing system. A xVcom Bridge 423 can connect xVcom of one pixel to be xVcom of an adjacent pixel. During a display phase transistor S1 417 performs switching of data lines 413 to connect data lines to pixel electrodes 416 and transistor S2 419 can switch xVcom lines. During touch operation S1 can be switched off and transistor S2 and transistor S3 can be switched to xVcom and data lines respectively and alternatively so as to operate the charge transfer capacitive sensor.

Abstract: A touch sensitive device detects its grounded state so that poor grounding can be selectively compensated for in touch signals outputted by the device. The device can include one or more components to monitor certain conditions of the device, such as resistor detectors, a monitor sensor, a proxitnity sensor, a perimeter sensor and/or a property sensor for objects in contact or near the device and an application sensor. The device can analyze the monitored conditions to determine the grounding condition of the device. The device can apply a function to compensate its touch signal outputs if the device determines that it is poorly grounded. Conversely, the device can omit the function if the device, which may be a mobile telephone, digital media player or personal computer determines that it is well grounded.

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: 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.
